Question

我有2个终端窗口，第一个用于运行服务器，第二个用作客户端以连接到db服务器。
我已成功连接到本地mongoDB服务器。

终端窗口1

bogdanmac:~ iliebogdanbarbulescu$ 
bogdanmac:~ iliebogdanbarbulescu$ brew services start mongodb-community@4.2
Service `mongodb-community` already started, use `brew services restart mongodb-community` to restart.

很遗憾，我无法从客户端访问数据库。

终端窗口2

Answer 1

感谢@Abhishek kumar，更改了.sock文件的权限后，我可以使用命令mongo启动客户端了

设置.sock文件的权限给当前用户：

sudo chown whoami /tmp/mongodb-27017.sock

Answer 2

因此，我们可以在本文结束时提供解决方案，以检查.sock文件的权限并更改.sock文件的权限。

   Change the permission of .sock file.
