Mongod抱怨没有/data/db文件夹

今天我第一次用我的新mac电脑。我遵循mongodb.org上的入门指南，直到创建/data/db目录的步骤。顺便说一句，我用的是自制路线。

所以我打开一个终端，我认为我在你所谓的主目录，因为当我按“ls”时，我看到桌面应用程序、电影、音乐、图片、文档和库的文件夹。

所以我做了一个

mkdir -p /data/db

首先，它说许可被拒绝。我不停地尝试了半个小时，最后:

mkdir -p data/db

工作。当我“ls”，一个目录的数据和嵌套在其中的db文件夹确实存在。

然后我启动mongod，它抱怨找不到data/db

我做错什么了吗?

现在我已经完成了

sudo mkdir -p /data/db

当我执行“ls”时，我确实看到了data dir和db dir。在db目录下，什么都没有，当我运行mongod

编辑获取错误消息

sudo chown mongod:mongod /data/db

chown: mongod: Invalid argument

谢谢,大家好!

如果你使用Mac并运行Catalina和通过Homebrew安装Mongodb，你要做的就是输入这个命令，你就可以开始了。

brew services start mongodb-community

简单说明一下:

If you tried running mongod without changing the permissions first, you'll likely have a mongod.lock file (and some other files) in the /data/db directory. Even after you change the permissions for the /data/db directory to give access to your $USER, you'll continue to get the "Unable to create/open lock file: /data/db/mongod.lock errno:13 Permission denied" error. Run ls -al /data/db and you'll probably see that the permissions for the individual files are still set to root for user, not to your $USER. You should remove the mongod.lock file, and the others as well. Then when you run mongod again, everything should work, and you can verify that the file permissions match the directory permissions by running ls -al again.

MongoDB可能会对dbPath文件夹感到困惑。

当你运行mongod而不使用dbpath时，默认路径是/data/db

然而，当你把它作为一个服务启动时，例如systemctl start mongod，它会读取配置文件，通常是/etc/mongod.cfg，在这个配置文件中，默认值是
