>rs.initiate (config)

Initialize Rs.initiate (config), config is the name defined previously

When the master and standby library is configured, the standby library is queried.

Rs.stauts () can look at the state, Health:1 stands for health, statestr who is our arbitration

Want to downgrade the main library to from the Library, Rs.stepdown ()
