[转]DreamHost自己编译PHP,支持采集(allow_url_fopen)

DreamHost 自己编译PHP，支持采集(allow_url_fopen)
第一种方法：
1. 下载 php_update.sh 。如果是PHP5，下载 php5_update.sh；如果是 PHP4，下载 php4_update。下面以php5举例。同时下载 附件中的 .htaccess 文件
更新一下：点这里下载php5_update.sh和htaccess文件，我打包好了。
2. FTP上传文件 php5_update.sh 和 .htaccess 到相应域名的根目录
3. SSH登录到Dreamhost，具体操作参见教程六：使用Dreamhost的Shell
4. 修改文件属性为可执行，并执行
[coolcode]chmod +x php5_update.sh
./php5_update.sh[/coolcode]
5. 增加定时项，每周执行一次 php5_update.sh
[coolcode]crontab -e[/coolcode]
然后输入内容
[coolcode]@weekly /home/your-user-name/your-domain-name/php5-update.sh[/coolcode]
按Ctrl + O保存后，按Ctrl + X退出

众所周知，DH默认是不支持大部分的采集器，因为DH默认PHP的 allow_url_fopen 选项没有打开，这是DH的一个大缺陷。好在DH可以让用户自己编译PHP，打开这些选项。
编译方法：
1. 下载附件中的文件 installscript.sh，将其中的“your.domain.com”替换为你的真实域名，然后上传到你的域名目录中
2. 用shell登陆系统
3. 修改 installscript.sh 的属性为可执行：执行命令 “chmod +x installscript.sh”
4. 执行installscript.sh： ./installscript
5. 编译成功后，修改 .htaccess，使用刚才编译出的php程序来解析php文件；在 .htaccess 中添加如下内容：
[coolcode]AddHandler phpFive .php
Action phpFive /cgi-bin/php.cgi[/coolcode]
6. 修改 php.ini，该文件在 ~/your_domain_name/etc/php5/ 目录下，打开 allow_url_fileopen 选项
installscript.sh源码：
[coolcode]#!/bin/sh
# Script updated 2006-12-25 by Carl McDade (hiveminds.co.uk) to allow memory limit and freetype
# Save the code to a file as *.sh
# Abort on any errors
set -e
