我使用mongodb安装了homebrew。 mongo命令在终端中按预期运行，但是当我在终端中运行mongod时，它返回：
mongod --help for help and startup options

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？
答案 0 :(得分：5)
如果您看到异常，则说：
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。
答案 1 :(得分：0)
我认为它需要管理员权限。
我用过：sudo mongod，它对我来说很好用。请试一试。
