by Thạch Phạm

When you install CyberPanel, by default, CyberPanel developers will install their default PHP version on the operating system which is PHP 7.1 version. Many users may confuse this PHP version with a custom PHP version to run the website, but the two versions are completely different.

To customize the PHP version for websites, you can refer to the instructions below (currently, CyberPanel has customized PHP up to version 7.4)

So how to change the default PHP version of CyberPanel, then in this article AZDIGI will guide you on how to change this default PHP version, you can see the steps below.

After SSH into the VPS, you can check the PHP version of the currently running VPS by using the command:

To determine the path of this PHP file, use the command:

AZDIGI Tutorial
which php  

So the path containing the PHP file is located at /usr/bin/php

Step 3: Change the PHP version

AZDIGI Tutorial
cp /usr/local/lsws/lsphp74/bin/lsphp  /usr/bin/php    

(74 is the new PHP version I want to upgrade, if you want to change 7.2 or 7.3 please replace it with 72 and 73).

When running the command, the system will ask if you want to overwrite the current PHP version, press Y to agree.
