Proxmox recently discontinued 3.x, forcing me to migrate over to 4.x.

Long story short, after converting the OpenVZ cPanel VM to LXC and re-configuring it, I booted it and all of my sites returned error 500.

I looked at the apache logs and found errors like:
[Tue Apr 18 04:12:11.207619 2017] [cgid:error] [pid 5454:tid <tid>] [client <myip>:59504] End of script output before headers: redirect.cgi

This error is one of the remaining errors I have, when you try to go to domain/cpanel or domain/whm. I fixed the sites by checking:

/usr/local/cpanel/bin/rebuild_phpconf --current

which reported all (except the default) PHP were using suphp instead of cgi.
When I switched the default php to suphp, sites worked, but the redirection still does not.

I believe something happened that is blocking cgi. Any ideas?

Hello,

We do have an internal case open (EA-5010) related to "suexec" (/usr/sbin/suexec) using file capabilities to specify setuid/setgid permissions instead of the traditional file mode bits. Could you open a support ticket using the link in my signature and reference this case number so we can verify if your system is affected by this issue?

Thank you.

I am just re-rolling a new CentOS 7 VM in KVM instead of fighting with LXC. I believe AppArmor was an issue too as it was messing up named. However, I tried putting that lxc.aa_profile var in various config locations without success. Therefore I decided for the sake of fast repair, and to hopefully prevent issues in future Proxmox forced conversions/breakage, that a KVM would be better.

Thanks though.
