Reading Configuration File

[jcooper]

New server have only configured a few things.

When I log in as nagiosadmin I get the error 'Error: Could not read object configuration data!"

I've verified the configuration files and they seem legit.

It acts as though nagiosadmin doesn't have permission to view the config file. Where can I check this?

OS: Ubuntu 16.2
Nagios Core 4.3.1

Appreciate the help!

You can see file permissions by doing a:

Code: Select all

ls -la <file>

Nagios Core configuration usually starts with a file named nagios.cfg which references other configuration files.

Output:
root@server:~# la -la /usr/local/nagios/etc/nagios.cfg
-rw-rw-r-- 1 nagios nagios 44879 Apr 6 14:19 /usr/local/nagios/etc/nagios.cfg

Nagios admin doesn't show up as I believe it's due to it being set up as an apache2 user?

Any help is greatly appreciated!

is your apache user in the nagios group?

If you're trying to solve the

Error: Could not read object configuration data!

issue, then that likely stems from selinux. You can temporarily disable it by running:

Code: Select all

setenforce 0

However it's a little difficult to tell what you want an answer on because you cite the error then ask questions about something else. The log files /var/log/syslog and the apache error log may also provide some insight into your issue.

Apache user "www-data" was already a member of the Nagios group

When attempting to run command "setenforce 0" it tells me it's not installed.

I'm just looking for possible solutions to why nagiosadmin can't read the config file (Nagios.cfg). I've done the Nagios config file check and it checks out fine.

You may need to refer to your OS's documentation on how to disable selinux.

Can you provide the log files I referenced?

I've attached syslog and the apache error lines are below:

[Wed Apr 12 07:35:02.317235 2017] [mpm_prefork:notice] [pid 1391] AH00163: Apache/2.4.18 (Ubuntu) configured -- resuming normal operations
[Wed Apr 12 07:35:02.317295 2017] [core:notice] [pid 1391] AH00094: Command line: '/usr/sbin/apache2'

Appreciate the help!

how did you install? it's definitely permissions somewhere.

i would start fresh with the guides that the wizards at nagios wrote because they've worked every time for me. https://support.nagios.com/kb/article.p ... ategory=58

Can you login to the Nagios server as root, run the following and post the output?

Code: Select all

ls -lR /usr/local/nagios/etc
grep nag /etc/passwd
grep nag /etc/group
cat /usr/local/nagios/etc/cgi.cfg
