Upgrading Nagios XI to Latest Version

Before you update your Nagios XI server be sure to create a good backup that could be used to recover if there are problems.  This article provides you a script that you can use to backup Nagios XI before an upgrade and shows how to perform the upgrade of Nagios.

Upgrade Backup Script for XI

It is IMPERATIVE that you backup your Nagios XI before you upgrade. You need an excellent backup that you can depend upon. In this example, we are using a script to stop all major services so the best backup can be achieved.

The script is using bzip2 to compress as it creates the best compression, just have to save space on your server. It assumes you have created a /bk partition (modify that if your backup location is different). It does not make sense to backup to the same disk as the disk could go bad. The script also uses a timestamp so that you can go back to a known good date as you will probably want several backups.

Note: Check the names of your databases and the passwords that you are using as they may not match the settings in the example.

#!/bin/bash

##### BackUp Of Nagios Before Upgrade #####

# Timestamp Backups

TIMESTAMP=$(date +%Y%m%d_%H%M);

echo $TIMESTAMP

service nagiosxi stop

service npcd stop

service ndo2db stop

service nagios stop

mkdir /bk/upgrade_$TIMESTAMP

tar cjf /bk/upgrade_$TIMESTAMP/nagios_$TIMESTAMP.tar.bz2 /usr/local/nagios

tar cjf /bk/upgrade_$TIMESTAMP/nagiosxi_$TIMESTAMP.tar.bz2 /usr/local/nagiosxi

pg_dump -U nagiosxi -c -F p nagiosxi | bzip2 -c > /bk/upgrade_$TIMESTAMP/pg_nagiosxi_$TIMESTAMP.sql.bz2

mysqldump -u root -pnagiosxi nagios | bzip2 -c > /bk/upgrade_$TIMESTAMP/my_nagios_$TIMESTAMP.sql.bz2

mysqldump -u root -pnagiosxi nagiosql | bzip2 -c > /bk/upgrade_$TIMESTAMP/my_nagiosql_$TIMESTAMP.sql.bz2

service nagios start

service ndo2db start

service npcd start

service nagiosxi start

Here is an example of the script running.

./upgrade.sh

20120209_1259

NPCD Stopped.

Stopping ndo2db: done.

Stopping nagios: .done.

tar: Removing leading `/' from member names

tar: Removing leading `/' from member names

Starting nagios: done.

Starting ndo2db: done.

NPCD started.

Review the size of the backup to make sure it worked.

Upgrade Nagios XI

Download the latest version of Nagios to the /tmp directory.

wget http://assets.nagios.com/downloads/nagiosxi/2011/xi-2011r2.1.tar.gz

tar zxvf xi-2011r2.1.tar.gz

cd nagiosxi/

./upgrade

That should have you up and running, and have a good backup. It would be a good idea to run the backup again so you have a backup of the current settings.
