MongoDB：无法连接到新的副本集主

Question

尝试为我的 Node.JS 应用程序设置 MongoDB。我运行这个命令：

mongo "mongodb+srv://cluster0-gjc2u.mongodb.net/test"  --username <myusername>

并且每次都得到这个回应。

MongoDB shell version v4.2.1

*** It looks like this is a MongoDB Atlas cluster. Please ensure that your IP whitelist allows connections from your network.

我已将我的 IP 地址列入白名单，并确保一切正常。什么可能导致此问题，我该如何解决？为什么会出现这个问题？

Answer 1

所以你必须注意两件事。

1) 首先，在你的 $PATH 中添加 mongodb，如果你还没有，在主文件夹下创建一个 .bash_profile，然后插入以下内容。（对于 Ubuntu）

export PATH="$PATH: /usr/bin/mongo" 确保将 mongo 的位置放在计算机上。如果您不知道位置，请whereis mongo在终端上键入。保存后，source ~/.bashrc在终端中输入。

2）最后，从 mongodb 图集中复制连接链接，当要求username时password

请提供用于访问数据库而不是 mongdb atlas 帐户的凭据集。
