Our Life Together  >  Thoughts  >  Adding Brotli to an Already-built NGINX Instance  —  { code }

Do you have a running instance of NGINX and wanted to add Brotli compression? What if you don’t want to recompile a custom web server from source or replace your auto-updating repo-installed version? You can create dynamic Brotli modules which upgrade whenever NGINX does.

The bash script below explains the installation steps. Feel free to study and execute the codes step-by-step. That may help you troubleshoot any peculiarities in your system. Otherwise, simply run the script.


You may choose to automate the installation by simply running the script above. In its default settings, it will process the version number you will pass to it. To get your NGINX’s version number run this command:

nginx -v
nginx version: nginx/1.17.1

Since the version number in this example is 1.17.1, after you have downloaded the bash script above, go to the directory where the script is and run these commands:

chmod +x mkbrotli
./mkbrotli 1.17.1

You may now chill and relax as the script automagically downloads, builds, and installs the dynamic modules for you. If the script runs through errors please let me know in the comments below so I may make adjustments to it.

Activating the modules

Now that we have the modules, there are two configuration steps needed to activate Brotli compression. First, load the modules in NGINX’s main configuration file (mine was at /etc/nginx/nginx.conf). You can get your config file path by running this command:

nginx -V 2>&1 | grep -o 'conf-path=[^ ]*' | sed 's/conf-path=//'

Now edit NGINX’s conf file. Outside any block { ... }, maybe on the top section of the file, add these lines:


load_module modules/ngx_http_brotli_filter_module.so;
load_module modules/ngx_http_brotli_static_module.so;

# http {
#   ...
# }

Second, activate Brotli (and set its configuration directives, aka settings) either inside the http block of NGINX’s conf file, or the server block of your domain configs (e.g. files in nginx/sites-enabled/). As for me, I placed these directives in the nginx/snippets/ folder and called them via include in my domain configs.

Auto-update with NGINX

One potential problem with dynamic modules is when NGINX automatically upgrades via a package manager (e.g. apt, yum, or pacman). If you’re like me, all upgrades in my server are automated by scripts. You see, dynamic modules are version-specific. NGINX is set not to load modules that were built for a different version. So how will Brotli modules automatically upgrade together with NGINX?

The answer is to hook on the package manager during upgrades. In apt this may be a two- or three-step process:

  1. Hook to apt and call a worker script. (Alternatively, the hook could directly call mkbrotli and thus skip the need for a worker script.)
  2. The worker script calls one or more build scripts to update the dynamic modules.
  3. Build scripts will build and install the new modules right before NGINX upgrades.

Here is my hook file in /etc/apt/apt.conf.d/:


The worker script I use:


And finally the build script for this one is… (drum roll please)… of course mkbrotli. 😉 I hope that Brotli could be natively supported by NGINX in the future. It’s awesome. For now, we have this workaround. Enjoy the compression!

Google PageSpeed

Another project that aims to speed things up on the web is Google’s best-practices optimization called PageSpeed. I also made a Bash script to automate installation of PageSpeed on a running NGINX server. If you’re interested, check out this post: Adding PageSpeed to an Already-running NGINX Instance.

I get this error on nginx test

module “/usr/share/nginx/modules/ngx_http_brotli_filter_module.so” is not binary compatible in /etc/nginx/nginx.conf

Any ideas?

    Majal Mirasol · July 28, 2019 at 5:49 pm

    Hi Nigel! We should supply to the script the same version of NGINX we are running. Have you checked via nginx -v? The warning will also show the version number the module was built for, and your running NGINX’s version number. Can you please post the full warning message here along with the mismatched version numbers?

      Lowi · August 8, 2019 at 10:13 pm

      Hi, thanks for the script. I get the same error and I’m sure I installed the correct version

      Sucessfully built Brotli for NGINX 1.14.0 in /usr/lib/nginx/modules

        Majal Mirasol · August 8, 2019 at 10:21 pm

        That’s interesting… I’m pretty sure it works in my system. In fact it is running on this very website’s server. Hmmm… I’ll try to look more into this. Can you please supply more relevant details of your system? It may help us pinpoint and troubleshoot this issue. Thanks for the help!

        Looking again, I’d just like to confirm also that your test command should be: $ sudo nginx -t rather than $ nginx -t?

        Just guessing. Or the problem may be deeper than this… Thank you for your inputs! 🙂

          Scott · August 31, 2019 at 3:00 pm

          I got the same issue. It’s because you need to configure the module with the same options as nginx -V in the system (which is a lot when using debian bionic for example) – once I updated the script to contain the extra config options it worked

            Majal Mirasol · August 31, 2019 at 3:42 pm

            Hi Scott! Nice find. The configure step flag --with-compat is supposedly designed to handle that. But I think I read somewhere that it may not also work with certain configurations of NGINX. Thanks for pinning this. I’ll soon update the script which will include flags from nginx -V. Is it also okay if you could post how your configure command looked like? I and the readers here really appreciate all the help! 🙂

            Majal Mirasol · September 3, 2019 at 12:00 am

            Hello Scott! I’ve just updated the script. Please find new section confparams in it. 🙂 Thanks for your help!

        Majal Mirasol · September 2, 2019 at 11:55 pm

        Hi Lowi! A comment by Scott identified the culprit: your NGINX was likely configured without the --with-compat flag. I’ve updated the script where you can now choose to load the configure parameters of the installed NGINX in your system. Please see section on confparams and uncomment one of the commands that will work for you. Have a good day!

          Remco · September 12, 2019 at 8:55 pm

          Hi Majal, i keep getting the binary not compatible error, even with uncommenting one of the 3 confparams you provided in the script.

            Majal Mirasol · September 15, 2019 at 8:38 pm

            Hi Remco! It appears that the source of this issue is because NGINX could be just be configured in so many different ways. My NGINX comes vanilla from Ubuntu’s repos and works out of the box without even using the confparams part of the script. It seems that you have a customized build of NGINX. You may likely troubleshoot your issue by playing with the values of confparams. How about feeding confparams directly with your configuration parameters starting from --prefix= up to the end of the line? What I also usually do with bash scripts is to run the commands step-by-step in a terminal and manually check for errors. I’m sorry but I cannot test your issue since we are using different configurations of NGINX. We will appreciate it if you could post back your findings about your specific setup. It will be helpful to other readers who may also be using custom NGINX builds. Enjoy your day!

SeCrEt BoY™ · September 30, 2019 at 2:18 am

Hook to apt and call a worker script. (Alternatively, the hook could directly call mkbrotli and thus skip the need for a worker script.)
The worker script calls one or more build scripts to update the dynamic modules.
Build scripts will build and install the new modules right before NGINX upgrades.

I have copied 2 your files to /etc/apt/apt.conf.d/05nginxmodules and /usr/local/sbin/nginx-mod-preinstall
And what do I need to do next sir?
And finally the build script for this one is… (drum roll please)… of course mkbrotli. >>> how to build?
Thanks for help!

    Majal Mirasol · September 30, 2019 at 6:03 am

    Hi SeCrEt BoY! If you copied those two files in their proper directories, and if mkbrotli is placed in /usr/local/sbin/ then all you have to do is wait until NGINX upgrades and check if the apt hook works. Of course you will need to confirm first if the mkbrotli script is working well with your system, that is, if it runs and installs without issues.

    On your other question if I understood correctly, did you mean how to run mkbrotli and make it build Brotli? After you copied mkbrotli to /usr/local/sbin/ and made sure it is executable, just type this in the terminal: $ /usr/local/sbin/mkbrotli and see whether it will be successful or not.

    I hope this helps.

somuch · November 18, 2019 at 3:29 pm

Hi, I’m new to Ubuntu and Nginx. Already installed a few VPS on my own. Reading this tutorial I can understand how to install Brotli, but I only partially understand about updating/upgrading part.

On your last part of tutorial about upgrading Nginx, I can upgrade Nginx if I follow those 3 steps (Hook, Worker Script, and Build Script). But on your build script, on last part, I shouldn’t restart Nginx when it’s hooked? I often restart Nginx because I change nginx conf sometimes, or restarting ubuntu when creating snapshot etc. Isn’t it fine to restart Nginx even if it’s hooked as long as it’s not upgraded?

Another question about hooking, I just need to put those 3 scripts? No need to send command through ssh?


    Majal Mirasol · November 18, 2019 at 3:43 pm

    Hi somuch! Thanks for dropping by.

    Question 1 on restart: There is no need for the build script to restart NGINX if it is part of the hook since apt will automatically restart NGINX after a successful upgrade. What the apt hook does is when a new version of NGINX is ready to be installed (upgraded) it calls the Brotli build script. Once the script finishes, it proceeds in upgrading NGINX. After which, apt will cause the new version of NGINX to be started which should match the Brotli module version that the build script just made.

    Question 2 on apt hooks and ssh: I think you mean that in sending commands through ssh, you refer to interactive commands you send directly to the server. If yes, then the hooks are non-interactive commands that sit as files in your server until a trigger starts them. In this case, a trigger is started when apt realizes that NGINX is bound to be upgraded. You don’t have to be there in an ssh connection for this to happen. The server should automatically perform this without user interaction.

      somuch · November 18, 2019 at 5:22 pm

      For question 1
      I see, it’s getting clearer now. So what you mean on build script line #73 # Start/restart NGINX. specifically only when upgrading? So I can still use systemctl reload nginx as I always do as long as it’s not on upgrading process?

      For question 2, yes, the interactive command.Ok, so I just need to put the files in place.

      Anyway, what will happen when Nginx not loading this Brotli module after upgrade (in case I missed something)? Will it serve gzip? Serving empty files? Or not serving file at all? Because on the config, Brotli configuration still on.

      Thanks for the quick reply!

        Majal Mirasol · November 18, 2019 at 9:55 pm

        Question 1:
        Yes, you may do that. Or you can just edit the script and uncomment the line on restarting NGINX. I tried to make this script as understandable as possible so others can play around and improve on it.

        Question 2:
        If the script fails to build, then there will be a mismatch on the module version and NGINX version. This will prevent NGINX from starting at all. So there will be no NGINX running.

        I hope this clarifies your questions. 🙂

          somuch · November 19, 2019 at 1:12 pm

          Hi, I just tried to install Brotli, I followed the steps above EXCEPT for auto update with Nginx part. I got this error when trying to restart Nginx nginx: [emerg] dlopen() "/usr/share/nginx/modules/ngx_http_brotli_filter_module.so" failed (/usr/share/nginx/modules/ngx_http_brotli_filter_module.so: cannot open shared object file: No such file or directory) in /etc/nginx/nginx.conf:6

          Upon manually checking the module folder, the Brotli module isn’t there, both of them.

          Then I checked the bash script run on SSH, I get this https://pastebin.com/S0wsDZy6
          Several things not found, and at the end said ./configure: error: the HTTP gzip module requires the zlib library although I already have zlib library (I tried to install it apt install zlib1g and turns out I already have it).

          At the last lines it’s concluded that the install failed
          make: *** No rule to make target 'modules'. Stop.
          !! configure or make failed, exiting...

          Any idea about this? Thanks!

            Majal Mirasol · November 19, 2019 at 1:30 pm

            Hi! Looks like you have a number of errors there. Would you like to try to run the commands one-by-one on a terminal and address each error message if any? We’ll be interested to know where the trouble lies and how it may be fixed.

              somuch · November 19, 2019 at 2:04 pm

              Ok, I’ll try, running the command on bash manually right? I’ll start it with `ngver=1.16.1′ as mine is that version.

              Anyway, this is DigitalOcean VPS, Nginx built from DO repo.

                Majal Mirasol · November 19, 2019 at 2:08 pm

                Right. I’ve always wanted to check out DO, but never had the time. Please let us know what you’ll find out will work. Enjoy learning!

                  somuch · November 19, 2019 at 2:15 pm

                  I just ran it, put ngver=1.16.1 but I didn’t change any ${ngver} because I think already supplied from the first statement, is this correct?

                  When I ran this command [ ${confparams} ] && nice -n 19 ionice -c 3 ./configure --add-dynamic-module=../ngx_brotli "${confparams}" || nice -n 19 ionice -c 3 ./configure --with-compat --add-dynamic-module=../ngx_brotli
                  A lot of things not found, and then exiting SSH when running this command nice -n 19 ionice -c 3 make modules || { echo '!! configure or make failed, exiting...'; exit 4; }

                  When I redo all the steps, when I arrived at that last command, I removed the exit part, and I get this result:
                  make: *** No rule to make target 'modules'. Stop.
                  !! configure or make failed, exiting...

                    Majal Mirasol · November 19, 2019 at 2:23 pm

                    I think you should not move forward with succeeding commands when one of the commands fail. It looks like your configuration step has a number of missing dependencies. It will be good to address those as it will prevent the module from being properly built.

somuch · November 19, 2019 at 2:27 pm

Continuing, I fixed the problem! yay! GZIP module for HTTP not working despite I already installed ZLIB because I still don’t have its dependencies, so I do this apt-get install libpcre3 libpcre3-dev zlib1g zlib1g-dev libssl-dev as I found here https://askubuntu.com/questions/980145/cant-add-nginx-module-requires-zlib. Now the bash script run successfully, and nginx -t is OK. Trying Brotli now.

    Majal Mirasol · November 19, 2019 at 2:30 pm

    Congratulations! 🙂

      somuch · November 19, 2019 at 5:07 pm

      Brotli is working now, reducing 166KB web page (around 90KB is non media files) to 160KB. Don’t know about the actual speed improvement.

      I’m using W3TC as caching plugin, it seems buggy on Brotli support. Despite smaller file size, it takes longer on waiting time before download, as if it always create Brotli on the fly while it actually already has Brotli files cached. Another thing is, for HTML files, it shows 2 accept encoding header, br and gzip, separated on 2 different header. On GTMetrix, it download the uncompressed file instead. Sigh…

      Do you know any good caching/minify plugin?

        Majal Mirasol · November 20, 2019 at 8:31 am

        It tried a few plugins before, including W3TC, Varnish, Redis, Memcached, etc. But I eventually ended up using NGINX’s proxy_cache for local caching and Cloudflare’s CDN as the cloud cache. For me this takes away load from the server by not installing additional components into the system and keeping it as lean as possible.

Maxim · December 5, 2019 at 5:56 am

Thanks, friend! It’s works! 🙂
But I had one error (while trying to execute the file):
“error: unable to execute ./mkbrotli: No such file or directory”
I found a solution here: https://unix.stackexchange.com/questions/144718/sudo-unable-to-execute-script-sh-no-such-file-or-directory

    Majal Mirasol · December 5, 2019 at 11:21 am

    Thanks! Oh really? Text encoding issue? 🙂 I just checked my file and so far so good. It’s made purely in Linux. So I’m not sure where the encoding change was introduced, whether in the CDN (not likely), or if the file passed through a Windows machine…? Anyways, I’m glad the script works for you.

      Maxim · December 5, 2019 at 4:38 pm

      Yeah, I copied “ctrl+c” to a file in windows. And then uploaded it to the server. I am newbie 🙂 This is of course my mistake.

    Hi Davide! Sorry it didn’t work for you. Does your warning message include the mismatched version numbers? Would you mind showing us?

      Davide Prevosto · May 1, 2020 at 8:08 pm

      Hi Majal,

      unfortunately there isn’t any other error message other then the “binary compatible” one. I already use your script in the past, without any error. I do not understand, maybe issue it is causing by a particular NGINX module.

      This is the nginx -V output.

        Majal Mirasol · May 1, 2020 at 11:27 pm

        Hi Davide! We recently updated the script, specifically now found on line 52. Were you able to test with the newer script? Did the script throw any error messages before it performed the build process?

          Davide Prevosto · May 2, 2020 at 12:49 am

          Hi Majal, thank you for your reply.
          I already use your last version, also few minutes ago. I can’t see any error.

          This is the sucessully message:

          Sucessfully built and installed latest Brotli for NGINX 1.18.0
          Modules can be found in /usr/lib/nginx/modules
          Next step: Configure dynamic modules and reload/restart NGINX.

          No errors were shown before the end of the script.

          Thank you

            Davide Prevosto · May 2, 2020 at 12:51 am

            PS. Pay attention at your website cache system: for example new comments are not shown after a reply. I needed to add a query string to invalidate your page cache 😉

              Majal Mirasol · May 2, 2020 at 3:51 pm

              Thanks for the heads up. 🙂 Supposedly commenters should not receive a cached page. But looks like that’s not the case. I use Cloudflare workers. BTW, when I do CTRL + F5, it loads up the fresh page. I’ll look into it. Thanks!

              Now on the script, I’ll see if I can spin up a 1.18.0. I’m still on 1.16.1. 🙂

          Davide Prevosto · May 2, 2020 at 3:57 pm

          I was finally able to upgrade our BROTLI modules, without your bash script. I did run manually. I don’t know yet which module causes the issue, maybe I did something wrong.

            Majal Mirasol · May 2, 2020 at 4:24 pm

            Happy to hear that. 🙂 So that means the modules properly installed? We’d appreciate feedback when you’ll be able to find out what went wrong. Thanks a lot!

              Davide Prevosto · May 2, 2020 at 4:37 pm

              Yes Majal, Brotli is fully working on our server, with NGINX 1.18.0
              Unfortunately I wasn’t able to use your script (I always used it, since months). Thanks for sharing your knowledge, I envy you a lot 🙂

                Sweet Katarina (@Kata_Du_Coudont) · May 21, 2020 at 12:58 pm

                How did you do that?

                  Davide Prevosto · May 21, 2020 at 2:28 pm

                  Hello @Kata_Du_Coudont,

                  I have manually compiled the module, trying to remove the dynamic NGINX modules (nginx -V to list them)

Strike · May 9, 2020 at 6:37 am

You need to work on your SEO because this article was nearly impossible to find but the content here is GOLDEN. Too many articles assuming I want to bake my own nginx + brotli cake but I just wanted to adhoc brotli to my existing install. Thank you so much.

    Majal Mirasol · May 9, 2020 at 6:55 am

    Thanks for the compliment. When I realized this post is helpful, I reposted this article at dev.to and Medium with canonicals pointing back here. But well, it looks like not a lot found it so interesting I guess… Your tip is very much appreciated. 🙂 Have a fine day!

Lee Tea · May 10, 2020 at 1:03 pm

Thank you, this is very helpful!

Tried everything, uncommenting setting confparams, running without params at all. It’s building but

sudo nginx -t

I have installed it using this guide.
Anyway, thanks for you work.

    Majal Mirasol · May 18, 2020 at 9:23 pm

    I’m glad that worked for you Yussup. And it’s good to see more articles being written for this topic. I wasn’t able to find one when I jumped on this a year ago. Thanks for sharing that link. Have a good day keep safe!

Sweet Katarina (@Kata_Du_Coudont) · May 21, 2020 at 3:30 pm

Hi Majal,
I just today installed brotli on nginx 1.18.0. I’ve spend about 3 hours till it worked. I’ve used your script few months ago for 1.16.1 version and it worked somehow, now it dont, giving me a “is not binary compatible” error. So i have a few notes:

1) custom moduledir should me after auto_detection, because it sometimes not correct. I’m using fedora 30, and nginx configured with
but it’s loading modules only from /usr/share/nginx/modules. I dont know why. So autodetection doesn’t work.

2) The error in your script is in $confparam passing, somehow the quot appears in the configure arguments. It impossible to notice unless you do actual “make” command.

the GOOD system nginx show this:

Notice that quote after –prefix begins, and end till the end of string. I dont know how to fix it, but the problem is there. When i configured all that string manually – the “make modules” gived me good .so files without errors.

    Sweet Katarina (@Kata_Du_Coudont) · May 21, 2020 at 3:48 pm

    Yep. I finally fixed it. You should change 54 line

    [ “${confparams}” ] && nice -n 19 ionice -c 3 ./configure –add-dynamic-module=../ngx_brotli “${confparams}” || nice -n 19 ionice -c 3 ./configure –with-compat –add-dynamic-module=../ngx_brotli
    to this
    [ “${confparams}” ] && nice -n 19 ionice -c 3 “./configure –add-dynamic-module=../ngx_brotli ${confparams}” || nice -n 19 ionice -c 3 ./configure –with-compat –add-dynamic-module=../ngx_brotli

      Majal Mirasol · May 21, 2020 at 4:25 pm

      Hi Sweet Katarina! Awesome find! I just adjusted the code to implement your suggestion in line 53. I tested it and it works! Also, about your --prefix, I made another entry that hopefully will match your custom NGINX prefix. It is in line 24. Thank you for sharing your debugging here. 🙂

solut2000 · May 28, 2020 at 2:23 pm

Looks awesome!! I’ll try it!

solut2000 · May 29, 2020 at 1:05 am

It works like charm!
But I need more packages.
apt install libperl-dev libpcre3 libpcre3-dev libssl-dev openssl libgeoip-dev zlib1g-dev libxslt1-dev git python2.7 python-dev brotli libtool autoconf automake

    Majal Mirasol · May 29, 2020 at 5:16 am

    Thank you for letting us know that it works solut2000. 🙂 As well as your package requirements. Have a good day and keep safe!

Daniel L · August 14, 2020 at 2:11 pm

Thanks for the script! It worked well for me on Debian 10.
One minor issue I have with it is that it defaults to the Nginx module directory (eg. /usr/lib/nginx/modules), however /usr/lib/ should only ever be used for libraries managed by the system’s package manager. Manually compiled things should always go into /usr/local/. Because of that, I feel like it’d be a good idea to default the script to /usr/local/lib/nginx/modules. What do you think?

    Majal Mirasol · August 14, 2020 at 2:59 pm

    Hi Daniel! Thank you for your good suggestion. I like being standardized as well. From the comments, it became clear to me that the majority of the errors when running this script is because there are so many different builds of NGINX. (Well, freedom of open source.) To minimize the errors, the script tries to automatically figure out the modules path from the build configurations of the currently installed NGINX. In this way, it can adapt to where your specific NGINX build will be looking for modules by default.

    If you noticed the line # moddir=/path/to/modules/directory, there is the possibility of setting one’s own preferred modules directory manually.

    Thanks for stopping by. Life is indeed full of compromises. Stay safe!

Mufaddal B · August 14, 2020 at 7:40 pm

I have the binary not compatible issue coming even after many builds. Please find the link to check what steps are taken.

    Hi Mufaddal! Thanks for not easily giving up. That’s right, there’s an error in your logs: ionice: failed to executeNo such file or directory. What I sometimes do when things go wrong is to do the steps manually, line by line, to make sure there’s no error in each step of the way. Do you think you could do that troubleshooting? There are also comments here on how to resolve the binary not compatible error. Please try them, and see if one of those works for you. 🙂

      configuring additional dynamic modules
      adding module in ../ngx_brotli
      + ngx_brotli was configured
      adding module in debian/extra/njs/nginx
      ./configure: error: no debian/extra/njs/nginx/config was found

      I receive this above error. Can you please help.

          Checked above link but that is not the issue as the error shows full path.

          I tried removing that module from confparams and then ran the cmd again, now its showing error: no Debian/extra/ngx_pagespeed/config was found

          I dont know whether removing these modules from confparams will resolve the issue or installing these modules one by one and trying to install Brotli. Cant seem to figure a way out.

Finally I got it working.
These are the steps I followed

nginx -v
apt-add-repository -y ppa:hda-me/nginx-stable
apt-get install brotli nginx-module-brotli
nano /etc/nginx/nginx.conf


#include /etc/nginx/modules-enabled/*.conf;
user www-data;
worker_processes auto;
pid /run/nginx.pid;

load_module modules/ngx_http_brotli_filter_module.so;
load_module modules/ngx_http_brotli_static_module.so;

inside of http block

gzip on;
gzip_disable "msie6";

gzip_vary on;
gzip_proxied any;
gzip_comp_level 6;
gzip_buffers 16 8k;
gzip_http_version 1.1;
gzip_types text/plain text/css application/json application/javascript text/xml application/xml application/xml+rss text/javascript image/svg+xml;

brotli on;
brotli_comp_level 4;
brotli_types text/plain text/css application/json application/javascript text/xml application/xml application/xml+rss text/javascript image/svg+xml;
brotli_static on;

Save the file.

nginx -t
service nginx restart

Thanks for the push in the right direction that this post gave me! After much fiddling with which config parameters to provide, and no luck with the help of your script (from which I just picked out the relevant commands rather than running directly), I ended up just looking at the source for the ngx_brotli module, and there is, helpfully, a README which says:

You will need to use exactly the same ./configure arguments as your Nginx configuration and append --with-compat --add-dynamic-module=/path/to/ngx_brotli to the end, otherwise you will get a “module is not binary compatible” error on startup. You can run nginx -V to get the configuration arguments for your Nginx installation.

So I had a look at all of the config parameters that nginx -V showed on my setup: Nginx 1.18.0 on Ubuntu 20.04, installed via the nginx-extras package. The parameters show that, on whatever machine that package was built, the build directory is /build/nginx-5JShor/nginx-1.18.0, and there are additional modules in /build/nginx-5JShor/nginx-1.18.0/debian. You can get the latter files from [1], which is listed on [2] as one of the sources for nginx-extras.

I replicated the build setup for the Ubuntu package and was then able to build the Brotli module successfully. However, replicating the entire setup and then running make modules results in a lot of extra modules being compiled that we don’t need, because we already have them; they came with nginx-extras. As such, we can remove all of the --add-dynamic-modules parameters that appear in nginx -V, and we should keep all the rest. Doing this greatly reduces compilation time.

We can also compile in one of our own directories such as ~/build (rather than somewhere such as /build which only root can access) by changing the debug parameter -fdebug-prefix-map that is passed to GCC as appropriate.

Overall, what I did is given in the script [3]. Hopefully this helps someone in a similar situation. Thanks again for this post!
