What File Permissions for Apache File/Folders

It is important to provide the right file/folder permissions for Apache to be able to access your website’s files and directories. Otherwise you may see an error message on your website. In this article, we will look at the proper file permissions for Apache file/folders. You can think of them as Apache File Permissions Best Practices.

What File Permissions for Apache File/Folders

root is the default owner of files & folders in /var/www/html folder (which is typically Document Root) for your website. Also the file permissions are 755. It means other users cannot access these files easily.

Here are the steps to set the right file permissions for Apache file/folders. We will set our Linux user ubuntu as the owner of website directory with full read, write & execute permissions. We will also make the web server as the group owner with read and execute permissions. Others will not have any permission to access your entire website directories & files.

1. Set Your User

Let us say your website files & folders are located at /var/www/html. First we will set our user ubuntu to be the owner of these files.

$ sudo chown -R ubuntu /var/www/html/

In the above command, we use -R flag to recursively change the owner of all files & folders in your website’s document root.

2. Set web server as group owner

By default, Apache and NGINX use www-data as the user for web server. We will make it as group owner of our website’s files & folders.

$ sudo chgrp -R www-data /var/www/html/

3. Set 755 permission for al file & folders

We will set permission 755 for all files & directories in our website. It means owner can read, write & execute; group owner & others can read & execute.

$ sudo chmod -R 755 /var/www/html/

If you want to be super restrictive, you can use 750 instead of 755 in above command. owner can read, write & execute; group owner can read & execute, and no permission for others. But be careful in this case if since you are not the owner and not member of permitted group above, you may not be able to access these files.

4. Inherit permissions

Next, we need to ensure that if new files & folders are added to your website, they inherit the same group ownership from parent folder. You can do this with the following command where we use s flag for this purpose.

$ sudo chmod g+s /var/www/html/

If you also require your web server to be able to write to files & folders, you can modify the above command as shown below.

$ sudo chmod g+w /var/www/html/

Now all file permissions for directories and files in your Document root will be set appropriately.
