For cPanel & WHM 11.44
As Linux operating systems age, it becomes increasingly difficult for cPanel to provide the support and level of functionality that our customers expect.
If you choose not to update your operating system, you need to understand how cPanel handles legacy operating systems that have reached their End of Life (EOL) dates.
What is "End of Life" (EOL)?
For our purposes, End of Life describes the point at which cPanel, Inc. will no longer support a particular version of an operating system (OS).
How does cPanel determine an operating system's EOL?
cPanel will support a specified operating system for the lifetime of the OS, plus an additional six months.
What is an OS's "lifetime"?
The lifetime of the operating system is set by the OS's vendor. We define it as the period of time that the vendor will continue to provide patches, fixes, and other updates.
What happens when an OS reaches EOL?
An OS that reaches End of Life will continue to function. An existing cPanel & WHM installation on a system that reaches EOL will continue to function.
However, you will be unable to perform the following tasks on an operating system that has reached its EOL:
- Perform a fresh installation of cPanel & WHM. New installations are prevented after the OS reaches the end of its lifetime
- Upgrade to a newer version of cPanel & WHM. Upgrades are prevented after EOL.
- Obtain OS-specific fixes — security or otherwise — from cPanel. These fixes will not be available after EOL.
How long will cPanel & WHM support my chosen operating system?
|Operating System||cPanel End of Life Date|
|CentOS 5.x, Red Hat Enterprise Linux 5.x, CloudLinux 5.x||August 31, 2017|
|CentOS 6.x, Red Hat Enterprise Linux 6.x, CloudLinux 6.x||May 30, 2021|
When the EOL date arrives, we will remove the operating system from the table above.
In addition, we will notify you of operating system EOL dates as they approach. We will deliver notifications in cPanel & WHM through normal update procedures, and through product documentation that is available on the cPanel website.
What should I do if my OS has reached, or will soon reach, its EOL date?
We recommend that you schedule an appropriate time to update the OS of your cPanel server.
The OS update procedure will depend on your OS and operating environment. In some circumstances, an update to the base OS may be available through the OS vendor. In other cases, you may need to provision another cPanel server, migrate the accounts onto the new server, and transfer the license.
cPanel will attempt to provide suggestions with the EOL notifications. For more specific information, contact your technical support provider. If you are unsure who to contact, read Where should I go for support?
If you run the fictitious operating system cPLinux version 3 on your server, the course of events might be similar to the following as it reaches EOL:
- Its vendor sets November 1, 2010 as their official lifetime end date for cPLinux version 3.
- cPanel, Inc. sets our EOL date for cPLinux version 3 to May 1, 2011.
- This date is based on the vendor's lifetime end date for the operating system, plus 6 months.
- After we determine the EOL date for cPLinux version 3, we update our information.
- You receive notification from cPanel when the EOL date is set.
- cPanel & WHM changes to enforce the EOL policy as follows:
- cPanel will not install on cPLinux version 3 — November 1, 2010
- cPanel will no longer update on cPLinux version 3 — May 1, 2011
- cPanel will not provide any fixes for cPLinux version 3 — May 1, 2011
