Manage Redis

You can ask us to install separate Redis instances for each use:

• Application Cache
• Sessions
• Full Page Cache
• A queue

If you plan to use Varnish, you don't need a Redis for the Full Page Cache.

Use Redis

We use a Unix Socket to connect to Redis, except when your shop is hosted a server cluster.
These sockets are located here:

/home/__USERNAME__/.config/redis/run/redis-cache.sock
/home/__USERNAME__/.config/redis/run/redis-session.sock
/home/__USERNAME__/.config/redis/run/redis-fpc.sock

You can use this socket path as server or hostname in the configuration.
You can set the port to 0
  

Clean Redis Cache

You may run into a situation where something is broken in the Magento cache, which prevents you from using the Admin or N98-Magerun to clean it. The command below will connect directly to the Redis instance, en execute a FLUSHDB.
This command has the same effect as clearing the cache directory when you would be using a File cache.

~/bin/clean_redis-cache.php

Clean Redis Session

It is probably not a good idea to execute this on live because all visitors will lose their shoppingcart. You can use this on a Staging account during development.

~/bin/clean_redis-cache.php

Clean Redis Full Page Cache

When you are using FPC in Redis, this command will remove all cached data.

~/bin/clean_redis-fpc.php

Use Redis CLI

The number after -n in the commands below is the database number.
These are our defaults, but you may be using different numbers.

To manage the Redis Cache:

redis-cli -n 0 -s "${HOME}/.config/redis/run/redis-cache.sock"

To manage the Redis for Full Page Cache (FPC):

redis-cli -n 1 -s "${HOME}/.config/redis/run/redis-fpc.sock"

To manage the Redis for Sessions via Redis CLI:

redis-cli -n 2 -s "${HOME}/.config/redis/run/redis-session.sock"
