MongoDB's Replset copy set

copy set of # # # MongoDB

# # # Note the point

- 服务器节点之前时间要同步

- 开启防火墙的一定要允许通过

- open also set to

- It's best to build double-click Trust mode

# # # Master server configuration file

• MongoDB's Replset replica set is a cluster approach that MongoDB officially recommends
