HTTP/2配置未在启用MOD_HTTP2之后运行，并在Conf File中设置的协议

Question

http/2似乎在似乎是适当的安装后运行。

我正在运行Centos 7。

我安装了最新版本的Apache，版本httpd-2.4.35-5.el7.x86_64，并一直在尝试使http/2工作。

为此，我看到我们需要运行http2_module。那是活跃和运行的。我相信通过运行命令httpd -M来确认这一点。http2_module（共享）在这些模块下列出。

我知道要做的接下来是在<VirtualHost ...>标签上方添加Protocols h2 h2c http/1.1。我也做了。

最后，我ed缩了我的URL，我仍然得到HTTP/1.1。
curl命令：curl -vsko /dev/null --http2 https://www.thehomepainter.com

卷发的简短响应：

获取/http/1.1 主持人：www.thehomepainter.com 用户代理：卷曲/7.64.0 接受：/

＆lt;http/1.1 200 ok

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 [e-mail]
    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>

因此，预期的结果是HTTP/2工作。但是，不是，我不知道为什么。

Answer 1

刮过错误日志后，我终于找到了问题。

[http2:warn] [pid 7155] 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.

要解决，我编辑/etc/httpd/conf.modules.d/00-mpm.conf

评论这一行： LoadModule mpm_prefork_module modules/mod_mpm_prefork.so

和不注重底线： LoadModule mpm_event_module modules/mod_mpm_event.so

重新启动apache，然后起作用。
