nginx基本域名 端口 IP 的虚拟主机

基于域名

##nginx并发连接数   processes 乘  connection
## worker_processes   服务进程数,一般和cpu 核心一致即可
worker_processes  1;     
events {
 ##一个worker同时服务数量
    worker_connections  1024;
}
http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    keepalive_timeout  65;
  ### 加下面这个server 块 禁止 IP访问  
        server {
       listen 80 default;
       server_name _;
       return 403;
}

        server {
        listen       80;
        server_name  www.etiantian.org;
        location / {
            root   html/www;   
            index  index.html index.htm;
        }
   }
    server {
        listen       80;
        server_name  bbs.etiantian.org;
        location / {
            root   html/bbs;
            index  index.html index.htm;
        }
      }
     server {
        listen       80;
        server_name  blog.etiantian.org;
        location / {
            root   html/blog;
            index  index.html index.htm;
        }
     }
}
