Configure phpMyAdmin

Now, you need to configure web server to serve phpMyAdmin on network. Create Apache configuration file for phpMyAdmin and edit in text editor:

vi /etc/httpd/conf.d/phpmyadmin.conf 

add the below content to file.
Alias /phpmyadmin /usr/share/phpmyadmin

<Directory /usr/share/phpmyadmin/>
AddDefaultCharset UTF-8
<IfModule mod_authz_core.c>
# Apache 2.4
<RequireAny>
Require all granted
</RequireAny>
</IfModule>
</Directory>

<Directory /usr/share/phpmyadmin/setup/>
<IfModule mod_authz_core.c>
# Apache 2.4
<RequireAny>
Require all granted
</RequireAny>
</IfModule>
</Directory> 

Alias /phpmyadmin /usr/share/phpmyadmin

<Directory /usr/share/phpmyadmin/>
AddDefaultCharset UTF-8
<IfModule mod_authz_core.c>
# Apache 2.4
<RequireAny>
Require all granted
</RequireAny>
</IfModule>
</Directory>
<Directory /usr/share/phpmyadmin/setup/>
<IfModule mod_authz_core.c>
# Apache 2.4
<RequireAny>
Require all granted
</RequireAny>
</IfModule>
</Directory>

Save your file and close it. The systems with SELinux enabled needs to set proper permissions to allow SELinux policies

chcon -Rv --type=httpd_sys_content_t /usr/share/phpmyadmin/*

after making all the changes, make sure to start the Apache service to reload all settings.

systemctl restart httpd.service
