Hi,
I'm trying to configure Nagios according to the [url=http://wiki.centos.org/HowTos/Nagios]HowTos->Nagios[/url]
But [i]stalled[/i] at the [b]Setting up nagios.cfg[/b] step. :-(
Because there is NO [b]localhost.cfg[/b] in /etc/nagios.
[code]# ls /etc/nagios/
cgi.cfg command-plugins.cfg htpasswd.users nagios.cfg objects resource.cfg [/code]
Here is rpm -qa
[code]# rpm -qa nagios\* | sort
nagios-3.2.1-3.el5.rf
nagios-devel-3.2.1-3.el5.rf
nagios-plugins-1.4.14-1.el5.rf
nagios-plugins-nrpe-2.12-1.el5.rf[/code]
Looks like the versions have been upgraded!

have you tried looking in the /etc/nagios/objects directory?

Hi,Thanks,

I've just see the directory now.Meanwhile you already point out that.
[code]# ls /etc/nagios/objects/
commands.cfg localhost.cfg switch.cfg timeperiods.cfg
contacts.cfg printer.cfg templates.cfg windows.cfg[/code]
Should I mv that as *instructed* in the Wiki Page and proceed with the rest of the process ?

Actually I want to monitor a Local FTP service with Nagios.

The best bet is to go directly to Max Hetrick's guide. Hrrm, site seems to be down.

At the bottom of the page is a link to the original article--there were disagreements about the format of the wiki article, which unfortunately, led to its being less clear than it could have been, i.e., more like typical Linux documentation. :)

I suspect the maxsworld.org site will be back shortly, the link is at the end of the wiki article.

Hrrm, /etc/nagios/objects seems like something new. It used to all be in /etc/nagios.

Don't know when that change was made. Was that a nagios decision? Was there any point to it besides making it necessary to alter configuration files and keep people on their toes?

On my test machine(a.k.a. virtualmachine) that time had forgotten, it has

[code]
rpm -q nagios
nagios-3.0.6-1.el5.rf
[/code]

And the /etc/nagios/objects existed in that version. I do remember in my vague recollection that I did not moved any files or directories. All I did was install the package, configure the existing files, and test if it works as I expect it.

Ah, that explains it. Using nagios 2.x here.

I'm reading it as rest of the Wiki steps is fine to follow (?)

Able to start Nagios with "setenforce 0"
Cause,
[code]# chcon -R httpd_sys_content_t /var/nagios/
chcon: invalid context: httpd_sys_content_t[/code]
?

=========
EDIT:
=========
This one changed/accepted the contexts
[code]chcon -R system_u:object_r:httpd_sys_content_t /var/nagios/[/code]

With "setenforce 1"
[code]# restorecon -R /var/nagios/
# service nagios restart
Stopping nagios: [FAILED]
Starting nagios: [FAILED][/code]

I just heard from the article's original author (and creator of the page to which I linked, then said it seemed to be down.)

As he's quite busy these days, he doesn't know if the page will get back up, or be updated--as we've discovered here, the wiki article (and page to which I linked) are for nagios 2.

Phil, if you have a chance, maybe that last line in the wiki article, with a link to a no longer exisiting page, should be removed.

(And perhaps also a note about the article being for nagios 2.)
