Question

安装了MongoDB 2.67版。当我在终端中运行MongoD（mac os x 10.95）时，这是我收到的消息。（顺便说一下，我试过Sudo）！[错误] [1]

Answer 1

首先尝试：

mongo localhost

查看是否已经有mongod实例在运行。如果没有，您应该删除mongod.lock

sudo rm /data/db/mongod.lock

如果意味着你没有明确关闭mongod。

重要提示：这假设您在数据库中没有任何重要内容，因为它似乎在您的macbook空中运行。

Answer 2

如果您是第一次运行MongoDB，请确保您拥有所有者权限，可以在mongod.lock路径中创建要创建的/data/db文件。

sudo chown -R `id -u` /data/db

无法启动MongoDB吗？
