启动redis节点
redis-server /etc/redis_6379.conf &
redis-server /etc/redis_6380.conf &
redis-server /etc/redis_6381.conf &

启动sentinel节点
redis-sentinel /etc/redis_sentinel_26379.conf &
redis-sentinel /etc/redis_sentinel_26380.conf &
redis-sentinel /etc/redis_sentinel_26381.conf &

或者也可以使用此命令
redis-server /etc/redis_sentinel_26379.conf --sentinel &
redis-server /etc/redis_sentinel_26380.conf --sentinel &
redis-server /etc/redis_sentinel_26381.conf --sentinel &
