9.3.1. Enabling Replication

You can start the replication process by using the dsreplication enable command. 

$ dsreplication
 enable
 --adminUID admin
 --adminPassword password
 --baseDN dc=example,dc=com
 --host1 opendj.example.com
 --port1 4444
 --bindDN1 "cn=Directory Manager"
 --bindPassword1 password
 --replicationPort1 8989
 --host2 opendj2.example.com
 --port2 4444
 --bindDN2 "cn=Directory Manager"
 --bindPassword2 password
 --replicationPort2 8989
 --trustAll
 --no-prompt

Replication has been successfully enabled.  Note that for replication to
 work you must initialize the contents of the base DN's that are being
  replicated (use dsreplication initialize to do so).

See
/var/.../opends-replication-7958637258600693490.log
for a detailed log of this operation.

To enable secure connections for replication use the --secureReplication1 and --secureReplication2 options, which are equivalent to selecting Configure as Secure in the replication topology options screen of the setup wizard.

As you see in the command output, replication is set up to function once enabled. You must however initialize replication in order to start the process.

[Tip] Tip

When scripting the configuration to set up multiple replicas in quick succession, use the same initial replication server each time you run the command. In other words, pass the same --host1, --port1, --bindDN1, --bindPassword1, and --replicationPort1 options for each of the other replicas that you set up in your script.

If you need to add another OpenDJ directory server to participate in replication, use the dsreplication enable with the new server as the second server.
