Aggiornare le versioni di Cumulus Linux
Completare la seguente procedura per aggiornare la versione di Cumulus Linux secondo necessità.
-
Conoscenza di livello intermedio di Linux.
-
Familiarità con la modifica di base del testo, le autorizzazioni dei file UNIX e il monitoraggio dei processi. Sono preinstallati diversi editor di testo, tra cui
vi
e.nano
. -
Accesso a una shell Linux o UNIX. Se si utilizza Windows, utilizzare un ambiente Linux come strumento della riga di comando per interagire con Cumulus Linux.
-
Il requisito della velocità di trasmissione è impostato su 115200 sullo switch della console seriale per l'accesso alla console dello switch NVIDIA SN2100, come segue:
-
115200 baud
-
8 bit di dati
-
1 bit di stop
-
parità: nessuna
-
controllo di flusso: nessuno
-
Tenere presente quanto segue:
|
Ogni volta che Cumulus Linux viene aggiornato, l'intera struttura del file system viene cancellata e ricostruita. La configurazione esistente verrà cancellata. È necessario salvare e registrare la configurazione dello switch prima di aggiornare Cumulus Linux. |
|
La password predefinita per l'account utente cumulus è cumulus. La prima volta che si accede a Cumulus Linux, è necessario modificare questa password predefinita. È necessario aggiornare gli script di automazione prima di installare una nuova immagine. Cumulus Linux offre opzioni della riga di comando per modificare automaticamente la password predefinita durante il processo di installazione. |
