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
