定制安装PHP5.2.0和PDFlib7.0.2到Dreamhost主机

为了使用PDFlib扩展，就必须自己定制安装PHP，而不能使用Dreamhost默认安装的PHP5和PHP4。
下面介绍一下我安装的过程。

1）复制接下来这段PHP 5.2.0 安装script，记得把中间第十四行，your.domain.com这个部分用你的域名来代替。

2）登陆到SSH，创建一个新文件叫做installscript。

3）打开installscript，并且把上面修改好的安装script复制进去，保存后退出。

chmod +x installscript

./installscript

AddHandler phpFive .php
Action phpFive /cgi-bin/php.cgi

这时你自己的PHP5就安装好了，你可以看到这样一些文件：
/home/YOUR USERNAME/YOUR DOMAIN HERE/.htaccess
/home/YOUR USERNAME/YOUR DOMAIN HERE/cgi-bin/php.cgi

wget https://www.pdflib.com/binaries/PDFlib/702/PDFlib-7.0.2-Linux-php.tar.gz
tar -xvvzf PDFlib-7.0.2-Linux-php.tar.gz

cp ../../PDFlib-7.0.2-Linux-php/bind/php5/php-520/libpdf_php.so .

cp ../../php5/etc/php5/YOUR DOMAIN HERE/php.ini .

extension_dir = "./"

extension=libpdf_php.so

保存后退出，现在可以在域名目录下用phpinfo()函数来验证安装是否正确了。

PHP5安装script

#!/bin/sh

# Script updated 2006-12-25 by Carl McDade (hiveminds.co.uk) to allow memory limit and freetype
#
# Script updated 2007-11-24 by Andrew (ajmconsulting.net) to allow 3rd wget line to pass
# LIBMCRYPT version information (was set as static download file name previously.)
#
# Save the code to a file as *.sh
# Abort on any errors
#
set -e

# The domain in which to install the PHP CGI script.
export DOMAIN="your.domain.com"

# filesystem.

# Set DISTDIR to somewhere persistent, if you plan to muck around with this
# script and run it several times!
DISTDIR=${HOME}/dist

# Pre-download clean up!!!!
rm -rf $SRCDIR $DISTDIR
