docker 安装MongoDB以及设置用户

MongoDB 是一个免费的开源跨平台面向文档的 NoSQL 数据库程序。

1、查看可用的 MongoDB 版本

访问 MongoDB 镜像库地址： https://hub.docker.com/_/mongo?tab=tags&page=1。

可以通过 Sort by 查看其他版本的 MongoDB，默认是最新版本 mongo:latest。

你也可以在下拉列表中找到其他你想要的版本：

此外，我们还可以用 docker search mongo 命令来查看可用版本：

[root@topcheer ~]# docker search mongo

3 运行容器

安装完成后，我们可以使用以下命令来运行 mongo 容器：

[root@topcheer ~]# docker run -itd --name mongo  -p 27017:27017 mongo --auth
WARNING: IPv4 forwarding is disabled. Networking will not work.
800f53908b52ed76e31a191bd1885a7eec3b07c46554293a15712dabaecfd45c
[root@topcheer ~]# docker ps -l
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                      NAMES
800f53908b52        mongo               "docker-entrypoint..."   11 seconds ago      Up 9 seconds        0.0.0.0:27017->27017/tcp   mongo
[root@topcheer ~]# docker ps -l
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                      NAMES
800f53908b52        mongo               "docker-entrypoint..."   13 seconds ago      Up 11 seconds       0.0.0.0:27017->27017/tcp   mongo
[root@topcheer ~]# docker ps -l
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                      NAMES
800f53908b52        mongo               "docker-entrypoint..."   14 seconds ago      Up 12 seconds       0.0.0.0:27017->27017/tcp   mongo
[root@topcheer ~]# docker ps -l
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                      NAMES
800f53908b52        mongo               "docker-entrypoint..."   16 seconds ago      Up 14 seconds       0.0.0.0:27017->27017/tcp   mongo

参数说明：

• -p 27017:27017 ：映射容器服务的 27017 端口到宿主机的 27017 端口。外部可以直接通过 宿主机ip:3306 访问到 MySQL 的服务。
• --auth：需要密码才能访问容器服务。

4、安装成功

# 创建一个名为 admin，密码为 123456 的用户。

# 尝试使用上面创建的用户信息进行连接。

root@topcheer ~]# docker exec -it mongo mongo admin
