1、程序目录下创建config目录
2、创建3配置文件
一个主节点6381,两个从节点6382和6383，都未设置密码

master-6381.conf

bind 0.0.0.0
port 6381
logfile "6381.log"
dbfilename "dump-6381.rdb"
daemonize yes
rdbcompression yes
requirepass "123456"
masterauth "123456"
slave-read-only no

slave-6382.conf

bind 0.0.0.0
port 6382
logfile "6382.log"
dbfilename "dump-6382.rdb"
daemonize yes
rdbcompression yes
requirepass "123456"
masterauth "123456"
slave-read-only no
slaveof 127.0.0.1 6381

slave-6383.conf

bind 0.0.0.0
port 6383
logfile "6383.log"
dbfilename "dump-6383.rdb"
daemonize yes
rdbcompression yes
requirepass "123456"
masterauth "123456"
slave-read-only no
slaveof 127.0.0.1 6381

3、启动三个节点，先主后从
./redis-server config/master-6381.conf
./redis-server config/slave-6382.conf
./redis-server config/slave-6383.conf
4、验证集群

5、主节点可读写，从节点只可读
./redis-cli -p 6381
-p: 指定端口
