yum install httpd

Now start and enable Apache

systemctl start httpd
systemctl enable httpd

Step 3. Install MariaDB

Now we can start install MariaDB Server using this command

yum install mariadb mariadb-server

Start MariaDB service and enable it during startup

systemctl start mariadb
systemctl enable mariadb

Is this ok [y/d/N]:

Restart Apache

systemctl restart httpd

Check if PHP correctly installed

Create new file called info.php under /var/www/html directory

nano /var/www/html/info.php

Now paste this line to it

<?php phpinfo(); ?>

Now open web browser and type the server ip address with info.php. For example in my case:

http://10.34.0.215/info.php

Done, now we have a working LAMP Server on CentOS 7 server. Thanks for reading this how to install LAMP on CentOS 7 Server. Cheers
