Moving master and Director to another server

Icinga 2
1

Hi,

I have an Icinga2 monitoring setup with one master with Director and 2 satellites in 3 different data centers,
now I need to move the master, and director, to one of the satellites as we need to close down the DC holding the current master…

Is there any procedure to move a master (with director) ?
Or any advice, cook-book ?

Any help would be very welcome :wink:

Thanks,
Chris

the easiest way would be to copy

/etc/icinga2
/etc/icingaweb2

and after that make a dump of the director and icinga DBs and restore them on the new master. I would suggest making a testrun of it, as this can work, but there may be some problems depending on your configuration

Hi,

keep in mind that the master also holds the Icinga CA. My consideration would therefore be:

  • “Drop” the satellite configuration (do a backup beforehand)
  • Move the entire master configuration (have a look in the backup chapter in the documentation)
  • Dump databases (ido, director, web2, etc.)
  • Configure web server
  • Optional: setup features (InfluxDB, Graphite, etc.)

How do the agents and/or other satellites connect to old master? If the master establish a connection this is easy, as the new master can establish the connection as well. If the agents/satellites build up the connection (either via IP or FQDN) there is more work to do. You can point the FQDN to the new master and/or assign the IP address of the old master to the new master, to ensure the agents/satellites can connect.

Thanks for your answers, appreciate :slight_smile:

I was also thinking about adding a new server in the master zone and then remove former one but I’m not sure it would transfer role automatically as well as certs etc…
Also would it juts take a backup/restore of director db on the new one ?

I have some kinda same setup, but already have two masters running where each master has it’s own database for icingaweb.

I would like to switch roles between the two masters and then phase out master1. (master1=configmaster, master2=backmaster)

  1. zones.conf is already the same - no need to change (?)
  2. databases and icingaweb is already up and running - no need to change (?)
  3. certs? Should I transfer /var/lib/icinga2/ca (Master CA key pair) ?
  4. Move all the zones.d/* files to the 2nd master or the whole /etc/icinga2 ?
  5. Reset needed on 2nd master so it syncs correctly or clean up cache files ?

Hope some can point me in the right direction.
