In this post we are going to learn how to install LAMP stack on CentOS 7. LAMP stands for (Linux, Apache, MySQL/MariaDB, PHP).
- Linux which is Operating System
- Apache which is Web Server
- MySQL/MariaDB which is Database
- PHP is scripting language to serve dynamic content
All of these are open source and free to use. Each piece of the stack is mandatory for creating fully functional dynamic website.
Pre-requisites
- CentOS Server running
- SSH Access with Root Privileges

Step 1 – Update Packages
First of all, Login with your CentOS 7 Server & escalate the privileges to root. Before installation of LAMP stack, update your repository & software packages by running below commands on your CentOS 7. In CentOS default package manage is yum, so we shall use it to update & upgrade our repos.
#yum update && yum upgrade
When prompted, press y to continue upgradation process.
Step 2 – LAMP Stack Install Apache
Now that your repository & software packages are upgraded, now install apache by entering below commands in your CentOS 7 server terminal.
#yum install httpd
When prompted, press y to continue installation process. In CentOS, services when installed are not started & enabled by-default, you have to manually enable & start the service by executing below commands.
#systemctl enable httpd #systemctl start httpd
Apache service should be active & enabled, like so.
Step 3 – Update Firewall Rules
Firewalld is the defualt CentOS 7 firewall, we need to enable Apache2 access through firewall. Here is our turtoial on UFW Firewall to learn more about it.
Firewalld is enabled by-default in CentOS & you will need to open port for HTTP traffic by using the command:
Below command will open port for HTTP & HTTPS traffic respectively:
#sudo firewall-cmd --permanent --zone=public --add-service=http #sudo firewall-cmd --permanent --zone=public --add-service=https
Finally, restart the firewall to enable the new settings:
#sudo systemctl restart firewalld
Now if you visit your server IP Address, Apache CentOS 7 Default Page should appear.
Step 4 – LAMP Stack MySQL Installation
To install MySQL, type following command in your terminal using sudo rights.
#sudo yum install mysql-server
Now check mysql service status, it should be enabled & Active. If it is not Active & enabled, copy below commands & paste in your terminal.
#sudo systemctl start mysql #sudo systemctl enable mysql
Step 5 – LAMP Stack MySQL Secure Configuration
Next to secure the MySQL installation, execute the following command in your terminal & Answer as follows:
#mysql_secure_installation
- Set root password? [y/n] y
- New password: Type in secure password for your database
- Re-enter new password: Retype the above password
- Remove anonymous users? [Y/n] y or Press Enter
- Disallow root login remotely? [Y/n] y or Press Enter
- Remove test database and access to it? [y/n] y or Press Enter
- Reload privilege tables now? [Y/n] y or Press Enter

Step 6 – LAMP Stack PHP Installation
Next, to install PHP execute below command in your terminal. Currently PHP 7.4 is the latest release, however if using CentOS default repos it shall install version 5.4.16. You can view our guide to upgrade to latest version of PHP here on our blog post.
#yum install php php-mysql php-fpm
Press y when prompted. Once it is installed, verify the PHP version as follows.
Next, php-fpm service is disabled & stopped bydefault, to enable & start the service perform below steps.
#systemctl enable php-fpm #systemctl start php-fpm #systemctl status php-fpm
Step 7 – Test PHP Integration with HTTPD
To test that php is serving contect via apache2 server, for this pupose we shall create php script in web root directory (/var/www/html/info.php) by entering “vim /var/www/html/info.php” in our terminal and pasting below code & save the file.
<?php phpinfo (); ?>
Now if you visit your server IP address/info.php, you will get below screen. which shows that PHP has been installed properly along with apache2 web server.
