在一些小型服务器上，可能需要部署多个网站来合理利用服务器资源

比如 博客/小官网 等等

在同一个服务器，不同的域名共用80端口

Nginx 只需要在 server里配置好 server_name就好了

配置试例：

http {

   ... 上面省略
	
   # 在码圈 博客
   # 顶级域名 + ww二级域名
    server {
        listen       80;
        server_name  arcinbj.com www.arcinbj.com;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;
        #access_log  "pipe:rollback logs/host.access_log interval=1d baknum=7 maxsize=2G"  main;

        

        error_page  404              /www/error/404.html;

        # redirect server error pages to the static page /50x.html
        #
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
		
	# 强制跳转http到https
        rewrite ^(.*) https://$host$1 permanent;

    }
