1. macos下MongoDB配置账号密码流程
$ brew services start mongodb
$ mongo
> use admin
> db.createUser({ user: "root" , pwd: "root", roles: ["root"]}) # 创建超级用户
> db.auth('root', 'root') # 验证用户是否设置成功,1为成功
$ vi /usr/local/etc/mongod.conf # 更改mongodb配置文件
配置文件开启强制验证,增加如下内容:
security:
authorization: "enabled"
$ brew services restart mongodb
