Hello,

I was trying to install the NAgios on RHEL 4.0 and the steps I followed refrred to http://nagios.sourceforge.net/docs/3...rt-fedora.html and I did all the steps except [make install-webconf].Anyway I installed all the other steps from this link.Restarted apache and nagios without any issue.But now when I open http://localhost/nagios its not working.the log file:

I had this problem one time and it was a permissions issue with nagios writing to the cmd file. Can you check your systems logs to see if there is anything in there? Also look at the permissions of the directory that the cmd file is in.

Any reason you didn't install from RPM? If you are installing Nagios on an RPM based system, you really should use the RPM... Unless you need to configure something out of the norm.

Also if you are installing this on a Production machine, to montior Production machines; I'd suggest using 2.10 instead of going to the 3.0 branch which is still in Beta.

Edit:
Well - I guess you didn't use the RPM because you were following that link.

You should use the RPM which can be downloaded from the nagios Web site.

I remember that when I ran these commands:
make install
make install-init
make install-config

It ran without any issue.But the last one :
make install-commandmode <-------------
dint worked at all.

I saw the directory and there is nothing called rw in the directory;

usr/local/nagios/var/rw/nagios.cmd
Any Hint???

Din't worked.What I think is this may be the issue?
Also, the command [make install-webconf] dint work.

Pls Help??

There should be a directory, /usr/local/nagios/var/rw. If You don't have an rw directory, then make one! Then touch the file nagios.cmd within that directory, and change the ownership recursively of the rw directory to be owned by the nagios user and group.

Peace,
JimBass

Nagios Browser Not working????
 

I tried to make rw directory and nagios.cmd and restart the service..now Happily it shows no error during the nagios startup which it was showing missing earlier.

Things look okay - No serious problems were detected during the pre-flight check

So you are still getting the issue with no nagios.cmd in the rw folder?

Run ls -l on /usr/local/nagios/var

Make sure your nagios user owns all the files

When you go to http://localhost/nagios/ - Do you get a page cannot be displayed? Or Do you see a 'Whoops...'?

Nagios should be able to create a nagios.cmd, but it might not have the right permissions to do that.

Its still not working.I provided :
#chown -R nagios:nagios /usr/local/nagios/var/*
And tried to run :
#htmlview http://localhost/nagios
It says that :
--------------------------------------------------------------------
The requested URL /nagios directory was not found in this server
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
Apache/2.0.52 (Red Hat) Server at Localhost port 80
--------------------------------------------------------------------

You'll need to run a chown -R nagios.nagios /usr/local/nagios

Are you sure the web part of nagios is configured correctly? Seems like that isn't configured correctly.

You should have a file in /etc/httpd/conf.d/ called nagios.conf - OR you need add the Nagios stuff to the http.conf

By default, you should have apache looking in the conf.d folder for more conf's. You can check this by:

cat /etc/httpd/conf/httpd.conf | grep conf.d
You should get back this line:
Include conf.d/*.conf

Make sure it isn't commented out.

This is the default of what nagios entry for apache (you might need to change this for your needs)

If you didn't have a nagios.conf or didn't have the nagios stuff in your httpd.conf, and you just added it. You will need to restart Apache.
