一，phpize的好处
什么时候我们要用phpize呢？我们在安装php时：
./configure --prefix=/apps/product/php --with-config-file-path=/apps/product/php/etc \--with-iconv-dir --with-freetype-dir --with-png-dir --with-zlib --with-libxml-dir=/usr \--enable-xml --enable-discard-path --enable-safe-mode --enable-bcmath \--enable-shmop --enable-sysvsem --enable-inline-optimization --with-curl \--with-curlwrappers --enable-mbregex --enable-fastcgi --enable-fpm \
后面根的参数是我们要的模块，但是随着工作的需要，我们还要在加些模块，又不想重新编译php，这些我们就可以用phpize了。
二，安装php模块
下面我以gd模块安装为例子：
cd /apps/product/php-5.6.10/ext/gd #ext目录下面放的是php的模块库/apps/product/php5/bin/phpize#确定php-config文件是否存在，调用php-config，安装后.so文件会自动放到extension_dir里面./configure --enable-gd --with-php-config=/apps/product/php5/bin/php-configmake && make install
安装完后会有这样的东西
See any operating system documentation about shared libraries formore information, such as the ld(1) and ld.so(8) manual pages.----------------------------------------------------------------------Build complete.Don't forget to run 'make test'.Installing shared extensions: /app/product/php5/lib/php/extensions/no-debug-non-zts-20060613/
三，查看.so文件，以及修改php.ini
cd /app/product/php5/lib/php/extensions/no-debug-non-zts-20060613/ls -al |grep gd-rwxr-xr-x 1 root root 763334 Feb 9 10:51 gd.sovi /app/product/php5/lib/php.ini在加载模块的地加上一行extension=gd.so
四，重起phpf服务
查看编译的模块：
/apps/product/php5/bin/php -i|grep configure/apps/product/php5/bin/php -m
php 开启openssl扩展：(当时没测试成功，只能重新编译安装了)
