Oracle Linux is really a substitute for CentOS, many novices are not very clear about this, in order to help you solve this problem, the following editor will explain for you in detail, people with this need can come to learn, I hope you can gain something.

Oracle recently announced that its Oracle Linux is a better free alternative to CentOS and provides a switching script. But is this really the case?

On Oracle's promotional page, Oracle strongly emphasizes the advantages of Oracle Linux:

Compared to RHEL,Oracle Linux, it provides free software updates.

Provide security updates faster than CentOS,Oracle Linux.

Employ professional engineers and QA team.

If you need to pay for support, the price is cheaper than RHEL.

Has Oracle decided to give back to Linux users? Wake up, honey, this is Oracle!

The developers of the CentOS community gave on their blog something that Oracle deliberately ignored on the promotional page: the 2012 security update schedule.

It is clear from the table that CentOS almost always got security updates earlier than Oracle Linux in mid-2012, which is also an improvement from the continuous update repository created by CentOS.

It is worth pointing out that if enterprise users really care about the timing of getting security updates, they should subscribe to RHEL's support services instead of Oracle's. Oracle Linux will never get security updates faster than RHEL.
