I've moved redis over from tcp to creating a socket /var/run/redis/redis.sock however I have issues with nginx and php-fpm talking to the socket. Config allows for a unixsocketperm settings which by default suggests 700. Directory and socket user is redis and group is redis. Just after the best suggestion for allowing the various ispconfig web and clients to access the socket ? I have it working with 777, I have tried 750 with group nginx but no luck.
