Building an Orchestrator cluster
In this recipe, we are building an Orchestrator cluster and configuring it for HA. Load-balancing is discussed in a separate recipe in this chapter.
Getting ready
The prerequisites for a cluster are not that hard, but they are important:
- Shared DB: Please have a look at the recipe Configuring an external database in Chapter 1, Installing and Configuring Orchestrator. Also, check that you have set the required extras as stated in the There's more... section of the recipe Configuring an external database. This is especially important if you are using an MS SQL DB. Also note that if you're serious about HA, you may want to use a DB cluster.
- You need two Orchestrator installations. It's best to use fresh ones, each with fixed IPs.
- Make sure NTP is configured and the time is synced.
- You should be familiar with the content of the recipe Important Orchestrator settings in Chapter 1, Installing and Configuring Orchestrator, as well...
