?? ??? ?[root@ractdg3 redis-2.8.4]# cp redis.conf redis_master.conf
?? ??? ?[root@ractdg3 redis-2.8.4]# cp redis.conf redis_slave.conf
?? ??? ?[root@ractdg3 redis-2.8.4]# vi redis_slave.conf

?? ??? ?從屬服務器設置端口及主服務器端口：

?? ??? ? port 6380
?? ??? ? slaveof localhost 6379

?? ?1.2 啟動主從服務器：
?? ??? ?[root@ractdg3 redis-2.8.4]# src/redis-server redis_master.conf &
