Nagios, webmin and apache2

tc flag
Alex Tovey

I'm trying to configure nagios on webmin. I've ran through the tutorial but its still not working by that i mean when i goto web1.example.com/nagios is shows nothing, there doesn't seem to be a link to the /usr/local/nagios/share folder. I was thinking it's maybe needs a virtual host file setup but when i add the virtual host is says on restarting apache2.service

Oct 27 11:22:36 nagios.monster-it.uk apachectl[24761]: (2)No such file or directory: AH02291: Cannot access directory '/var/log/httpd/' for error log of vhost defined at /etc/apache2/sites-enabled/nagios.conf:1 Oct 27 11:22:36 nagios.monster-it.uk apachectl[24761]: AH00014: Configuration check failed Oct 27 11:22:36 nagios.monster-it.uk apachectl[24761]: Action 'graceful' failed. Oct 27 11:22:36 nagios.monster-it.uk apachectl[24761]: The Apache error log may have more information.

. It's given a template conf file for Apache but I need to make a virtualhost file but not sure how to go about it.

Welcome to AskUbuntu! Could you elaborate on "Not working"? What do you mean by this? Does the server return any data or are you getting a 500 error? Have you checked the logs in `/var/log/apache2` to see whether there is a message describing a configuration error or permissions issue?

I'm getting this in the error log. [Wed Oct 26 09:31:36.651146 2022] [mpm_event:notice] [pid 1889:tid 140477850631104] AH00493: SIGUSR1 received. Doing graceful restart 'AH00558: apache2: Could not reliably determine the server's fully qualified domain name, using nagios.monster-it.uk. Set the 'ServerName' directive globally to suppress this message'

That's just a notice, not an error. You would have likely seen something similar when issuing a `sudo service apache2 restart`. Could you explain what you mean by "not working", though? When it comes to websites, this can be interpreted 100 different ways ...

Okay, I've cleared the log fault with apache, but not when I visit the site with /nagios it comes up with 404 not found.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
