Thank you for using PHP.
# make
# make install
# cp php.ini-recommended /etc/php.ini
四 、整合apache 与php
# vi /usr/local/apache2/conf/httpd.conf
在最后一行加上：
AddType application/x-httpd-php .php
查找：(设置 WEB 默认文件)
DirectoryIndex index.html
替换为：
DirectoryIndex index.php index.html index.htm //在 WEB 目录不到默认文件，httpd 就会执行 /var/www/error/noindex.html
找到这一段：
# AllowOverride controls what directives may be placed in .htaccess files.
# It can be "All", "None", or any combination of the keywords:
# Options FileInfo AuthConfig Limit
#
AllowOverride none
更改为AllowOverride all
允许apache rewrite
保存httpd.conf，退出。
# /usr/local/apache2/bin/apachectl restart //重启 Apache
五、 测试
vi /usr/local/apache2/htdocs/test.php
新增加下面一行，并保存。
<?php phpinfo(); ?>
# chmod 755 /usr/local/apache2/htdocs/phpinfo.php
用浏览器打开
或者 本机ip/test.php
（如ip为192.168.1.2 则 ）
当看到php页面时表示成功！
