How to solve the problem of two missing php extensions during magento2 installation: ext-intl and ext-xsl

问题现象：
[root@localhost magento2]# pwd
/home/wwwroot/default/magento2
[root@localhost magento2]# composer install
Loading composer repositories with package information
Installing dependencies (including require-dev) from lock file
Warning: The lock file is not up to date with the latest changes in composer.json. You may be getting outdated dependencies. Run update to 
update them.
Your requirements could not be resolved to an installable set of packages.
  Problem 1
    - The requested PHP extension ext-intl * is missing from your system. Install or enable PHP's intl extension.
  Problem 2
    - The requested PHP extension ext-xsl * is missing from your system. Install or enable PHP's xsl extension.
解决问题：
进入cd /home/freeman/tools/lnmp1.2-full/src/php-5.6.9/ext/intl/
执行$phpize && ./configure --with-php-c/local/php/bin/php-config && make && make install
在这个configure的过程中会出现错误，安装相应的lib就行。
$yum install libicu-devel -y
$yum install libxslt-devel -y
cd /home/freeman/tools/lnmp1.2-full/src/php-5.6.9/ext/xsl/
$phpize && ./configure --with-php-c/local/php/bin/php-config && make && make install
修改php.ini
$vi /usr/local/php/etc/php.ini
增加：
extension=xsl.so
extension=intl.so
然后重启php服务/etc/init.d/php-fpm restart
再回到/home/wwwroot/magento2下面执行
$composer install
[root@localhost magento2]# composer install
Loading composer repositories with package information
Installing dependencies (including require-dev) from lock file
  - Installing magento/magento-composer-installer (0.1.5)
    Downloading: 100%         
  - Installing braintree/braintree_php (2.39.0)
    Downloading: 100%         
这样就成功了。
