First of all, look for other instances of mongod running on the system using the age-old command:
首先，使用 age-old 命令查找系统上运行的其他 mongod 实例：
ps ax | grep mongod
If you see a line like -
如果你看到这样的一行 -
98555 ?? S 4:40.89 mongod --dbpath /Volumes/ComputerName/data/db
-PID- -name- -------------path------------
then there is a mongod process running already. If so kill it and then start mongod again.
那么已经有一个 mongod 进程正在运行。如果是这样，请杀死它，然后再次启动 mongod。
To kill a process with PID = 0000, in Unix like environment use -
要杀死 PID = 0000 的进程，请在类 Unix 环境中使用 -
kill -9 0000
If your console returns something like, -bash: kill: (98555) - Operation not permitted, use
如果您的控制台返回类似的内容-bash: kill: (98555) - Operation not permitted，请使用
sudo !!
to repeat the command as super user. This should get you going.
PS: If you haven't stored any data in your db yet, delete /dataand then create the /data/dbdirectory again. Do a sudo mongodand it should work.
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，它应该工作。

I first opened the /data/db/mongod.lock file, found my process number there, then killed it with kill -9 <processnumber>. That worked for me.
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>. 那对我有用。
