以CentOS 5.3 php 2.5.10 nginx 0.8.27为例
wget http://www.php.net/get/php-5.2.10.tar.gz/from/this/mirror
wget http://php-fpm.org/downloads/php-5.2.10-fpm-0.5.13.diff.gz
tar zxvf php-5.2.10.tar.gz
gzip -cd php-5.2.10-fpm-0.5.13.diff.gz | patch -d php-5.2.10 -p1 //如果你用补丁的话先打补丁再改比较妥当，我没检查过补丁有没动这个文件
cd php-5.2.10/
./configure --prefix=...............此处省略N多配置选项
vi main/fopen_wrappers.c
下面代码中两个 add by anxsoft.com 中间的是修改加上去的

然后保存，退出。

make ZEND_EXTRA_LIBS='-liconv'
make install
OK，接下来该干嘛干嘛去～～～

php.in的open_basedir配置为
open_basedir = "/tmp/:/var/tmp/"
