EasyApache 4 in cPanel with CloudLinux: The Complete Step-by-Step Guide

EasyApache 4 is the part of cPanel & WHM that decides which Apache modules and PHP versions a server runs. CloudLinux is an operating system built for shared hosting that isolates each account and adds its own PHP tools. This guide is for administrators of a cPanel server: it explains how the two fit together and how to change them safely. If you have a shared hosting account, you don't need EasyApache at all; section 2 shows what to use instead.

1. Who this guide is for

Domain India VPS plans don't include cPanel, and the VPS page states that cPanel isn't offered on VPS. The server-admin sections below apply to a cPanel server you manage yourself.

2. On Domain India shared hosting: MultiPHP instead

Our shared cPanel servers already run CloudLinux 8 with CageFS, and the server's EasyApache profile is managed by us. You control your own site's PHP from cPanel:

• PHP version per domain: cPanel, Software › MultiPHP Manager. Measured in September 2026, our cPanel servers offer PHP 5.1 to 8.5, and new accounts start on 8.3. Full steps: how to change PHP versions with MultiPHP Manager.
• PHP settings such as memory_limit and upload size: the MultiPHP INI Editor or a .user.ini file. A php_value line in .htaccess causes a 500 error on our servers, because PHP doesn't run as an Apache module. See PHP memory errors and custom php.ini.
• Node.js and Python apps: cPanel's Setup Node.js App and Setup Python App, which come from CloudLinux.
• Disabled functions: some PHP functions are disabled on shared hosting whatever version you pick. See PHP disabled functions on shared hosting.

If you need a PHP extension or Apache module that your account doesn't have, open a ticket; you can't add server modules yourself.

3. EasyApache 4 in brief

EasyApache 4 installs Apache and PHP as ordinary system packages, named ea-apache24-* and ea-phpXX-*. Its WHM interface groups them into profiles: a saved list of packages that you can review and apply in one step.

Key ideas:

• Several PHP versions side by side. Each installed version (for example ea-php83 and ea-php84) can be assigned per domain in MultiPHP Manager.
• PHP handlers. PHP-FPM is the usual choice for performance and per-user isolation. CloudLinux adds mod_lsapi, a fast handler that works well with CloudLinux's limits.
• Apache MPM. With PHP-FPM or lsapi, the event MPM is the normal choice. The prefork MPM is only needed for old setups that run PHP inside Apache.
• Updates. Once installed, the packages update with the rest of the system.

4. Before you change a profile

5. Change a profile in WHM

From the command line, you can apply a saved profile the same way:

/usr/local/bin/ea_install_profile --install /root/ea4-new.json

Afterwards, set per-domain versions in WHM's MultiPHP Manager and enable PHP-FPM where you want it.

6. Adding CloudLinux to a cPanel server

CloudLinux replaces a compatible RHEL-family system, such as AlmaLinux or Rocky Linux, and needs its own licence. The vendor provides a conversion script. Follow their current instructions for your version, and reboot into the CloudLinux kernel when they tell you to.

What CloudLinux adds on a cPanel server:

Useful checks after conversion:

cat /etc/redhat-release          # should name CloudLinux
cagefsctl --list-enabled          # users inside CageFS
lvectl list                       # current LVE limits

7. MultiPHP or the CloudLinux PHP Selector?

Both let a user choose a PHP version, but they work differently. MultiPHP uses the EasyApache ea-php packages and is managed per domain. The CloudLinux PHP Selector uses CloudLinux's alt-php packages, is managed per account inside CageFS, and lets users switch extensions themselves.

They can conflict: a domain set to a specific version in MultiPHP Manager ignores the Selector. Pick one approach for your server and document it for your users. The CloudLinux documentation explains which handler and default-version settings the Selector needs.

8. Troubleshooting

• A site shows a 500 or 503 after provisioning: check that the domain's PHP version still exists and that required extensions are installed for that version. Look in the domain's error log and the Apache error log.
• Provisioning fails: read the output on the Review page, remove conflicting packages, and retry. You can restore the saved profile from step 4.
• Users hit resource limits: review the LVE limits in the CloudLinux section of WHM before raising server hardware.

9. Where Domain India fits

If you don't want to manage EasyApache, CloudLinux and licences yourself, shared cPanel hosting gives you a managed server where you only choose your PHP version. Prices on the card are live and exclude 18% GST.

If you need root access to your own server, a Domain India VPS is self-managed and comes without cPanel.
