Redis下载和安装，可以参考官网https://redis.io/download

$ wget http://download.redis.io/releases/redis-4.0.8.tar.gz

$ tar xzf redis-4.0.8.tar.gz

$ cd redis-4.0.8

$ make

安装后在src目录下启动redis

$ src/redis-server

客户端可以使用命令行来连接和测试

$ src/redis-cli

redis> set foo bar

OK

redis> get foo

PHP安装Redis扩展 (参考http://www.runoob.com/redis/redis-php.html)

这里列出了php的Redis扩展。https://redis.io/clients#php

拿phpredis为例：

https://github.com/phpredis/phpredis

下载和安装：

$ wget https://github.com/phpredis/phpredis/archive/3.1.4.tar.gz

$ cd phpredis-3.1.4 # 进入 phpredis 目录

$ /usr/local/php/bin/phpize # php安装后的路径

$ ./configure --with-php-config=/usr/local/php/bin/php-config

$ make && make install

修改php.ini

vi /usr/local/php/lib/php.ini

更新如下：

extension_dir = "/usr/local/php/lib/php/extensions/no-debug-zts-20090626"

extension=redis.so

安装完成后重启php-fpm 或 apache。查看phpinfo信息，就能看到redis扩展。
