突然想往php种增加个模块，可是又不想重新编译php，因为真的比较费时间。
phpize就可以解决这个问题。
cd到php的源代码目录，进入ext。
比如我的工作当做就需要追加mysqli模块，进入mysqli目录。
[vagrant@rs-1 mysqli]$ pwd
/home/vagrant/download/php-5.5.11/ext/mysqli
执行phpize, 咦，报错了！！
[vagrant@rs-1 mysqli]$ phpize
Configuring for:
PHP Api Version: 20121113
Zend Module Api No: 20121212
Zend Extension Api No: 220121212
Cannot find autoconf. Please check your autoconf installation and the
$PHP_AUTOCONF environment variable. Then, rerun this script.
google了下，解决方法如下：安装autoconf
[vagrant@rs-1 mysqli]$ sudo yum install autoconfig
[vagrant@rs-1 mysqli]$ phpize
Configuring for:
PHP Api Version: 20121113
Zend Module Api No: 20121212
Zend Extension Api No: 220121212
发现在当前目录下生成了 configure文件。
执行configure
[vagrant@rs-1 mysqli]$ ./configure --with-php-config=/usr/local/bin/php-config --with-mysqli=/usr/bin/mysql_config
[vagrant@rs-1 mysqli]$ sudo make && sudo make install
[root@rs-1 ext]# ll
