Nel 2017, abbiamo scritto un articolo sulla migrazione a Let's Encrypt da StarSSL e vedrai anche una serie di articoli scritti su problemi e soluzioni di Let's Encrypt. Anche in questo caso, scriviamo come installare il pacchetto Certbot che è uno script che richiede automaticamente i certificati da LetsEncrypt. In questo articolo, ti mostreremo come installare Certbot su CentOS Stream 8. A proposito, quando ho provato a installare su CentOS Stream 8, ho riscontrato il seguente errore:
# dnf install certbot Last metadata expiration check: 3:18:07 ago on Fri 11 Feb 2022 07:32:13 AM IST. No match for argument: certbot Error: Unable to find a match: certbot
Come installare Certbot su CentOS Stream 8
Il Certbot il pacchetto non è disponibile tramite il gestore pacchetti per impostazione predefinita. Dovrai abilitare il EPEL repository per installare Certbot.
Come aggiungere un repository EPEL a CentOS Stream 8

Ora che hai aggiunto il repository EPEL, procedi con l'installazione di certbot.

Questo è tutto! Ora puoi eseguire certbot per ottenere i certificati da Let's Encrypt.
