github上面fork了一個老外的指令碼，修改了一些bug和功能做的分支版本。支援作業系統ubuntu 12.04，別的系統暫時不支援。
安裝方法：
$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是不帶php vm的版本。可正確安裝，install.sh帶php vm，但是可能無法正確安裝，建議安裝不帶虛擬機器的版本。
安裝完成後可執行檔案在/home/dev/hiphop-php/src/hphp/hphp，指令碼會建立一個連結檔案到/usr/bin。所以，裝好了直接敲hphp就可以用。如果出現HPHP_HOME未設定的錯誤，請執行
#source /etc/profile
或者
#export HPHP_HOME=/home/dev/hiphop-php
簡單使用說明。
編譯單個php檔案。
#hphp –keep-tempdir=1 –log=4 test.php
編譯一個目錄
#hphp –keep-tempdir=1 –log=3 –input-dir=/path/to/your/php/source

編譯檔案到/tmp資料夾下找。
執行/tmp/hphp_xxxxxx/program -m server -p 8080
然後訪問伺服器的8080埠，url要輸入原檔名。比如你編譯單個test.php，需要在url裡指定
http://localhost:8080/test.php
編譯整個目錄，hiphop不能為你指定預設訪問檔案，所以，即使你是index.php，url裡面也要寫上，當然也可以用指定預設首頁的server引數方式啟動。參看facebook wiki。
http://localhost:8080/index.php
hphp –help可以檢視全部編譯引數說明。
/tmp/hphp_xxxxxx/program –help可以檢視全部啟動選項。
附一個效能測試結果，ab訪問預設url為nginx+php5.3，8080埠為hiphop編譯後。

均是100000個request，200個concurrency。試過開到500個concurrency，nginx直接掛了。hiphop還能跑。
nginx 4程式+php4程式ab測試處理請求2000個每秒，響應時間0.48秒。
hiphop 單程式，ab測試處理請求3700個每秒，響應時間0.26秒。
無論是請求數還是響應時間都大大提高。
