[edit] Check Installation chmod code doesn't match example

At the tail end of the Check Installation section: 

 It is suggested that permissions similar to this are applied:
 :drwxr-xr-x  2 nagios nagios 4096 Apr 10 06:35 /etc/nagios
 
 #chmod 711 /etc/nagios

To achieve the suggested permissions, the chmod line should be changed to 

 #chmod 755 /etc/nagios

-- client configuration for windows working on linux client installs.
-- cleaned useless info 
-- added information regarding cgi.cfg
-- some other stuff
-- cleaned talk page hard to read what needs to be done

[edit] Problems to be solved

Add new problems here as the old comments seemed stale so I removed them. stillbourne

This HOWTO configures nagios to write status information to the DB, while in /etc/nagios/cgi.cfg the nagios_check_command variable refers to the status.log file which does not exist when DB status is enabled.

/usr/nagios/libexec/check_nagios_db.pl should instead be used. It takes two parameters,

-c <path to cgi.cfg>
-e <expire time in minutes>
Code: /etc/nagios/cgi.cfg 
nagios_check_command=/usr/nagios/libexec/check_nagios_db.pl -c '/etc/nagios/cgi.cfg'

I had to tinker with ownerships so that apache could to execute the plugin. 

chown nagios:apache /usr/nagios/libexec/check_nagios_db.pl

This doc specifies that dependencies.cfg should be disabled in nagios.cfg - however the same applies for escalations.cfg (v1.4.1 at least)

[edit] Congrats

I run a pile of IDS and monitoring apps including Nagios and i thought i'd have a look here, just wanted to say great job. Even though I havent read through it all it looks great. --Ghettodev 11:44, 25 January 2006 (GMT)

[edit] Some Suggestions

  • I was running into Could not open password file: /usr/nagios/etc/htpasswd.users I had to chgrp apache /etc/nagios
  • CGI Troubleshooting tip - verify file permissions of object config files, if not all readable by apache, the cgi will fail silently with an error that can look like an authorization problem. Des09 18:34, 22 March 2006 (GMT)
  • I took quite a bit of notes, and got it up and running -- mind if I add/update the page further? --SeeBQ
  • I had to modify /etc/init.d/nagios so that it uses /var/run/nagios.pid instead of /var/nagios/nagios.lock. I had to modify both start() and stop(). I saw some chown and rm -f in there too. --Bering

[edit] Regarding Nagios core 2.10-r1

/etc/nagios/checkcommands.cfg /etc/nagios/misccommands.cfg

files need to be configured I think.

not able to start nagios until we configure above files

Edit: There are two nagios.cfg* file in the /usr/share/doc/nagios-core-2.10-r1/sample-configs/ directory. nagios.cfg-sample and nagios.cfg. The wiki article says in the "Setup configuration files" section that "rename .cfg-sample .cfg *.cfg-sample". This is not quite good, if you are using nagios2 because the nagios.cfg-sample file is for nagios-1, and this command overwrites the normal nagios.cfg which for nagios-2.10. I suggest to delete or skip the nagios.cfg-sample file in this situation. --Balage (02.18.2008)
