| Certificate Authority Security Certificates
| | Install a few helper utils (Make sure Virtualization is enabled in the bios) |
|
| |
| Install the required packages: | |
|
| |
| apt install certbot python3-certbot-dns-ovh
| |
|
| |
| Create an OVH Consumer Key using the following details:
| |
|
| |
| Site: https://api.ovh.com/createToken/?GET=/domain/zone/*&POST=/domain/zone/*&PUT=/domain/zone/*&DELETE=/domain/zone/*/record/*
| |
| Script name: certbot
| |
| Script description: ACME client for security certificates
| |
| Validity: Unlimited
| |
|
| |
|
| You may need to use the OVH "Userid" rather than email - and you need to turn on developer APIs in the account options.
| | apt install qemu-kvm libvirt-clients libvirt-daemon-system |
|
| |
| With the output of the above site, create /etc/letsencrypt/ovh.ini
| |
|
| |
| # OVH API credentials used by Certbot
| |
| dns_ovh_endpoint = ovh-eu
| |
| dns_ovh_application_key = <app_key>
| |
| dns_ovh_application_secret = <app_secret>
| |
| dns_ovh_consumer_key = <consumer_key>
| |
|
| |
| Secure the file:
| |
|
| |
| chmod 600 /etc/letsencrypt/ovh.ini
| |
|
| |
| If the key is ever compromised, revoking it by logging into https://api.ovh.com/console/ and executing:
| |
|
| |
| Check apps with: GET /me/api/application
| |
| Locate correct app: GET /me/api/application/{applicationId}
| |
| Delete the app: DELETE /me/api/application/{applicationId}
| |
|
| |
| Update the configuration file /etc/letsencrypt/cli.ini to use DNS validation at OVH:
| |
|
| |
| # Use DNS authentication at OVH by default
| |
| authenticator = dns-ovh
| |
| dns-ovh-propagation-seconds = 60 | |
| dns-ovh-credentials = /etc/letsencrypt/ovh.ini
| |
|
| |
| To trust Let’s Encrypt certificates:
| |
|
| |
| wget -O /usr/local/share/ca-certificates/isrgrootx1.crt https://letsencrypt.org/certs/isrgrootx1.pem
| |
| wget -O /usr/local/share/ca-certificates/letsencryptauthorityx3.crt https://letsencrypt.org/certs/letsencryptauthorityx3.pem
| |
| update-ca-certificates
| |
|
| |
| Create /etc/letsenrypt/renewal-hooks/deploy/distribute.sh:
| |
| <pre>
| |
| #!/bin/bash
| |
|
| |
|
| declare -A domain
