mongodb中arbiter节点维护：增加与移除arbiter节点

mongodb增加与移除arbiter节点

一、增加Arbiter节点

增加配置文件mongod1,mongod2,mongod3分别为shard1，shard2，shard3三个set集合的arbiter。
 

启动mongod实例。

连接Primary.
 

二、移除Arbiter
 

注意，最好移除结点时先停掉服务，防止有特殊未知状态出现。
Note:Before running the rs.remove() operation, you must shut down the replica set member that you're removing.
Changed in version 2.2: This procedure is no longer required when using rs.remove(), but it remains good practice.
