What are the Optimal File Permissions for a Secure WordPress Installation?

Determining Optimal File Permissions for WordPress

When configuring a WordPress installation, it's crucial to set appropriate file permissions to ensure security while allowing necessary access. This question explores the ideal permissions for key directories and files within the WordPress installation.

Recommended File Permissions

For the following directories and files, the recommended permissions are:

• Root folder storing all WordPress content: 755
• wp-admin: 755
• wp-content: 755
• wp-includes: 755
• All files within each of the above directories: 644

Optimal Configuration

Initially, during the WordPress setup, the webserver may require write access to files. Hence, it's acceptable to have slightly less secure permissions:

chown www-data:www-data -R * # Let Apache be owner
find . -type d -exec chmod 755 {} \; # Change directory permissions rwxr-xr-x
find . -type f -exec chmod 644 {} \; # Change file permissions rw-r--r--

After the setup is complete, tighten the access rights to ensure security:

chown <username>:<username> -R * # Let your user account be owner
chown www-data:www-data wp-content # Let Apache be owner of wp-content

Additional Tips

If you need to make changes to files within wp-content after the setup, consider the following options:

• Temporarily switch to the www-data user with su.
• Grant wp-content group write access (775) and join the www-data group.
• Use ACLs to grant your user access to the folder.

Ensure that all files within these directories have rw permissions for www-data to allow proper operation by WordPress.
