启用 http2 后我的网站无法再运行

我刚刚将 apache（在 Ubuntu 14.04 上）从 升级到2.4.7，2.4.25并且一切正常，之后我启用了 http2 模块并将其插入到我的虚拟主机中：

Protocols h2 http/1.1

之后，我尝试在浏览器中打开网站，但它只是在加载。

以下是我的 SSL 设置：

SSLEngine on
SSLCertificateFile /etc/letsencrypt/live/*/cert.pem
SSLCertificateKeyFile /etc/letsencrypt/live/*/privkey.pem
SSLCertificateChainFile /etc/letsencrypt/live/*/chain.pem

这是我的虚拟主机：

DocumentRoot /home/mywebsite
ServerName mywebsite.com

</Directory>


<IfModule mod_php7.c>
        php_admin_flag allow_url_fopen Off
        php_admin_value open_basedir "/home/mywebsite/:/tmp/"
</IfModule>

<IfModule mod_headers.c>
    Header unset ETag
    Header set X-Frame-Options: deny
    Header set X-XSS-Protection: "1; mode=block"
    Header set X-Content-Type-Options: nosniff
    Header set X-WebKit-CSP: "default-src 'self'"
    Header set X-Permitted-Cross-Domain-Policies: "master-only"
    Header edit Set-Cookie ^(.*)$ $1;HttpOnly;Secure
</IfModule>

<IfModule mod_expires.c>
ExpiresActive On
ExpiresByType image/jpg "access 1 year"
ExpiresByType image/jpeg "access 1 year"
ExpiresByType image/gif "access 1 year"
ExpiresByType image/png "access 1 year"
ExpiresByType text/css "access 1 month"
ExpiresByType text/html "access 1 month"
ExpiresByType application/pdf "access 1 month"
ExpiresByType text/x-javascript "access 1 month"
ExpiresByType application/x-shockwave-flash "access 1 month"
ExpiresByType image/x-icon "access 1 year"
ExpiresDefault "access 1 month"
</IfModule>

如果我尝试从 curl (curl -I hxxps://mywebsite.com) 我会得到这个：

Upgrade: h2
Connection: Upgrade

我也检查了日志（访问和错误），但什么也没有。

有什么想法吗，为什么启用协议后我的网站无法运行http2？

如果我在这里测试我的网站：https://tools.keycdn.com/http2-test，它说我的网站支持 HTTP/2.0。

从 更改为 后LogLevel http2:info，LogLevel http2:debug我在 error.log 中收到此信息：

答案1

您需要 nghttp 来运行 mod_http2。

您可以将以下内容添加到您的配置中：

<IfModule http2_module>
    LogLevel http2:info
</IfModule>

然后以完全停止和启动的方式重新启动 Apache，而不仅仅是正常重启。在错误日志中，您应该看到如下详细信息：

[Wed Jan 04 18:12:07.003271 2016] [http2:info] [pid 12345:tid 123456789012345] mod_http2 (v1.8.3, nghttp2 1.18.0), initializing...
[Wed Jan 04 18:12:07.004910 2016] [mpm_event:notice] [pid 12345:tid 123456789012345] AH00489: Apache/2.4.25 (Unix) OpenSSL/1.0.2j configured -- resuming normal operations

请将上述版本添加到您的问题中。

你能在访问日志中看到请求吗？那里是 HTTP/1.1 还是 HTTP/2？

另外我假设您启用了 http2 模块？

a2enmod http2

您能否手动启动 Apache 并通过以 root 身份运行以下命令来查看是否出现任何错误？：

/etc/init.d/apache2 restart
