Guide avec boisvert.info., plusieurs étapes

Commandes à faire sur un portable:

sebhtml@prometheus# xyz

Commandes à faire sur le serveur avec l'utilisateur root (dans mon cas, boisvert.info, un VPS (Virtual Private Server) chez OVH):

root@vps217173$ xyz

01. Vérifier que nginx roule

root@vps217173:~# systemctl|grep nginx
nginx.service                                                                               loaded active running   A high performance web server and a reverse proxy server         

02. Vérifier le système d'exploitation

root@vps217173:~# lsb_release -a 2>/dev/null|grep Desc
Description:	Debian GNU/Linux 9.9 (stretch)

03. Aller sur https://certbot.eff.org/

sebhtml@prometheus:~$ firefox https://certbot.eff.org/

et choisir I'm using “Nginx” on “Debian 9 (stretch)”

04. Ajouter stretch-backport

root@vps217173:~# echo "deb http://deb.debian.org/debian stretch-backports main" \
        > /etc/apt/sources.list.d/stretch-backports.list
root@vps217173:~# apt update -y

05. Installer les trucs recommendés de certbot

root@vps217173:~# apt-get install \
                certbot python-certbot-nginx -t stretch-backports

06. Installer le plugin certbot DNS

root@vps217173:~# apt install -y python3-certbot-dns-rfc2136 \
         -t stretch-backports 

07. Demander le certificat avec certbot

root@vps217173:~# certbot certonly \
       --preferred-challenges dns --manual -m seb@boisvert.info \
       --agree-tos --eff-email -d boisvert.info

08. Configuration DNS

Après avoir dit Yes, il faut ajouter une entrée TXT dans la zone DNS:

root@vps217173:~# (suite de la commande certbot) 
NOTE: The IP of this machine will be publicly logged as having requested this
certificate. If you're running certbot in manual mode on a machine that is not
your server, please ensure you're okay with that.

Are you OK with your IP being logged?

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

(Y)es/(N)o: Y
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

Please deploy a DNS TXT record under the name
_acme-challenge.boisvert.info with the following value:

YuR89nq85hwQP-wynyhL1MFpZ6p1p8HOwfmzwYcgnqA

09. Déterminer qui a autorité sur le domaine

sebhtml@prometheus:~$ sudo apt install dnsutils 
sebhtml@prometheus:~$ dig boisvert.info SOA|grep -A1 "ANSWER SECTION" 
;; ANSWER SECTION:
boisvert.info.		3575	IN	SOA	ns39.domaincontrol.com. dns.jomax.net. 2019050104 28800 7200 604800 600

10. Sur GoDaddy (DNS), ajouter l'entrée DNS:

Pour mon DNS à moi chez GoDaddy (dans Firefox):

Type: TXT
Host: _acme-challenge
TXT Value: wtvvc_WqkbC04qzNvk0ofqYjHwGzoGa4j_cvjYig-7M
TTL (Time to Live): 1 hour

11. Attendre 5 minutes et vérifier le DNS

Pour laisser l'information DNS se propager dans les tubes de l'Internet.

root@vps217173:~# sleep $((5 * 60))
sebhtml@prometheus:~$ dig _acme-challenge.boisvert.info TXT | grep -A1 "ANSWER SECTION"
;; ANSWER SECTION:
_acme-challenge.boisvert.info. 905 IN	TXT	"YuR89nq85hwQP-wynyhL1MFpZ6p1p8HOwfmzwYcgnqA"

12. Appuyer sur <ENTER>

root@vps217173:~# (suite de la commande certbot) 
Before continuing, verify the record is deployed.

IMPORTANT NOTES:
 - Congratulations! Your certificate and chain have been saved at:
 /etc/letsencrypt/live/boisvert.info/fullchain.pem
 Your key file has been saved at:
 /etc/letsencrypt/live/boisvert.info/privkey.pem
 Your cert will expire on 2019-08-02. To obtain a new or tweaked
 version of this certificate in the future, simply run certbot
 again. To non-interactively renew *all* of your certificates, run
 "certbot renew"

13. Énumérer les certificats Let's Encrypt

root@vps217173:~#  certbot certificates 
Saving debug log to /var/log/letsencrypt/letsencrypt.log

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Found the following certs:
Certificate Name: boisvert.info
  Domains: boisvert.info
  Expiry Date: 2019-08-02 21:57:38+00:00 (VALID: 89 days)
  Certificate Path: /etc/letsencrypt/live/boisvert.info/fullchain.pem

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

14. Ajouter la configuration du certificat dans nginx

Ajouter dans la section “server {” du fichier /etc/nginx/sites-available/default :

      # Let's Encrypt configuration
      listen 443 ssl default_server;
      ssl on;
      ssl_certificate /etc/letsencrypt/live/boisvert.info/fullchain.pem;
      ssl_certificate_key /etc/letsencrypt/live/boisvert.info/privkey.pem;

15. Redémarrer nginx (avec systemctl de systemd)

root@vps217173:~# systemctl restart nginx.service

16. Vérifier que le serveur écoute sur le port TCP/IP 443 (HTTPS)

sebhtml@prometheus:~$  sudo apt  install nmap 
sebhtml@prometheus:~$  nmap boisvert.info -p 443 
Starting Nmap 7.60 ( https://nmap.org ) at 2019-05-04 19:17 EDT

PORT    STATE SERVICE
443/tcp open  https

Nmap done: 1 IP address (1 host up) scanned in 0.07 seconds

17. Vérifier le certificat SSL avec OpenSSL

sebhtml@prometheus:~$  echo | openssl s_client -showcerts \
           -servername boisvert.info -connect boisvert.info:443 \
             2>/dev/null | openssl x509 -inform pem -noout -text
