Updating System Packages on CentOS
It is always recommended that you update the system to the latest packages before beginning any major installations. This is done with the command below:

sudo yum update

Installing Nginx
Install Nginx using the CentOS package manager yum as shown below:

sudo yum install nginx

Checking Nginx Version
After installation, you can check the installed version of the Nginx web server on your CentOS 7 server by issuing the following command:

sudo nginx -v 

Step 2: Install phpMyAdmin
Install phpMyAdmin using the CentOS package manager yum as shown below:

sudo yum -y install phpmyadmin php

Step 3: Configure phpMyAdmin
After successfully installing phpMyAdmin, we are going to create a virtual host configuration as phpMyAdmin does not automatically create one itself.

Create a virtual host file named phpMyAdmin.conf in the /etc/nginx/conf.d.

sudo nano /etc/nginx/conf.d/phpMyAdmin.conf

Add the following making changes to the domain name. You can replace it with your own domain name or your server's IP Address.

server {
        listen   80;
        server_name php.cloudwaferlabs.com.ng;
        root /usr/share/phpMyAdmin;

location / {
        index  index.php;
        }

## Images and static content is treated differently
        location ~* ^.+.(jpg|jpeg|gif|css|png|js|ico|xml)$ {
        access_log        off;
        expires           30d;
    }

location ~ /\.ht {
        deny  all;
        }

location ~ /(libraries|setup/frames|setup/libs) {
        deny all;
        return 404;
    }

location ~ \.php$ {
        include /etc/nginx/fastcgi_params;
        fastcgi_pass 127.0.0.1:9000;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME /usr/share/phpMyAdmin$fastcgi_script_name;
                    }
    }

Ensure to save before closing the file.

Next, restart the services:

sudo systemctl restart nginx

Install PHP-FPM Install php-fpm as shown below:

sudo yum install php-fpm

Next, restart php-fpm as shown below:

sudo systemctl restart php-fpm

Next, access phpMyAdmin from the browser on your domain name or server's IP address.
