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，但我收到此错误:

webtelevideo.com:80 工作正常

Answer 1

您的后端服务器没有运行。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)。
