我刚从2.4.7升级到2.4.25 apache（在Ubuntu 14.04上），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，我试图在浏览器中打开网站，它只是加载和加载。
这是我的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）我得到这个：
Upgrade: h2 Connection: Upgrade
我也检查日志（访问和错误），但没有什么。
任何想法，为什么我的网站在启用http2协议后不工作？
如果我在这里testingmywebsite： https ：//tools.keycdn.com/http2-test，它说我的网站支持HTTP / 2.0。
从LogLevel http2:info更改为LogLevel http2:debug ，我在error.log中find了这个：

你需要nghttp来运行mod_http2。
您将以下内容添加到您的configuration中：
<IfModule http2_module> LogLevel http2:info </IfModule>
然后重新启动Apache，并启动不仅仅是一个正常的重启。 在错误日志中你应该看到像这样的细节：
[Wed Jan 04 18:12:07.003271 2016] [http2:info] [pid 12345:tid 123456789012345] mod_http2 (v1.8.3, nghttp2 1.18.0), initializing...

请在你的问题上加上你的版本。
你能看到进入访问日志的请求吗？ 那里是HTTP / 1.1还是HTTP / 2？
另外我想你启用了http2模块？
a2enmod http2
你可以手动启动Apache，并通过以root身份运行以下命令来查看是否有任何错误？
/etc/init.d/apache2 restart
