Could not open command file '/usr/local/nagios/var/rw/nagios

[danoreilly]

I've encountered this, apparently all-too-common, error. This is RHEL 6.6. However, after reading (and trying) about 10,000 articles on this, nothing has cleared up the problem. So, here is what I think the pertinent information is:

# grep nag /etc/group
nagios54380:apache
nagcmd54381:nagios,apache
nagiosadmin54382:

# ll -d /usr/local/nagios/var/rw

HELP!!!!!!!!!!!!!!!!!!

Stop nagios:

Code: Select all

service nagios stop

When nagios is stopped what is the output of:

Code: Select all

ll /usr/local/nagios/var/rw

When nagios is stopped the nagios.cmd should not exists. If it does, delete it and then start Nagios.

Another problem can be SELinux. Is it enabled?

Code: Select all

getenforce

If it is, set it to permissive:

Code: Select all

sed -i 's/SELINUX=enforcing/SELINUX=permissive/g' /etc/selinux/config
setenforce 0
