O servidor MySQL continua desligando

o servidor mysql está sempre desligando, estou usando a DigitalOcean 512 MB de memória e 20GB de disco. Estou executando o WordPress e o iRedMail . Aqui estão os meus registros de erros:

São 512MB de memória e 20GB Os dados não são suficientes para o WordPress, se é o que estou fazendo de errado? Qualquer ajuda seria apreciada.

Dê uma olhada nesta pergunta sobre estouro de pilha (ou este Administradores de Banco de Dados um ), ele trata exatamente da mesma situação. A quantidade de RAM parece pequena demais para o MySQL, você precisará configurar seu servidor de banco de dados e também o seu servidor da Web.

Além disso, se você não tiver uma partição swap, você deve ter uma, se for possível.

Outro conselho: seria melhor fazer essa pergunta em outro membro dos sites do Stack Exchange, já que isso não tem nada a ver com o Ubuntu.
