Certbot Cron Job

This is a tiny Cron Job workaround for certbot nginx issue related in this thread.

Solution

Create and configure manually the certificates at nginx using certonly certbot method; then just set a custom Cron Job using this script.

Step 1

Clone, create or copy the content of this repo in you server.

• /path_to_file/crontab - Cron command task
• /path_to_file/renewssl.sh - Cron Job task
• /path_to_file/renewssl.logs - Cron logging file

Step 2

At crontab file properly configure the path to the files path_to_file.

0 0 1 * * /`path_to_file`/renewssl.sh >> /`path_to_file`/renewssl.logs 2>&1

This taks will run every month 0 0 1 * *, you can set it as you want.

Step 3

Assign execute permission to renewssl.sh.

chmod +x /path_to_file/renewssl.sh

Step 5

Set configuration vars at renewssl.sh.

WEB_SERVICE="nginx"
EMAIL_CERTBOT="[email protected]"
DOMAINS_CERTBOT="-d domain1.com -d domain2.com -d domain3.com"
PORT="80"

Step 6

Setup crontab taks

crontab /path_to_file/crontab

You can edit it using crontab -e.

If you have followed above steps correctly, your cronjob should be ready :)

Debugging

If you want to test if your cron job is working just follow this steps:

Step 0

Update your crontab schedule to run every minute * * * * *. Open and edit your crontab with: crontab -e:

* * * * * /`path_to_file`/renewssl.sh >> /`path_to_file`/renewssl.logs 2>&1

Step 2

Just follow the logging file:

tail /path_to_file/renewssl.logs -f

The output should looks like this:

Step 3
