PHP动态扩展模块（PHP源码包里ext下没有需要的模块的情况下的安装方法）
/usr/local/src/php-7.1.6/ext/
例如我们php已经安装好了，但是发现少了一个模块。但是又不能从新编译php，那么可以用下面这种方式（实际上就是编译出一个.so的文件）：
/usr/local/php/bin/php -m //查看模块

[Zend Modules]下面安装一个redis的模块 在lamp架构下，通常当做一个缓存来用
cd /usr/local/src/
wget https://codeload.github.com/phpredis/phpredis/zip/develop
mv develop phpredis-develop.zip
unzip phpredis-develop.zip
cd phpredis-develop
/usr/local/php/bin/phpize 生成configure文件（此处需生成一个configure模块），注意输出是否报错
./configure --with-php-config=/usr/local/php/bin/php-config 一般只需要加--with就可以了
make && make install
/usr/local/php/bin/php -i |grep extension_dir 查看扩展模块存放目录，我们可以在php.ini中去自定义该路径，但针对这样扩展的模块，我们不用去改他的路径，默认就好
vim /usr/local/php/etc/php.ini 增加一行配置（可以放到文件最后一行）
extension=redis.so

假如在PHP源码包里ext下有需要的模块的情况下的安装方法
（/usr/local/src/php-7.1.6/ext/）
cd /usr/local/src/php-7.1.6/ext/
cd zip cd到需要安装的这个模块目录下
/usr/local/php7/bin/phpize 直接执行，生成.configure
./configure --with-php-config=/usr/local/php7/bin/php-config
make&&make install
