# Caches

# Overview

When provisioning a server Forge will automatically install Memcache and Redis. By default, neither of these services are exposed to the public and may only be accessed from within your server.

# Connecting To Redis

Redis and Memcache are both available via 127.0.0.1 and their default ports.

MEMCACHED_HOST=127.0.0.1
MEMCACHED_PORT=11211

REDIS_HOST=127.0.0.1
REDIS_PASSWORD=null
REDIS_PORT=6379

# External Connections

All Forge servers require SSH key authentication and are not able to be accessed using passwords. Therefore, when using a GUI client or other external client to connect to your cache instance, you will need to use SSH authentication. When selecting the SSH key to use during authentication, ensure that you select your private SSH key.
