六、配置Apache和Php
1、配置/usr/local/etc/apache22/httpd.conf：
# ee /usr/local/etc/apache22/httpd.conf
修改 DirectoryIndex index.html index.htm index index.php index.phps
2、如果你需要修改网站根目录，就修改下面两个地方，下面仅仅是个例子，大家可根据需要自行修改，确保一致即可。
DocumentRoot "/usr/local/www/web"
3、Options Indexes FollowSymLinks
去掉Indexes可以限制浏览你的主页目录
4、加入
AddType application/x-httpd-php .php
AddType application/x-httpd-php-source .phps #可不加
*注意：第二行主要为查看php代码用，加上的话web目录下的所有扩展名为.phps的文件在被浏览器访问时都显示其源代码
5、配置/usr/local/etc/php.ini：
# cd /usr/local/etc/
# cp php.ini-recommended php.ini
# ee php.ini
将short_open_tags = Off 改为On，否则不支持短脚本标记
在error_reporting = E_ALL前面加上;
将error_reporting = E_ALL & ~E_NOTICE前面的;去掉
*将报错信息设置改成去掉notice
upload_max_filesize = 2M
上传最大文件尺寸可根据需要修改
date.timezone = CST
设置服务器时区为中国的时区
