mongodb - 每当我启动本地服务器时，WSL2 ubuntu Mongod 都会不断更改端口

问题描述

我按照这个链接在 ubuntu wsl 上设置了 mongodb，它有点工作 https://github.com/michaeltreat/Windows-Subsystem-For-Linux-Setup-Guide/blob/master/readmes/installs/MongoDB.md

但是，每当我使用命令sudo mongod --dbpath ~/data/db

它将在本地打开一个 Mongod 服务器并显示这个

然后，如果我使用 mongo 数据库启动应用程序，我会得到这个

我试图将它保持在同一个端口上，这样我就可以使用 mongodb compass 并将它转到我选择的某个数据库。像 RedditClone 或 todoApp 数据库。但是，如果我在该 IP 中键入它不存在，并且我可以从该数据库中看到任何内容的唯一方法是在 javascript 中使用 .find({}) 。请帮忙 ：（

解决方案

你的实际问题是什么？日志中的所有内容都表明您已设置服务器并且能够成功连接到它（从您的本地计算机）。Compass 似乎没有提供设置默认数据库的方法，例如 mongo shell 命令行。如果您可以浏览可用的数据库或在 Compass 中创建新数据库，则您已连接到服务器。

2020-05-07T14:50:57.489-0700 I NETWORK  [initandlisten] waiting for connections on port 27017

此行表示您启动了服务器，它正在侦听 localhost:27017

2020-05-07T14:53:19.392-0700 I NETWORK  [listener] connection accepted from 127.0.0.1:60332 #1 (1 connection now open)

此行表示新客户端成功地从端口 60332 打开了与此服务器的连接（在您的情况下托管在端口 27017 上）。

如果您运行 mongo shell，您将在日志中看到另一个连接到服务器的打开。每个客户端（在您的情况下听起来像 Compass）都将在动态端口上运行，因此您可以同时运行多个客户端。您不连接到客户端端口，只连接到服务器。客户端端口告诉服务器将结果返回到哪个端口。

URL 中指定的数据库是身份验证数据库，由于您没有启用身份验证，因此将其忽略。引用文档：

mongodb://[username:password@]host1[:port1][,...hostN[:portN]][/[defaultauthdb][?options]]

...

默认身份验证数据库

可选的。如果连接字符串包含 username:password@ 身份验证凭据但未指定 authSource 选项，则要使用的身份验证数据库。

如果 authSource 和 defaultauthdb 都未指定，客户端将尝试向 admin 数据库验证指定用户。
