EasyApache 4 installing PHP 5
EDIT 2022-06-20: Cpanel completely removed support for PHP 5.6, so this method no longer works on AlmaLinux 8. If you need PHP 5.6, the best solution is to use CloudLinux, which provides support for older PHP versions. CloudLinux is a popular Linux distro used by many shared hosting providers as it allows for better security and isolates each website to its own virtual file system. You can find more information on cloudlinux at

https://www.cloudlinux.com/os-shared/

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

https://gist.githubusercontent.com/serverok/ba144b7f04f0602a369406d7d400c87d

To install, run following commands as root
```
cd /etc/cpanel/ea4/profiles/custom
curl -s https://gist.githubusercontent.com/serverok/ba144b7f04f0602a369406d7d400c87d/raw -o serverok-all-php.json
```
Or save content of gist https://gist.github.com/serverok/ba97370b3184b480e29cf22c89dc69c3 as serverok-all-php.json, then upload it at
```
WHM > EasyApache 4 > Upload a profile
```
Now login to WHM > EasyApache 4, you will see

Click on “Provision” to install older PHP versions.

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
```
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:

http://patches.kernelcare.com/

KernelCare update kernel using cronjob in /etc/cron.d/kcare-cron
```
[root@ok cron.d]# cat kcare-cron 
31 */4  * * * root /usr/bin/kcarectl -q --auto-update
[root@ok cron.d]# 
```

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
```
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
```
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
```
whmapi1 twofactorauth disable_policy
```
Or run
```
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
```
/usr/local/cpanel/bin/uapi --user=username TwoFactorAuth remove_user_configuration
```
