redis主機(jī)：10.21.20.131
主端口：6379
從端口：6380
部署過(guò)程：
1. root用戶安裝gcc、gcc-c++
yum install -y gcc gcc-c++
2. tar -xvf redis-3.2.12.tar
mv redis-3.2.12 redis
cd redis
make PREFIX=${HOME}/redis MALLOC=libc install

         3.  cd ~/redis
              mkdir -p conf data/node-6379 data/node-6380
             cp redis.conf conf/node-6379.conf
            配置文件如下部分需要修改：
            bind 0.0.0.0
            dir /home/redis/redis/data/node-6379/ 
            port 6379  
            #masterauth "123456"
            #requirepass "123456"
            pidfile /home/redis/redis/conf/node_6379.pid
        4. 啟動(dòng)redis
            ./redis-server ../conf/node-6379.conf
            ./redis-server ../conf/node-6380.conf
        5. 登錄從庫(kù)
            ./redis-cli -p 6380
             slaveof 10.21.20.131 6379

哨兵主機(jī)：10.21.20.132
端口1：16379
端口2：16380
部署過(guò)程：
1. 安裝reids，同上
2. 哨兵配置文件
#sentinel端口
port 16379
#工作路徑
dir "/home/redis/redis/sentinel1"
#守護(hù)進(jìn)程模式
daemonize yes
protected-mode no

指明日志文件名

                logfile "/home/redis/redis/sentinel1/log/sentinel.log"
            3. 啟動(dòng)哨兵
                ./redis-sentinel ../conf/sentinel_1.conf
                ./redis-sentinel ../conf/sentinel_2.conf
            4. 分別登錄兩個(gè)哨兵執(zhí)行如下命令
                ./redis-cli -p 16379
               sentinel monitor mymaster 10.21.20.131 6379 2
               sentinel set mymaster down-after-milliseconds 5000
               sentinel set mymaster failover-timeout 15000
            5. sentinel monitor mymaster 10.21.20.131 6379 2 //參數(shù)2代表兩個(gè)哨兵同時(shí)認(rèn)為master不可用時(shí)將會(huì)主從切換 ？？
