Operating system CentOS 5.5 (32 bit) [running as a guest on VMware ESX host]
Nagios 2011r1


I am doing a manual install because I need a larger disk space, I have not been successful at increasing the disk size on an existing Linux VM.

error running script 1-prereqs [No package perl-CPAN available]

The output from the script is :
Installing prerequisites...
Loaded plugins: fastestmirror

Not sure where you're at on either of these, but I figure we'll start from the beginning.

Here's a doc on resizing a VM disk.

Here's our manual installation doc.

Can you verify that you are running the installer from the /tmp/nagiosxi directory and that you've run the 0-yum installer script?

(There is also a 'full_install' script now that will run through all of the steps for you if you want).

Thanks for the links.
It looks like the PDF on resizing the disk will solve my issues.

On the manual install process, I followed the procedures outlined in the instructions and whrn you run the second script "1-prereqs" the script fails and it does not install the perlCPAN module.

As I mentioned in my case resizing the disk was my main concern, but I am curious why the script fails,

Thanks

There actually is no perl-CPAN package on some of the systems we support, so it's there for compatibility with others but fails on those. There's a comment to this effect in the script source, but it could be more clear (and will be in a later version of the installer).
