Setting read/write permissions on Mongodb folder
提问by Zoltan King
I just finished installing MongoDB on OSX and setup a directory structure with sudo mkdir -p /data/db.
我刚刚在 OSX 上安装完 MongoDB 并使用sudo mkdir -p /data/db.
When I attempt to run mongodfrom my user account it returns an error stating that my user account does not have read/write permission to /data/db.
当我尝试mongod从我的用户帐户运行时，它返回一个错误，指出我的用户帐户没有对/data/db.
How can I set the proper read/write permissions on my account for /data/db?
如何为我的帐户设置正确的读/写权限/data/db？

Ensure that user account running mongodhas the proper directory permissions. You can check which permissions are set like so:
确保运行的用户帐户mongod具有适当的目录权限。您可以像这样检查哪些权限设置：
ls -ld /data/db/
If they are set properly they should look something like this..
如果它们设置正确，它们应该看起来像这样..
drwxr-xr-x X user wheel XXX Date Time /data/db/
drwxr-xr-x X user wheel XXX Date Time /data/db/
If the permissions are set incorrectly you will likely see an error similar to this when attempting to run mongod
如果权限设置不正确，您可能会在尝试运行时看到与此类似的错误 mongod
exception in initAndListen: XXXXX Unable to create/open lock file: /data/db/mongod.lock errno:13 Permission denied Is a mongod instance already running?, terminating
exception in initAndListen: XXXXX Unable to create/open lock file: /data/db/mongod.lock errno:13 Permission denied Is a mongod instance already running?, terminating
To get the permissions set as they should be you can run the following command
要获得应有的权限设置，您可以运行以下命令
sudo chmod 0755 /data/db && sudo chown $USER /data/db

sudo chmod 777 /data/db/
Should work on Mac. Before running this cmd, permissions look like
应该在 Mac 上工作。在运行这个 cmd 之前，权限看起来像
drwxr-xr-x X User wheel Date /data/db
after running the cmd
运行cmd后
drwxrwxrwx X User wheel Date /data/db

This is what worked for me. I am using a Mac, although you could try if you're using windows.
这对我有用。我使用的是 Mac，不过如果您使用的是 Windows，您可以尝试一下。
sudo chmod 777 /data/db

There are three categories of users: owners, those in the group, and everyone else; chmod 777 /path/to/filelets everyone read/write the file, but chmod 775 /path/to/filelets only the owner/group read/write the file. Definitely use chmod 775 /path/to/fileif you're developing a web server.
用户分为三类：所有者、组内用户和其他所有人；chmod 777 /path/to/file允许每个人读/写文件，但chmod 775 /path/to/file只允许所有者/组读/写文件。chmod 775 /path/to/file如果您正在开发 Web 服务器，请务必使用。
Some useful reading, especially for reasoning behind why 777, 775, and so on are used rather than other numbers: https://www.maketecheasier.com/file-permissions-what-does-chmod-777-means/

None of these suggestions are correct, there's something else wrong with mongodb-org-3.4.16-1.el7.x86_64. It cannot start with a custom db path.
这些建议都不正确，mongodb-org-3.4.16-1.el7.x86_64 还有其他问题。它不能以自定义数据库路径开头。
[root@localhost vagrant]# chmod 777 /data/ /data/mongodb
[root@localhost vagrant]# chown mongod:mongod /data/ /data/mongodb
[root@localhost vagrant]# ls -lad /data/mongodb/

[root@localhost vagrant]# systemctl start mongod
Job for mongod.service failed because the control process exited with error code. See "systemctl status mongod.service" and "journalctl -xe" for details.

None of the given answers were working for me. I ended up configuring my personal OS user to be the root user, then manually went to the db folder - right clicked to view info - and added myself with read and write permissions.
没有一个给定的答案对我有用。我最终将我的个人操作系统用户配置为 root 用户，然后手动转到 db 文件夹 - 右键单击以查看信息 - 并为自己添加了读写权限。
