How did Nagios update on it's own? How can I get running?

Could it be that after the upgrade it is not looking in the correct location for the config files?

That is likely the case as the version installed via yum has the /usr/local/nagios/xxx directory structure.

It's not clear to me that this is actually the case, but maybe I missed something in the previous postings.

Can you do this:

Code: Select all

yum list | grep -i nagios

Ok so i ran that and the result is attached.

Thanks! Now we all know what version(s) we're dealing with!

And to be clear that is where it is right now after reverting to the previous VM snapshot.
I've added the exclude=nagios* into the main /etc/yum.conf file, if it doesn't update in the morning than i guess that fixes the auto-update issue if it does update again then i can grab the updated results and post again.

The main goal is to stop the auto-update for now, then I'll have to look at trying to upgrade and get it working in the future.

Do you have admin (root) privileges for this Nagios server? If so, as root run the following command:

Code: Select all

for user in $(cut -f1 -d: /etc/passwd); do crontab -u $user -l; done

Then for each user that has a crontab, run this command:

Code: Select all

crontab -u USERNAME -e

And post the results.

Please post the contents of /root/update.sh

Please post the contents of /root/update.sh

[root@wc-nagios ~]# cat /root/update.sh
date >> update.log
yum -y update >> update.log
yum -y upgrade >> update.log
shutdown -r now >> update.log

Mystery solved...

Change to:

Code: Select all

date >> update.log
yum -y -x 'nagios*' upgrade >> update.log
shutdown -r now >> update.log

Running yum update and yum upgrade is redundant as they do the same thing. The difference is that yum upgrade removes obsolete packages.
yum upgrade = yum update --obsoletes

Thanks bolson, Besides adding the exclusion for nagios* in the /etc/yum.conf file I've also made the changes mentioned above and as of this morning Nagios is still running 3.5.1 and working like a dream.
Once again thanks for all the help.

Now when time allows we'll see how the eventual planned upgrade goes.
