Enabling http/2 in Apache 2.4 does not work（1个答案）
三年前就关门了。
HTTP/2似乎没有运行后，似乎是一个正确的安装。
我运行的是CentOS 7。
我安装了Apache的最新版本，版本httpd-2.4.35-5.el7.x86_64，并一直在尝试让HTTP/2工作。
为此，我看到我们需要运行http2_module。它是活动的并且正在运行。我相信已经通过运行命令httpd -M确认了这一点。http2_module（shared）列在这些模块下面。
接下来我知道要做的是在<VirtualHost ...>标签上添加Protocols h2 h2c http/1.1。我也做过。
最后，我已经弯曲了我的URL，我仍然得到HTTP/1.1。
CURL命令：curl -vsko /dev/null --http2 https://www.thehomepainter.com
来自CURL的简短回应：
GET / HTTP/1.1主机：www.thehomepainter.com用户代理： curl /7.64.0接受：/
〈HTTP/1.1 200正常
来自httpd.conf的部分

Protocols h2 h2c http/1.1
<VirtualHost *:443>
    SSLEngine on
    ServerAdmin ### omitted ###
    ServerName thehomepainter.com
    ServerAlias www.thehomepainter.com
    DocumentRoot /var/www/html/
    Options -Indexes

    ProxyRequests off
    ProxyPreserveHost On
    AllowEncodedSlashes NoDecode

    ProxyPass "/" "http://localhost:3000/"
    ProxyPassReverse "/" "http://localhost:3000/"

    RequestHeader set X-Forwarded-Proto "https"
    RequestHeader set X-Forwarded-Port "443"

    Include /etc/letsencrypt/options-ssl-apache.conf
    SSLCertificateFile ### omitted ###
    SSLCertificateKeyFile ### omitted ###
    SSLCertificateChainFile ### omitted ###

    # i have tried this here as well
    # Protocols h2 h2c http/1.1
</VirtualHost>

Protocols h2 h2c http/1.1
<VirtualHost *:80>
    ServerAdmin support@thedesignguis.com
    ServerName thehomepainter.com
    ServerAlias www.thehomepainter.com
    DocumentRoot /var/www/html
    RewriteEngine on
    RewriteCond %{SERVER_NAME} =thehomepainter.com [OR]
    RewriteCond %{SERVER_NAME} =www.thehomepainter.com
    RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,NE,R=permanent]

    # i have tried this here as well
    # Protocols h2 h2c http/1.1
</VirtualHost>

所以预期的结果是HTTP/2可以工作。然而，它不是，我也不知道为什么。
