安装rubygems：yum install rubygems
安装ruby的redis驱动：gem install redis
参考：http://www.cnblogs.com/rwxwsblog/p/5285732.html
pidfile /var/run/redis_6379.pid
logfile /var/log/redis_6379.log
cluster-config-file nodes-6379.conf
cluster-node-timeout 15000
复制相应的配置文件并按上述配置文件修改相应的配置（注意端口和路径）
依次修改相应的配置文件6380.conf、6381.conf、6382.conf、6383.conf、6384.conf、6385.conf
mkdir -p /var/lib/redis/6380 /var/lib/redis/6381 /var/lib/redis/6382 /var/lib/redis/6383 /var/lib/redis/6384 /var/lib/redis/6385
安装并配置完后6379端口的redis实例需要重启，否则会报错
