除了首页能访问，其他路由跳转都是Not Found，然后在域名后面加index.php就能访问，比如http://localhost:81/index.php/admin/，这样就能访问，去掉index.php就不行。

解决方法：
配置中隐藏掉index.php即可
打开nginx的配置文件

server {
        listen       81;
        server_name  www.gohosts.com gohosts.com;
        root   "F:\PHPTutorial\WWW\LvRenJiaJi";
        location / {
            index  index.html index.htm index.php;
            //加上这两句话
            if (-e $request_filename) {
              break;
            }
            if (!-e $request_filename) {
   				rewrite ^/(.*)$ /index.php/$1 last;
   				break;
   	    	}
   	    	
        }
        location ~ \.php(.*)$ {
            fastcgi_pass   127.0.0.1:9000;
            fastcgi_index  index.php;
            fastcgi_split_path_info  ^((?U).+\.php)(/?.+)$;
            fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
            fastcgi_param  PATH_INFO  $fastcgi_path_info;
            fastcgi_param  PATH_TRANSLATED  $document_root$fastcgi_path_info;
            include        fastcgi_params;
        }
}
