./redis-server /usr/local/redis/conf/6381.conf

查看主从配置

redis-cli -h 127.0.0.1 -port 6379
执行info指令

哨兵

复制redis解压后文件夹中sentinel.conf文件
cp sentinel.conf sentinel-6379.conf
cp sentinel.conf sentinel-6380.conf
cp sentinel.conf sentinel-6381.conf

sentinel-6379.conf

protected-mode no
port 26379
pidfile “/var/run/redis-sentinel-26379.pid”
sentinel monitor mymaster 192.168.56.10 6379 2 #2是选举主节点

./redis-sentinel /usr/local/redis/conf/sentinel-6379.conf

sentinel-6380.conf

protected-mode no
port 26380
pidfile “/var/run/redis-sentinel-26380.pid”
sentinel monitor mymaster 192.168.56.10 6379 2 #2是选举主节点

./redis-sentinel /usr/local/redis/conf/sentinel-6380.conf

sentinel-6381.conf

protected-mode no
port 26380
pidfile “/var/run/redis-sentinel-26381.pid”
sentinel monitor mymaster 192.168.56.10 6379 2 #2是选举主节点

./redis-sentinel /usr/local/redis/conf/sentinel-6381.conf

主节点关闭后在从节点中选举一个作为master
