The Importance of Enabling LAMP Server on CentOS
In today’s digital age, businesses and individuals alike are relying on websites to connect and engage with their customers and audience. As such, having a reliable web server is crucial to ensure seamless website performance and accessibility. One of the most popular web servers that businesses and developers use is the LAMP (Linux, Apache, MySQL, PHP) stack, which provides a powerful combination of server technologies that enable fast and efficient web hosting. In this article, we’ll show you how to enable LAMP server on CentOS, one of the most popular and reliable Linux distributions available.
What is LAMP Server?
LAMP is an open-source software stack that comprises four main components: Linux, Apache, MySQL, and PHP. Linux is the operating system that runs the server, while Apache serves as the web server software. MySQL is the database management system that stores and retrieves data for the website, and PHP is the server-side scripting language that handles dynamic website content. Together, these four components make up the LAMP stack, which is widely used to host websites and web applications.
Why Choose CentOS?
CentOS is a popular Linux distribution that is widely used for server hosting due to its high stability, reliability, and security. It is also open-source, which means developers can access its source code and make modifications according to their needs. CentOS also provides easy integration with other popular software stacks, including LAMP, making it an excellent choice for hosting web applications.

How to Enable LAMP Server on CentOS
Enabling LAMP server on CentOS is a straightforward process that can be completed in a few simple steps. Here’s how:
Step 1: Update the System Packages
Before installing any software, it’s recommended to update the system packages to ensure you have the latest security patches and bug fixes. To do this, run the following command:
sudo yum update
Step 2: Install Apache Web Server
The next step is to install the Apache web server. You can do this by running the following command:
sudo yum install httpd
Once installed, start the Apache web server by running:
sudo systemctl start httpd.service
You can verify that Apache is running by visiting your server’s IP address in a web browser. You should see the Apache default page if everything is working correctly.
Step 3: Install MySQL
The next component of the LAMP stack is MySQL, which is the database management system. You can install MySQL by running the following command:
sudo yum install mysql-server
Once installed, start the MySQL service by running:
sudo systemctl start mysqld.service
To secure your MySQL installation, run:
sudo mysql_secure_installation
This command will prompt you to set a root password, remove anonymous user accounts, disallow remote root login, and remove the test database.
Step 4: Install PHP
The final component of the LAMP stack is PHP. You can install PHP by running the following command:
sudo yum install php php-mysql
Once installed, restart the Apache web server to enable PHP by running:
sudo systemctl restart httpd.service
You can verify that PHP is working correctly by creating a PHP info file in the Apache document root directory (/var/www/html/) with the following content:
<?php phpinfo(); ?>
Save the file as info.php and then visit your server’s IP address followed by /info.php in a web browser. You should see a page with detailed information about your PHP installation if everything is working correctly.
Step 5: Test Your LAMP Installation
Finally, you can test your LAMP installation by creating a simple PHP script that connects to the MySQL database. Here’s an example:
<?php
// Connect to MySQL database
$conn = mysqli_connect("localhost", "username", "password", "database");
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
echo "Connected successfully";
?>
Save this file as test.php in the Apache document root directory (/var/www/html/) and then visit your server’s IP address followed by /test.php in a web browser. If everything is working correctly, you should see the message “Connected successfully”.
