Apache2 Web Server failed to run. I have reinstalled OpenSuse 42.1 twice but both times the Apache2 Webserver doesn’t run.

sudo systemctl start apache2.service

Job for apache2.service failed. See “systemctl status apache2.service” and “journalctl -xn” for details.

sudo systemctl status apache2.service

I have ran zypper to update Apache2 and it successully updated.

Now if I run it again, it displays “Nothing to do.”

Did you change the configuration in some way?
It should start fine with the default one.

Does /var/log/apache2/error_log exist?
If yes, it might contain more information why apache failed to start.

Maybe try to stop AppArmor as a test. This can cause strange problems if the profiles are wrong or you have an unusual system setup.

systemctl stop apparmor

I have stopped apparmor and tried to restart apache but failed to restart.

peace:/home/kiran # systemctl stop apparmor
peace:/home/kiran # systemctl start apache2.service
Job for apache2.service failed. See “systemctl status apache2.service” and “journalctl -xn” for details.
peace:/home/kiran # systemctl enable apache2.service
peace:/home/kiran # systemctl start apache2.service
Job for apache2.service failed. See “systemctl status apache2.service” and “journalctl -xn” for details.

/var/log/apache2/error_log does not exist.

Immediately after attempting to start your Apache service, run the following immediately in a console to display the last 100 entries written to the journal

journalctl -n 100

Also, going over some basics…

  • Where did you install Apache from, from the OSS?
  • Did you configure a website, and if you did, did you use the YAST http server module? You’d have to install it using YAST or zypper as follows
zypper in yast2-http-server
  • Are you posting the entire “systemctl status apache2” - I find it strange that it would say it stopped without first saying it had started.

In any case, you might consider just force re-installing with the following

zypper in -f apache2

Followed by starting apache

systemctl start apache2

It’ll take awhile to start this first time, then you should be able to verify it started with

systemctl status apache2

I have reinstalled OpenSuse 42.1 for the third time and this time it is working fine. I did not select many Server Functions and restricted to
i. File Server
ii. Network Administration and
iii. Web and LAMP Server.

**It is great to see Apache2 server running on OpenSuse 42.1.
**
I have installed Kdesktop as default Desktop and selected Gnome Desktop as well but Gnome desktop just hangs and does not run.

Good to see your problem is resolved.
From what you posted since my post, it looked like you had nagios installed, which could possibly have caused problems. I would have recommended removing nagios, then re-installing apache again.

And then, I would have suggested that you install any of many modern nagios clones or the most recent version of Nagios from nagios.com (yes, it costs if you’re monitoring more than a few machines) instead of the original nagios.

I have reinstalled OpenSuse 42.1 for the fourth time. Apache2 Web server failed to start again. **I have followed above instructions and uninstalled 3 apps related to nagios. I was able to restart Apache2 web server. Thanks TSU.

**Great ! Apache2 web server is running again.
