I am trying to install Nagios 4 on an old Pentium 4 machine running Centos 7. I have installed the OS from the x86_64 ISO provided at the website. Nagios is downloaded with wget from Sourceforge. I have followed these instructions to the letter, but every time I seem to hit a wall at the same spot. First these commands refuse to execute:
chkconfig --add httpd
chkconfig --level 35 httpd on
And then this command does not complete:
systemctl start nagios.service
The message I receive says that it failed and the reason is "resources".
UPDATE:
I decided to go the "OMD" way as was suggested in one comment.
The package installed correctly from the EPEL repository. When I run omd start sitename
the output implies that everything works correctly.
When I try to view the GUI from Lynx (I have to use a command line browser for the time being) first it shows a 503 Error
and then something along the lines of "Site not started - You need to start the site to be able to launch the GUI"
. The only indication of something going wrong is some lines in the apache error_log that start with proxy:error
and http_proxy:error
.
