推荐答案

首先，使用古老的命令查找系统上运行的其他 mongod 实例:

First of all, look for other instances of mongod running on the system using the age-old command:

ps ax | grep mongod

如果您看到像 -

98555   ??  S      4:40.89 mongod --dbpath /Volumes/ComputerName/data/db 
-PID-                      -name-          -------------path------------

那么已经有一个 mongod 进程正在运行.如果是这样，杀死它，然后再次启动 mongod.

then there is a mongod process running already. If so kill it and then start mongod again.

要杀死 PID = 0000 的进程，在类 Unix 环境中使用 -

To kill a process with PID = 0000, in Unix like environment use -

kill -9 0000

如果您的控制台返回类似 -bash: kill: (98555) - Operation not allowed，请使用

If your console returns something like, -bash: kill: (98555) - Operation not permitted, use

sudo !! 

以超级用户身份重复该命令.这应该能让你继续前进.

to repeat the command as super user. This should get you going.

PS:如果您的数据库中还没有存储任何数据，请删除/data，然后重新创建/data/db 目录.做一个 sudo mongod 就可以了.

PS: If you haven't stored any data in your db yet, delete /data and then create the /data/db directory again. Do a sudo mongod and it should work.
