【中文标题】清漆：大师冥想[关闭]【英文标题】：Varnish: Guru Meditation [closed] 【发布时间】：2012-03-03 22:26:01 【问题描述】：我正在按照 Varnish 3.0.2 文档安装 Varnish
/etc/varnish/default.vcl
backend default
.host = "127.0.0.1";
.port = "80";
.connect_timeout = 600s;
.first_byte_timeout = 600s;
.between_bytes_timeout = 600s;
午餐命令
sudo varnishd -f /etc/varnish/default.vcl -s malloc,200M -T 127.0.0.1:2000 -a 0.0.0.0:8080
文档：https://www.varnish-cache.org/docs/3.0/tutorial/backend_servers.html
我只是想听：8080，但我收到了这个错误：

webtelevideo.com:80 工作正常
【问题讨论】：
Guru Meditation 是对旧 Amiga 系统的致敬。 【参考方案1】：您的后端服务器没有运行。您已配置后端主机“127.0.0.1”，但应该使用“173.245.60.43”（webtelevideo.com 的 IP 地址）。
【讨论】：
清漆日志：11 FetchError c 没有后端连接 按此顺序：127.0.0.1 端口 80 上的服务是否正在运行（执行telnet 127.0.0.1 80）？它是否在 virtualhost webtelevideo.com 上提供正确的（非 503）页面？ Varnish 进程是否允许连接到 80 端口？
您不需要：127.0.0.1:80 上没有运行服务器。这是您的后端服务器（根据您的 vcl）。您通常如何连接到后端服务器？您可以插入 webtelevideo.com 的 IP 地址而不是 127.0.0.1，具体取决于您的路由...
无论如何，你可以尝试设置 .host = "173.245.60.43" 吗？
这被标记为不是答案，老实说，除了两个问题，我也没有看到任何答案。也许你们中的一个人可以编辑解决方案是什么？如果没有，我需要将其转换为问题的 cmets。谢谢。 /cc @user1028100【参考方案2】：
当您看到此错误时，这意味着您的后端大部分情况都已关闭。您在 varnishlog 中的消息证实了这一点：Varnish log: 11 FetchError c no backend connection。
检查您的源服务器是否已启动并且您的 HTTP 服务 (Apache/nginx/other) 是否正在运行。
