Starting Multiple Nodes

There are several use cases for using multiple nodes.

• Additional nodes are created with the goal of scaling horizontally.
  For example, if you have three copysets, start the components in the following sequence:

  tibrealmserver
  tibdg -r http://localhost:8080 -s /<path>/three_copysets.tibdg
  tibdgkeeper -r http://localhost:8080 -n k1
  tibdgproxy -r http://localhost:8080 -n p1
  tibdgnode -r http://localhost:8080 -n s1
  tibdgnode -r http://localhost:8080 -n s2
  tibdgnode -r http://localhost:8080 -n s3

  Here <path> refers to the location where three_copysets.tibdg is stored. For a sample script, see three_copysets.tibdg.
• Nodes are created as replicas of the copysets.
  For example, if you have one copyset and two replicas, start the components in the following sequence:

  tibrealmserver
  tibdg -r http://localhost:8080 -s /<path>/one_copyset_two_replicas.tibdg
  tibdgkeeper -r http://localhost:8080 -n k1
  tibdgproxy -r http://localhost:8080 -n p1
  tibdgnode -r http://localhost:8080 -n s1
  tibdgnode -r http://localhost:8080 -n s2

  Here <path> refers to the location where one_copyset_two_replicas.tibdg is stored. For a sample script, see one_copyset_two_replicas.tibdg.

node create --copyset set1 --dir ./s1_data s1
statekeeper create --dir ./k1_data k1

• three_copysets.tibdg
  
• one_copyset_two_replicas.tibdg
