【副本集部分】
 按照如下方式修改每个分片的副本集的主从关系、config的副本集主从关系

config=rs.conf()

config.members[0].host ="10.9.110.116:30001"

rs.reconfig(config,{force:true})

 根据实际情况，更改每个节点的IP地址信息，config.members[0]的数字是根据rs.conf()显示的自然排序来的，从0开始，并非id
【shard部分】

 修改mongos记录分片的IP地址

>use config;

>db.shards.find()

{ "_id" : "kk-comic-test-shard02", "host" : "kk-comic-test-shard02/10.9.70.22:30004,10.9.70.22:30005" }

{ "_id" : "kk-comic-test-shard03", "host" : "kk-comic-test-shard03/10.9.70.22:30007,10.9.70.22:30008" }

{ "_id" : "kk-comic-test-shard01", "host" : "kk-comic-test-shard01/10.9.110.116:30001,10.9.110.116:30002" }

将上述地址进行如下更改： 

>db.shards.update( { "_id" : "kk-comic-test-shard02" }, { $set: { "host": "kk-comic-test-shard02/10.9.110.116:30004,10.9.110.116:30005" } }, { multi: true })

>db.shards.update( { "_id" : "kk-comic-test-shard03" }, { $set: { "host": "kk-comic-test-shard03/10.9.110.116:30007,10.9.110.116:30008" } }, { multi: true })

>db.shards.update( { "_id" : "kk-comic-test-shard01" }, { $set: { "host": "kk-comic-test-shard01/10.9.110.116:30001,10.9.110.116:30002" } }, { multi: true })
