这篇“redis++怎么编译、安装及使用”文章的知识点大部分人都不太理解，所以小编给大家总结了以下内容，内容详细，步骤清晰，具有一定的借鉴价值，希望大家阅读完这篇文章能有所收获，下面我们一起来看看这篇“redis++怎么编译、安装及使用”文章吧。
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。
