wget http://pecl.php.net/get/redis-5.2.1.tgz
tar -zxvf redis-5.2.1.tgz
cd redis-5.2.1/
phpize
./configure --with-php-config=/home/work/study/soft/php/bin/php-config
make && make install

修改 php.ini 并加入 extension=redis.so , 然后重启 php-fpm
vim /home/work/study/soft/php/lib/php.ini
pkill -9 php-fpm
php-fpm

<?php //实例化redis $redis = new Redis(); //连接 $redis->connect('127.0.0.1', 6379); //检测是否连接成功 echo "Server is running: " . $redis->ping();

访问脚本，页面中输出 
Server is running: 1 
则说明，已经安装 redis 扩展成功
