Je crois que c'est une solution transitoire d'urgence ou quelque chose. En tout cas, ça semble moins déconnant que de les mettre sur github/gitlab/etc. vu qu'on prône l'autonomie et l'autohébergement.

root@web:/home/jmlibs# cp /etc/apache2/sites-available/arn-fai.net.conf /etc/apache2/sites-available/hackstub.netlib.re.conf
root@web:/home/jmlibs# vi /etc/apache2/sites-available/hackstub.netlib.re.conf

Your choices are: 000-default arn-fai.net codelib.re hackstub.netlib.re lg.arn-fai.net netlib.re shaarli.arn-fai.net vps.arn-fai.net
Which site(s) do you want to enable (wildcards ok)?
hackstub.netlib.re
Enabling site hackstub.netlib.re.
To activate the new configuration, you need to run:
  systemctl reload apache2

Test

root@web:/home/jmlibs# apache2ctl configtest
AH00548: NameVirtualHost has no effect and will be removed in the next release /etc/apache2/ports.conf:8

Deux problèmes * on n'a pas mis les fichiers en place * faut configurer letsencrypt

root@web:/home/jmlibs/backups_hackstub.netlib.re# mkdir /var/www/hackstub.netlib.re
root@web:/home/jmlibs/backups_hackstub.netlib.re# cd /var/www/hackstub.netlib.re/

Je commente la partie SSL

Syntax OK
root@web:/var/www/hackstub.netlib.re# apache2ctl restart

Et je peux tester en mettant

/etc/hosts
89.234.141.68 hackstub.netlib.re

Récupération des backups des fichiers

root@web:/var/www/hackstub.netlib.re# mkdir landpage
root@web:/var/www/hackstub.netlib.re/landpage/# wget https://web.archive.org/web/20190227114712/https://hackstub.netlib.re/landpage/ -O index.html

Puis il faut récrire les liens dans index.html et télécharger tout le reste.

Au bout d'un bon moment, on a ça : http://hackstub.netlib.re/landpage/

Comme letsencrypt demande que le DNS soit correct, on commence en http.

root@web:/var/www/hackstub.netlib.re# vi -u /home/jmlibs/.vimrc /etc/apache2/sites-available/hackstub.netlib.re.conf

→ Commenter la section 443

root@web:/var/www/hackstub.netlib.re/landpage# rm ../index.html
root@web:/var/www/hackstub.netlib.re/landpage# cat ../index.php
<?php
header("location: /landpage/");

En fait, contrairement à ce que j'avais compris sur IRC, ce site n'est pas simplement constitué de pages statiques. Il y a aussi des sections /mailman, /blog et /wiki

Je commente les liens vers les sections inexistantes et remplace le lien vers mailman par un lien vers https://forum.arn-fai.net/c/hackstub
