I have installed nagios following this guide: https://assets.nagios.com/downloads/nag ... 1532076035

I have also tried to uninstall it with script uninstall_xi.sh downloaded from here: https://support.nagios.com/forum/viewto ... f=6&t=7102
It shows:

Code: Select all

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

and when I run again ./fullinstall, it shows:

It looks like Nagios Network Analyzer is already installed.

We recommend installing on a fresh minimal install system.

Why not on the same system?

Why do I need to do a fresh minimal install system?

We do not have a script that clean up and removes all the databases, directories and packages from the original install. and you would be left with fragments of files, logs etc that would not be relevant to the current install causing confusion.

So basically, there is no way to uninstall it?

That is correct. You could remove the directories but there are other additions that will still be present

Code: Select all

rm -rf /usr/local/nagiosna
rm -rf /var/www/html/nagiosna

Okay.. I've done

Code: Select all

sudo rm -rf /usr/local/nagiosna
sudo rm -rf /var/www/html/nagiosna/

and

Code: Select all

sudo rm /etc/init.d/nagiosna

also delete extracted nagiosna folder

and follow installation guide again.
It is installed successfully !!

NOTE: mysql-server should be installed correctly with root password.
