安装
MongoDB
MongoDB
的二进制文件可用于
Linux
、
macOS
、
Windows
和
Solaris
系统。这意味着在大
多数平台上，可以从
MongoDB
下载中心的页面下载一份压缩包，解压并运行二进制文件。
MongoDB
服务器不仅需要一个目录来写入数据库文件
，而且需要一个端口来监听连接。
本节会介绍在两种系统
[W
indows
系统和其他系统（
Linux/Unix/macOS
）
]
中的完整安装
过程。
当说到“安装
MongoDB

开头的版本都是稳定版本
，比如
4.2.0
、
4.2.1
和
4.2.8
。任何以
4.3
开头的版本都是开发版本，比如
4.3.0
、
4.3.2
或
4.3.12
。下面将以
4.2

2.
在开发者着手开发
4.4
版本
（下一个主要的稳定版本）之后，发布了
4.3.0
版本。这是
一个新的开发分支，与
4.2.0
非常相似
，但可能会有一两个额外的特性，也可能存在一
些漏洞。
3.
随着开发者继续添加特性

4.3.2
等版本。这些版本不应该在生产环
境中使用。 ...
