一、安装redis 1主2从集群
略

二、复制sentinel.conf文件到指定目录
修改sentinel.conf配置
port 26379
dir "/tmp"

logfile "/usr/local/redis/logs/sentinel-26379.log"

daemonize yes

sentinel monitor mymaster 10.211.55.7 6379 2

sentinel auth-pass mymaster linlin

sentinel down-after-milliseconds mymaster 15000

sentinel failover-timeout mymaster 120000

sentinel parallel-syncs mymaster 1

发生切换之后执行的一个自定义脚本：如发邮件、vip切换等

sentinel notification-script <script-path>

三、配置sentinel从节点
port 26380

dir "/tmp"

logfile "/usr/local/redis/logs/sentinel-26380.log"

daemonize yes

sentinel monitor mymaster 10.211.55.7 6379 2

sentinel down-after-milliseconds mymaster 15000

sentinel failover-timeout mymaster 120000

sentinel auth-pass mymaster linlin

sentinel config-epoch mymaster 0

发生切换之后执行的一个自定义脚本：如发邮件、vip切换等

sentinel notification-script <script-path>

四、配置2381从节点
port 26381

dir "/tmp"

logfile "/usr/local/redis/logs/sentinel-26381.log"

daemonize yes

sentinel monitor mymaster 10.211.55.7 6379 2

sentinel down-after-milliseconds mymaster 15000

sentinel failover-timeout mymaster 120000

sentinel auth-pass mymaster linlin

sentinel config-epoch mymaster 0

发生切换之后执行的一个自定义脚本：如发邮件、vip切换等

sentinel notification-script <script-path>

五、启动sentinel哨兵
./redis-sentinel ../conf/sentinel-26379.conf
./redis-sentinel ../conf/sentinel-26380.conf
./redis-sentinel ../conf/sentinel-26381.conf

六、查看日志
