Redis服务端配置、jedis连接池配置模板 rdb定时同步脚本----主要防止主从切换失败时手动启动Master或误重启导致数据丢失 详见：http://tech.lede.com/2017/11/14/rd/server/redistemplate/

jedis.conf

<bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig">
    <property name="maxIdle" value="30" />       //JedisPool最大空闲连接数  
    <property name="minIdle" value="10" />     //JedisPool最小空闲连接数，也即初始化连接数  
    <property name="testOnBorrow" value="false" />   //从JedisPool获取jedis实例时检查连接的有效性，默认是false  
    <property name="testWhileIdle" value="false" />     //表示有一个idle object evitor线程对idle object进行扫描，如果validate失败，此object会被从pool中drop掉  
    <property name="testOnReturn" value="true" />     //将jedis实例归还连接池时检查连接的有效性，默认是false ；test开启太多会影响性能，都不开启异常连接可能会被使用，建议至少开启一个  
    <property name="maxTotal" value="300"/>          //JedisPool最大连接数  
    <property name="maxWaitMillis" value="4000"/>   //从JedisPool获取连接等待毫秒数，超时则抛异常;若blockWhenExhausted为false，该配置项无效  
    <property name="blockWhenExhausted" value="false"/>   //blockWhenExhausted   表示连接耗尽时是否阻塞, false报异常,ture阻塞maxWaitMillis直到超时 ;不配默认是true；建议配置为false
