How can i upgrade nagios core Version 4.1.1 to nagios core Version 4.2.1 ?

Posted: **Mon Sep 12, 2016 2:54 pm**

Pretty simple really, you'll want to back up your configs and then grab the latest source:

https://github.com/NagiosEnterprises/na ... master.zip

Unzip on your server, enter directory, and run:

Code: Select all

./configure
make
make install

with whatever options you might have passed when initially installing.

It may be a permission problem for those files / folder and not a space issue causing the errors.
Can you login as root, run the following and post the output?

Code: Select all

ls -l /usr/local/nagios/
ls -l /tmp
df -h
df -i

Thanks

The permissions for the spool folder isn't correct. To fix that, run this command as root on the Nagios server.

Code: Select all

chown -r nagios.nagios /usr/local/nagios/var/spool

Then, can you run the following and post the output?

Code: Select all

ll /usr/local/nagios/
chage -l nagios
grep nag /etc/passwd
grep nag /etc/group

The nagios user account is not in the nagios group.
Edit the /etc/group file
Change this line from

Code: Select all

nagios:x:500:apache

to

Code: Select all

nagios:x:500:apache,nagios

Save it out and see if that helps.
If it still fails, run this command to verify the nagios software will load. Post the output

Code: Select all

/usr/local/nagios/bin/nagios -vv /usr/local/nagios/etc/nagios.cfg
