server1（172.25.2.1） redis主服务器        /home/redis    解压reids
server2（172.25.2.1） redis从服务器1  /home/redis2  解压reids

make MALLOC=libc
make install

server1的配置：redis.conf
bind 172.25.2.1
protected-mode no
port 6379

server2的配置：redis2.conf
bind 172.25.2.1
protected-mode no
port 6389
replicaof 172.25.2.1 6379    

分别启动server1、server2:

redis-cli server1:
set "a1" 999

redis-cli server2:
get "a2"
