Modificar o hostname no Linux

Para chegar o hostname da sua máquina, execute o seguinte comando:

hostnamectl

Para modificar execute o seguinte comando:

sudo vim /etc/hostname

Para editar, pressione a letra “i”. Após a edição pressione a tecla ESC e depois “:wq”. Se quiser apenas sair, pressione “:q”. Para ignorar a modificação é o “:q!”.

Após executado o comando, reinicie o Apache para ter certeza que tudo estará funcionando perfeitamente:

sudo service apache restart

  1. My brother suggested I would possibly like this blog.

    He used to be totally right. This publish truly made
    my day. You cann’t imagine simply how much time I had
    spent for this information! Thank you!

  2. Hey I know this is off topic but I was wondering if you
    knew of any widgets I could add to my blog that automatically tweet my newest twitter updates.

    I’ve been looking for a plug-in like this for quite some time and was hoping maybe you
    would have some experience with something like this. Please let me know if you run into anything.
    I truly enjoy reading your blog and I look forward to your new updates.
