OpenSUSE install Brotli module for Nginx

How do I install or add Brotli compression support to Nginx on OpenSUSE Linux to speed up my webpages and apps?

Brotli is a free and open-source generic-purpose lossless compression algorithm that compresses data using various methods. It is similar in speed to deflate or gzip but offers more dense compression for Apache or Nginx web server.
Nginx does not support Brotli, but we can install a module developed by Google called ngx_brotli to add support to Nginx. This page explains how to add or install Brotli support to Nginx on an OpenSUSE Linux server 15.2 to speed up webpages.

Let us install nginx and nginx-module-brotli.

Step 1 – Installing nginx on OpenSUSE

I am using openSUSE Leap version 15.2. I am going to install nginx/1.16.1 as follows:
sudo zypper install nginx vim-plugin-nginx
See “How to install and use Nginx on OpenSUSE Linux server” for more info.

Step 2 – Installing Brotli module for Nginx on OpenSUSE

Next, type the following command to install Brotil on OpenSUSE for freshly installed Nginx:
sudo zypper install nginx-module-brotli

Step 3 – OpenSUSE nginx config for Brotli

Edit the /etc/nginx/nginx.conf, run:
sudo vi /etc/nginx/nginx.conf
Add/edit as follows after worker_processes auto; line:

load_module lib64/nginx/modules/;
load_module lib64/nginx/modules/;

Here is how my config file looks:

user  nginx;
worker_processes auto;
# load_module lib64/nginx/modules/;
# load_module lib64/nginx/modules/;
load_module lib64/nginx/modules/;
# load_module lib64/nginx/modules/;
load_module lib64/nginx/modules/;
load_module lib64/nginx/modules/;
error_log  /var/log/nginx/error.log;
#error_log  /var/log/nginx/error.log  notice;
#error_log  /var/log/nginx/error.log  info;
pid        /run/;
worker_rlimit_nofile 65535;
events {
    worker_connections   65535;
    use epoll;
    multi_accept on;
http {
    include       mime.types;
    default_type  application/octet-stream;
    log_format  main  '$remote_addr - $upstream_cache_status - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';
    access_log  /var/log/nginx/access.log  main;
    charset utf-8;
    sendfile on;
    tcp_nopush on;
    tcp_nodelay on;
    keepalive_timeout 65;
    types_hash_max_size 2048;
    client_max_body_size 16M;
    server_tokens off;
    log_not_found off;
    include conf.d/*.conf;
    include vhosts.d/*.conf;

Step 4 – Turn on brotli support for Nginx on OpenSUSE

Finally add the following in your server context. For instance I added the following to my /etc/nginx/vhosts.d/ file:

brotli on;
brotli_comp_level 6;
brotli_static on;
brotli_types application/atom+xml application/javascript application/json application/rss+xml
             application/ 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/
             image/x-icon image/x-win-bitmap text/css text/javascript text/plain text/xml;

Step 5 – Restart or reload Nginx web server

Now that we installed and configured the Brotil module for Nginx. Check Nginx server config file for syntax errors:
nginx -t
We will see confirmation as follows:

nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

No errors means we can gracefully restart Nginx web server after changes made:
sudo systemctl reload nginx
Check status of the Nginx server:
sudo systemctl status nginx

  Process: 539 ExecStartPre=/usr/sbin/nginx -t (code=exited, status=0/SUCCESS)

    Tasks: 0
   CGroup: /system.slice/nginx.service
           ├─  543 nginx: master process /usr/sbin/nginx -g daemon off;
           ├─68340 nginx: worker process
           └─68341 nginx: worker process

Step 4 – Test it

Open the terminal and type the following curl command to see if your website support content encoding using Brotli. The syntax is:
curl -sILH 'Accept-Encoding: br'

Testing Brotli support Nginx on OpenSUSE server

Related: How to find if a website using gzip / deflate compression using curl on Linux and Unix

Another option is to open Firefox/Chrome developer tools and look for the network tab. You must see Content-Encoding: br headers. That also confirms Brotil is working correctly on OpenSUSE Linux for the Nginx web server. For example:

Summing up

And there you have it, and we added Brotli support for Nginx on the OpenSUSE Linux server. Please see ngx_brotli documentation on Github.
