apache中上传.htaccess文件到根目录，内容如下：
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /index.php/$1 [L]
</IfModule>
将上面的内容复制到记事本，另存为.htaccess即可。
typecho在nginx下的rewrite有好多方法
location / {
index index.html index.php;
if (-f $request_filename/index.html){
rewrite (.*) $1/index.html break;
}
if (-f $request_filename/index.php){
rewrite (.*) $1/index.php;
}
if (!-f $request_filename){
rewrite (.*) /index.php;
}
}
windows下的 httpd.ini
