Automate SSL Certificate Renewal on Ubuntu

Let’s Encrypt SSL Certificates are valid for 90 days only and it needs to renewed but they do provide renewal command and thus you can  automate the SSL renewal task by creating a cron job. If you don’t know what is cron job, don’t worry just execute the commands, it will take care.

Now to create a new cron job, you need to edit the crontab. For that, run following command as root

sudo crontab -e

Include the following command in one line:

30 5 * * 3 /opt/letsencrypt/certbot-auto renew >> /var/log/le-renew.log
 Here Each line has five time-and-date fields  separated by spaces. The five time-and-date fields are as follows: minute (0-59), hour (0-23, 0 = midnight), day (1-31), month (1-12), weekday (0-6, 0 = Sunday).
Thus you can change the cron job to any time and it will periodically check for renewal at that time.

Save and exit. ( Press Ctrl + X)
