I'm not able to install new network analyzer.

Getting below error.

[root@ip-10-144-1-90 nagiosna]# ./fullinstall
ERROR: unable to read system id.
It looks like Nagios Network Analyzer is already installed.
[root@ip-10-144-1-90 nagiosna]# rhn_check -v
ERROR: unable to read system id.


After this i uncommented the below lines from /tmp/nagiosna/libinstall.sh

# If the system is Red Hat, make sure it's registered & has the appropriate
# channels enabled.
#valid_rhel() {
# if [ -x /usr/sbin/rhn_check ] && ! /usr/sbin/rhn_check 2>/dev/null; then
# if [ -x /usr/bin/subscription-manager ] && [[ ! -z $(subscription-manager list | grep Status: | grep -qF Subscribed) ]]; then
# error "your Red Hat installation is not registered or does" \
# "not have proper entitlements. Please register or" \
# "enable entitlements at rhn.redhat.com."
# fi
# fi
#}

#valid_rhel

After this i got below error.

[root@ip-10-144-1-90 nagiosna]# ./fullinstall

Need assistance on urgent basis

Please note that this server is not registered, we need a work around for this so that we could go ahead with the installation.

Is this a brand new install of Nagios Network Analyzer or you had a previous version already installed on this machine?

The system needs to be registered to RedHat, so that you would have access to all required repos. Technically, if you had access to all of the packages, you could comment out the section where it checks if RHEL is registerd, and proceed with the NNA install.

Have you installed any of the prerequisites manually? Do you have any local repos set up?

The server has access to internet, below are the list of yum repo

This error is displayed and the fullinstall exists if the following directory exists There is no reason this directory should ever exist on a clean minimal install system before installing

I have created a partition with that name

[root@ip-10-144-1-90 ~]# df -lh

I can see the benefit of what you did, so this is how to get around it, open libinstall and find this section and comment out the exit 0 like so Then run fullinstall again

Thanks for the update, i was able to get pass that step.

Now i see a different error (backend), attaching the installation log

Running 'backend'...
chmod: cannot access ‘/usr/local/nagiosna/bin/rc.py’: No such file or directory

===================
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 Enterprises technical support.

The step that failed was: 'backend'


=========================================

Below is the listing for /usr/local/nagiosna/

[root@ip-10-144-1-90 nagiosna]# ls -l /usr/local/nagiosna/
total 20
drwxrwxr-x 7 nna nnacmd 4096 Mar 14 06:38 backend
drwxrwxr-x 2 nna nnacmd 16384 Feb 28 17:33 lost+found

This is quite bizarre and maybe it is somehow because of the mounted directories, but the contents of that backend folder is supposed to be copied, not the folder itself..

Lets do this At this point I am a little nervous of what other parts of the install may not have went as expected. This same install process has worked on thousands of systems without issue for many years.

it worked, installation done. You can lock the thread now
