Hi,
I have running iRedmail server with very old version (0.6.2). I'm preparing to update to current version by installing quite new 0.9.2 and performing procedure http://www.iredmail.org/docs/migrate.to … erver.html

After install iRedMail in 0.9.2 version and after reboot I have problem with httpd service. Occurs error:

-- Unit httpd.service has begun starting up.

Is anyone who can help me ?

Re: 0.9.2 CentOS 7 apache problem

*) Any related log in Apache log file?
*) Do you have Nginx running?

Re: 0.9.2 CentOS 7 apache problem

Hi,
In /var/log/messages I can't see nothing new

Sep 16 20:04:05 test kernel: httpd[2930]: segfault at 7fef70d990b0 ip 00007fef70d990b0 sp 00007ffcca994ff8 error 14 in mod_systemd.so[7fef70da8000+2000]
Sep 16 20:04:05 test systemd: httpd.service: main process exited, code=killed, status=11/SEGV
Sep 16 20:04:05 test kill: kill: cannot find process ""
Sep 16 20:04:05 test systemd: httpd.service: control process exited, code=exited status=1
Sep 16 20:04:05 test systemd: Failed to start The Apache HTTP Server.
Sep 16 20:04:05 test systemd: Unit httpd.service entered failed state.

During installation process I choose Apache instead Nginx.
I did some tests with Nginx and as I remember awstat didn't install automatically.

Re: 0.9.2 CentOS 7 apache problem

Does Apache work if you disable module 'mod_systemd'?

Re: 0.9.2 CentOS 7 apache problem

Hi,
If I disable mod_systemd module, Apache crashes during launching mod_cgi.so.

Re: 0.9.2 CentOS 7 apache problem

In addition,
I performed some tests:
- CentOS 7
- iRedMail 0.9.2

During installation process I choose NGINX and I dont have access to https://<my domain>/cluebringer/
I think that there is an error in installator script.

Re: 0.9.2 CentOS 7 apache problem

I have no idea here, didn't experience this issue before.

Do you have SELinux enabled in /etc/selinuc/config?

Re: 0.9.2 CentOS 7 apache problem

Try to disable Apache module 'mod_systemd'.

Thank you for this, I have been bashing my head off the damn desk for a week trying to figure out why my server wasn't working. I reinstalled CentOS 7 Minimal Web Server and omitted AWStats from my iRedMail install and now it works perfectly!

FWIW: Disabling mod_systemd causes a domino effect as far as errors are concerned. I think the segfault indicating mod_systemd is caused by systemd *NOT* being able to start Apache do to some unknown issue (now known to be the AWStats configuration). The logs show no useful information. Thank you again gibor!
