mongodb启动错误

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，我正在运行 MEAN 堆栈的 Mac 上。以下是错误:

$sudo mongod

首先，使用古老的命令查找系统上运行的其他 mongod 实例:

ps ax | grep mongod

如果你看到这样的一行 -

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

那么已经有一个 mongod 进程在运行。如果是这样，请杀死它，然后重新启动 mongod。

要杀死 PID = 0000 的进程，在类 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 allowed，请使用

sudo !! 

到 repeat the command as super user .这应该能让你继续前进。

PS:如果你的 db 中还没有存储任何数据，请删除 /data，然后再次创建 /data/db 目录。做一个 sudo mongod 它应该可以工作。
