Uninstalling NagioXI after the XI folder has been blown away

[JakeHatMacys]

So I did a bad thing, I was attempting to backup / restore one of our other servers to the other.

Basically we need to move off this Physical box, so I took a back up, then tried to restore it onto our VM Test box.

It error'd out during the restore with a MySQL password issue for some reason. And well when that happened the Nagiosxi folder is not longer present on the box at all.

Meaning I can't run the uninstall script, and after downloading it and putting it on the server it appears to reference a bunch of stuff that no longer exists. So the question is what's the best way to blow away my old Nagios install and reload it?

Could I "rm -rf" the directories??? Then do a full install? I thought I'd ask first before making things worse haha. (It appears Nagios's Core folder is still there)

Could I "rm -rf" the directories??? Then do a full install?

The fullinstall script may still fail if this is not a "clean" system. You may try running the relevant commands from the "uninstall_xi.sh" script manually in order to remove users/groups, init files, DBs, etc.
Then run the fullinstall script, move your xi backup (from the "old server") to the "new" XI server and restore from it.

What happens if you just try running the same version upgrade?

Code: Select all

cd /tmp/nagiosxi
./upgrade

Then you should be able to run the uninstall script.

cp: cannot create regular file `/usr/local/nagiosxi/var/': No such file or directory

So stepped through the un-install script. Then tried to ./fullinstall:

Can you log in mysql as root? Run the following command and show the output:

Code: Select all

echo 'show databases;' | mysql -t -u root -pnagiosxi nagios

Is there any chance that you start "clean" (run the installer on a new, clean system, minimal install)? It may take less time to do this vs troubleshooting each step along the way. The idea is to have a clean install of XI, where you can restore from a backup, correct?
