一、模块说明
Redis是一个开源的使用ANSI C语言编写、支持网络、可基于内存亦可持久化的日志型、Key-Value数据库，并提供多种语言的API。
数据持久化有快照方式和日志追加方式，这里使用快照方式，定期将数据保存在dump.rdb文件中
配置主从同步，可让多个slave分摊读请求的负载，也可在master禁用数据持久化，减轻负担，只在slave配置持久化。
二、目录结构
三、代码展示
1、files目录

# as it does use of the /proc filesystem.
# src file is /usr/local/redis/utils/redis_init_script

四、Foreman配置
参考前两编文章
主库参数：
从库参数：
[root@redis-server ~]# redis-cli #连接redis数据库 redis127.0.0.1:6379> >ping #测试连接 >echo test #测试打印 >select 1 #选择数据库0~15 > dbsize #返回当前数据库key数量 > info #获取服务器状态和一些统计信息 > monitor #实时监听并返回redis服务器接收到的所有请求信息 > config get parameter #获取一个redis配置参数信息，*表示全部 > config set parameter value #设置一个redis配置参数信息 > config resetstat #重置INFO命令的统计信息:Keyspace命中数、Keyspace错误数、处理命令数，接收连接数、过期key数等 > debug object key #获取一个key的调试信息 > debug segfault #制造一次服务器当机 > flushdb #删除当前数据库中的所有key > flushall #删除所有数据库中所有key > client list #查看当前所有客户端状态 > shutdown #把数据同步保存到磁盘上，并关闭redis服务 > quit #退出连接

七、程序使用
<?xml version="1.0"?> <configuration> <appSettings> <add key="Redis.ReadWriteHosts" value="10.188.1.40:6379" /> <add key="Redis.ReadOnlyHosts" value="10.188.1.41:6379" /> </appSettings> </configuration>
