phpredis扩展安装总结：
PHP扩展安装在[root@iZ254lfyd6nZ lampp]# cd include 目录下
创建一个目录phpredis
下载扩展：wget https://github.com/nicolasff/phpredis/archive/master.tar.gz
解压：[root@iZ254lfyd6nZ phpredis]# tar xvf master.tar.gz
运行：[root@iZ254lfyd6nZ phpredis-master]# /opt/lampp/bin/phpize
安装GCC，避免下面的报错：
[root@iZ254lfyd6nZ phpredis-master]# /opt/lampp/bin/phpize
