【问题描述】：

我使用 certbot 成功安装了 Let's Encrypt 的 SSL 证书。我的网站似乎运行没有任何问题。我的服务器是 Apache/2.4.18 上的 Ubuntu 16.04。我安装了 http2 模块，它似乎工作正常。

但是，当我检查我的 Apache error.log 时，我会收到大量这样的消息：

[Fri Sep 08 14:43:05.714366 2017] [http2:info] [pid 2129] (70007)The timeout specified has expired: [client 195.221.155.11:56932] AH02950: h2_session(6): error reading, terminating

我注意到，当我使用浏览器显示我网站的任何页面时，该页面显示良好，但大约 5 分钟后，我在日志中出现此错误消息。

有人知道如何阻止我的 error.log 那样尖叫吗？

【解决方案1】：

将 Apache 升级到更高版本。

例如查看此错误：https://github.com/icing/mod_h2/issues/72

mod_http2 自 2.4.18 以来有很多变化，它只是在 2.4.26 中放弃了“实验”状态。有关详细信息，请参阅此答案：https://serverfault.com/questions/840827/should-we-use-apaches-http2

非常感谢。升级到 apache 2.4.27 时，我遇到了这个错误：[http2:warn] [pid 25095] AH10034: The mpm module (prefork.c) is not supported by mod_http2. The mpm determines how things are processed in your server. HTTP/2 has more demands in this regard and the currently selected mpm will just not do. This is an advisory warning. Your server will continue to work, but the HTTP/2 protocol will be inactive. 所以我禁用了 mpm_prefork 并使用 fastcgi 启用了 mpm_event
