使用phpize增加php模块

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-config

make && make install

安装完后会有这样的东西

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.

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.so

vi  /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)

#进入源码目录:

cd /usr/local/src/php-7.0.14/ext/openssl

[root@supplier-pre01 openssl]# /usr/local/php7/bin/phpize
Cannot find config.m4. 
Make sure that you run '/usr/local/php7/bin/phpize' in the top level source directory of the module

[root@supplier-pre01 openssl]# 

[root@supplier-pre01 openssl]# mv config0.m4 config.m4

[root@supplier-pre01 openssl]# /usr/local/php7/bin/phpize

执行安装后，会提示在某个目录生成.so文件，我生成的位置在/usr/local/php7/lib/php/extensions/no-debug-non-zts-20151012/
打开php.ini,添加下面两句话.

vim /usr/local/php7/etc/php.ini 
extension_dir = "/usr/local/php7/lib/php/extensions/no-debug-non-zts-20151012/"  
extension=openssl.so
