上面报错是因为我配置文件中写的是本机ip,更换后

>### 用户管理
添加超级用户
use admin
db.addUser(‘name‘,‘password‘)
添加只读用户
use dbname
db.addUser(‘name‘,‘password‘,true)
添加普通用户
use dbname
db.addUser(‘name‘,‘password‘) 其实也不能说是普通用户，这个只是针对于某一个数据库有权限
删除用户
use dbname
db.system.users.remove(‘name‘,‘password‘)
更换用户密码
use dbname
db.addUser(‘name‘,‘password‘)
切换用户（必须要先到对对应的数据库，root账户除外）
use dbname
db.auth(‘name‘,‘password‘)
查找用户
use dbname
db.system.users.find()
### 监控mongodb
1、db.serverStatus()可以查看系统的大部分状态
