Atualize versões do Cumulus Linux
Conclua o procedimento a seguir para atualizar sua versão do Cumulus Linux conforme necessário.
-
Conhecimento do Linux de nível intermediário.
-
Familiaridade com edição de texto básica, permissões de arquivo UNIX e monitoramento de processos. Uma variedade de editores de texto são pré-instalados,
vi
incluindo enano
. -
Acesso a um shell Linux ou UNIX. Se você estiver executando o Windows, use um ambiente Linux como sua ferramenta de linha de comando para interagir com o Cumulus Linux.
-
O requisito de taxa de transmissão é definido como 115200 no switch de console serial para acesso ao console de switch NVIDIA SN2100, como segue:
-
115200 baud
-
8 bits de dados
-
1 bit de paragem
-
paridade: nenhuma
-
controle de fluxo: nenhum
-
Tenha em atenção o seguinte:
Cada vez que o Cumulus Linux é atualizado, toda a estrutura do sistema de arquivos é apagada e reconstruída. Sua configuração existente será apagada. Você deve salvar e gravar sua configuração de switch antes de atualizar o Cumulus Linux. |
A senha padrão para a conta de usuário do Cumulus é Cumulus. A primeira vez que você fizer login no Cumulus Linux, você deve alterar essa senha padrão. Você deve atualizar todos os scripts de automação antes de instalar uma nova imagem. O Cumulus Linux fornece opções de linha de comando para alterar a senha padrão automaticamente durante o processo de instalação. |
