Nagios Support Forum

*** Edited Subject

In my "Disaster Recovery" environment, I do not have internet access for the CentOS Linux release 7.6.1810 (x86_64) server on which I'm installing a licensed copy of Nagios XI. I downloaded the offline installer, as described in https://assets.nagios.com/downloads/nag ... onment.pdf. It appears to still require internet access to https://repo.nagios.com/, per my tests last week with the nagiosxi-5.6.3-2.el7.x86_64.tar.gz package. We do have internal software repos for the CentOS packages.

I'm not sure why the https://repo.nagios.com repo requirement exists in a "self-contained" installer. Any suggestions? Thanks in advance.

I'm confused where you saw the requirement for access to https://repo.nagios.com ?

Where did you see this?

Hi Scott! Thanks for the quick reply.

I apologize, this post description is now inaccurate; I had our team rebuild the box, and now the installer works better, for reasons that are opaque to me.

The issue I have now is that our users/groups are defined in NIS, where the "nagios" user and group is defined, so I will need to enable the installer to proceed past the "2-usersgroups" and possibly others like the sudoers step.

*********************
Running './2-usersgroups'...
Adding users and groups...
useradd: user 'nagios' already exists
groupadd: group 'nagios' already exists
groupadd: group 'nagcmd' already exists
ERROR: User 'nagios' was not created - exiting.
RESULT=1

INSTALLATION ERROR!
===================
Installation step failed - exiting.
Check for error messages in the install log (install.log).

If you require assistance in resolving the issue, please include install.log
in your communications with Nagios XI technical support.

Side note, I had to look very carefully thru the output to find this error, the installer exited with output that suggested success:

*********************
Updated:
nmap.x86_64 2:6.47-1

Complete!

(I didn't check exit status, my bad.)

Please do this:

Download this file to your /tmp directory of your XI server:
Then as root, run these commands:

Then send us the full output of all the commands and any errors if it fails again.

Thank you!

Excellent instructions, thank you! This workflow appears successful, tons of output after running rpminstall, but at the end Nagios is running, and I can login via the UI with the default account.

(Note, replace in instructions: "rpm2cpio nagiosxi-5.6.3-2.el7.x86_64.tar.xz" with "rpm2cpio nagiosxi-5.6.3-2.el7.x86_64.rpm")

Thank you very much for your assistance! Was there anything special about this tarball, or can we replicate this workflow going forward with future "offline" packages?

Updated, good catch!

Use that workflow going forward.

Additionally, you could do the same thing on upgrade if you have issues:
