PHP errors in RedHat 9 / possible to downgrade cPanel?

[gisol]

Our new servers came with RedHat 9 installed. After installing cPanel 8.4.0, right from the start we had problems running PHP scripts, mainly due to the following error from the php binary:

Incorrectly built binary which accesses errno, h_errno or _res directly. Needs to be fixed.

We normally recompile PHP anyway to include additional options not configured by default, so we are able to get around this problem for PHP scripts run through Apache. However, it does not help any PHP scripts run through cPanel, such as custom skins or Horde webmail.

We got around that problem for a while by replacing /usr/local/cpanel/3rdparty/bin/php with the php we compiled from source. However, after someone upgraded cPanel to version 8.5.3, Horde stopped working, giving the followig error:

Fatal error: Call to undefined function: _() in /usr/local/cpanel/base/horde/config/registry.php on line 86

so we had to replace our compiled php with cPanel's original prebuilt binary again. Our php pages in the custom cPanel skin don't display properly, but at least Horde works.

Now we have some additional servers that also have RedHat 9, on which we've installed cPael 8.5.4 (R7). On these servers, Horde doesn't work using either the pre-built php or the custom php we compiled from source.

We need to get Horde running as quickly as possible for our users. Since we had fewer problems with 8.4.0, is it possible to downgrade to that release until cPanel comes out with a version compatible with RedHat 9?

run /scripts/fixheaders , as it looks like you need to update your glibc headers
run /scripts/rpmup
recompile php/apache (/scripts/easyapache)

Should be all set to go.

I'm afraid I wasn't clear enough in my original post. We don't have problems with users' PHP scripts run from Apache; we have problems with PHP scripts run by cpanel, which uses /usr/local/cpanel/3rdparty/bin/php.

We always recompile Apache + PHP after installing cPanel on a new server, because our users need additional PHP features which are not configured by default.

Now, back to the question at hand: can we downgrade cPanel back to version 8.4.0?

If you're running anything but stable, you can downgrade to stable, though that's usually not the best idea. If not, then I don't think there's any way you CAN downgrade unfortunately.

We had the same problem....

This fixed the issue for us, thanks to the guys from Cpanel support.
