Changing File Permissions
Each file and directory(folder) in your account has permissions which control who can read, write and execute that file. When files are created, default permissions are assigned. Most users won't need to change permissions, but there are times when an update, instalaltion, etc. will require a file permissions change.
Levels of Access
There are three levels of access for files:
- User: Owns the file
- Group: All users are part of a group of users. The group the file owner belongs to can be granted permissions on the file as set by the owner of that file
- World: Everyone else who isn't either the owner of the file or in the file owner's group.
There are three types of permissions:
Each of those permissions can be set for each of the access classes.
Viewing File Permissions
File permissions can be viewed and changed through either the cPanel File Manager or most FTP programs. We'll walk you through viewing and changing your permissions through the cPanel File Manger here.
File permissions in the cPanel FIle manager will be represented by numbers instead of letters. The numbers are as follows:
7 = read, write, execute
6 = read, write
5 = read, execute
4 = read only
3 = write, execute
2 = write only
1 = execute only
0 = Access Denied
Let's look at an example below:
In the image above you can see the permissions for each file listed on the right side of the screen. Probably the most important thing to keep in mind is that certain file types and folders should be set to particular permissons. Below are some examples:
public_html - 750
Folders - 755
CGI and Perl scripts - 755
.html .php and other Document Types - 644
What to do when permissions are set wrong
Incorrect file permissions can cause errors or even worse, allow unauthorized users to hack your site. Once an unauthorized user gains access, they can further alter more of your file permissions to make a site even more vulnerable. Remember that 777 permissions means that your file is readable, writeable and executable by the "world". This is not common, as it is a rare situation where a file needs to be written and executed by the "world." If you find files or folders with permissions that do not match the default permissons, it's usually best to change them to the recommended permissions.
How to change file permission settings
You can change the permissions for files through the cPanel File Manager or in your preferred FTP program. In File Manager, locate the file you wish to change the permissions for. Next, right click and select Change Permissions from the menu (or select the icon near the top of the screen).
This will bring up the Change Permissions window where you can adjust the settings as needed by checking the box by each permission you want for each level of access (User, Group and World).
Once you are finished editing your file permissions, click the "Change Permissions" button.
Keep in mind that you should only change file permissions if needed. You want to make sure that you aren't allowing more access to your files than is necessary, since that can leave your website vulnerable.
