Every three months i must renew my ssl certificates for my subdomains. Because of a lot of subdomains and also different domains it costs a lot of time.
So here’s the solution to renew the letsencrypt certificates automatically with cron:
At the first of every month letsencrypt checks to renew the certificate.
nano /etc/crontab
01 0 1 * * root systemctl stop nginx && /root/letsencrypt/letsencrypt-auto renew && systemctl start nginx
(Insert your letsencrypt path)
nano /etc/letsencrypt/webroot.ini
# webroot.ini general config file rsa-key-size = 4096 email = info@mattionline.de text = True agree-tos = True renew-by-default = True # https://certbot.eff.org/docs/using.html # standalone or webfoot (what you prefer and your configs are set to) authenticator = standalone
