Eu sou novo no linux / ubuntu, mas eu quero configurar um servidor web apache em uma VM ubuntu. Eu criei uma VM na amazon AWS, instalei o apache. Mas agora não consigo alcançá-lo via navegador. Não tenho certeza se o servidor apache está sendo executado corretamente ou se alguma porta está bloqueada.
Eu verifiquei a versão do apache. Parece ser instalado com "apache -version" e mostra-me uma versão válida e data de instalação.
Eu verifico as portas abertas. Parece que o apache está escutando em algumas portas (3609, 3614, 3615), mas não na porta 80? Que poderia ser o problema? Como pode ser corrigido?
Editar 1: Acutally eu queria adicionar alguns sceenshots, mas eu não posso fazer isso com menos de dez.
Editar 2:
- "sudo /etc/init.d/apache2 status" informa que está sendo executado
- O error.log também parece bom. Diz apenas: "Apache / 2.2.22 (Ubuntu) configurado - retomando as operações normais
Editar 3:
Localhost é acessível a partir do servidor. Então, parece ser um problema de firewall / conexão. Mas o estranho é: eu posso pingar a porta 80 no servidor ip via telnet de fora.
Editar 4:
Posso acessar meu servidor da Web de outra VM da Amazon! Então, o que isso significa: isso é um problema com os grupos de segurança da amazônia?
Eu abordo muitas portas no meu grupo de segurança para fins de teste:

# DefaultType is the default MIME type the server will use for a document
# if it cannot otherwise determine one, such as from filename extensions.
# If your server contains mostly text or HTML documents, "text/plain" is
# a good value. If most of your content is binary, such as applications
# or images, you may want to use "application/octet-stream" instead to
# keep browsers from trying to display binary files as though they are
# text.
#
# It is also possible to omit any default MIME type and let the
# client's browser guess an appropriate action instead. Typically the
# browser will decide based on the file's extension then. In cases
# where no good assumption can be made, letting the default MIME type
# unset is suggested instead of forcing the browser to accept

Na verdade eu não consigo pingar meu host, apenas telnet na porta 80 funciona.
