redis主从复制+哨兵整合spring
redis整合,采用了spring-data-redis很大程度上方便了我们操作redis的操作.

# redis缓存架构"一主两从三哨兵"模式
# 主: 172.19.105.188 7001
# 从1: 172.19.105.188 7002
# 从2: 172.19.105.188 7003
#
# 哨兵1: 172.19.105.188 27001
# 哨兵2: 172.19.105.188 27002
# 哨兵3: 172.19.105.188 27003
#
#-------------------------------------------------------------------------------
#-------------------------- Matser的ip地址配置 ----------------------------------
# 主机
redis.hostName=172.19.105.188
# 端口号
redis.port=7001
# 连接redis密码
redis.password=
# 客户端超时时间单位是毫秒 默认是2000
redis.timeout=10000
#----------------------- JedisPool的配置 ----------------------------------------
# 最大空闲数
redis.maxIdle=400
# 连接池的最大数据库连接数。设为0表示无限制,控制一个pool可分配多少个jedis实例
redis.maxTotal=1000
# 最大建立连接等待时间。如果超过此时间将接到异常。设为-1表示无限制。
redis.maxWaitMillis=1000
# 连接的最小空闲时间 默认1800000毫秒(30分钟)
redis.minEvictableIdleTimeMillis=300000
# 每次释放连接的最大数目,默认5
redis.numTestsPerEvictionRun=1024
# 逐出扫描的时间间隔(毫秒) 如果为负数,则不运行逐出线程, 默认-1
redis.timeBetweenEvictionRunsMillis=30000
# 是否在从池中取出连接前进行检验,如果检验失败,则从池中去除连接并尝试取出另一个
redis.testOnBorrow=true
# 在空闲时检查有效性, 默认false
redis.testWhileIdle=true
#----------------------------- 哨兵配置 ------------------------------------------
# 哨兵1
redis.sentinel.host1=172.19.105.188
redis.sentinel.port1=27001
# 哨兵2
redis.sentinel.host2=172.19.105.188
redis.sentinel.port2=27002
# 哨兵3
redis.sentinel.host3=172.19.105.188
redis.sentinel.port3=27003
