mysqlsh --uri root@127.0.0.1:3306
After the command is executed, enter the password for logging in to the database of the primary node.

Use the existing MGR to create an InnoDB cluster.

       
            var fandercluster = dba.createCluster('fandercluster')

Check the status of the InnoDB cluster and exit.

fandercluster.status()
In multi-primary mode, 127.0.0.1:3306, 127.0.0.1:3307, and 127.0.0.1:3308 are in R/W mode and are all primary nodes. MGR works properly. It can be concluded that the MySQL InnoDB cluster is deployed successfully.
