github上面fork了一个老外的脚本，修改了一些bug和功能做的分支版本。支持操作系统ubuntu 12.04，别的系统暂时不支持。

安装方法：

$sudo su -
#apt-get install git-core
#git clone git://github.com/xianglei/easy-hiphop.git
#cd easy-hiphop/hiphop-php
#chmod +x install-no-hhvm.sh
#./install-no-hhvm.sh

install-no-hhvm是不带php vm的版本。可正确安装，install.sh带php vm，但是可能无法正确安装，建议安装不带虚拟机的版本。

安装完成后可执行文件在/home/dev/hiphop-php/src/hphp/hphp，脚本会创建一个链接文件到/usr/bin。所以，装好了直接敲hphp就可以用。如果出现HPHP_HOME未设置的错误，请执行

#source /etc/profile

或者

#export HPHP_HOME=/home/dev/hiphop-php

简单使用说明。

编译单个php文件。

#hphp --keep-tempdir=1 --log=4 test.php

编译一个目录

#hphp --keep-tempdir=1 --log=3 --input-dir=/path/to/your/php/source

编译文件到/tmp文件夹下找。

运行/tmp/hphp_xxxxxx/program -m server -p 8080

然后访问服务器的8080端口，url要输入原文件名。比如你编译单个test.php，需要在url里指定

http://localhost:8080/test.php

编译整个目录，hiphop不能为你指定默认访问文件，所以，即使你是index.php，url里面也要写上，当然也可以用指定默认首页的server参数方式启动。参看facebook wiki。

http://localhost:8080/index.php

hphp --help可以查看全部编译参数说明。
/tmp/hphp_xxxxxx/program --help可以查看全部启动选项。

附一个性能测试结果，ab访问默认url为nginx+php5.3，8080端口为hiphop编译后。

均是100000个request，200个concurrency。试过开到500个concurrency，nginx直接挂了。hiphop还能跑。

nginx 4进程+php4进程ab测试处理请求2000个每秒，响应时间0.48秒。

hiphop 单进程，ab测试处理请求3700个每秒，响应时间0.26秒。

无论是请求数还是响应时间都大大提高。

运行参数可参看facebook官方wiki
