将IPv4与IPv6结合使用时，为什么我的服务器速度慢且SSL不匹配

时间：2018-09-17 06:47:18

标签： nginx dns ssl-certificate ipv6 http2

我正在使用带有HTTP2和PHP 7.2.7的Ubuntu 18.04.1 Nginx 1.14.0设置新服务器，这是我尝试设置同时启用IPv4和IPv6的第一台服务器。一切正常，直到我测试了缺少很多图像的页面。服务器似乎永远需要意识到它们丢失并响应http请求。一些丢失的文件的HTTP状态为“ 502错误的网关”。是DNS问题导致这些延迟和502错误，我应该在设置中进行哪些更改？

编辑：这里可能有很多不必要的信息，但是由于服务器响应速度太慢的原因尚不清楚，因此其中一些可能很重要。

php脚本应该不是问题，我的旧服务器具有完全相同的页面，加载速度非常快。

区域文件同时记录了IPv4和IPv6。

编辑：下面的整个DNS理论可能不是原因，请参见：Why does this nginx server redirect to a wrong domain?。 服务器重定向到错误的域。当强制nginx服务器仅侦听IPv4并浏览到server1.eu时，存在SSL证书不匹配（仅对server2.eu有效），在强制接受证书后，存在301重定向到server2.eu 现在，当我从启用站点的服务器中删除服务器“ server2.eu”并重新加载nginx时，不会发生SSL证书不匹配和重定向。从启用站点的服务器“ server2.eu”中删除，并在nginx服务器设置中禁用server1.eu服务器IPv4，浏览到server1.eu时导致“与服务器无连接”，而从站点中删除服务器“ server2.eu”启用，并且从nginx服务器设置禁用了server1.eu服务器IPv6，这将导致服务器运行缓慢。然后我再次还原server2.eu服务器，并从nginx服务器设置中禁用server1.eu服务器IPv4，结果：SSL证书不匹配（仅对server2.eu有效），并在强制接受证书301后重定向到server2.eu禁用server1.eu服务器nginx服务器设置中的IPv6导致服务器速度很快，解决了“服务器速度慢”的问题，因此server1.eu依赖错误的服务器才能正常工作。同时，IPv6地址[2a03：b0c0：0：1010 :: 190：6001]仍重定向到server1.eu

编辑：服务器中的一个区别是旧的具有http1.1，而新的具有http2。禁用http2可解决超长加载和502错误。页面的加载时间仍比旧服务器长（6.40 vs 3.18秒）

当增加/etc/php/7.2/fpm/pool.d/www.conf中的设置时，错误消失并且加载时间仍然很长：8.4秒和3,16秒，但接近旧版本服务器：

pm.max_children = 100
pm.start_servers = 20
pm.min_spare_servers = 20
pm.max_spare_servers = 30

旧服务器仅支持IPv4，HTTP 1.1，可用内存较少，PHP版本5.5.9-1 Ubuntu 14.04.5 LTS和Nginx 1.4.6。它的设置是：

pm.max_children = 5
pm.start_servers = 2
pm.min_spare_servers = 1
pm.max_spare_servers = 3

主机文件可能是一个问题，但是，如果一起清空主机文件，则问题仍然存在。这里是内容：

127.0.0.1 localhost

答案 0 :(得分：1)

这个问题有很多东西，甚至不清楚要问什么-所有那些非服务器日志404错误对于大多数读者来说意义不大，而且，当然，我从未听说过仅仅存在对图像请求有任何影响的IPv6突然返回404错误。

您已经提供了find /etc/nginx/{conf.d,sites-enabled}和find /etc/nginx/{conf.d,sites-enabled} | xargs fgrep listen，并且那里并没有什么特别之处-似乎每个非IPv4 listen都带有一个IPv6 { {1}}。 http://nginx.org/r/listen。

下一步，恕我直言，将是单独使用curl直接重现错误，包括使用listen，-v和-4标志的某种组合来查看这是怎么回事。绝对要确保您是从实际遇到错误的客户端主机上进行操作的；整个问题也可能源于客户端方面的问题。

-6的另一个有用功能是，如果您认为自己的问题与DNS有关，则可以使用域映射。如果您将curl选项与-v一起使用，您已经可以看到请求将转到哪个IP地址（这很容易揭示旧的DNS，除非它仅在浏览器中是旧的）。下一步可能是使用curl选项（例如--resolve或类似的选项）覆盖IP地址。

最后，如果您仍然仅通过IPv6（--resolve test.vuyk.eu:443:2a03:b0c0:0:1010::190:6001）而不是通过IPv4（-6）经历延迟和失败，则问题可能与客户端上的IPv6连接有关；具体来说，如果您的连接通过隧道或6号隧道，则MTU发现可能会沿着路径中断；在Linux上，您可以尝试使用-4进行故障排除，它会沿路径打印tracepath值。

FWIIW，我尝试通过TMo US通过IPv6本机连接访问您的站点，对于IPv6的MTU为1500（实际上，它们通过IPv6隧道传输IPv4，因此，从T-Mo US来看，IPv4 MTU为1472）理解），我看不到任何明显的问题（据我所知，您目前确实为test.vuyk.eu发布了IPv6记录）。也许整个问题是由于设置中客户端的DNS缓存过时？您在服务器日志中看到的是在客户端中看到的所有404错误？！
