<p>Nous allons installer un serveur Web: <strong>Apache</strong>. C'est juste celui que je connais le mieux. <strong>Nginx</strong> est une possible alternative très prisée et guère plus compliquée à mettre en oeuvre.</p>
<pre><code>root@aijan:/etc/bind# apt install apache2
Lecture des listes de paquets... Fait
Construction de l'arbre des dépendances
Lecture des informations d'état... Fait
The following additional packages will be installed:
    apache2-bin apache2-data apache2-utils libapr1 libaprutil1 libaprutil1-dbd-sqlite3 libaprutil1-ldap liblua5.2-0
etc ...
</code></pre>
<p>Test de notre serveur:</p>
<p>C'est bon, voilà une image de la page d'acceuil :</p>
<p><img alt="Le serveur apache" src="../Images/apache.png" /></p>
<p>Ne pas oublier d'ouvrir les ports du firewall: port 80 et 443 en TCP et UDP.</p>
<p>Lignes à rajouter à firewall.sh:</p>
<pre><code>  # HTTP + HTTPS Out
  $IPT -t filter -A OUTPUT -p tcp --dport 80 -j ACCEPT
  $IPT -t filter -A OUTPUT -p tcp --dport 443 -j ACCEPT

  $IP6T -t filter -A OUTPUT -p tcp --dport 80 -j ACCEPT
  $IP6T -t filter -A OUTPUT -p tcp --dport 443 -j ACCEPT

  # HTTP + HTTPS In
  $IPT -t filter -A INPUT -p tcp --dport 80 -j ACCEPT
  $IPT -t filter -A INPUT -p tcp --dport 443 -j ACCEPT

  $IP6T -t filter -A INPUT -p tcp --dport 80 -j ACCEPT

<p>Validez-les avec:</p>

<p>On crée un fichier <strong>index.html</strong> sous chaque répertoire créé:</p>

</code></pre>
<p>Dans le répertoire <strong>/var/www/html/</strong> on lance la commande suivante pour ajuster les droits et propriétaires des fichiers (pour apache et Debian, c'est <strong>www-data</strong>.)</p>
<pre><code>chown -Rv www-data.www-data *
</code></pre>
<p>On relance apache</p>
<pre><code>service apache2 restart
</code></pre>
<p>On teste avec un navigateur.</p>
<ul>
<li>
<p>adresse 1: www.yojik.net</p>
</li>
<li>
<p>adresse 2: yazik.yojik.net</p>
</li>
</ul>
<p>Vous vous apercevrez que la deuxième ne fonctionne pas: il vous faut ajouter le domaine yazik.yojik.net à votre fichier de zone de bind et relancer bind ensuite:</p>
<pre><code>yazik       IN  CNAME   atom.yojik.net.
</code></pre>
<p>Re-testez: tout marche :)</p>
