II. How to change the default PHP version on FASTPANEL
To change the default PHP version on a system using FASTPANEL, we follow these 3 steps.
Step 1: SSH into your CentOS 7 system
To change the default PHP version, first, we need to SSH or access your VPS or server as root. If you do not know how to SSH into your VPS/Server, you can refer to the following tutorial:
After successfully SSH, we continue with step 2 to check the default PHP version being configured.
Step 2: Check the PHP version being configured
To check the PHP version being configured, we use the following command:
Below is the result of my VPS:
As you can see, the default PHP version when using the
php command on the system is
5.4.16. This is an extremely low version compared to the current PHP latest version is
When the default PHP version is so low, you will have many problems if you need to execute PHP source code that requires a higher PHP version or simply cannot use WP-CLI because WordPress requires a PHP version of at least
5.6.20 is required to run.
So how to change the default PHP version to 7.4, please follow step 3.
Step 3: Change the default PHP version to a higher PHP version
In case you have installed other PHP versions on the FASTPANEL interface and you have not installed them, please refer to the following instructions to install other versions:
After you have the desired PHP version, use the following command to view the execution paths of the PHP versions:
Here is my result.
Because I only installed 1 more PHP version, 7.4, there is only 1 path
/opt/php74/bin/php, if you install many other PHP versions, you will see more results.
Next, execute the following commands to replace the default PHP version with PHP 7.4.
rm /usr/bin/php ln -s /opt/php74/bin/php /usr/bin/php php -v
Explanation of the above commands:
- Command 1: Disable
phpcommand execution with the old PHP version. Choose
- Command 2: Associate the
phpcommand with the new PHP version path.
- Command 3: Check the default PHP version just linked.
Here is a process of change my default PHP version:
The commands may be slightly different if you have different versions of PHP installed.
So we are done with the operation to change the default PHP version when using the FASTPANEL installation system.
