Hi,

how to migrate configuration file from one nagios server to other nagios server. Please provide document.

We have one running nagios server, created new nagios one need to move the all configuration from old to new.

Which "Nagios" are you using?

Nagios XI or Nagios Core? Or a different product? Nagios Fusion, Nagios Log Server, Nagios Network Analyzer?

What version is the old and what version is the new?

Our old nagios server is Nagios XI 5.2.0 and the new server is Nagios XI 5.4.13

You should be able to perform a backup and then restore just fine

However, one thing to point out is that I want to point out is that this restore will bring you back to 5.2.0, so you will then want to perform an upgrade.

If we have take the backup from Nagios XI 5.2.0 and can we restore the backup to new server Nagios XI 5.4.13

Whatever version the software is when you back it up is the version it will be when you restore it. We do not advise restoring an older version over a newer one.

then except restore, is there any way to move configuration file from old nagios server Nagios XI 5.2.0 to nagios server Nagios XI 5.4.13?

i tried restore the backup but i got a warning saying resore a OS 6 backup on a OS 7 system

Compiled plugins and other binaries as welll as httpd configurations will not be restored

after restore getting the below error

Run the following from the CLI as root to attempt to repair the DB

/usr/local/nagiosxi/scripts/repair_databases.sh

Run the following on the new server:

cat /usr/local/nagiosxi/html/config.inc.php | sed -rn "/\"ndoutils\" => array\(*/,/\"dbmaint\"/p" | grep -o -P '(?<="dbserver" => ).*(?=,)' | tr -d \'

If the database is not hosted on localhost, then you'll need to update your datbase's config to allow the new machine to connect. https://assets.nagios.com/downloads/nag ... Server.pdf contains the commands to be run on the database server:

mysql -u root -p'mypassword'
create database nagios;
GRANT ALL ON nagios.* TO nagios@'<IP_OF_NAGIOS_XI_SERVER>' IDENTIFIED BY 'nagios';
create database nagiosql;
GRANT ALL ON nagiosql.* TO nagiosql@'<IP_OF_NAGIOS_XI_SERVER>' IDENTIFIED BY 'nagiosql';
create database nagiosxi;
GRANT ALL ON nagiosxi.* TO nagiosxi@'<IP_OF_NAGIOS_XI_SERVER>' IDENTIFIED BY 'nagiosxi';
quit;
