CentOS

The current updated version of the official httpd is: 2.2.21

The updated CentOS 5.4 httpd version is: 2.2.3-45

I understand that it is it being kept up-to-date with the official version.

[b]My question is[/b]: if the CentOS version is an equivalent of a more advanced httpd version, then what is the way to know the 'real' version?

Thanks!

[code]
rpm -q --changelog httpd
[/code]

Will show you a list of all the fixes that have been made. In general, only security fixes are backported from the mainline release to the Redhat version although sometimes enhancements are also made - usually if a particular customer is willing to pay for it!

Thanks Trevor.

So it actually means that the current httpd version in a CentOS installation can't be compared to a version number from the main tree.

I guess that this goes for other packages as well, such as MySQL and php...

Good to know.

Again, thanks!

Yes. The upstream explanation of [url=https://access.redhat.com/security/updates/backporting/?sc_cid=3093]backporting[/url] may help you understand.
