启动 MongoDB，并设置开机启动

sudo systemctl start mongod
sudo systemctl enable mongod # 设置开机启动
sudo systemctl status mongod # 查看 mongod 运行状态，如果输出中包含 active (running)字样说明 mongod 成功启动

查看是否安装成功

mongo --quiet "mongodb://127.0.0.1:27017"

创建管理员账户

$ mongo --quiet "mongodb://127.0.0.1:27017"
Welcome to the MongoDB shell.
> use admin
switched to db admin
> db.createUser({user:"root",pwd:"root",roles:["root"]})
Successfully added user: { "user" : "root", "roles" : [ "root" ] }
> db.auth("root", "root") #登录

删除用户，可以使用 db.dropUser("用户名")

使用管理员账户登录，创建一个 iam 普通用户来连接和操作 MongoDB

$ mongo --quiet mongodb://root:'root'@127.0.0.1:27017/tyk_analytics?authSource=admin
> use iam_analytics
switched to db iam_analytics
> db.createUser({user:"iam",pwd:"iam",roles:["dbOwner"]})
Successfully added user: { "user" : "iam", "roles" : [ "dbOwner" ] }
> db.auth("iam", "iam")
1

使用刚创建的普通账户登录

mongo --quiet mongodb://iam:'iam'@127.0.0.1:27017/iam_analytics?authSource=iam_analytics

修改密码

db.changeUserPassword('root','iam59!z$')
