[Dúvida] Não consigo conectar com o MySQL. Alguém me ajuda?

Boa tarde. Na tela esta aparecendo para vc rodar o comando "" sudo apt-get mysql-cliente-core-5.5 " sem as aspas.... tem hora que o proprio linux ja te da o caminho.

Att., Fernando

É que eu já havia seguido essa instrução dada pelo Linux e não funcionou, mas sigo pesquisando na net para ver se soluciono isso. Fica aparecendo essa mensagem de erro:

Err http://us.archive.ubuntu.com/ubuntu/ precise-updates/main mysql-client-core-5.5 amd64 5.5.24-0ubuntu0.12.04.1

Lucas, o primeiro erro realmente é a falta do mysql-client, como o Fernando citou

Porém, como vc está usando uma versão bem antiga do Ubuntu (os primeiros dois dígitos são o ano de lançamento, nesse caso, 2012) é bem provável que estes repositórios já não existam mais. Aí ocorre o erro do segundo print.

O ideal seria que vc utilizasse uma versão do SO mais atualizada, por segurança e por questões de compatibilidade com novos softwares que vc for utilizar. Mas caso não seja possível, temos algumas alternativas, como utilizar outros repositórios.

• Como root, edite o arquivo /etc/apt/sources.list

• Após salvar o arquivo, execute o comando para atualizar os repositórios:
• apt-get update
• Agora sim, tente instalar o cliente do mysql:
• apt-get install mysql-client-core-5.5

Olá, gente.

Eu consegui identificar o erro, é que não adentrei no mesmo diretório requerido com os arquivos de configuração. Por isso os erros.

Obrigado pela ajuda.
