Enabling Brotli Compression on existing NGINX web server on Ubuntu 22.04

brotli_nginx

1) SSH into the server as a root user
2) Install the required dependencies. Run apt install cmake libpcre3 libpcre3-dev
3) Run wget "https://nginx.org/download/nginx-$(nginx -v 2>&1 | awk -F/ '{print $2}' | sed 's/(Ubuntu)//' | tr -d '[:space:]').tar.gz"
4) Run tar -xzf nginx-{{ version }}.tar.gz
5) Run git clone --recurse-submodules -j8 https://github.com/google/ngx_brotli 
6) cd ngx_brotli/deps/brotli && mkdir out && cd out
7) Run cmake -DCMAKE_BUILD_TYPE=Release -DBUILD_SHARED_LIBS=OFF -DCMAKE_C_FLAGS="-Ofast -m64 -march=native -mtune=native -flto -funroll-loops -ffunction-sections -fdata-sections -Wl,--gc-sections" -DCMAKE_CXX_FLAGS="-Ofast -m64 -march=native -mtune=native -flto -funroll-loops -ffunction-sections -fdata-sections -Wl,--gc-sections" -DCMAKE_INSTALL_PREFIX=./installed ..
8) Run cmake --build . --config Release --target brotlienc
9) Run cd ~/nginx-{{ version }}
10) Run ./configure --add-module=/root/ngx_brotli
11) Run make && make install
12) Run ./configure --with-compat --add-dynamic-module=/root/ngx_brotli
13) Run make modules
14) Run cp objs/ngx_http_brotli_static_module.so /usr/lib/nginx/modules/
15) Run cp objs/ngx_http_brotli_filter_module.so /usr/lib/nginx/modules/
16) Open `/etc/nginx/nginx.conf` file and add the following directives above the http and events block:

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

17) If you want to enable Brotli compression to specific site, open /etc/nginx/sites-available/{{ domain }} and add the following 
  configuration inside `/` block:
  
  `
    ...
    server {
      ...
        location / {
          ...
          brotli on;
          brotli_comp_level 6;
          brotli_static on;
          brotli_types application/atom+xml application/javascript application/json application/vnd.api+json application/rss+xml
             application/vnd.ms-fontobject application/x-font-opentype application/x-font-truetype
             application/x-font-ttf application/x-javascript application/xhtml+xml application/xml
             font/eot font/opentype font/otf font/truetype image/svg+xml image/vnd.microsoft.icon
             image/x-icon image/x-win-bitmap text/css text/javascript text/plain text/xml;
       }
      ...
    }
  `
  
  18) To enable Brotli compression for all the sites, add the following configuration to `/etc/nginx/nginx.conf` file inside `http` block.
  
  `
    ...
    http {
      ...
      brotli on;
      brotli_comp_level 6;
      brotli_static on;
      brotli_types application/atom+xml application/javascript application/json application/vnd.api+json application/rss+xml
             application/vnd.ms-fontobject application/x-font-opentype application/x-font-truetype
             application/x-font-ttf application/x-javascript application/xhtml+xml application/xml
             font/eot font/opentype font/otf font/truetype image/svg+xml image/vnd.microsoft.icon
             image/x-icon image/x-win-bitmap text/css text/javascript text/plain text/xml;

  `
