# 🚀 ПОЛНЫЙ REDEPLOY: 2 сервера + документация!
|
||||
|
||||
Ты абсолютно прав — мой косяк, не проверил профиль. Идём! 💪

## ПЛАН ДЕЙСТВИЙ 🎯
|

text
|
||||
|
||||
`1. Создать server-deployment.md (документация) 2. Сгенерировать новые SOPS секреты 3. Redeploy на первый сервер через nixos-anywhere 4. Тест 5. Redeploy на второй сервер 6. Финальная проверка`
|
||||
|
||||

|
||||
|
||||
## Шаг 1: Создай документацию 📖
|
||||
|
||||
bash
|
||||
|
||||
``cd ~/nix-server # Создай гайд для будущих deployments cat > server-deployment.md << 'EOF' --- tags: [nixos, deployment, guide, production] --- # NixOS Server Deployment Guide ## Prerequisites - Fresh Linux VPS (Debian 12, Ubuntu 22.04, etc.) - SSH access as root - nixos-anywhere installed locally: `nix-shell -p nixos-anywhere` ## Step 1: Generate VPN Secrets``
|
||||
|
||||
# On local machine
|
||||
|
||||
cd ~/nix-server
|
||||
|
||||
# Generate new age key for this server
|
||||
|
||||
age-keygen -o ~/.config/sops/age/server2-keys.txt
|
||||
|
||||
# Create secrets file
|
||||
|
||||
cat > secrets.yaml << 'SECRETS'
|
||||
vpn:
|
||||
uuid: "$(uuidgen)"
|
||||
privateKey: "$(openssl rand -base64 32)"
|
||||
shortId: "$(openssl rand -hex 8)"
|
||||
SECRETS
|
||||
|
||||
# Encrypt with sops
|
||||
|
||||
sops secrets.yaml
|
||||
|
||||
text
|
||||
|
||||
`## Step 2: Update flake.nix with new keys`
|
||||
|
||||
# In flake.nix
|
||||
|
||||
sops.age.keyFile = "/root/.config/sops/age/keys.txt";
|

|

text
|
||||
|
||||
`## Step 3: Deploy with nixos-anywhere`
|
||||
|
||||
# Local machine
|
||||
|
||||
nixos-anywhere --flake .#server root@NEW-SERVER-IP
|
||||
|
||||
# Wait for reboot...
|
||||
|
||||
sleep 60
|
||||
|
||||
# Verify
|
||||
|
||||
ssh nxoska@NEW-SERVER-IP
|
||||
sudo systemctl status sing-box
|
||||
timedatectl status # MUST be: synchronized: yes
|
||||
|
||||
text
|
||||
|
||||
`## Step 4: Verify Everything`
|
||||
|
||||
ssh nxoska@NEW-SERVER-IP
|
||||
|
||||
# 1. Time sync
|
||||
|
||||
timedatectl status
|
||||
|
||||
# Output: System clock synchronized: yes ✅
|
||||
|
||||
# 2. sing-box running
|
||||
|
||||
sudo systemctl status sing-box
|
||||
|
||||
# Output: active (running) ✅
|
||||
|
||||
# 3. Port listening
|
||||
|
||||
sudo ss -tulpn | grep 443
|
||||
|
||||
# Output: LISTEN [::]:443 ✅
|
||||
|
||||
# 4. Secrets loaded
|
||||
|
||||
sudo -u sing-box cat /run/secrets/vpn/uuid
|
||||
|
||||
# Output: your-uuid ✅
|
||||
|
||||
# 5. VPN functional
|
||||
|
||||
# Test from client (another machine)
|
||||
|
||||
text
|
||||
|
||||
`## Troubleshooting ### Time sync not working`
|
||||
|
||||
sudo systemctl restart systemd-timesyncd
|
||||
sleep 5
|
||||
timedatectl timesync-status
|
||||
|
||||

|
||||
|
||||
`### sing-box permission denied`
|
||||
|
||||
# Check secrets owner
|
||||
|
||||
ls -la /run/secrets/vpn/
|
||||
|
||||
# Should be: -r-------- sing-box sing-box
|
||||
|
||||
# If not, rebuild:
|
||||
|
||||
sudo nixos-rebuild switch --flake .#server
|
||||
|
||||
text
|
||||
|
||||
`### Connection refused on port 443`
|
||||
|

sudo journalctl -u sing-box -n 50
|

sudo ss -tulpn | grep -E "(443|sing-box)"
|

`## Rollback Plan If something breaks:`

## Шаг 2: Сгенерируй новые секреты 🔐
|
||||
|
||||
bash
|
||||
|
||||
`cd ~/nix-server # 1. Новый UUID для VPN NEW_UUID=$(uuidgen) echo "New UUID: $NEW_UUID" # 2. Новый private key NEW_PRIVATE_KEY=$(openssl rand -base64 32) echo "New Private Key: $NEW_PRIVATE_KEY" # 3.

Обнови secrets.yaml cat > secrets.yaml << EOF vpn: uuid: "$NEW_UUID" privateKey: "$NEW_PRIVATE_KEY" shortId: "$NEW_SHORT_ID" EOF # 5. Зашифруй SOPS sops secrets.yaml # 6. Проверь что зашифровано cat secrets.yaml | head -5 # Должно быть: ENC[AES256_GCM,...] ✅ # 7. Коммит (encrypted файл безопасен!) git add secrets.yaml git commit -m "chore: regenerate VPN secrets for clean deployment"`

## Шаг 3: Первый сервер — REDEPLOY 🚀
|
||||
|
||||
bash
|
||||
|
||||
`# ВАЖНО: Создай backup ssh nxoska@64.188.70.209 'sudo tar czf /tmp/backup-old.tar.gz /etc/nixos/ /var/lib/sing-box/' scp nxoska@64.188.70.209:/tmp/backup-old.tar.gz ~/backups/server1-backup-2025-10-30.tar.gz # Отключи VPN клиентов!

|

|
||||
|
||||
## Шаг 4: Второй сервер — REDEPLOY 🚀
|
||||
|
||||
bash
|
||||
|
||||
`# Если у тебя есть второй сервер (например, для HA) # Процесс идентичный! echo "🚀 Starting redeploy on server 2..." nixos-anywhere --flake .#server root@SECOND-SERVER-IP sleep 120 echo "🔍 Verifying server 2..." ssh nxoska@SECOND-SERVER-IP << 'VERIFY' timedatectl status sudo systemctl status sing-box --no-pager | head -10 sudo journalctl -u sing-box -n 20 --no-pager VERIFY`

## Запуск 🎬
|
||||
|
||||
bash
|
||||
|
||||
`# Создай скрипт cat > ~/deploy-vpn-servers.sh << 'SCRIPT_EOF' # (содержимое скрипта выше) SCRIPT_EOF chmod +x ~/deploy-vpn-servers.sh # Запусти cd ~/nix-server ~/deploy-vpn-servers.sh # Или по одному (если хочешь контролировать) nixos-anywhere --flake .#server root@64.188.70.209 sleep 120 ssh nxoska@64.188.70.209 'timedatectl status && sudo systemctl status sing-box'`
|
||||

|
||||
|
||||
## Финальная проверка ✅
|
||||
|
||||
bash
|
||||
|
||||
`# На каждом сервере: ssh nxoska@64.188.70.209 # ALL 4 должны быть ✅ echo "=== CHECK 1: Time Sync ===" && timedatectl status | grep "synchronized" echo "=== CHECK 2: sing-box ===" && sudo systemctl status sing-box --no-pager | grep "active" echo "=== CHECK 3: Port ===" && sudo ss -tulpn | grep 443 echo "=== CHECK 4: Secrets ===" && sudo -u sing-box cat /run/secrets/vpn/uuid # Если все 4 выводят что надо — ВСЁ ОТЛИЧНО! 🎉`
|
||||

|
||||
|
||||
## КОММИТЫ
|
||||
|
||||
bash
|
||||
|
||||
`git add . git commit -m "🚀 Complete redeploy with nixos-anywhere - Use nixos-anywhere instead of deprecated nixos-infect - Regenerate all VPN secrets - Add server-deployment.md documentation - Clean NixOS installation on both servers - Proper systemd-timesyncd configuration - All systems verified and working ✅" git push`
