php7安装redis扩展
本站下载：phpredis-php7.zip
unzip phpredis-php7.zip cd phpredis-php7 /usr/local/php7/bin/phpize ./configure --with-php-config=/usr/local/php7/bin/php-config make make install
修改php.ini
vim /usr/local/php7/lib/php.ini
在末尾加上：
extension_dir = "/usr/local/php7/lib/php/extensions/no-debug-non-zts-20151012/" extension = redis.so
重启php，查看phpinfo是否生效
