第一步：安装

1.1 查找（查看）mongo相应的版本

[root@localhost ~]# docker search mongo

1.2 拉取mongo最新版本镜像

[root@localhost ~]# docker pull mongo
Using default tag: latest
Trying to pull repository docker.io/library/mongo ...
latest: Pulling from docker.io/library/mongo

Status: Downloaded newer image for docker.io/mongo:latest

第二步：创建容器并运行

【备注】注意： [--auth]认证，如果是学习，或者是多服务器的生产环境不建议开启认证，切换数据库需要重新认证。去掉该参数即可。

[root@localhost ~]# docker run -itd --name mongo -p 27017:27017 mongo --auth
WARNING: IPv4 forwarding is disabled. Networking will not work.
c46ebd447cc090732bba4998870e21323264d68c2c69d22ae9826f7c3b36a47f

查看运行状态

[root@localhost ~]# docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                      NAMES
c46ebd447cc0        mongo               "docker-entrypoint..."   10 seconds ago      Up 9 seconds        0.0.0.0:27017->27017/tcp   mongo

第三步：进入mongodb容器

[root@localhost ~]# docker exec -it mongo mongo admin
MongoDB shell version v4.2.6
connecting to: mongodb://127.0.0.1:27017/admin?compressors=disabled&gssapiServiceName=mongodb
Implicit session: session { "id" : UUID("606ee7d9-6b05-4093-b497-92faa0a473b0") }
MongoDB server version: 4.2.6
Welcome to the MongoDB shell.
For interactive help, type "help".

第四步：创建user

> db.createUser({user:'admin',pwd:'123456',roles:[{role:'userAdminAnyDatabase',db:'admin'}]});
Successfully added user: {
	"user" : "admin",
	"roles" : [
		{
			"role" : "userAdminAnyDatabase",
			"db" : "admin"
		}
	]
}

第五步：尝试使用刚刚创建的用户登陆mongodb

> db.auth('admin','123456')
1
>
