---------------------
连接上mongos添加的用户会保存在config副本集中，但是不会保存到shard副本集，因此添加用户的操作需要分别在config、shard1、shard2、shard3上执行
db.createUser({user:"admin",pwd:"eos@2018",roles:[{role:"root",db:"admin"}]})
db.auth("admin","eos@2018")
db.createUser({user:"eos",pwd:"20190808",roles:[{role:"readWriteAnyDatabase",db:"admin"}]})
redis密码：eos2019
修改密码
db.changeUserPassword('eos','20190808')
mongodb://eos:[email protected]:27010,192.168.1.172:27010,192.168.1.173:27010/admin?connectTimeoutMS=5000

sh.stopBalancer()
sh.startBalancer()
##如果balance开启，查看是否正在有数据的迁移
