如何使用ubuntu 20.04在apache2上启用http/2

Question

我有运行ubuntu 20.04(apache2(的VPS服务器，正在使用http://1.1，我想升级到http://2

该域已经使用v-hosts进行了配置(并安装了ssl-lets encrypt(。

测试当前协议：

$ curl -I https://my-domain.com
HTTP/1.1 200 OK
Date: Fri, 12 Mar 2021 17:32:01 GMT
Server: Apache/2.4.41 (Ubuntu)
Content-Type: text/html; charset=UTF-8

我升级到http://2:的步骤

1) sudo a2enmod http2
2) add in virtual host (ex: /etc/apache2/sites-enabled/my-domain.com-le-ssl.conf) the line:
Protocols h2 http/1.1     
3) check the config
sudo apache2ctl configtest
4) Restart the web server
sudo systemctl reload apache2

再次测试ptotocol:

$ curl -I https://my-domain.com
HTTP/1.1 200 OK
Date: Fri, 12 Mar 2021 17:57:07 GMT
Server: Apache/2.4.41 (Ubuntu)
Upgrade: h2
Connection: Upgrade
Content-Type: text/html; charset=UTF-8

正如你所看到的，它仍然使用http://1.1

我还从2.4.41更新了apache2；2.4.46…但同样的问题。

我错过了什么？？？

Answer 1

1. 用mpm_event替换mpm_prefork
2. 使用php-fpm(libapache2-mod-fcgid(而不是(libapache2-mod-php(

解决问题。

Answer 2

您可能应该将--http2选项添加到curl命令中
