To install the Redis key/value store, log in to your server as the root user and run the following command:
sudo apt-get install redis-server
Once installed, Redis will listen on port 6379.
Only use Redis on a single-app server. The data stored in Redis will be accessible to all apps on your server, so it is not secure to use Redis on a server with more than one app.
Accessing Redis from PHP
To interact with the Redis server from your PHP scripts, you need to install the PHP Redis client extension.
Redis Monitor
While developing or debugging your application, you can view every command processed by the Redis server by running the following command:
$ redis-cli monitor 1339518083.107412 [0 127.0.0.1:60866] "keys" "*" 1339518087.877697 [0 127.0.0.1:60866] "dbsize" 1339518090.420270 [0 127.0.0.1:60866] "set" "x" "6" 1339518096.506257 [0 127.0.0.1:60866] "get" "x" 1339518099.363765 [0 127.0.0.1:60866] "del" "x" 1339518100.544926 [0 127.0.0.1:60866] "get" "x"
Use Ctrl-C to exit monitoring.
Customizing Your Firewall for Redis
The firewall configured by SellCloud will block all access to Redis from outside of your server. If you need to have other servers access Redis, you'll need to customize your firewall using a tool such as HeatShield.
