 # Установка без Docker (Ubuntu)
 
-Production-развёртывание на **Ubuntu 22.04 / 24.04**: Node.js 20, PostgreSQL 17, systemd, опционально Caddy.
+Production: Node.js 20, PostgreSQL 17, systemd, опционально Caddy.
+
+**Полное руководство по ошибкам и обновлениям:** [Server-Operations](Server-Operations).
+
+Задайте каталог клона:
+
+```bash
+export SHOP_ROOT=/opt/shop
+```
+

 ## 1. Требования
 
-- Сервер Ubuntu 22.04 или 24.04 (root или sudo)
+- Ubuntu 22.04 или 24.04
-- Минимум 1 GB RAM, 10 GB диск
+- Порты 22, 80, 443 (для Caddy)
-- Открыты порты **22**, **80**, **443** (если используете Caddy)
+- Порт 3000 только localhost
-- Порт **3000** наружу не открывать — только localhost
 
-## 2. Установка системных пакетов
+## 2. Системные пакеты
 
-```bash
+### Node.js 20
-apt update
-apt install -y git curl ca-certificates
-```
-
-### Node.js 20 LTS
 
 ```bash
 curl -fsSL https://deb.nodesource.com/setup_20.x | bash -
-apt install -y nodejs
+apt install -y nodejs git curl
-node -v   # v20.x
 ```
 
 ### PostgreSQL 17
 
+Не используйте `apt install postgresql-17` без PGDG:
+
 ```bash
-apt install -y postgresql-17 postgresql-client-17
+sudo bash "$SHOP_ROOT/scripts/install-postgresql-ubuntu.sh"
-systemctl enable postgresql
-systemctl start postgresql
-pg_isready -h 127.0.0.1 -p 5432
 ```
 
-Если пакет `postgresql-17` не найден — [репозиторий PGDG](https://www.postgresql.org/download/linux/ubuntu/):
+## 3. Клонирование
 
 ```bash
-apt install -y curl ca-certificates

 ```
 
-## 3. Клонирование проекта
+Или: `sudo SHOP_GIT_URL="$GIT_REPO_URL" bash scripts/quick-deploy-ubuntu.sh`
+
+## 4. База данных
 
 ```bash
-cd /opt
+cd "$SHOP_ROOT"
-git clone https://git.evilfox.cc/test/shop10.git shop
-cd shop
-git checkout v0.10.0
-```
-
-## 4. База данных PostgreSQL
-
-```bash
-cd /opt/shop
 bash scripts/setup-postgres-ubuntu.sh
 ```
 
-Скрипт:
+## 5. `.env`
-- запускает PostgreSQL;
-- создаёт пользователя и БД `shop` (по умолчанию пароль `shop` — **смените в production**);
-- выводит строку `DATABASE_URL`.
-
-Проверка:
-
-```bash
-psql "postgresql://shop:shop@127.0.0.1:5432/shop" -c "SELECT 1"
-```
-
-## 5. Файл окружения `.env`
 
 ```bash
 cp .env.example .env
 nano .env
 ```
 
-Обязательные параметры:
+`SESSION_SECRET`, `DATABASE_URL`, `SITE_URL` (ваш публичный URL без привязки к конкретному домену в коде).
 
-```env
+## 6. Зависимости
-PORT=3000
-HOST=127.0.0.1
-NODE_ENV=production
-TRUST_PROXY=1
-SESSION_SECRET=сгенерируйте_длинную_строку
-DATABASE_URL=postgresql://shop:ВАШ_ПАРОЛЬ@127.0.0.1:5432/shop
-```
-
-Секрет сессии:
 
 ```bash
-openssl rand -hex 32
-```
-
-`HOST=127.0.0.1` — приложение доступно только локально; снаружи — через Caddy.
-
-## 6. Установка зависимостей Node.js
-
-```bash
-cd /opt/shop
 npm install --omit=dev
 ```
 
-При первом запуске приложение создаст таблицы и демо-товары (если каталог пуст).
+## 7. systemd
-
-## 7. Служба systemd
 
 ```bash
-cp /opt/shop/deploy/shop.service /etc/systemd/system/shop.service
+sudo bash scripts/install-shop-service.sh
-systemctl daemon-reload
-systemctl enable shop
-systemctl start shop
-systemctl status shop
 ```
 
-Unit ждёт PostgreSQL (`ExecStartPre` + `pg_isready`) и запускает Node от пользователя `www-data`.
+`WorkingDirectory` в unit = `$SHOP_ROOT`. Не делайте `chown -R www-data` на весь репозиторий.
 
-**Важно:** не выполняйте `chown -R www-data /opt/shop` — это ломает `git pull`. Права на запись нужны только для каталога `data/` (если используется); с PostgreSQL каталог `data/` не обязателен.
+## 8. Caddy
 
-Логи:
+После `curl http://127.0.0.1:3000/health` → OK:
 
 ```bash
-journalctl -u shop -f
+cp "$SHOP_ROOT/caddy/Caddyfile.example" /etc/caddy/Caddyfile
-```
+# укажите ваш домен в Caddyfile
-
-## 8. Проверка backend
-
-```bash
-curl -s http://127.0.0.1:3000/health
-ss -tlnp | grep 3000
-```
-
-В логах должно быть: `Магазин: http://127.0.0.1:3000 (PostgreSQL)`
-
-## 9. Caddy — HTTPS и reverse proxy
-
-Установка Caddy:
-
-```bash
-apt install -y debian-keyring debian-archive-keyring apt-transport-https
-curl -1sLf 'https://dl.cloudsmith.io/public/caddy/stable/gpg.key' \
-  | gpg --dearmor -o /usr/share/keyrings/caddy-stable-archive-keyring.gpg
-curl -1sLf 'https://dl.cloudsmith.io/public/caddy/stable/debian.deb.txt' \
-  | tee /etc/apt/sources.list.d/caddy-stable.list
-apt update && apt install -y caddy
-```
-
-Конфигурация:
-
-```bash
-cp /opt/shop/caddy/Caddyfile.example /etc/caddy/Caddyfile
-nano /etc/caddy/Caddyfile
-```
-
-Пример (замените домен и email):
-
-```caddyfile
-{
-	email admin@example.com
-}
-
-shop.example.com {
-	encode gzip zstd
-	reverse_proxy 127.0.0.1:3000
-}
-```
-
-```bash
-caddy validate --config /etc/caddy/Caddyfile
-systemctl enable caddy
 systemctl reload caddy
 ```
 
-Файрвол:
+## 9. Обновление
 
 ```bash
-ufw allow 22/tcp
+bash "$SHOP_ROOT/scripts/server-update.sh"
-ufw allow 80/tcp
-ufw allow 443/tcp
-ufw enable
 ```
 
-Зависимость Caddy от shop (опционально):
+## 10. Архитектура
-
-```bash
-mkdir -p /etc/systemd/system/caddy.service.d
-cp /opt/shop/deploy/caddy-after-shop.conf /etc/systemd/system/caddy.service.d/shop.conf
-systemctl daemon-reload
-```
-
-## 10. Обновление
-
-```bash
-cd /opt/shop
-git config --global --add safe.directory /opt/shop
-bash scripts/server-update.sh
-```
-
-Или вручную:
-
-```bash
-git pull
-npm install --omit=dev
-systemctl restart shop
-curl -s http://127.0.0.1:3000/health
-systemctl reload caddy
-```
-
-## 11. Переход с SQLite (старая версия)
-
-1. Установите PostgreSQL (шаги 2–4)
-2. Добавьте `DATABASE_URL` в `.env`
-3. `git pull` → `npm install` → `systemctl restart shop`
-4. Демо-товары появятся автоматически; пользователей нужно зарегистрировать заново
-
-Быстрое исправление подключения к БД:
-
-```bash
-bash /opt/shop/scripts/fix-db-connection.sh

+Инструкция **без привязки к конкретному домену или хостингу**. Подставьте свои значения:
+
+| Переменная | Что это | Пример |
+|------------|---------|--------|
+| `SHOP_ROOT` | Каталог клона, где лежат `package.json` и `scripts/` | `/opt/shop` |
+| `GIT_REPO_URL` | URL вашего git-репозитория | `https://forge.example.com/user/shop.git` |
+| `SITE_URL` | Публичный URL магазина (для писем и passkey) | `https://shop.example.com` |
+
+Проверка каталога:
+
+```bash
+export SHOP_ROOT=/opt/shop
+test -f "$SHOP_ROOT/package.json" && echo OK || echo "Неверный SHOP_ROOT"
+```
+
+---
+
+## Интерактивный установщик (рекомендуется)
+
+```bash
+cd "$SHOP_ROOT"
+bash scripts/install.sh
+```
+
+Скрипт спросит:
+
+1. **Docker** или **Ubuntu без Docker**
+2. Email, имя и пароль **администратора**
+3. Пользователь, пароль и имя базы **PostgreSQL**
+4. **URL сайта**, секрет сессий (можно сгенерировать)
+5. Опционально **SMTP**
+6. Для Docker — порт и включить ли **Caddy**
+
+Создаётся файл `.env`, затем запускается `docker compose` или `systemd`.
+
+---
+
+## Первая установка (Ubuntu, без Docker)
+
+```bash
+export SHOP_ROOT=/opt/shop
+export GIT_REPO_URL='https://ВАШ-FORGE/путь/к/shop.git'
+
+apt update && apt install -y git curl
+git clone "$GIT_REPO_URL" "$SHOP_ROOT"
+cd "$SHOP_ROOT"
+
+sudo SHOP_INSTALL_DIR="$SHOP_ROOT" SHOP_GIT_URL="$GIT_REPO_URL" \
+  bash scripts/quick-deploy-ubuntu.sh
+```
+
+Скрипт: Node.js (если нет), PostgreSQL (PGDG), `.env`, `npm install`, служба **shop** (systemd).
+
+---
+
+## Обновление кода (сайт уже работает)
+
+**Рекомендуется** — две команды (можно из любого каталога, не нужен `cd`):
+
+```bash
+export SHOP_ROOT=/opt/shop/shop10
+bash "$SHOP_ROOT/scripts/server-update.sh"
+```
+
+Подставьте свой путь к клону (где лежит `package.json`). Часто это `/opt/shop` или `/opt/shop/shop10`.
+
+Почему так надёжнее, чем `cd /opt/shop && git pull`:
+
+- явно задан каталог репозитория (`SHOP_ROOT`);
+- внутри выполняются `git-sync` (ветка `main`), `npm install`, перезапуск `shop`, проверка `/health`;
+- не перепутаете родительскую папку без `package.json` и скриптов.
+
+Проверка после обновления:
+
+```bash
+systemctl status shop
+curl -s http://127.0.0.1:3000/health
+```
+
+Если git в detached HEAD отдельно:
+
+```bash
+cd "$SHOP_ROOT"
+bash scripts/git-sync.sh
+bash scripts/server-update.sh
+```
+
+---
+
+## Скрипты в `scripts/`
+
+| Скрипт | Назначение |
+|--------|------------|
+| `install.sh` | **Интерактивная установка** (Docker или Ubuntu) |
+| `quick-deploy-ubuntu.sh` | Первая установка / полный цикл (без вопросов) |
+| `server-update.sh` | `git pull`, `npm install`, перезапуск shop |
+| `git-sync.sh` | Исправить detached HEAD, синхронизация с `main` |
+| `install-postgresql-ubuntu.sh` | PostgreSQL 17 через PGDG |
+| `setup-postgres-ubuntu.sh` | Пользователь и БД `shop` |
+| `install-shop-service.sh` | Установка systemd unit |
+| `free-port-3000.sh` | Освободить порт (старый `npm start`) |
+| `fix-db-connection.sh` | ECONNREFUSED :5432 |
+| `diagnose-502.sh` | HTTP 502, Caddy |
+| `diagnose-shop-service.sh` | Падение shop.service |
+
+Все скрипты сами ищут `SHOP_ROOT` (каталог, откуда вызван `scripts/`, или переменная окружения).
+
+---
+
+## Частые ошибки
+
+### `Unable to locate package postgresql-17`
+
+В стандартном Ubuntu нет пакета 17. Не копируйте `apt install postgresql-17` из старых заметок.
+
+```bash
+sudo bash "$SHOP_ROOT/scripts/install-postgresql-ubuntu.sh"
+bash "$SHOP_ROOT/scripts/setup-postgres-ubuntu.sh"
+```
+
+### `URL_РЕПОЗИТОРИЯ: No such file` или placeholder в команде
+
+В документации иногда указан **шаблон**, а не команда. Клонируйте так:
+
+```bash
+git clone 'https://ВАШ-FORGE/shop.git' "$SHOP_ROOT"
+```
+
+### `package.json` ENOENT в `/opt/shop`
+
+Вы в **родительской** папке, а клон в подкаталоге (или наоборот).
+
+```bash
+find /opt -name package.json 2>/dev/null
+export SHOP_ROOT=/путь/где/найден
+cd "$SHOP_ROOT"
+```
+
+### `You are not currently on a branch`
+
+После `git checkout v0.x.x` репозиторий в detached HEAD.
+
+```bash
+cd "$SHOP_ROOT"
+bash scripts/git-sync.sh
+```
+
+### `scripts/...: No such file or directory`
+
+Запуск не из клона. Используйте полный путь:
+
+```bash
+bash "$SHOP_ROOT/scripts/server-update.sh"
+```
+
+### `Служба shop не установлена` / `Unit shop.service could not be found`
+
+```bash
+cd "$SHOP_ROOT"
+sudo bash scripts/install-shop-service.sh
+```
+
+В `/etc/systemd/system/shop.service` поля `WorkingDirectory` и `EnvironmentFile` должны указывать на **`$SHOP_ROOT`**.
+
+### `shop.service: status=1/FAILURE`, `activating (auto-restart)`
+
+1. **Порт 3000 занят** (старый ручной Node) — health отвечает, systemd падает:
+
+```bash
+sudo bash "$SHOP_ROOT/scripts/free-port-3000.sh"
+sudo systemctl restart shop
+systemctl status shop
+```
+
+2. **PostgreSQL** — смотрите лог:
+
+```bash
+journalctl -u shop -n 40 --no-pager
+bash "$SHOP_ROOT/scripts/diagnose-shop-service.sh"
+```
+
+3. **`.env` не в `SHOP_ROOT`** — скопируйте с прежнего места:
+
+```bash
+cp /старый/путь/.env "$SHOP_ROOT/.env"
+sudo bash "$SHOP_ROOT/scripts/install-shop-service.sh"
+```
+
+### Изменения в git не видны на сайте
+
+Обновление делали не в том каталоге или служба смотрит на другой путь:
+
+```bash
+cd "$SHOP_ROOT" && git log -1 --oneline
+grep WorkingDirectory /etc/systemd/system/shop.service
+bash scripts/server-update.sh
+```
+
+---
+
+## Проверка
+
+```bash
+systemctl status shop
+curl -s http://127.0.0.1:3000/health
+```
+
+Ожидается: `{"ok":true,"service":"shop","database":"postgresql"}` и **`Active: active (running)`**.
+
+---
+
+## Caddy / HTTPS
+
+Пока `curl http://127.0.0.1:3000/health` не OK, reverse proxy будет отдавать **502**. Сначала backend, потом Caddy.
