Step 2: Adding the EPEL Repository
before adding this repository we should take an small overview of EPEL.
so basically EPEL is Extra Package for Enterprise Linux.

which creates, maintains, and manages a high-quality set of additional packages on CentOS. EPEL has an epel-release package that includes GPG

keys for package signing and repository information.
just follow the below command in the terminal for add this repository

sudo yum install epel-release

Step3 : Install PhpMyAdmin
we have enable EPEL Repository ,now we have to install phpmyadmin by using followinng command.

sudo yum install phpmyadmin

Step 4 : Configuration
so for doing configuration first of all we need to have grant remote access.
We are going to make changes in the config file.


For that, we can get into the config file by using the below command.

vim /etc/httpd/conf.d/phpMyAdmin.conf

once the command is executed we will see the below lines which is shown in the below image.

Step 5 : Edit in phpmyadmin.conf file
In the above image, wecan see the line Require ip. The default value will be 127.0.0.1.
we need to replace the IP string with our machine IP.

  • To update the change , press “i”.
  • Replace that “Require ip” with the IP of your machine.
  • Saving the changes made in the config file, enter “:wq“.
  • Then exit from the phpMyAdmin.conf file by pressing ESC Key.

the changes are updated in the phpMyAdmin.conf file.

Step 6 : Restart the Apache Web Server
Now we need restart the apache web server to sync up the updated phpMyAdmin.conf file with Apache Webserver.

Once this is done, we are ready to start using phpMyAdmin.
use the following command to restart the apache web server.

systemctl restart httpd

After installation of phpMyAdmin

so we have successfully installed the phpmyadmin in our CentOS.
to check the GUI (Graphics user interface) of phpmyadmin.

go to the browser and type http://127.0.0.1/phpmyadmin . so the default IP is 127.0.0.1 so you must replace it with your machine IP.

Setup Login Credentials
You can set your credentials (Username and Password) in a below-mentioned manner.

First, we need to get into the phpMyAdmin installation directory by using below command.

/etc/phpMyAdmin

Here you can find the below mentioned file.

config.inc.php

Now we are going to create your credentials in this file. By using below command we can edit the config.inc.php file.

vim config.inc.php

Edit the file with your own credentials. As we did before, for Saving the changes made in the config file, enter :wq. And then exit from the config.inc.php file by pressing ESC key.
