UBUNTU 16.04 APACHE2开启HTTP2支持

UBUNTU 16.04默认源里的APACHE2没有HTTP2模块,如果启用HTTP2模块一般会报错找不到模块.

a2enmod http2
ERROR: Module http2 does not exist!

所以如果要启用HTTP2模块,需要从源码从头编一个APACHE2.不过编译好的HTTP2模块可以直接拷贝出来使用,所以已经安装过APACHE2了也不需要担心.
首先将源码源加入源列表之中:

vi /etc/apt/sources.list

添加以下:

deb-src http://archive.ubuntu.com/ubuntu/ xenial main universe restricted multiverse
deb-src http://security.ubuntu.com/ubuntu xenial-security main universe restricted multiverse
deb-src http://archive.ubuntu.com/ubuntu/ xenial-updates main universe restricted multiverse

然后刷新源,如果有需要更新的包,顺便升下级:

apt update
apt upgrade

然后安装依赖:

apt install curl devscripts build-essential fakeroot libnghttp2-dev

创建一个工作的编译目录:

cd ~
mkdir apache2
cd apache2

从源里下载APACHE2的源码然后编译:

apt source apache2
apt build-dep apache2
cd apache2-2.4.18
apt install curl devscripts build-essential fakeroot
fakeroot debian/rules binary

将编译的好的HTTP2模块拷贝到APACHE2模块目录中:

cp debian/apache2-bin/usr/lib/apache2/modules/mod_http2.so /usr/lib/apache2/modules/

然后为HTTP2模块编写一个配置文件:

vim /etc/apache2/mods-available/http2.load

在其中写入以下:

LoadModule http2_module /usr/lib/apache2/modules/mod_http2.so

<IfModule http2_module>  
LogLevel http2:info  
</IfModule>

最后启用HTTP2模块:

service apache2 restart
a2enmod http2
service apache2 restart

编辑网站配置文件,加入HTTP2协议:

vim /etc/apache2/sites-enabled/default-ssl.conf

在默认配置文件的SERVERNAME下添加一行:

Protocols h2 http/1.1

如果没有默认配置文件,可参考以下配置文件:

<IfModule mod_ssl.c>  
 <VirtualHost _default_:443>
 ServerAdmin webmaster@localhost
 ServerName your-domain.com
 Protocols h2 http/1.1
 DocumentRoot /var/www/html

 ErrorLog ${APACHE_LOG_DIR}/error.log
 CustomLog ${APACHE_LOG_DIR}/access.log combined

 SSLEngine on

 SSLCertificateFile /etc/ssl/certs/ssl-cert-snakeoil.pem
 SSLCertificateKeyFile /etc/ssl/private/ssl-cert-snakeoil.key

 <FilesMatch ".(cgi|shtml|phtml|php)$">
 SSLOptions +StdEnvVars
 </FilesMatch>
 <Directory /usr/lib/cgi-bin>
 SSLOptions +StdEnvVars
 </Directory>

 </VirtualHost>
</IfModule>

然后还需要将HTTP2协议加入APACHE2配置文件中:

vim /etc/apache2/apache2.conf

加入以下行:

Protocols h2 http/1.1

最后重启APACHE2

service apache2 restart
