执行`make install`可能会报错，因为ubuntu的apache配置目录中httpd.conf默认是个空文件：    apxs:Error: Activation failed for custom /etc/apache2/httpd.conf file..    apxs:Error: At least one `LoadModule‘ directive already has to exist..    make: *** [install-sapi] Error 1

解决方法：采取欺骗的方法，
在httpd.conf中添加如下注释，假装加在模个模块：
# Dummy LoadModule directive to aid module installations
# LoadModule dummy_module /usr/lib/apache2/modules/mod_dummy.so
之后再make install，通过。

cp php.ini-production /usr/local/php/lib/php.ini   编辑/usr/local/php/lib/php.ini，需要修改几个设置：    expose_php＝Off    upload_max_filesize＝30M    memory_limit = 32M    date.timezone = Asia/Shanghai

　需要手工添加下面一行到/etc/apache2/httpd.conf (并且在前后加上空行)

  LoadModule php5_module /usr/lib/apache2/modules/libphp5.so

  删除/etc/apache2/mods-enabled/php5.load 

  重启apache即可
