写在前面，
1、先创建dir、log 相关文件夹！！！！！！！！！！
2、从库需要设置requirepass 密码，否则主从切换会因为密码丢失而失败
3、主从需要配置，以防主库挂掉，哨兵进行从库切换时，外部链接无法感知真实IP
#机器所在的公网IP或局域网IP
replica-announce-ip 192.168.1.30
#机器所在的公网端口或局域网端口
replica-announce-port 6381

主机

bind 0.0.0.0
port 6379
daemonize yes
protected-mode no
dir /home/redis/conf/data/master

logfile "/home/redis/conf/log/redis_master.log"
requirepass 123456
# 加上这个密码是为了防止主库挂了，重启主库后，无法连接新选举的主库
masterauth 123456

#机器所在的公网IP或局域网IP
replica-announce-ip 192.168.1.30
