This page contains notes on using and administering Nagios and Fruity within the NST.
There are several possible ways to backup/restore the Nagios configuration. Being able to do so is useful for the following reasons:
- If you mis-configure your Nagios system, you can restore from your last good backup.
- You can create an initial backup to serve as a base template when setting up new systems.
- It makes using a Live CD much easier (save your configuration before stopping the system, then reload it the next time you boot).
Backup/Restore via Fruity
If you used the Fruity interface to manage your Nagios configuration, you should be able to do the following:
- Go to the NST WUI page for Nagios and export the Fruity database.
- Use the following steps to restore the configuration:
- Go to the NST WUI page for Nagios and import the Fruity database (the MySQL server must be started prior to doing this).
- Use Fruity interface to export the configuration from the Fruity database to Nagios.
- Start the nagios service.
Backup/Restore Without Fruity
If you did not use Fruity to configure Nagios, try the following to backup/restore your Nagios configuration (this has not been verified):
tar czf - -C /etc nagios >| nagios.tar.gz
ssh root@IP_ADDRESS tar czf - -C /etc nagios >| nagios.tar.gz
- Go to the NST WUI page for Nagios and setup Nagios with the minimal configuration.
- For a local restore, replace the minimal Nagios configuration with the backup copy using the following command:
cat nagios.tar.gz | tar xzf - -C /etc
- For a remote restore, replace the minimal Nagios configuration with the backup copy using the following command:
cat nagios.tar.gz | ssh root@IP_ADDRESS tar xzf - -C /etc
- Finally, start the nagios service via:
service nagios start
NOTE: Replace "IP_ADDRESS" with the IP address of your NST probe.
