这是我对vcl的配置
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;
}
我已经尝试过任何我找不到的解决方案,这些解决方案都没有改善这种情况,而我对此的了解只是到目前为止。任何帮助将不胜感激。
答案 0 :(得分:1)
在探针设置中,您的超时时间非常短34ms
.probe = {
.url ="/";
.timeout = 34ms;
.interval = 1s;
.window = 10;
.threshold = 8;
}
您确定您的网站加载速度很快吗?如果它没有,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
