nginx配置访问域名返回404页面，其他页面反代到upstream

 直接上nginx配置文件

　有几点需要注意的地方：

1、upstream反向代理配置

?

1 2 3

upstream whz_t_p {     server 192.168.1.135:80 weight=1 max_fails=1 fail_timeout=30s; }

2、强制https

?

1 2 3

if ($scheme != https) {     rewrite ^(.+)$ https://$host$1 permanent; }

3、指定404页面

?

1 2 3 4

error_page 404 /404.html; location = /404.html {     root /home/web/hw801/whz;  }

4、根据localtion优先级配置 / 显示404页面，其他全部正常

?

1 2 3 4 5 6 7 8

location = / {      return 404; }   location / {      proxy_pass http://whz_t_p;      ...........  }
