Nginx虚拟主机以及访问规则

server {
    listen 88;
    server_name www.ceshi.com;
    location /www {
      root /data/;                                   root是当匹配www的时候到/data/www/下找index.html     
                                                         如果data下没有www目录就会报错
      index index.html;

}

}
server {
    listen 88;
    server_name blog.ceshi.com;
    location /www {
      alias /data/html/;                              alias是当匹配www的时候到/data/html/找index.html
      index index.html;
