因为我这测试，只有一个config，若是多个的话，在members 数组中配置上即可。
如：
rs.initiate({_id:"cfgReplSet", configsvr:true, members:[{_id:0, host:"172.20.4.132:21000"}，{_id:0, host:"172.20.4.133:21000"}，{_id:0, host:"172.20.4.134:21000"}]})
也可以用add的方式追加，如后续新加入的副本
rs.add("172.20.4.133:21000") # 添加备份库
rs.addArb("172.20.4.134:21000")#添加仲裁

新建 test db

查看当前使用的db

为test db 添加用户 test 密码 111111

验证用户登录

成功
这时插入数据会报错，因为db test没有配置shard
mongos> db.test.insert({"name":"mayun","age":"50"})
WriteResult({
"writeError" : {
"code" : 70,
"errmsg" : "unable to target write op for collection test.test :: caused by :: ShardNotFound: Database test not found due to No shards found"

为数据库配置shard
将之前的shard加入到mongos，以便路由
mongos> sh.addShard("shard1ReplSet/172.20.4.132:22001")
{ "shardAdded" : "shard1ReplSet", "ok" : 1 }
mongos> sh.addShard("shard2ReplSet/172.20.4.132:22002")
{ "shardAdded" : "shard2ReplSet", "ok" : 1 }
mongos> sh.addShard("shard3ReplSet/172.20.4.132:22003")
{ "shardAdded" : "shard3ReplSet", "ok" : 1 }
这里添加的副本集，只需要是副本集名加上一个副本集中的成员即可，不一定要是primary节点。
设置 库 集合（表）的分片
mongos> sh.enableSharding("test")
{ "ok" : 1 }
mongos> sh.shardCollection("test.user",{"_id":"hashed"})
{ "collectionsharded" : "test.user", "ok" : 1 }
