Nginx配置

配置多子站点时，例如游戏各种子官网，可以使用通配符或正则表达式的方式配置

server {
    listen       80;
    server_name  *.wan.xoyo.com;
    root   /Users/jiangrongyong/Program/online_code/official_website/guanwang;
    index  index.html index.htm index.php;
    location ~ \.php$ {
        fastcgi_pass   127.0.0.1:9000;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include        fastcgi_params;
    }
}

需要注意的是，PHP在获取$_SERVER["SERVER_NAME"]时，会获取到*.wan.xoyo.com，如果需要获取真实的域名，修改fastcgi_params，把SERVER_NAME的值改成host

fastcgi_param  SERVER_NAME        $host;
