<p><strong>Enable HTTP/2 Apache Ubuntu</strong> &#8211; Versi default dari Apache yang tersedia di Ubuntu 16.04 belum dilengkapi dengan dukungan HTTP / 2. Namun, untuk beralih dari HTTP/1.1 ke HTTP/2, kita dapat menggunakan versi yang tidak didukung (oleh Ubuntu) tetapi merupakan versi stabil dari apache2 nya itu.</p>
<p>Perbedaan http/1.1 dan http/2 <a href="https://gokulkrishh.github.io/performance/2017/04/30/comparison-of-http-and-http2.html" target="_blank" rel="noopener">Klik Disini</a></p>
<p>Di tutorial ini kita akan melakukan upgrade versi apache terlebih dahulu, oleh karena itu silakan lakukan backup terlebih dahulu kondisi server anda saat ini untuk mencegah adanya suatu kegagalan di tengah jalan ketika proses enable HTTP/2</p>
<h3><span style="color: #0000ff;">Upgrade Apache2</span></h3>
<p>Tambahkan repository external apache terlebih dahulu</p>
<pre># <span style="color: #ff0000;">sudo add-apt-repository ppa:ondrej/apache2</span></pre>
<p>Selanjutnya update repository dan upgrade versi apache2 nya</p>
<pre># <span style="color: #ff0000;">apt update && apt upgrade</span></pre>
<p>Pastikan apache sudah versi terbaru</p>
<pre># <span style="color: #ff0000;">apache2 -v</span> 
Server version: Apache/2.4.33 (Ubuntu) 
Server built: 2018-03-27T10:59:34</pre>
<h3><span style="color: #ff0000;">Set Apache agar Menggunakan PHP FastCGI</span></h3>
<p>Install PHP FastGI module untuk PHP 7.0</p>
<pre># <span style="color: #ff0000;">apt install php7.0-fpm</span></pre>
<p>Enable module proxy_fcgi dan setenvif</p>
<pre># <span style="color: #ff0000;">a2enmod proxy_fcgi setenvif</span></pre>
<p>Enable konfigurasi untuk php7.0-fpm</p>
<pre># <span style="color: #ff0000;">a2enconf php7.0-fpm</span></pre>
<p>Disable module mod_php php7.0</p>
<pre># <span style="color: #ff0000;">a2dismod php7.0</span></pre>
<p>Restart service apache</p>
<pre># <span style="color: #ff0000;">service apache2 restart</span></pre>
<p>Ubah MPM dari prefork menjadi event</p>
<p>Sejak MPM (Multi-Processing Module) prefork tidak sepenuhnya kompatibel dengan HTTP/2, kita harus ubah MPM menjadi event.</p>
<p>Disable MPM Prefork</p>
<pre># <span style="color: #ff0000;">a2dismod mpm_itk</span> 
# <span style="color: #ff0000;">a2dismod mpm_prefork</span></pre>
<p>Enable MPM Event</p>
<pre># <span style="color: #ff0000;">a2enmod mpm_event</span></pre>
<p>Restart apache dan php7.0-fpm</p>
<pre># <span style="color: #ff0000;">service apache2 restart</span> 
# <span style="color: #ff0000;">service php7.0-fpm restart</span></pre>
<h3><span style="color: #0000ff;">Tambahkan Parameter pada file VirtualHost</span></h3>
<p>Tambahkan parameter berikut diantara tag <VirtualHost>&#8230;</VirtualHost> dan di setiap file virtualhost yang aktif. Namun jika ingin semua virtualhost diaktikan menggunakan HTTP/2, tambahkan parameter berikut di file /etc/apache2/apache2.conf</p>
<pre>Protocols h2 h2c http/1.1</pre>
<h3><span style="color: #0000ff;">Enable mod_http2 pada Apache</span></h3>
<pre># <span style="color: #ff0000;">a2enmod http2</span></pre>
<p>Restart service apache2</p>
<pre># <span style="color: #ff0000;">service apache2 restart</span></pre>
