PHP: Correct file permissions for WordPress
When you setup WP you (the webserver) may need write access to the files. So the access rights may need to be loose.
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 you should tighten the access rights, according to Hardening WordPress all files except for wp-content should be writable by your user account only. wp-content must be writable by www-data too.
chown <username>:<username> -R * # Let your useraccount be owner chown www-data:www-data wp-content # Let apache be owner of wp-content
Maybe you want to change the contents in wp-content later on. In this case you could
- temporarily change to the user to www-data with su,
- give wp-content group write access 775 and join the group www-data or
- give your user the access rights to the folder using ACLs.
Whatever you do, make sure the files have rw permissions for www-data.
