PHP is a popular scripting language widely used for web development. If you’re using CentOS 6.2, you may need to install PHP to run dynamic websites and applications. In this guide, we will walk you through the steps to install PHP on CentOS 6.2.
Step 1: Update System Packages:
Before installing PHP, it’s a good practice to update the system packages to their latest versions. Open your terminal or SSH into your CentOS 6.2 server and run the following command:
sudo yum update
This command will update the package lists and upgrade the installed packages on your system.
Step 2: Install PHP and Required Packages:
To install PHP and its required packages, use the following command:
sudo yum install php php-cli php-common
This command will install PHP, the PHP command-line interface, and the common PHP modules on your CentOS 6.2 system.

Step 3: Verify PHP Installation:
Once the installation is complete, you can verify PHP installation by running the following command:
php -v
This command will display the PHP version and other related information if PHP is installed correctly.
Step 4: Configure PHP:
By default, PHP is configured with the basic settings, but you may need to modify the configuration based on your requirements. The PHP configuration file is located at /etc/php.ini. Open the file in a text editor and make the necessary changes.
For example, if you want to enable error reporting, find the following line:
; display_errors = Off
And change it to:
display_errors = On
Save the file after making the changes.
Step 5: Restart Web Server:
To apply the changes and make PHP available for web server processes, you need to restart the web server. On CentOS 6.2, the most commonly used web server is Apache. Restart Apache using the following command:
sudo service httpd restart
This command will restart the Apache web server, allowing it to recognize PHP and serve PHP-enabled web pages.
Commands Mentioned:
- sudo yum update – Updates system packages.
- sudo yum install php php-cli php-common – Installs PHP and its required packages.
- php -v – Verifies the PHP installation and displays the PHP version.
- sudo service httpd restart – Restarts the Apache web server.
Conclusion:
Congratulations! You have successfully installed PHP on CentOS 6.2. Now you can start developing dynamic websites and applications using PHP. Remember to regularly update PHP and its modules to ensure security and performance.
