EasyApache 4 installing PHP 5
Cpanel have removed PHP 7.0 and older version from newer cpanel installations. Existing servers with older version of PHP will continue working.
https://blog.cpanel.com/removal-of-php-5-6-and-php-7-0-in-easyapache-profiles/
If you have a new cpanel server, but required older PHP version for some of your site to work, you can download EasyApache 4 profile from another server and upload to your server and provision it to get older PHP version.
I have EA4 profile with Older PHP version available at

KernelCare Unknown Kernel
On Cpanel server with KernelCare installed, i keep getting email
This is because the kernel is not yet supported by kernalcare. Since this kernal is provided by CloudLinux, you don’t have to worry. CloudLinux support said they do add support for KernelCare after 3 to 4 days of releasing new kernel.
To disable this warning, edit file
|
1 |
vi /etc/sysconfig/kcare/kcare.conf |
Add
|

IGNORE_UNKNOWN_KERNEL=True |
You can find more KernelCare options at
https://docs.kernelcare.com/config_options/
You can always check if KernelCare supports your current kernel here:

KernelCare update kernel using cronjob in /etc/cron.d/kcare-cron

Disable PHP disable_functions on Cpanel Server
On a Cpanel Server using CentOS 7 + php-fpm, site phpinfo() shows few functions are set to disabled in disable_functions.
I checked server wide PHP configuration in WHM for the PHP version the site is using. There is no disable_functions specified.

WHM > Software > MultiPHP INI Editor > Editor Mode > PHP 7.3 |
This is because in Cpanel server running in PHP-FPM, you need to edit php-fpm pool config file at
|
1 |
vi /opt/cpanel/ea-php73/root/etc/php-fpm.d/DOMAIN_NAME.conf |
Replace ea-php73 with whatever PHP version you selected for this web site.
Remove the line
|
1 |
php_admin_value[disable_functions] = exec,passthru,shell_exec,system |
Restart php-fpm with
|

/scripts/restartsrv_apache_php_fpm |

Disable 2 Factor Authentication in Cpanel
To disable 2 Factor Autentication for WHM in Cpanel Server, SSH into server as user root, run
|
1 |
whmapi1 twofactorauth disable_policy |
Or run
|
1 |
whmapi1 create_user_session user=root service=whostmgrd locale=en |
This will create a link for WHM login, using this link won’t require 2 Factor Authentication. After logging into WHM, you can disable 2 Factor Autentication.
If you want 2 FA disabled for a cpanel user, run
