在Redis中sentinel集群的搭建和Jedis测试 图文教程[一] 中已经写了Redis中sentinel集群的搭建和测试,这一章主要写Redis中sentinel的Jedis测试。


一般sentinel架构图为至少4台机子测试

xserver.ini为项目工程的配置文件

[Redis]
REDIS_NUMBERS=3
REDIS_SERVER_1=tcp://192.168.0.86:26379
REDIS_SERVER_2=tcp://192.168.0.86:26479
REDIS_SERVER_3=tcp://192.168.0.86:26579
REDIS_MASTER=mymaster
REDIS_PASSWORD=vhreal
REDIS_TIME_OUT=5000
REDIS_DATABASE=0
