Incorrect files permission error when applying config

Post by jmercier »

This is strange, when I apply a config in CCM on my new install I get this

The following configuration files have incorrect permissions:

/usr/local/nagios/etc/commands.cfg (OWNER=root, GROUP=root, PERMS=u---------)
/usr/local/nagios/etc/contactgroups.cfg (OWNER=root, GROUP=root, PERMS=u---------)
/usr/local/nagios/etc/contacts.cfg (OWNER=root, GROUP=root, PERMS=u---------)
/usr/local/nagios/etc/contacttemplates.cfg (OWNER=root, GROUP=root, PERMS=u---------)
/usr/local/nagios/etc/hostdependencies.cfg (OWNER=root, GROUP=root, PERMS=u---------)
/usr/local/nagios/etc/hostescalations.cfg (OWNER=root, GROUP=root, PERMS=u---------)
/usr/local/nagios/etc/hostextinfo.cfg (OWNER=root, GROUP=root, PERMS=u---------)
/usr/local/nagios/etc/hostgroups.cfg (OWNER=root, GROUP=root, PERMS=u---------)
/usr/local/nagios/etc/hosttemplates.cfg (OWNER=root, GROUP=root, PERMS=u---------)
/usr/local/nagios/etc/servicedependencies.cfg (OWNER=root, GROUP=root, PERMS=u---------)
/usr/local/nagios/etc/serviceescalations.cfg (OWNER=root, GROUP=root, PERMS=u---------)
/usr/local/nagios/etc/serviceextinfo.cfg (OWNER=root, GROUP=root, PERMS=u---------)
/usr/local/nagios/etc/servicegroups.cfg (OWNER=root, GROUP=root, PERMS=u---------)
/usr/local/nagios/etc/servicetemplates.cfg (OWNER=root, GROUP=root, PERMS=u---------)
/usr/local/nagios/etc/timeperiods.cfg (OWNER=root, GROUP=root, PERMS=u---------)

Each of these config files needs to be writable by the apache and nagios users. To fix this problem, follow these steps:

Login to your Nagios XI server via SSH as the root user
Execute the following commands:
/usr/local/nagiosxi/scripts/reset_config_perms.sh


BUT I already executed the script and all my permissions are OK, I rebooted the server and still the same problem.

Also, my Selinux IS disabled, the output of getenforce is Disabled.

I don't know what to do at this point, some help would be welcomed

thanks

Can you run:
ls -l /usr/local/nagios/etc/
And post your result.

Thank you!

What version of Nagios XI are you running?

And are you sure these are on the same server?

The first item is showing all the files owned by root and the second shows the correct permissions.

Was this installed recently?
What OS is it installed on?

Can you post your /etc/sudoers file so we can check it's settings?

Try to apply the configuration again and post the error message, if any.

Thanks all for your help. I just found out the proble.

Thing is I'm installing Nagios with Ansible and I had a task that re-created the user Nagios after the installation (by mistake)
