今天将服务器php版本升到了5.4.4，然后将之前的一个项目改用apache,动态二级转向用.htcaccess，共享一下：
AuthName "yousite Website Coming Soon..." //如果你想给你的网站加个权限访问
AuthType Basic
AuthUserFile D:/xxx/.htpasswd #如果你想设置密码访问 如何生成.htpasswd可以访问 http://www.htaccesstools.com/htpasswd-generator/
#AuthGroupFile /dev/null
require valid-user
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
#Removes access to the system folder by users.
#Additionally this will allow you to create a System.php controller,
#previously this would not have been possible.
#'system' can be replaced if you have renamed your system folder.
RewriteCond %{REQUEST_URI} ^system.*
RewriteRule ^(.*)$ /index.php?/$1 [L]
#When your application folder isn't in the system folder
