How to Check the LAMP Stack Version

When managing multiple servers with varying operating systems and configurations, it can be challenging to identify the exact versions of your LAMP stack components. This guide provides a simple method to check the versions of Linux, Apache, MySQL, and PHP on your server.

Steps to Check the LAMP Version

1. Check the Linux Version

Run the following commands to determine your Linux distribution and version:

cat /etc/redhat-release
uname -a

Sample Output:

From the above, the Operating System is RHEL 6.1 (64-Bit).

2. Check the Apache Version

Run the command below to find the Apache version installed:.

httpd -v

Sample Output:

Here, the Apache version is 2.2.15.

3. Check the MySQL Version

Use the following command to check the installed MySQL version:

mysql -V

Sample Output:
