Redis master slave + sentry

#Master-slave

testing environment:centos7.4
redis-master:192.168.19.129 vm1
redis-slave1:192.168.19.136 vm4
redis-slave2:192.168.19.135 vm3

1.First, three servers complete the deployment of redis stand-alone.
Edit the redis profile of the master:
[root@redis-master ~]# cd /usr/local/redis-4.0.9
[root@redis-master redis]# vim redis.conf
modify bind为0.0.0.0 protected-mode为no

2.Modify the configuration file of slave1：
[root@redis-slave1 ~]# cd /data/application/redis/
[root@redis-slave1 redis]# vim redis.conf

modify
bind为0.0.0.0
protected-mode为no
Modify slavof as main IP

3.Modify the configuration file of slave2:
[root@redis-slave2 ~]# cd /data/application/redis/
[root@redis-slave2 redis]# vim redis.conf

modify
bind为0.0.0.0
Modify protected-mode as no
Modify slavof as main IP

4.reboot the three redis

Modify sentry
[root@redis-master src]# cd ..
[root@redis-master redis]# vim sentinel.conf
sentinel monitor mymaster 192.168.19.129 6379 2 (The slave indicates the IP address of the master. The master indicates its own IP address)
sentinel down-after-milliseconds mymaster 3000
sentinel failover-timeout mymaster 10000
protected-mode no
Each machine starts sentinel service：
# ./src/redis-sentinel sentinel.conf
