安装

安装，直接从Ubuntu仓库中安装

如何在 Ubuntu 上安装 MongoDB - 知乎 (zhihu.com)

sudo apt install mongodb

查询服务状态

sudo systemctl status mongodb

看到active（running）表示运行成功了

使用: 控制台直接数据mongo就会进入mongo shell了

lighthouse@VM-20-16-ubuntu:~$ mongo

创建用户，针对上面的Access control is not enabled for the database.这条警告，创建管理员来增强权限控制。

在mongo shell中输入

> db.createUser({user:'root',pwd:'1234',roles:[{'role':'userAdminAnyDatabase','db':'admin'}]})
Successfully added user: {
	"user" : "root",
	"roles" : [
		{
			"role" : "userAdminAnyDatabase",
			"db" : "admin"
		}
	]
}

这样，创建用户就成功了。

mongodb的相关文件

开机自启的配置文件：mongodb.conf

位于：/etc/mongodb.conf

mongodb远程访问配置

修改上述文件，/etc/mongodb.conf，

bind_ip = 0.0.0.0

因为默认绑定的ip是127.0.0.1，外部是无法访问的。

然后重启服务

/etc/init.d/mongodb restart

## mongo可视化工具

window远程连接，可视化的工具，我尝试了一下mongodb-compass，整体感觉还是不错的，可以试试
