[在这基础之上模拟的！故障转移测试][Link 1]

String ndoeName = "mymaster"; 是连接sentinel   连接对应的端口号里面的 mymaster 
    (每个sentinel都是mymaster)

3,**test1**就是查看一下 主从复制的 主机从机 在Redis可视化工具里面的 数据库的值是不是相同的！！  
主机可读写，从机只能读！！！不能写  
4,**test2**里是用代码来实现一个故障转移的 监看测试！！！ 循环输出K V  
满足判断的时候 分批输出 100个K！  
![在这里插入图片描述][20200420121811481.png]  
5,我们在后台运行输出的时候 在redis 服务里面 关闭 7002主机！  
运行的时候！！！关闭 7002主机

关闭7002的主机

后台因为主机 关掉！！！所以出错！！但是还是正常运行 **，哨兵检测 ：故障转移**

String ndoeName = "mymaster"; 
    	Set<String> sentinel = new HashSet<String>();
    		sentinel.add("192.168.70.159:26379");
    		sentinel.add("192.168.70.159:26380");
    		sentinel.add("192.168.70.159:26381");
    		
    		JedisSentinelPool sentinelPool = new JedisSentinelPool(ndoeName, sentinel);
    把sentinel的信息放入 JedisSentinelPool池里 ，把端口号集合sentinel也放进去！ 连接Redis可视化工具

### 1，在虚拟机里设置好防火墙！ Rdis可视化工具连接这个设置好的端口！！ 2，在springboot创建 Maven project。 ###

Redis可视化工具连接！！！sentnel 跟Redis端口一样！
