# acme-tiny renewal script
|
|
|
|
 is a tiny, auditable script that you can throw on your server to issue and renew Let's Encrypt certifica
|
|
This script allows you to automate certifications with the acme-tiny script.
|
|
|
|
You need the following ressources. For detailed guide see acme-tiny repository.
|
|
* acme-tiny script
|
|
* account.key (registered by letsencrypt)
|
|
* letsencrypt root cert (for creating fillchain cert, automated download)
|
|
* openssl.conf (for certs with multi domains)
|
|
* domain.conf
|
|
|
|
|
|
There is a little script I wrote fast to make my life easier. It is very simple and I guarantee for nothing - use it at your own risk ;).
|
|
|
|
## usage
|
|
|
|
For each domain certificate you need a directory within a domain.conf file.
|
|
The domain.conf file contains the information about the domain.
|
|
|
|
example domain.conf:
|
|
|
|
```
|
|
NAME="domain"
|
|
DOMAINS=(cloud.domain.com domain.net)
|
|
```
|
|
|
|
Then you can run the script with the direcotry.
|
|
|
|
```./renew-cert.sh <directory>```
|
|
|
|
It will create the .csr and .key (4096 bit) file if they don't exists. Then issue a certificate with acme-tiny.py
|
|
|
|
## cronjob examples
|
|
|
|
```
|
|
11 3 5 */2 * user sh /certs/renew_cert.sh domain.com
|
|
11 3 5 */2 * user sh /certs/renew_cert.sh $(< /srv/certs/opt/domains) >> /certs/opt/renew_cert.log
|
|
11 3 5 */2 * user sh /certs/renew_cert.sh $(< /srv/certs/opt/domains) >> /certs/opt/renew_cert.log && docker exec -ti proxy -s nginx reload
|
|
|
|
```
|
|
|
|
## other
|
|
|
|
domains.txt (list of domain directories for run all at once):

|
|
|

openssl.conf (for .csr):
