  5. Remover ISO da VM:

    • VM ā†’ Hardware ā†’ CD/DVD ā†’ Edit ā†’ Do not use any media

āš™ļø ConfiguraĆ§Ć£o Inicial

1. Primeiro Acesso

ApĆ³s reboot, o servidor exibe:

Welcome to the Proxmox Backup Server. Please use your web browser to
configure this server - connect to:

  https://192.168.1.30:8007/

Login:

šŸ” ConfiguraĆ§Ć£o de Certificados SSL

OpĆ§Ć£o 1: Certificado Auto-Assinado (PadrĆ£o)

Por defeito, PBS usa certificado auto-assinado.

Renovar certificado:

# SSH para o PBS
ssh root@192.168.1.30

# Gerar novo certificado
proxmox-backup-manager cert generate-self-signed

# Reiniciar serviƧo
systemctl restart proxmox-backup-proxy

OpĆ§Ć£o 2: Letā€™s Encrypt (Recomendado para ProduĆ§Ć£o)

Se PBS for acessĆ­vel via domĆ­nio pĆŗblico:

# Configurar ACME account
proxmox-backup-manager acme account register \
  --contact admin@fsociety.pt \
  default

# Configurar domain
proxmox-backup-manager acme domain add \
  --domain pbs.fsociety.pt

# Obter certificado
proxmox-backup-manager acme cert order

# Certificado serĆ” renovado automaticamente

OpĆ§Ć£o 3: Certificado Personalizado

# Copiar certificado e chave
scp cert.pem root@192.168.1.30:/etc/proxmox-backup/proxy.pem
scp key.pem root@192.168.1.30:/etc/proxmox-backup/proxy.key

# Definir permissƵes
chmod 600 /etc/proxmox-backup/proxy.key
chmod 644 /etc/proxmox-backup/proxy.pem

# Reiniciar serviƧo
systemctl restart proxmox-backup-proxy

Ver Fingerprint do Certificado

NecessƔrio para adicionar PBS ao Proxmox VE:

# Via CLI
proxmox-backup-manager cert info

# SaĆ­da:
# subject: CN=pbs.fsociety.pt
# issuer: CN=Proxmox Backup Server
# notBefore: YYYY-MM-DD HH:MM:SS
# notAfter: YYYY-MM-DD HH:MM:SS
# Fingerprint (sha256): XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX

# Copiar o Fingerprint para usar no Proxmox VE

šŸ› ļø ConfiguraƧƵes PĆ³s-InstalaĆ§Ć£o

1. Atualizar Sistema

# SSH para o PBS
ssh root@192.168.1.30

# Atualizar lista de pacotes
apt update

# Atualizar sistema
apt dist-upgrade -y

# Reiniciar se necessƔrio
reboot

2. Configurar NTP

# Verificar sincronizaĆ§Ć£o de tempo
timedatectl status

# Configurar NTP
nano /etc/systemd/timesyncd.conf

# Adicionar:
[Time]
NTP=pt.pool.ntp.org
FallbackNTP=0.debian.pool.ntp.org

# Reiniciar serviƧo
systemctl restart systemd-timesyncd

# Verificar
timedatectl show-timesync --all

3. Configurar NotificaƧƵes Email

# Configurar Postfix
dpkg-reconfigure postfix

# Tipo: Satellite system
# Smarthost: [servidor SMTP]

# Testar
echo "Teste PBS" | mail -s "Teste PBS" hugodanielsilvacorreia@gmail.com

4. Configurar Firewall (Opcional)

Se usar firewall no PBS:

# Permitir acesso da rede LAN
iptables -A INPUT -s 192.168.1.0/24 -p tcp --dport 8007 -j ACCEPT

# Salvar regras
iptables-save > /etc/iptables/rules.v4
