How to Install or Uninstall EasyApache 4

Last modified: March 7, 2023

Overview

This document describes how to install or uninstall EasyApache 4 on your server. You can migrate your server from EasyApache 3 to EasyApache 4 or install it manually.

You can migrate to EasyApache 4 with one of the following methods:

Use the EasyApache 4 Migration Tool in WHM’s EasyApache 3 interface (WHM » Home » Software » EasyApache 3).
Use the /usr/local/cpanel/scripts/migrate_ea3_to_ea4 script on the command line.

For more information about the migration process, read our EasyApache 3 to EasyApache 4 Migration Process documentation.

Important:

We deprecated EasyApache 3 on December 31, 2018. To migrate to EasyApache 4, click EasyApache 4 Migration Tool at the top of the EasyApache 3 interface (WHM » Home » Software » EasyApache 3). If you do not upgrade to EasyApache 4, you cannot upgrade to cPanel & WHM version 78.
You cannot migrate to or revert from EasyApache 4 on a system that runs cPanel & WHM version 78 or later.
You can only migrate a system that runs Tomcat in cPanel & WHM version 76 or above. For more information, read our Introduction to Tomcat documentation.
This section of the interface only exists in cPanel & WHM version 60 or later. In cPanel & WHM version 70 through 76, you must use the EasyApache 4 migration script if you wish to revert.
In cPanel & WHM versions 60 through 66, this section of the interface will not appear unless you select either the EDGE or CURRENT tier in WHM’s Update Preferences interface (WHM » Home » Server Configuration » Update Preferences). If you wish to migrate from EasyApache 3 to EasyApache 4 and you select either the RELEASE or STABLE tiers, you must use the EasyApache 4 migration script.

Requirements

Operating systems

EasyApache 4 supports all of cPanel & WHM’s supported operating systems.

Settings

You must activate the RPMUP setting if you install EasyApache 4 on your system. The system enables this setting by default. To do this, perform one of the following steps:

Open the /etc/cpupdate.conf file and set the RPMUP key’s value to daily. For more information, read our cPanel & WHM Update Configuration File - cpupdate.conf documentation.
In WHM’sUpdate Preferences interface (WHM » Home » Server Configuration » Update Preferences), set the Operating System Package Updates setting to Automatic.

Apache and PHP

EasyApache 4 only supports Apache version 2.4.

The cPanel default profile includes PHP versions 8.0, 8.1, and 8.2.

EasyApache 4 supports PHP versions 5.4 through 5.6, PHP versions 7.0 through 7.4, and PHP 8.0 through 8.2.

Note:

EasyApache adheres to the php.net supported versions timeline. The profiles that we supply in WHM’s EasyApache 4 interface (WHM » Home » Software » EasyApache 4) only provide PHP versions that php.net currently supports.

RPMs for unsupported versions of PHP will remain on the cPanel, L.L.C. mirrors and servers, but we will not provide any further updates.

Important:

Each time that you perform a migration from EasyApache 3 to EasyApache 4, the system moves the /usr/local/apache/ directory to the /usr/local/apache.ea3/ directory.
- If the /usr/local/apache.ea3 directory exists, the system moves the /usr/local/apache/ directory to the /usr/local/apache.ea3.1/ directory.
- If the /usr/local/apache.ea3.1 directory exists when you run a migration, the migration will fail in order to prevent loss of data.
The chance of errors dramatically increases if you migrate your system multiple times. If you revert several times, you must manually delete the previous /usr/local/apache.ea3.1/ backup directory to continue. The system automatically preserves the /usr/local/apache/ directory.

Migrate from EasyApache 3 to EasyApache 4

Versions 60 through 76

Warning:

EasyApache 3 blocks cPanel & WHM version 78 and higher. You must migrate to EasyApache 4 in cPanel & WHM version 76 or earlier.

To migrate your server from EasyApache 3 to EasyApache 4, perform the following steps:

Navigate to the EasyApache 3 interface (WHM » Home » Software » EasyApache).
Click EasyApache 4 Migration Tool.
Click Migrate. A confirmation message will appear.
To confirm that you wish to migrate, click Yes, run EasyApache 4 Migration. The system will start the EasyApache 4 migration and display the progress log. For more information about the migration process, read our EasyApache 3 to EasyApache 4 Migration Process documentation.
Click Done.

Note:

If your system runs CloudLinux™ and you experience difficulty with the conversion, you may need to run the CloudLinux conversion script to migrate your system.
If your system runs Tomcat, you must use cPanel & WHM version 76 to migrate to EasyApache 4.
If your system uses the FCGId Apache module, you must use cPanel & WHM version 76 to migrate to EasyApache 4.
If your system uses the FCGId Apache module and your system runs CloudLinux, you must disable the FastCGI option in EasyApache 3 before you start the migration.
On systems that do not run CloudLinux, if you receive a message that you must install the Experimental Repository, you must install the repository with the yum install ea4-experimental command, then attempt to migrate the server again.

Versions 52 through 58

Servers that run cPanel & WHM versions 52 to 58 must use the EasyApache 4 migration script.

Revert to EasyApache 3 from EasyApache 4

Important:

You can only uninstall EasyApache 4 if you migrated your system from EasyApache 3.
You cannot revert to EasyApache 3 if your system runs cPanel & WHM version 78 or later.
This action reverts the system to your previous EasyApache 3 installation and configuration.
This action attempts to move the Apache files to a new location and revert the server to the previous state.

Versions 70 through 76

To revert your system to EasyApache 3 from EasyApache 4, you must use the EasyApache 4 migration script.

Versions 60 through 68

To revert your system to EasyApache 3 from EasyApache 4, perform the following steps:

Navigate to the EasyApache 3 interface (WHM » Home » Software » EasyApache 3).
Click Revert. A confirmation message will appear.
To confirm that you wish to revert, click Yes, run EasyApache 4 Revert. The system will start the EasyApache 4 reversion and display the progress log.
Click Done.

Versions 52 through 58

To revert your system to EasyApache 3 from EasyApache 4, you must use the EasyApache 4 migration script.

Migrate your system on the command line

Use the /usr/local/cpanel/scripts/migrate_ea3_to_ea4 script to install or uninstall EasyApache 4 on the command line.

Migrate to EasyApache 4

Log in to your server via SSH.
Run the following command as the root user:
```
/usr/local/cpanel/scripts/migrate_ea3_to_ea4 --run
```
Note:
- If your system runs CloudLinux™, the migrate_ea3_to_ea4 script downloads and runs CloudLinux’s EasyApache 4 migration script.
- If your system runs CloudLinux, you cannot use options (for example, the --install_profile option) with the EasyApache 4 migration script.
- If your system runs CloudLinux, you must disable the FastCGI option in EasyApache 3 before you run the migration script.
- As the migration script runs, the /scripts/migrate_ea3_to_ea4 script copies the /usr/local/lib/php.ini file to the /opt/cpanel/ea-php??/root/etc/php.d/php.ini file and to all installed ea-php versions on your server. To prevent complications, the system comments out lines that resemble the following lines:
  - extension=
  - extension_dir=
  - zend_extension-
- The system does not adjust any other lines.
- On systems that do not run CloudLinux, if you receive a message that you must install the Experimental Repository, you must install the repository with the yum install ea4-experimental command, then attempt to migrate the server again.
The interface displays the changes that will occur. To continue, follow the interface’s instructions.

Revert to EasyApache 3

Remember:

You can only uninstall EasyApache 4 if you migrated your system from EasyApache 3.

Run the following command as the root user:

/usr/local/cpanel/scripts/migrate_ea3_to_ea4 --revert --run

Follow the system’s instructions.

Arguments

The migrate_ea3_to_ea4 script accepts the following arguments:

--run — Required. Run the script.
--help — Display the help information.
--revert — Revert the system to the previous version and configuration.
--skip_convert — Do not convert and install the EasyApache 3 profile. This flag installs the EasyApache 4 cPanel Default Profile unless you use the --install_profile flag.
--install_profile — Do not convert the EasyApache 3 profile. Instead, install the specified profile. For example:
```
/usr/local/scripts/migrate_ea3_to_ea4 --run --install_profile /path/to/profile
```
--convert_fail — When you convert an EasyApache 3 profile to an EasyApache 4 profile, this flag prevents execution of the script’s error-correction code.

Warning:

This may cause a failure when you provision your system. However, you may wish to use this flag for tests.
--allow-unsafe-amount-of-tomcat-users — Migrate a system that possesses more than five Tomcat users.
Note:
- This flag only exists on systems that run cPanel & WHM version 76 or higher.
- Tomcat consumes a high amount of memory. Make certain that your system possesses enough memory before you perform this action.
--y — Answer yes to all of the script’s yes-or-no questions. This function also accepts the -y, --y, -yes, and --yes argument format.
--force — When you add this argument to the --run or --revert arguments, the system ignores the protection checks.

Warning:

This may cause a failure when you provision your system.
--reinstall — Yum attempts to install the required EasyApache 4 RPMs and attempts to reinstall any currently-installed EasyApache 4 packages.
