Starting Multiple Instances of an OpenIM Service

To start multiple instances of an OpenIM service, simply increase the corresponding port numbers and modify the start-config.yml file in the project root directory. Restart the service to take effect. For example, the configuration to start 2 instances of openim-rpc-user is as follows:

rpc:
  registerIP: ''
  listenIP: 0.0.0.0
  ports: [ 10110, 10111 ]

prometheus:
  enable: true
  ports: [ 20100, 20101 ]

Modify start-config.yml:

serviceBinaries:
  openim-rpc-user: 2
