I am tried to re-install nagiosxi the same day I installed it first time and I get the below error re-installing NagiosXI.

Running './B-installxi'...
Installing Nagios XI base files...
Creating product directory...
Adding password for user nagiosadmin
Reloading httpd: [ OK ]
Building latest perms binary...
Checking PostgresQL status...

ERROR: role "nagiosxi" already exists

ERROR: Nagios XI database was not setup properly - 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.

The script that failed was: './B-installxi'

below is the logfile output when it fails
It appears as though Ajaxterm is already configured, so we'll skip that step.
Subcomponent 'ajaxterm' installed OK
Subcomponents installed OK

Can you give a little more detail as to what wasn't working from the first time? If there's a part of the installation that didn't appear to work we can talk you through how to rerun that part of the installation.

Part of creating an Nagios XI install is starting with a clean System

http://assets.nagios.com/downloads/nagi ... stallation

Note: Nagios XI can only be installed to RHEL, CentOS, or Fedora Core Linux distributions. We highly recommend installing Nagios XI on a 32-bit distribution.

Important: Nagios Enterprises highly recommends and will only support installing Nagios XI on a newly installed, "clean" system. Attempting to install Nagios XI on a pre-existing system with other applications already installed can cause the Nagios XI installation process to fail, critical system components and settings (e.g. database servers) to be modified in a way that negatively affects other applications, and previously installed applications to be automatically upgraded or removed. While installing XI on a system with other applications is possible, it is not recommended due to the possible interactions and complexity of multiple components that are required for Nagios XI to function. If you choose to ignore these warnings, you do so at your own risk.

Internet access is required for installation and upgrades!

As mguthrie mentioned, if you are having a problem it would be much easier to diagnose the problem, otherwise I would recommend starting with a clean system and running ./fullinstall

Honestly, it would likely be better to start with a clean machien and install Nagios XI fresh..

I have no idea if this is complete but you can try running these commands to remove Nagios XI

Code: Select all

# Remove Nagios Core files
echo "Removing Nagios Core files..."
rm -rf /usr/local/nagios

# Remove Nagios XI files
echo "Removing Nagios XI files..."
rm -rf /usr/local/nagiosxi

# Remove NagiosQL files
echo "Removing NagiosQL files..."
rm -f /etc/nagiosql

# Remove MySQL databases
echo "Removing MySQL databases..."
mysql -u root -pnagiosxi -e "DROP DATABASE nagios"
mysql -u root -pnagiosxi -e "DROP DATABASE nagiosql"
service mysqld restart

# Remove Postgres databases
echo "Removing Postgres databases..."
psql -U nagiosxi nagiosxi -c "DROP DATABASE nagiosxi"
service pgsql restart

# Remove DB backup scripts
echo "Removing database backup scripts..."
rm -f /root/scripts/automysqlbackup
rm -f /root/scripts/autopostgresqlbackup

You must still be installing on the system where the previous Nagios XI instance resided. There are many pieces to the "Nagios Machine" thus why we support installations on a completely fresh Centos/Rhel installation. You can run into a lot of snags trying to re install over an old install.

It seems like you have a proxy issue. Please, read our wiki post on this topic:

http://support.nagios.com/wiki/index.ph ... th_Proxies

I would recommend following the instructions above for setting up your proxy, then repeating the steps, outlined by scottwilkerson, and running the following commands:

Code: Select all

cd /tmp/nagiosxi
./fullinstall

Note: Do not run the install scripts individually! Please, run "fullinstall" instead.

First I tried running fullinstall script and it failed at ./E-importnagiosql, so I am tring to run it manually.

I see it invokes few other scripts
/tmp/nagiosxi/nagiosxi/basedir/scripts/reconfigure_nagios.sh
/tmp/nagiosxi/nagiosxi/basedir/scripts/import_nagiosql.sh
/tmp/nagiosxi/nagiosxi/basedir/scripts/restart_nagios_with_export.sh
/tmp/nagiosxi/nagiosxi/basedir/scripts/export_nagiosql.sh

when i try to find the script its failing it is export_nagiosql.sh

root@:/tmp/nagiosxi/nagiosxi/basedir/scripts: > ./export_nagiosql.sh
