apache - 启用 mod_http2 并在 conf 文件中设置协议后 HTTP/2 配置未运行

问题描述

在似乎正确安装之后，HTTP/2 似乎没有运行。

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，并且一直在尝试让 HTTP/2 正常工作。

为此，我看到我们需要运行 http2_module。那是活跃的和正在运行的。我相信已经通过运行命令确认了这一点httpd -M。http2_module（共享）列在这些模块下。

我知道要做的下一件事是在标签Protocols h2 h2c http/1.1上方添加。<VirtualHost ...>我也这样做了。

最后，我已经将我的 URL 卷曲了，我仍然得到 HTTP/1.1。
卷曲命令：curl -vsko /dev/null --http2 https://www.thehomepainter.com

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

部分来自 httpd.conf

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，事实并非如此，我也不知道为什么。

解决方案

在翻阅错误日志后，我终于找到了问题所在。

[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.

为了解决，我编辑了 /etc/httpd/conf.modules.d/00-mpm.conf

注释掉这一行： LoadModule mpm_prefork_module modules/mod_mpm_prefork.so

并取消注释底线： LoadModule mpm_event_module modules/mod_mpm_event.so

重新启动apache，然后它就可以工作了。
