Correctly repair Wordpress permissions (Redhat, CentOS, Debian, Ubuntu, MacOS, etc.)

wp_perms.sh

#!/bin/bash
#
# run with:
# ./wp_perms.sh {path}
#
OWNER=apache # Wordpress owner, or the user that runs php. On CentOS/Redhat this is usually apache. On Ubuntu/Debian, this could be www-data
GROUP=apache # Configure your own group, or use the group from the user above (apache, www-data, etc.)
ROOT=$1 # Specify path when invoking this script
 
# Reset permissions to defaults
find ${ROOT} -exec chown ${OWNER}:${GROUP} {} \;
find ${ROOT} -type d -exec chmod 755 {} \;
find ${ROOT} -type f -exec chmod 644 {} \;
 
# Make wp-config non-public
chgrp ${GROUP} ${ROOT}/wp-config.php
chmod 660 ${ROOT}/wp-config.php
 
# Give Wordpress the permissions it needs
find ${ROOT}/wp-content -exec chgrp ${GROUP} {} \;
find ${ROOT}/wp-content -type d -exec chmod 775 {} \;
find ${ROOT}/wp-content -type f -exec chmod 664 {} \;
