Install Nginx on CentOS 9 Stream - Step by step guide ?



Nginx   (Engine X) is the most popular, powerful web server software that can be used on your server. It is also known for its high performance and low memory usage. In addition to its HTTP server capabilities, NGINX can also function as a proxy server for e-mail (IMAP, POP3, and SMTP) and a reverse proxy and load balancer for HTTP, TCP, and UDP servers.

Steps to Install and configure Nginx on CentOS 9 Stream

1. Perform System Update 

To begin, ensure that your system is up-to-date with the below command:

2. Install Nginx on the system 

By default, Nginx is available on the CentOS 9 Stream base repository. Now we run the following command to install Nginx to your system:

Once the installation is complete, now enable Nginx (to start automatically upon system boot), start the webserver, and verify the status using the commands below:

$ sudo systemctl start nginx
$ sudo systemctl enable nginx
$ sudo systemctl status nginx

To verify the Nginx version, use the following command to confirm:

$ nginx -v


3. Configure Firewall 

If your server is protected by a firewall you need to open both HTTP (80) and HTTPS (443) ports:

$ sudo firewall-cmd --permanent --zone=public --add-service=http 
$ sudo firewall-cmd --permanent --zone=public --add-service=https
$ sudo firewall-cmd --reload 


4. Confirm Nginx Installation 

Once successfully installed, open http://your-IP-address  in your browser of choice, and you will see the default Nginx welcome page .


5. Nginx Configuration File's Structure 

You don't need to configure Nginx upon installation. However, you should know the location of the configuration files and the Nginx root directory in case you need to modify the configuration:

  • Nginx configuration directory:  /etc/nginx
  • Nginx root directory:  /usr/share/nginx/html
  • Master/Global configuration file:  /etc/nginx/nginx.conf
