How to Install Nginx On CentOS 8

How To Install Nginx on CentOS 8

On this article we will discuss how to install NginX on CentOS 8 and configuring firewall for HTTP port.


Beside Apache Web server, Nginx is one of the most popular web servers which is often used to handle the load of some of the largest sites on the Internet. Nginx pronounced “engine x” is an open-source, high-performance HTTP and reverse proxy server. It can be used as a standalone web server, load balancer, content cache, and reverse proxy for HTTP and non-HTTP servers. On this article we will learn how to install NginX on CentOS linux operating system.

For uninstalling/removing Nginx from CentOS system tutorial has been discussed on How to Unistall Nginx from Centos 7 article.


To install NginX on CentOS 8, then we have to fulfill the prerequisites, as mentioned below :

  • CentOS 8 System with sufficient disk space
  • Non-root user with sudo privileges
  • Active firewall installed on your server
  • There is no Apache or any other process running on port 80 or 443

Installing Nginx Web Server

The Nginx package is available in the default CentOS repositories, so we don’t need to add it to the repository first. The installation on CentOS 8 will be using dnf package manager, sudo dnf install nginx, as shown below :

[ramans@localhost ~]$ sudo dnf install nginx

Install Nginx on CentOS

After the installation is completed done, then we enable and start NginX services, by submitting command line : sudo systemctl [enable | start | status] nginx

[ramans@localhsost ~]$ sudo systemctl enable nginx
[sudo] password for ramans:
[ramans@localhsost ~]$ sudo systemctl start nginx
[ramans@localhsost ~]$ sudo systemctl status nginx

Adjusting The Firewall

As mentioned above, if CentOS 8 has shipped with FirewallD as the default firewall solution. Than we have to adjust the firewall settings in order to allow external connections on our Nginx web server, which r

uns on port 80 by default. We will permanently enable HTTP connections on port 80 and HTTPS connections on port 443. For this purpose, we just submit the command line below :

[ramans@localhost ~]$ sudo firewall-cmd --permanent --add-service=http
[ramans@localhsost ~]$ sudo firewall-cmd --permanent --add-service=https

To verify, if the ports are already enable just hit the command line below : sudo firewall-cmd --permanent --list-all as shown below :

[ramans@localhsost ~]$ sudo firewall-cmd --permanent --list-all
target: default
icmp-block-inversion: no
services: cockpit dhcpv6-client http https postgresql ssh
masquerade: no
rich rules:
sudo firewall-cmd --permanent --list-all

Testing Web Server

Now, we can test our Nginx installation, by opening http://IP_ADDRES in web browser. We should see the default Nginx welcome page, as below shown :

Nginx test page


So far, we have installed Nginx web server on CentOS 8 Linux operating system. By now, we can deploy an applications above it.
