chown nagios:nagcmd /usr/local/nagios/var/rw/nagios.cmd

/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
systemctl restart nagios.service
cat /etc/redhat-release

Can you post the instructions you used when initially installing? It looks like the variables for permissions are getting set on start.

What are they getting set to after you start the service? (before running the chown)

Hi Robert,

cat /etc/init.d/nagios -> http://sprunge.us/dJSU. I am following http://tecadmin.net/install-nagios-core ... ntos-rhel/. Please correct me if i am doing wrong.

If you do restart the nagios daemon, what do the permissions change to?
Can you run the following and post the output?

Code: Select all

chage -l nagios
grep nag /etc/passwd
grep nag /etc/group

Also, can you show us the results of

Code: Select all

ls -ld /usr/local/nagios/var/rw

We want to make sure you have the group sticky bit on the directory and the group should be nagios

Code: Select all

drwxrwsr-x 2 nagios nagios 4096 Aug 16 05:59 /usr/local/nagios/var/rw

Additionally your nagios user should be a member of the nagios and nagcmd group

Code: Select all

# cat /etc/group|grep nag
nagios:x:500:nagios,apache
nagcmd:x:501:nagios,apache

When you compiled Core, did you run the configure command like below?

Code: Select all

./configure --with-command-group=nagcmd

Try and recompiling Core by following this guide and see if that fixes the issue.
