Ubuntu下php5.5.9降级5.3.x

<span style="font-family: Arial, Helvetica, sans-serif; background-color: rgb(255, 255, 255);">由于PigCMS 官方给的版本对环境是如下要求： </span>

PHP5.4.x with Zend Guard Loader 
Apache 2.2+ 或者 IIS 7.5 ，不使用 Nginx 反向代理的情况下可以支持 Nginx

所以ubuntu下apt-get安装的php5.5.9 不能正确运行，会提示

Zend Guard Run-time support missing!

就需要安装低版本的php 降级安装一直没成功。就重新格式化了服务器，全部重新开启安装

1、下载安装php

wget http://in1.php.net/distributions/php-5.3.29.tar.bz2 tar -xvf php-5.3.29.tar.bz2
cd php-5.3.29
./configure
make
make install

./configure时会报错，

error: xml2-config not found. Please check your libxml2 installation

这时需要重安装libxml2

sudo apt-get install libxml2-dev

然后就可以

./configure

make
make install

但是make install完成会提示

Wrote PEAR system config file at: /usr/local/etc/pear.conf
You may want to add: /usr/local/lib/php to your php.ini include_path
/root/php-5.3.29/build/shtool install -c ext/phar/phar.phar /usr/local/bin
ln -s -f /usr/local/bin/phar.phar /usr/local/bin/phar

但是重启apache php也不生效，直接显示源码，正在解决中
