Deploy Multiple Composer Instances
Intra-service communication must be enabled by making any necessary networking (ports) and firewall changes.
To deploy multiple Composer nodes (or instances) in a new high availability environment:
Install the Composer instance as though it were a single instance (and not running in a high availability environment). See Install Composer v5.
For each instance, run the following commands to set up the environment variables for the installation:
<instance_ip>is the IP address of the Composer instance
<postgres-port>are the host name and port number of the Composer PostgreSQl data store
<postgres-db-password>are the user name and password required to access the Composer PostgreSQL data store.
Obtain the installation script from Composer Technical Support and run:
sudo -E /bin/sh bootstrap-zoomdata.run
After the installation is complete, configure the Consul instance or instances needed for your high availability environment. See Configure the Consul in a High Availability Installation.
Repeat these steps for every Composer instance (node) in your Composer cluster.
