无法在Mac OS X上运行mongod

Question

我已经安装mongodb使用homebrew.该mongo命令在终端中按预期运行,但是当我mongod在终端中运行时它返回:

所以我不能在我的php应用程序中使用mongo类.是由一些端口冲突引起的吗？这有什么解决方案吗？

Answer 1

如果你看到Exception,它会说:

exception in initAndListen: 
10309 Unable to create/open lock file: /data/db/mongod.lock 
errno:13 Permission denied Is a mongod instance already running?, terminating

mongod实例无法创建锁定文件或该位置中已存在锁定文件,并且由于先前运行的mongod实例的不正确终止/关闭,当前实例无法获取它.

要解决此问题,请手动删除/data/db/mongod.lock(如果存在)并重新启动mongod服务.

sudo rm /data/db/mongod.lock

如果锁定文件不存在,请提供/data/db目录的读/写权限并重新启动实例.
