我是Turpentine和Varnish的新手，这是我的设置：

nginx->清漆-> nginx-> php5-fpm

当我将Nginx设置为侦听端口80，然后不使用ssl转发到varnish（不是直接在80上运行varnish）时，Varnish可以正常工作，它可以正常工作，缓存的页面速度很快，第一次命中会稍微慢一些（第一次命中大约200ms，已缓存）网页点击大约7-20毫秒）。

然后我尝试用https包裹清漆，首先我用自签名证书对其进行了测试，第一次命中变得缓慢如地狱（30s +，是的，秒，不是ms），缓存命中仍然很快，为7-20ms。来自letsencrypt.org的证书，但无法解决该问题。

我不太了解这里发生了什么，也不知道如何找出导致它如此缓慢的原因。

编辑：在30秒钟的等待时间内，RAM或CPU使用率没有显着增加。

原因很可能是SSL终止或TLS终止代理。

我看到您在Nginx本身中设置了SSL，请考虑使用Pound，或者如果您正在使用负载均衡器来代替Nginx来终止SSL。

如果您要延迟30秒，则很可能是超时：

• https://github.com/nexcess/magento-turpentine/blob/master/app/code/community/Nexcessnet/Turpentine/etc/system.xml#L320

禁用站点搜寻器IP地址后，可以正确设置SSL cookie的本地回送，而不会尝试访问前端。

为Magento + Turpentine设置SSL的更多详细信息：

• https://github.com/nexcess/magento-turpentine/issues/596
• https://github.com/nexcess/magento-turpentine/wiki/SSL_Support
• https://www.digitalocean.com/community/tutorials/how-to-configure-varnish-cache-4-0-with-ssl-termination-on-ubuntu-14-04

您最好采用另一种配置，先
在端口80上使用Varnish，然后在端口443和8000上使用nginx：

        varnish:80 -> nignx:8000 -> php-fpm:9000 
user ->|         |
        nginx:443

还将HTTPS代理到Varnish，您最好添加以下标头：

proxy_set_header X-Forwarded-Proto https;
proxy_set_header X-Forwarded-Port 443;

然后在nginx：8000接收部分，您必须添加真实IP：

set_real_ip_from   127.0.0.1;
real_ip_header     X-Forwarded-For;

否则会一团糟。这样，Varnish：80将始终捕获直接的用户请求，而nginx：443将解密ssl到Varnish，然后Varnish将非缓存的请求发送至nginx：8000

这种配置比较干净，但是真的很难说出为什么您需要30秒以上的时间。
