一、测试环境

master：   127.0.0.1 6379
slave1:    127.0.0.1 6479
slave2:    127.0.0.1 6579
master-sentinel: 127.0.0.1 26379
slave1-sentinel: 127.0.0.1 26479
slave2-sentinel: 127.0.0.1 26579

wget http://download.redis.io/releases/redis-2.8.3.tar.gz
tar ?zxvf redis-2.8.3.tar.gz
cd redis-2.8.3
make;make install(此处可用PREFIX参数将redis安装到其他目录)

三、配置测试环境

―-创建目录：

cd /usr/local
mkdir redis_cluster
mkdir redis_cluster/master_6379
mkdir redis_cluster/slave_6479
mkdir redis_cluster/slave_6579

―-配置redis：
master

cp ?a ?R ?p ~/redis-2.8.3/redis.conf ./redis_cluster/master_6379/
cp ?a ?R ?p ~/redis-2.8.3/sentinel.conf ./redis_cluster/master_6379/6379-sentinel.conf
vi ./redis_cluster/master_6379/redis.conf(将对应配置修改成如下)

daemonize yes  
port 6379  
requirepass vhreal        
masterauth  vhreal  
appendonly no  
save ""  
slave-read-only yes  
vi ./redis_cluster/master_6379/6379-sentinel.conf

port 26379  
sentinel monitor mymaster 192.168.0.86 6379 2  
sentinel auth-pass mymaster vhreal  
sentinel down-after-milliseconds mymaster 30000  
sentinel parallel-syncs mymaster 1  
sentinel failover-timeout mymaster 900000

slave1

cp ?a ?R ?p ~/redis-2.8.3/redis.conf ./redis_cluster/slave_6479/
cp ?a ?R ?p ~/redis-2.8.3/sentinel.conf ./redis_cluster/slave_6479/6479-sentinel.conf
vi ./redis_cluster/slave_6479/redis.conf(将对应配置修改成如下)

daemonize yes  
port 6479  
requirepass vhreal         
masterauth  vhreal  
appendonly no  
save ""  
slave-read-only yes  
slaveof 192.168.0.86 6379  

vi ./redis_cluster/slave_6479/6479-sentinel.conf

port 26479  
sentinel monitor mymaster 192.168.0.86 6379 2  
sentinel auth-pass mymaster vhreal  
sentinel down-after-milliseconds mymaster 30000  
sentinel parallel-syncs mymaster 1  
sentinel failover-timeout mymaster 900000

slave2

cp ?a ?R ?p ~/redis-2.8.3/redis.conf ./redis_cluster/slave_6579/
cp ?a ?R ?p ~/redis-2.8.3/sentinel.conf ./redis_cluster/slave_6579/6579-sentinel.conf
vi ./redis_cluster/slave_6579/redis.conf(将对应配置修改成如下)

daemonize yes  
port 6579  
requirepass vhreal         
masterauth  vhreal  
appendonly no  
save ""  
slave-read-only yes  
slaveof 192.168.0.86 6379  

vi ./redis_cluster/slave_6579/6579-sentinel.conf

port 26579  
sentinel monitor mymaster 192.168.0.86 6379 2  
sentinel auth-pass mymaster vhreal  
sentinel down-after-milliseconds mymaster 30000  
sentinel parallel-syncs mymaster 1  
sentinel failover-timeout mymaster 900000

四、启动集群

注意：首次构建sentinel环境时，必须首先启动master。

启动master和master-sentinel：
redis-server /usr/local/redis_cluster/master-6379/redis.conf
redis-sentinel /usr/local/redis_cluster/master-6379/6379-sentinel.conf

克隆会话，启动slave1和slave1-sentinel：
redis-server /usr/local/redis_cluster/slave-6479/redis.conf
redis-sentinel /usr/local/redis_cluster/slave-6479/6479-sentinel.conf

克隆会话，启动slave2和slave2-sentinel：
redis-server /usr/local/redis_cluster/slave-6579/redis.conf
redis-sentinel /usr/local/redis_cluster/slave-6579/6579-sentinel.conf

查看master的状态：
redis-cli -h 192.168.0.86 -p 6379
这里写图片描述

查看slave的状态：
redis-cli ?h 192.168.0.86 ?p 6479
这里写图片描述

―-场景1：slave宕机
关闭slave1：
查看sentinel状态，查看master的Replication信息，此时只存在一个slave2 6579。
这里写图片描述

―-场景2：slave恢复
重新开启slave1:
