redis++的编译 安装 使用方案

前言

之前给公司作网关，一直想找个牛逼点的C++ 的 或者 C的 redis连接库。 结果很多都不近人意。

常见的是：hiredis 和hirredisvip

hiredis 和hirredisvip 都是最基础的。也没封装什么连接池啊，自动重连啊，那些东西。适合简单的场景。或者你自己手艺好，能自己封装一层好的接口。

后来尝试：cloredis

最后发现：redisplus plus

直到有一天我问同事，他们给我看redis官网推荐的C++的连接库，有好多库。好几页。而平时看的redis中文网推荐的才几个。艾玛。耽误事儿啊。

然后我接触了redisplus plus (redis++）。感觉蛮给力的玩意。

redis++地址

详细的信息可以看他们网站里的介绍。我这里只贴一段代码。
