Tentando configurar o Apache na máquina virtual remota. Não consigo acessar da minha máquina

Question

Então eu configurei o httpd e o iptables em uma máquina virtual centos 7 para a qual não tenho acesso físico. Se eu rodar curl http://localhost eu recebo um monte de html, mas se eu digitar o endereço IP da vm (que eu usei para ssh) no chrome, a requisição expira. Deixei o arquivo httpd.conf como está no exemplo, mas modifiquei meu arquivo /etc/sysconfig/iptables como:

# sample configuration for iptables service
# you can edit this manually or use system-config-firewall
# please do not ask us to add additional ports/services to this default configuration
*filter

Para tentar acomodar um servidor FTP e o httpd. Onde devo procurar meu servidor?

Além disso, eu removi firewalld para que não crie um problema.

Answer 1

Parece que você está realmente usando o firewalld. Nesse caso, /etc/sysconfig/iptables é ignorado e o firewalld é configurado usando firewall-cmd .

Apenas dizer ao firewalld para adicionar os serviços que você deseja deve ser suficiente.

firewall-cmd --add-service=http --add-service=https --add-service=ftp

Se você estiver satisfeito com os resultados, poderá salvá-los:

firewall-cmd --runtime-to-permanent

Você pode aprender mais sobre como usar o firewalld no Documentação da Red Hat .
