Mongodb增加、移除Arbiter节点实例

增加arbiter

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

replset=shard1
replset=shard2
replset=shard3

启动mongod实例。
连接primary.

rs.addarb(“192.168.1.50:10001″)
rs.addarb(“192.168.1.50:10002″)
rs.addarb(“192.168.1.50:10003″)

移除arbiter

rs.remove(“192.168.1.50:10001″)

注意:最好移除结点时候先停掉服务，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.
