macos - 无法在 Mac OS X 上运行 mongodb

Question

我已经使用 homebrew 安装了 mongodb。 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。是不是端口冲突导致的？有什么解决办法吗？

Answer 1

如果您看到异常，它会显示:

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

由于先前运行的 mongod 实例的不正确终止/关闭，mongod 实例无法创建锁定文件或锁定文件已存在于该位置，并且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，请授予 /data/db 目录的读/写权限并重启实例。
