Tutorial installation Nginx on CentOS 8

To introduce one of the most popular web servers in the world, today we are going to present tutorial installation Nginx on CentOS 8. It is responsible for hosting some of the largest and most popular sites on the internet. In most cases, Nginx is more resource-friendly than Apache which could be used as a web server or reverse proxy.

Tutorial installation Nginx on CentOS 8

1- Installing the Nginx Web Server

First, you need to use the DNF package manager. It is a new default package manager on CentOS 8.

2- Adjusting Firewall Rules

To allow external connections on your Nginx web server, you need to adjust the firewall settings, which runs on port 80 by default.

So enter the below command to permanently enable HTTP connections on port 80:

sudo firewall-cmd --permanent --add-service=http  

Now, if you need to check the HTTP firewall service was added correctly or not, run the following:

sudo firewall-cmd --permanent --list-all  

The output should be similar to below:

public    target: default    icmp-block-inversion: no    interfaces:     sources:     services: cockpit dhcpv6-client http ssh    ports:     protocols:     masquerade: no    forward-ports:     source-ports:     icmp-blocks:     rich rules:

Reload the firewall service to apply the changes:

sudo firewall-cmd --reload  

You installed the Nginx server successfully now.

3- Checking your Web Server

To find your server’s public IP address, run the following command

ip addr show eth0 | grep inet | awk '{ print $2; }' | sed 's/\/.*$//'  

To verify the accessible IP address run below command.

curl -4 icanhazip.com

Then, type the result address in your web browser, you would be taken to Nginx’s default landing page:
