Redis

Redis is an in memory data structure storage. It will be used to share PHP-sessions between the apache servers. To guarantee a robust deployment three redis servers will be configured.

192.168.1.58 redis01
192.168.1.59 redis02
192.168.1.60 redis03

Software

apt-get install redis-server

Configuration

Make sure the apache servers can reach redis. Change bind 127.0.0.1 in /etc/redis/redis.conf. Each of the redis server needs to listen on its own IP-address.

bind 127.0.0.1 192.168.1.58

-Guess we need to do some kind of configuration.
