安装fedora的YUM源，
rpm -Uvh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-7.noarch.rpm
安装redis
# yum install redis # chkconfig redis on # service redis start
备份配置文件，
# cp /etc/redis.conf /etc/redis.conf.original
主从同步配置非常简单，只需在从服务器 /etc/redis.conf 文件中开启 slaveof 即可
slaveof 192.168.2.1 6379
查看 /var/log/redis/redis.log 日志，可以看到同步情况
