主節(jié)點 192.168.232.8:7000/27000
從節(jié)點 192.168.232.9:8000/28000, 9000/29000
redis的程序編譯安裝見單實例安裝文檔
主節(jié)點操作步驟：
groupadd redis && useradd -r -g redis redis
mkdir -p /data/redis-sentinel/7000
配置文件 redis.conf、sentinel.conf
cat /data/redis-sentinel/7000/redis.conf
cat /data/redis-sentinel/7000/sentinel.conf

su - redis -c "/usr/local/redis/bin/redis-server /usr/local/soft/redis-sentinel/9000/redis.conf &"
主節(jié)點sentinel進程啟動：
su - redis -c "/usr/local/bin/redis-sentinel /data/redis-sentinel/7000/sentinel.conf --sentinel &"
從節(jié)點sentinel進程啟動：
