Apache 清漆：大师冥想

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

文件：

我只是想在8080上收听，但我得到了以下错误：

webtelevideo.com:80工作正常

后端服务器未运行。您已经配置了后端主机“127.0.0.1”，但应该使用“173.245.60.43”（webtelevideo.com的ip地址）。

当您看到此错误时，这意味着大多数情况下您的后端已关闭。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，您的HTTP服务（Apache/Nginx/other）是否正在运行。

Varnish日志：11 FetchError c无后端连接按此顺序：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上提供适当的（非503）页面？允许Varnish进程连接到端口80吗？不需要：127.0.0.1:80上没有运行的服务器。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，这取决于您的路由…无论如何，您可以尝试设置。host=“173.245.60.43”？这被标记为不是答案，老实说，除了两个问题，我也看不到答案。也许你们中的一个可以编辑解决方案是什么？否则，我需要将此转换为对问题的评论。谢谢/cc@user1028100example.com:80正确工作古鲁冥想是对旧阿米加系统的一种认可。
