Question

当我启动mongo db时，它会立即崩溃并返回到正常的命令行。如果有帮助，我在Mac上运行MEAN堆栈。以下是错误：

$ sudo mongod

Answer 1

首先，使用古老的命令查找在系统上运行的mongod的其他实例：

ps ax | grep mongod

如果您看到像

这样的行

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

然后有一个mongod进程已经运行。如果是这样的话就杀了它然后再次启动mongod。

要杀死PID = 0000的进程，在Unix环境中使用 -

kill -9 0000

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

sudo !!

到repeat the command as super user。这应该让你去。

PS：如果尚未在数据库中存储任何数据，请删除/data，然后再次创建/data/db目录。做一个sudo mongod它应该有效。

Answer 2

我遇到了同样的问题，而这个班轮解决了我的问题

killall mongod

在终端

中运行上述命令

希望有帮助！

Answer 3

我首先打开/data/db/mongod.lock文件，在那里找到我的进程号，然后用kill -9 <processnumber>将其杀死。这对我有用。
