Prérequis système et réseau

Vérifiez que votre système et votre réseau répondent aux exigences minimales avant d'installer l’agent d'automatisation ACME de DigiCert.

L’agent doit être installé sur le même système que celui concerné par les certificats TLS/SSL automatisés.

Avis

If the agent will use a local DigiCert® sensor as proxy, make sure port 48999 is open on the sensor and can be accessed by the agent.

Additional requirements for private on-premises DigiCert ONE users

Users with a private on-premises DigiCert ONE deployment need to install the private DigiCert ONE certificate into the local truststores of any systems that will run agent-based automations.

Below are basic instructions for how to meet these private trust requirements. For more details about how to install and manage the CA certificates in a local truststore, consult the documentation for your operating system version.

Note: These requirements only apply to private on-premises DigiCert ONE users. They do not apply to users of the cloud-hosted DigiCert ONE service.

Windows truststore requirements

To automate certificates on a Windows system via a private on-premises DigiCert ONE server, install the private DigiCert ONE certificate into the Windows truststore as described below.

Active Directory deployment

Refer to this page on the Microsoft website for instructions about how to distribute the DigiCert ONE certificate via Active Directory.

Standalone deployment

To install the DigiCert ONE certificate on a standalone Windows system:

Copy the private DigiCert ONE certificate to the Windows system as a PEM-encoded file (.crt file extension). Note the certificate file location.
Launch the Windows certlm.msc tool as an administrator to manage the certificates on the local machine.
Use the Import action to browse and import the DigiCert ONE certificate file into the list of Trusted Root Certification Authorities > Certificates.

Linux truststore requirements

To automate certificates on a Linux system via a private on-premises DigiCert ONE server, install the private DigiCert ONE certificate into the Linux truststore as follows:

Copy the private DigiCert ONE certificate to the Linux system as a PEM-encoded file (.crt file extension). Note the certificate file location.
Make sure the Linux ca-certificates package is installed. Install it if needed, for example, by running apt-get install ca-certificates or yum install ca-certificates as root.
Copy the .crt file for DigiCert ONE into the CA certificates directory. The location of this directory depends on your Linux distribution and version. See the table below for some possible locations.
Run the command as root to update the local truststore based on the current CA certificate files. The name of this command depends on your Linux distribution and version. See the table below for some possibilities.

Linux distribution	CA certificates directory	Command to update truststore
CentOS/RHEL	/etc/pki/ca-trust/source/anchors/	`update-ca-trust`
SUSE	/usr/share/pki/trust/anchors/	`update-ca-certificates`
Ubuntu	/usr/local/share/ca-certificates/	`update-ca-certificates`
