Icinga Web on a dedicated host
Requirements
- Central database server or cluster with a virtual IP address (VIP)
- Icinga 2’s IDO feature is writing to the database on the central server
Setup
- Store the Icinga Web database in the central database server

Icinga Web with two HA masters
Decide whether you want to install Icinga Web 2 locally on each master instance, or put it on a dedicated host (see above).
The recommended setup is to use a central database server with a VIP and described below.
HA with local Icinga Web
Requirements
- Every master has a local Icinga Web 2 installation
- Icinga 2 has the IDO feature enabled with
enable_ha = true
, only one instance actively writes to the central database
Setup
- Set the IDO database resource to the central database server
- Configure the command transport to send commands to this instance locally
- Configure the Director to use the local REST API for deployments
HA with central Icinga Web
Requirements
- Icinga Web runs on either one of the masters, or on its own dedicated host
- Icinga 2 has the IDO feature enabled with
enable_ha = true
, only one instance actively writes to the central database
Setup
- Set the IDO database resource to the central database server
- Configure the command transport to send commands to both instances with fallback mode
- Configure the Director to use the primary master’s REST API for deployments
