我正在为我的应用程序设置 HTTP2，但在 y 浏览器上随机收到 ERR_SSL_PROTOCOL_ERROR。
这只发生在 Google Chrome 浏览器上。在 Firefox 上一切正常。
我正在使用 Let's Encrypth 进行 SSL 加密，一切运行正常。今天启用 HTTP2 后出现了问题。我使用的是 Apache2。我将其更新到 2.4.38 以支持 HTTP2 模块
我尝试了以下操作：
禁用 http2 模块/重新启动 apache2
清除所有浏览器缓存
使用 .htacess 重置 HSTS 标头：
标头设置 Strict-Transport-Security“max-age=0; includeSubDomains;” env=HTTPS
没有结果，这仍然有随机错误。
这是我的虚拟主机配置：
<IfModule mod_ssl.c>
<VirtualHost *:443>
DocumentRoot /var/www/domain/prod/web
ServerName sub.domain.tld
ServerAlias domain
ServerAdmin [email protected]
<Directory "/var/www/domain/prod/web/">
Options FollowSymLinks MultiViews
AllowOverride All
Order allow,deny
Allow from All
</Directory>
ErrorLog /var/www/domain/prod/logs/error.log
LogLevel warn
CustomLog /var/www/domain/prod/logs/access.log combined
ServerSignature On
SSLEngine On
Include /etc/letsencrypt/options-ssl-apache.conf
Protocols h2 http/1.1

</VirtualHost>
</IfModule>
最后更新
我把马丁的答案推崇为最佳答案，因为安装 PHP-FPM 似乎解决了我的问题（没有看到 SSL_ERROR）我做了以下事情：https://www.vultr.com/docs/use-php5-fpm-with-apache-2-on-ubuntu-14-04
但是对于我的一个网站，我在特定页面上收到 500 错误。Apache 错误日志显示：
[Mon Apr 01 14:58:31.844703 2019] [:error] [pid 30434] [client 81.200.189.9:30902] FastCGI: server "/usr/lib/cgi-bin/php5-fcgi" stderr: PHP message: PHP 12. Project->projectFormat() /var/www/jachete/models/Project.php:137
我不太明白错误是什么，有什么想法吗？
更新
禁用“pagespeed”模块后，这里发生了一些有趣的事情，这是我从 error.log 中得到的错误
[Sun Mar 31 16:13:07.090348 2019] [http2:warn] [pid 16845] 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.
[Sun Mar 31 16:13:07.119247 2019] [mpm_prefork:notice] [pid 16845] AH00163: Apache/2.4.38 (Ubuntu) OpenSSL/1.1.1b mpm-itk/2.4.6-01 PHP/5.5.9-1ubuntu4.27 configured -- resuming normal operations
根据https://http2.pro/doc/Apache这是因为 mpm-itk 不支持 http2。因为它只是通知/警告，我认为没有理由导致 SSL_ERROR？

存在权限被拒绝错误，但是当我查看权限时，我得到了这个
drwxr-xr-x 6 www-data www-data 4096 Oct 30 06:34 http,3A/
drwxr-xr-x 3 www-data www-data 4096 Jun 30 2018 https,3A/
我应该为所有用户添加写权限吗？（chmod a+w dir/ -R）？
顺便说一句，即使我禁用 PageSpeed 模块，SSL 错误仍然会发生，所以我猜测上面日志中的错误与我的 SSL 问题无关？
答案1
禁用 mpm_prefork，不要使用 mod_php 使用 PHP FPM 作为快速 CGI 代理，一切都会好起来。
看：https://http2.pro/doc/Apache
我希望这能有所帮助。
