Um subdom\u00ednio \u00e9 uma se\u00e7\u00e3o separada do seu dom\u00ednio principal que funciona como se fosse um site independente, utilizando um prefixo \u00e0 frente do nome do seu dom\u00ednio. Exemplos comuns s\u00e3o blog.seudominio.com<\/em>, shop.seudominio.com<\/em>, ou suporte.seudominio.com<\/em>. \u00c9 poss\u00edvel criar subdom\u00ednios gratuitamente com o seu dom\u00ednio atual, e essa \u00e9 uma maneira pr\u00e1tica de organizar diferentes partes da sua presen\u00e7a online sem precisar registrar um dom\u00ednio totalmente novo.<\/p>\n

Por que usar um subdom\u00ednio?<\/h2>\n

Os subdom\u00ednios permitem manter separados conte\u00fados relacionados, mas distintos, tanto para os visitantes quanto para os mecanismos de busca. Eles s\u00e3o \u00fateis quando uma se\u00e7\u00e3o do seu site tem um objetivo, um p\u00fablico-alvo ou um software pr\u00f3prios. Entre os usos mais comuns est\u00e3o:<\/p>\n

    \n
  • Um blog:<\/strong> blog.yourdomain.com deve ser mantido separado das suas p\u00e1ginas principais de marketing.<\/li>\n
  • Uma loja virtual:<\/strong> shop.yourdomain.com, que utiliza um software de com\u00e9rcio eletr\u00f4nico.<\/li>\n
  • Uma central de ajuda:<\/strong> support.seudominio.com ou docs.seudominio.com.<\/li>\n
  • Um ambiente de teste ou de prepara\u00e7\u00e3o:<\/strong> dev.yourdomain.com para testar altera\u00e7\u00f5es com seguran\u00e7a.<\/li>\n<\/ul>\n

    Como um subdom\u00ednio pode hospedar seu pr\u00f3prio aplicativo, voc\u00ea pode, por exemplo, hospedar o WordPress no seu dom\u00ednio principal e uma ferramenta totalmente diferente em um subdom\u00ednio.<\/p>\n

    Como criar um subdom\u00ednio<\/h2>\n

    Criar um subdom\u00ednio leva apenas um minuto no seu painel de controle. Os nomes exatos variam um pouco entre o DirectAdmin e o cPanel, mas o procedimento \u00e9 o mesmo:<\/p>\n

      \n
    • Fa\u00e7a login no seu painel de controle.<\/li>\n
    • Abra o Subdom\u00ednios<\/strong> ou Dom\u00ednios<\/strong> se\u00e7\u00e3o.<\/li>\n
    • Digite o prefixo desejado, como, por exemplo, blog<\/em>.<\/li>\n
    • Confirme a pasta (raiz de documentos) onde os arquivos ficar\u00e3o armazenados.<\/li>\n
    • Salve, e o subdom\u00ednio ser\u00e1 criado.<\/li>\n<\/ul>\n

      Seu painel de controle adiciona automaticamente o registro DNS necess\u00e1rio para que o subdom\u00ednio seja resolvido; portanto, normalmente n\u00e3o h\u00e1 nada mais a ser configurado.<\/p>\n

      Adicionando conte\u00fado ao seu subdom\u00ednio<\/h2>\n

      Cada subdom\u00ednio possui sua pr\u00f3pria pasta no servidor. Para configur\u00e1-lo, envie arquivos para essa pasta ou instale um aplicativo nela. Se voc\u00ea quiser o WordPress no seu subdom\u00ednio, pode usar um instalador de um clique e simplesmente escolher o subdom\u00ednio como local de instala\u00e7\u00e3o. Lembre-se de habilitar o SSL para o subdom\u00ednio, para que ele tamb\u00e9m seja carregado de forma segura, com o \u00edcone do cadeado.<\/p>\n

      Subdom\u00ednio x subpasta<\/h2>\n

      Voc\u00ea pode estar em d\u00favida se deve usar um subdom\u00ednio (blog.seudominio.com) ou uma subpasta (seudominio.com\/blog). Ambas as op\u00e7\u00f5es s\u00e3o v\u00e1lidas. Uma subpasta mant\u00e9m tudo dentro de um \u00fanico site e costuma ser mais simples para o SEO, enquanto um subdom\u00ednio \u00e9 mais adequado quando a se\u00e7\u00e3o precisa funcionar de forma independente ou utilizar um software diferente. Escolha com base no grau de independ\u00eancia que a se\u00e7\u00e3o precisa ter.<\/p>\n

      Solu\u00e7\u00e3o de problemas<\/h2>\n
        \n
      • O subdom\u00ednio n\u00e3o est\u00e1 carregando:<\/strong> Aguarde um pouco at\u00e9 que o registro DNS entre em vigor.<\/li>\n
      • Sem cadeado:<\/strong> emitir ou renovar o certificado SSL do subdom\u00ednio.<\/li>\n
      • \u00c9 exibido um conte\u00fado incorreto:<\/strong> Verifique se os arquivos est\u00e3o na pasta do pr\u00f3prio subdom\u00ednio.<\/li>\n<\/ul>\n
