Each file and folder located in your account has certain permissions assigned. They define who is authorized to write, read or execute this file.
Once it is created in your cPanel, default permissions are assigned. In most cases, there is no need to change them, but certain installations or updates may require a file or folder permissions change.
There are three types of accesses:
- read: The file can be only read mode
- write: The file can be edited
- execute: The file can be executed as a program
- owner: The owner of the file
- group: Files which are in the same folder or group
- world: anyone else
- 0 - no access to the file
- 1 - execute only
- 2 - write only
- 3 - write and execute
- 4 - read-only
- 5 - read and execute
- 6 - read and write
- 7 - read, write and execute (full permissions)
- For all HTML and image files, the permissions have to be set to 644 (or 0644). They will be readable by all the user groups, but writable by the user only. These permissions are set automatically when the file is created.
- Folders the permissions have to be set to 755 (or 0755). The folders will be readable and executed by others, but writable by the user only. These permissions are set automatically when the folder is created.
- For all CGI files, the permissions have to be set to 755 (or 0755). The files will be readable and executed by others, but writable by the user only. These permissions are NOT set automatically once the file is created, you should adjust them manually.
