pour générer un certificat utiliser le script suivant (debian)

a utiliser de cette façon :

script.sh mondomain.com

wget https://raw.githubusercontent.com/diafygi/acme-tiny/master/acme_tiny.py -O /usr/local/bin/acme_tiny.py
mkdir /etc/letsencrypt
chown root:ssl-cert /etc/letsencrypt
chmod 750 /etc/letsencrypt
openssl genrsa -out /etc/letsencrypt/letsencrypt.key 4096
mkdir /etc/letsencrypt/$1
cd /etc/letsencrypt/$1
mkdir -p /home/$1
mkdir -p /home/$1/challenges
openssl genrsa -out $1.key 4096
openssl req -new -sha256 -key $1.key -subj "/CN=$1" -out $1.csr
openssl req -new -sha256 -key $1.key -subj "/" -reqexts SAN -config <(cat /etc/ssl/openssl.cnf <(printf "[SAN]\nsubjectAltName=DNS:$1")) > $1.csr
python /usr/local/bin/acme_tiny.py --account-key /etc/letsencrypt/letsencrypt.key --csr /etc/letsencrypt/$1/$1.csr --acme-dir /home/$1/challenges/ > /etc/letsencrypt/$1.crt

s'assurer que le DNS challenge est dispo

Conf apache2

Alias /.well-known/acme-challenge /srv/www/acme-challenges
<Directory "/srv/www/acme-challenges">
    Options -Indexes
    AllowOverride all
    Require all granted
</Directory>

conf nginx

server {
    server_name www.sysnove.fr;
    …
    location /.well-known/acme-challenge {
        alias /srv/www/acme-challenges/;
        try_files $uri =404;
    }
}

Puis executer le script au debut de cet article tel que script.sh nom-de-domain

/root/certbot-auto certonly --webroot --email wleberre@exemple.com -d sso.exemple1.com -w /var/www/html/ -d domain.exemple1.com -d domaine2.exemple1.com -q --expand
