\#\#\#1、redis一主二从配置

redis7000.conf

port 7000
    daemonize yes
    protected-mode no
    bind 192.168.1.108
    pidfile /var/run/redis-7000.pid
    logfile /opt/module/redis7000/data/"7000.log"
    dir /opt/module/redis7000/data
    slave-read-only yes

redis7001.conf

port 7001
    daemonize yes
    protected-mode no
    bind 192.168.1.108
    pidfile /var/run/redis-7001.pid
    logfile /opt/module/redis7001/data/"7001.log"
    dir /opt/module/redis7001/data
    slave-read-only yes
    slaveof 127.0.0.1 7000

redis7002.conf

port 7002
    daemonize yes
    protected-mode no
    bind 192.168.1.108
    pidfile /var/run/redis-7002.pid
    logfile /opt/module/redis7002/data/"7002.log"
    dir /opt/module/redis7002/data
    slave-read-only yes
    slaveof 127.0.0.1 7000

\#\#\#2、三台Redis Sentinel 搭建

sentinel26379.conf

port 26379
    
    daemonize yes
    
    logfile /opt/module/redis-sentinel/data/"26379.log"
    
    dir /opt/module/redis-sentinel/data
    
    #sentinel通过主节点执行 info replication 命令来获取从节点信息
    sentinel monitor mymaster 127.0.0.1 7000 2
    
    #如果需要监视多套主从，就配置多个sentinel monitor mymaster2 127.0.0.1 7000 2
    
    sentinel down-after-milliseconds mymaster 30000
    
    sentinel parallel-syncs mymaster 1
    
    sentinel failover-timeout mymaster 180000

启动命令：

redis-sentinel sentinel26379.conf

启动后配置文件:自动发现从节点

port 26379
    
    daemonize yes
    
    logfile "/opt/module/redis-sentinel/data/26379.log"
    
    dir "/opt/module/redis-sentinel/data"
    
    sentinel myid aa12fb6410798bb8fffe99fdbb1602d32c278c0c
    
    sentinel deny-scripts-reconfig yes
    
    sentinel monitor mymaster 127.0.0.1 7000 2
    
    sentinel config-epoch mymaster 0
    # Generated by CONFIG REWRITE
    sentinel leader-epoch mymaster 0
    sentinel known-slave mymaster 127.0.0.1 7001
    sentinel known-slave mymaster 127.0.0.1 7002
    sentinel current-epoch 0

**多了从节点的配置信息。**

其他两个sentinel配置文件：

sentinel26380.conf

port 26380
    
    daemonize yes
    
    logfile "/opt/module/redis-sentinel/data/26380.log"
    
    dir "/opt/module/redis-sentinel/data"
    
    sentinel monitor mymaster 127.0.0.1 7000 2
    
    sentinel down-after-milliseconds mymaster 30000
    
    sentinel parallel-syncs mymaster 1
    
    sentinel failover-timeout mymaster 180000

sentinel26381.conf

port 26381
    
    daemonize yes
    
    logfile "/opt/module/redis-sentinel/data/26381.log"
    
    dir "/opt/module/redis-sentinel/data"
    
    sentinel monitor mymaster 127.0.0.1 7000 2
    
    sentinel down-after-milliseconds mymaster 30000
    
    sentinel parallel-syncs mymaster 1
    
    sentinel failover-timeout mymaster 180000
