所以我不能在我的PHP应用程序中使用蒙戈类。是否由一些端口冲突引起？有没有解决这个问题的方法？
答
如果看到异常，它说：
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
要么mongod的情况下无法创建锁定文件或锁定文件中已存在的位置，以及当前实例不能弄个，由于之前运行的mongod实例不正确的终止/关闭。
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
如果锁文件不存在，给阅读/data/db目录/写权限并重启实例。

我认为它需要管理员权限。
我用过：sudo mongod，它对我来说工作得很好。请尝试。
谢谢，看来我没有为db文件夹权限设置权限。 – Nojan 2014-09-27 14:49:34
