这里是我的VCL

backend default { 
.host = "127.0.0.1"; 
.port = "8080"; 
.connect_timeout = 1.5s; 
.first_byte_timeout = 45s; 
.between_bytes_timeout = 30s; 
.probe = { 
    .url ="/"; 
    .timeout = 34ms; 
    .interval = 1s; 
    .window = 10; 
    .threshold = 8; 
    } 
} 

sub vcl_recv 
{ 
    # Set Grace Time to one hour 
    set req.grace = 1h; 
} 

sub vcl_fetch 
{ 
    # Set the TTL for cache object to five minutes 
    set beresp.ttl = 5m; 

    # Set Grace Time to one hour 
    set beresp.grace = 1h; 
} 

我曾尝试任何解决方案,我可以找到没有一个是有好转的情况下,我的这方面的知识只是到目前为止配置。任何帮助,将不胜感激。

您可以发布“netstat -ntlp”执行吗? –

在你探头设置你有一个非常短超时34ms

.probe = { 
    .url ="/"; 
    .timeout = 34ms; 
    .interval = 1s; 
    .window = 10; 
    .threshold = 8; 
    } 

你确定你的站点载入迅速?如果没有,那么Varnish会将该后端主机标记为关闭,因此也会返回错误no backend connection
