Activation https pour apache2

17 avril 2020

La procédure qui suit est extraite du site suivant :
https://doc.ubuntu-fr.org/tutoriel/securiser_apache2_avec_ssl
Ce qui suit fonctionne pour UBUNTU 18.04 LTS

Sur une installation standard d’apache2, avant de lancer ce qui suit, il faut installer le greffon suivant si celui-ci n’est pas encore installé :
apt install python-certbot-apache

La séquence suivante a fonctionné sans anicroches.

# Activation https pour apache
a2enmod ssl # activation mode ssl
systemctl reload apache2 # relancer apache2
apache2ctl -M | grep ssl # vérification ssl
# greffon à installer si cerbot –apache provoque une erreur
# voir plus haut
apt install python-certbot-apache # installation greffon apache
# installation du créateur de certificats
apt install software-properties-common
add-apt-repository ppa:certbot/certbot
apt update
apt install certbot

1: No redirect – Make no further changes to the webserver configuration.
2: Redirect – Make all requests redirect to secure HTTPS access. Choose this for
new sites, or if you’re confident your site works on HTTPS. You can undo this
change by editing your web server’s configuration.

IMPORTANT NOTES:
– Congratulations! Your certificate and chain have been saved at:
/etc/letsencrypt/live/(le nom de domaine)/fullchain.pem
Your key file has been saved at:
/etc/letsencrypt/live/achc.site/privkey.pem
Your cert will expire on 2020-07-16. To obtain a new or tweaked
version of this certificate in the future, simply run certbot again
with the “certonly” option. To non-interactively renew *all* of
your certificates, run “certbot renew”
– If you like Certbot, please consider supporting our work by:

root@my-server:/etc/apache2#


Cette procédure possède l’inconvénient suivant : le certificat n’est valable que soixante jours.

Remarque importante

La paire de clefs ssl générée permet de protéger un nom de domaine. Si l’on protège
https://www.mon-site.fr ce jeu de clés ne protégera pas https://mon-site.fr
