LAMP - Linux, Apache, Mysql, PHP

LAMP is a group of software applications used together to run a dynamic website. They include Linux, Apache, MySQL, and PHP. They have to be installed on your VPS (Virtual Private Server) to run the dynamic website.

Requirements for LAMP

  • A VPS plan running CentOS 7
  • A non-root user with Sudo privileges

To setup:

Update your CentOS 7 server
Run sudo yum update

Install Apache

  • Using the Yum package manager, run the command sudo yum install httpd
  • After a prompt appears to confirm installation, press Y followed by pressing enter to continue.
  • Run the command to start Apache sudosystemctl start httpd.service

To confirm installation, enter your public IP address in a browser. The initial software installation is now complete, and the following Apache web page is what you can now see:

Centos Apache Default Page

Next, activate Apache to start during system startup by running sudosystemctl enable httpd.service

Install MariaDB Database

The additional packages need installing on our CentOS server by running the commands sudo yum install mariadb-server mariadb after which you confirm installation by pressing Y then Enter.

Run this command sudosystemctl start mariadb to start the service.

LAMP: Secure MariaDB

There is a need to remove the anonymous user and test the database while also configuring other settings by running sudomysql_secure_installation
A prompt will ask you to enter your MariaDB root password, at which point you will press 'enter' as you haven't set a password yet.
During the MySQL setup, a series of questions will be on the screen, and you just need to follow the answers below.

Set root password? [Y/n] Y
New password: Enter your password here
Re-enter new password: repeat your password
Remove anonymous users? [Y/n] Y
Disallow root login remotely? [Y/n] Y
Remove test database and access to it? [Y/n] Y
Reload privilege tables now? [Y/n] Y

A success message will appear as shown
… Success!

Cleaning up the MYSQL part of LAMP

All done! If you’ve completed all of the above steps, your MariaDB Installation should now be secure.
To autostart the database during system Startup, run sudo systemctl enable mariadb.service

LAMP: Install PHP

Run the command sudo yum install php php-mysql by using the yum package installer.
Confirm the installation, by pressing Y then Enter.
Restart Apache web server for it to work with PHP by running sudo systemctl restart httpd.service

Test PHP

To test PHP on our CentOs 7 Server, create a file at ‘/var/www/html/’ (default website created by Apache) using a nano editor.

Install nano by running sudo yum install nano. Create ‘info.php’ by running sudonano /var/www/html/info.php

A blank text file should appear, just copy paste the content below on the page:

<?php
phpinfo();
?>

After, press CTRL + X, Y and Enter to save the changes
Remember to replace the ‘IP address’ part with your CentOS 7 server’s public IP address.
You should see the below page on the browser if the installation was successful.
