MongoDB添加普通用户

本文主要是介绍MongoDB添加普通用户，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

1. 没有管理员用户的话就先建一个

   # /usr/local/mongodb/bin/mongo --host localhost --port 27017
   
   rs:PRIMARY> use admin
   switched to db admin
   rs:PRIMARY> db.createUser({
   ...    "user": "root", 
   ...    "pwd": "密码", 
   ...    "roles": [
   ...            {
   ...                    "role": "userAdminAnyDatabase", 
   ...                    "db": "admin"
   ...            }, 
   ...            {
   ...                    "role": "readWriteAnyDatabase", 
   ...                    "db": "admin"
   ...            }, 
   ...            {
   ...                    "role": "dbAdmin", 
   ...                    "db": "admin"
   ...            }, 
   ...            {
   ...                    "role": "root", 
   ...                    "db": "admin"
   ...            }
   ...    ]
   ... });
   

2. 生成协同文件传输到集群每个节点

   # openssl rand -base64 512 > /usr/local/mongodb/access.key
   # chmod 0600 /usr/local/mongodb/access.key
   

3. 修改配置文件

   cat >> /usr/local/mongodb/mongod.conf << EOF
   auth=true
   keyFile=/usr/local/mongodb/access.key
   EOF
   

4. 重启MongoDB

5. root用户登录验证

   # /usr/local/mongodb/bin/mongo localhost:27017/admin -u root -p
   

6. 添加普通用户

   rs:PRIMARY> use 库名
   rs:PRIMARY> db.createUser({
   ...  user:"用户名",
   ...  pwd:"密码",
   ...  roles:[
   ...   {role:"readWrite",db:"库名"}
   ...  ]
   ... });
