Script Bash para instalar o site

Question

Primeiro de tudo, desculpe-me se este é o lugar errado para fazer esta pergunta.

Eu fiz um script Bash que instala um backup do DirectAdmin no Apache. As etapas estão funcionando, mas no final, recebo um erro 500 ao abrir o site real.

Passos:
1. Descompacte o arquivo backup.tar.gz
2. remover arquivos desnecessários
3. Solicite detalhes do banco de dados no nome do site
4. Cat para arquivos admin.conf
5. Criar banco de dados e usuário
6. Crie e gere para /etc/apache2/sites-available/website.conf
7. a2ensite e service apache2 reload
8. Criar uma entrada no arquivo de hosts do Windows

Eu rastreei todos os passos para trás e tudo parece funcionar, mas quando eu entro na URL eu recebo um erro 500. Fiz tudo isso sem um script e tudo funciona.

Alguém pode me dizer de onde o erro pode vir? Há algo diferente ao fazer todas essas etapas com um script bash?

EDITAR: Aqui está o script inteiro usado:

#!/bin/bash
clear
tar -zxvf backup.tar.gz
sudo cp -R ./domains/*/public_html/* ./
sudo cp ./backup/*.sql ./
rm -rf ./backup ./domains
rm backup.tar.gz
sudo chmod 775 ./config.php

Quando fiz um backup do DirectAdmin no site www.example.com e usei este site no meu script, tudo foi como deveria, mas ao digitar o URL em um navegador, recebo o erro 500.

Os logs do Apache estão vazios.

Ah, você precisa usar ip_conntrack , faça o seguinte:

1. modprobe ip_conntrack

2. obter lista de variáveis de sysctl com sysctl -a |grep -i conn :
   a saída é ":
   

   net.netfilter.nf_conntrack_acct = 0
   net.netfilter.nf_conntrack_buckets = 65536
   net.netfilter.nf_conntrack_checksum = 1
   net.netfilter.nf_conntrack_count = 116
   net.netfilter.nf_conntrack_events = 1
   net.netfilter.nf_conntrack_expect_max = 1024
   net.netfilter.nf_conntrack_generic_timeout = 600
   net.netfilter.nf_conntrack_helper = 0
   net.netfilter.nf_conntrack_icmp_timeout = 30
   net.netfilter.nf_conntrack_log_invalid = 0
   net.netfilter.nf_conntrack_max = 262144
   net.netfilter.nf_conntrack_tcp_be_liberal = 0
   net.netfilter.nf_conntrack_tcp_loose = 1
   net.netfilter.nf_conntrack_tcp_max_retrans = 3
   net.netfilter.nf_conntrack_tcp_timeout_close = 10
   net.netfilter.nf_conntrack_tcp_timeout_close_wait = 60
   net.netfilter.nf_conntrack_tcp_timeout_established = 432000
   net.netfilter.nf_conntrack_tcp_timeout_fin_wait = 120
   net.netfilter.nf_conntrack_tcp_timeout_last_ack = 30
   net.netfilter.nf_conntrack_tcp_timeout_max_retrans = 300
   net.netfilter.nf_conntrack_tcp_timeout_syn_recv = 60
   net.netfilter.nf_conntrack_tcp_timeout_syn_sent = 120
   net.netfilter.nf_conntrack_tcp_timeout_time_wait = 120
   net.netfilter.nf_conntrack_tcp_timeout_unacknowledged = 300
   net.netfilter.nf_conntrack_timestamp = 0
   net.netfilter.nf_conntrack_udp_timeout = 30
   net.netfilter.nf_conntrack_udp_timeout_stream = 180
   net.nf_conntrack_max = 262144
   

3. altere net.ipv4.netfilter.ip_conntrack_max varibale.

4. armazenar em arquivo.
