Maintenance Downtime Tonight 18.04.2013

[Matt]

I'm going to be breaking Apache on the server in an hour or 2.

I'm trying to upgrade to Apache 2.4, but there are some issues, and I need to get some information while we are running 2.4, so I need to install it, get the information, and roll back to Apache 2.2

The site will be broken and not working during this time.

 

[Matt]

All done, got the information I needed for the support ticket.

 

[evocarlos]

its not broken

 

[Matt]

its not broken

I closed the board, but got what I needed pretty quick. There is an issue when I upgrade to Apache 2.4 with it not working correctly with various PHP applications, throwing errors relating to PCRE and the preg_match() function

preg_match(): Compilation failed: unknown option bit(s) set at offset -1
 
XenForo_Application::handlePhpError()

I've got a thread open on the cPanel support forum to see if they can help fix it.

 

[evocarlos]

that lot is like hieroglyphics to me lol
i'm sure a solution will make itself present soon

 

[Matt]

Had another hour trying to trouble shoot with this the people from cPanel, and it's still not working, so back to normal again on 2.2

 

[MikeS]

is it a php app on the forum index ?

 

[Matt]

is it a php app on the forum index ?

No, basically, I was trying to upgrade Apache to 2.4

This works, but it's not working correctly with the PCRE (Perl Compatible Regular Expressions) module. It's installed on the server, and works fine with Apache 2.2 When I update to 2.4, it's like it's linking to a different version.

We are currently running CentOS 5.9 as the server OS, so if I was to try this again (which I probably won't until 2.2 is EOL), I'd have the OS reloaded to CentOS 6.4 (or the latest 6.X release)

 

[MikeS]

still using 2.2?

 

[Matt]

Yeah, back on 2.2 now
