命令一键部署

拉取镜像

# docker pull mongdo:4.0.3
1

方式一：

数据为持久化：不挂载容器卷

# docker run -itd --name mongo -p 27017:27017 mongo --auth
1

• -itd 交互后台运行容器
• –name 自定义容器名称

创建mongoDB账号

1）进入容器创建数据库访问用户账号密码，并且尝试连接

[root@nhk ~]# docker exec -it mongo mongo admin
MongoDB shell version v5.0.5
connecting to: mongodb://127.0.0.1:27017/admin?compressors=disabled&gssapiServiceName=mongodb
Implicit session: session { "id" : UUID("2c914490-5b3d-4c44-b85f-abc0963cf2c2") }
MongoDB server version: 5.0.5

Successfully added user: {
	"user" : "admin",
	"roles" : [
		{
			"role" : "userAdminAnyDatabase",
			"db" : "admin"
		},
		"readWriteAnyDatabase"

方式二：

数据持久化：挂载容器卷

# docker run --name my_mongo -v /opt/data/mongodb:/data/db --rm -d -p 27017:27017 mongo:4.0.3
1

参数说明：

• -itd 交互后台运行容器
• –name 自定义容器名称
• -p 27017:27017 容器服务的 27017 端口映射到宿主机的 端口 27017，那么外部可以通过 宿主机 IP:27017 访问容器内 mongo。
• 镜像名
• –auth 需要密码才能访问容器服务

进入容器

# docker exec -it mongo /bin/bash
1

使用mongo客户端

mongo
