# Deploy — SuperAdmin on shared montime host

Host: `185.50.38.53` (SSH port `3031`)  
Domain: `https://adm.montzar.ir`  
DB: Postgres `superadmin` (owner `montime`) — already created  
API port: `3010` (3000=montime, 3001=forisanad)

## Layout on server

```text
/var/www/superadmin/
  api/                 # clone of controlPanel/api.git
    deploy/            # nginx + pm2 + this guide (in api repo)
  web/                 # clone of controlPanel/web.git (Vue dist)
```

## 1) Clone / pull

```bash
sudo mkdir -p /var/www/superadmin
sudo chown montime:montime /var/www/superadmin

cd /var/www/superadmin
git clone https://get.feep.ir/controlPanel/api.git api
git clone https://get.feep.ir/controlPanel/web.git web
```

Later updates: `git pull` in each folder.

## 2) API `.env`

```bash
cd /var/www/superadmin/api
cp .env.example .env
nano .env
```

Required:

```env
NODE_ENV=production
PORT=3010
DATABASE_URL="postgresql://montime:YOUR_PASSWORD@127.0.0.1:5432/superadmin?schema=public"
JWT_SECRET="long-random-production-secret"
JWT_EXPIRES_IN="7d"
CORS_ORIGIN="https://adm.montzar.ir"
PUBLIC_API_URL="https://adm.montzar.ir"
SEED_ADMIN_MOBILE="09128081392"
SEED_ADMIN_PASSWORD="change-me"
# CENTRAL_SMS_* as needed
```

Password = same Postgres password that works for `psql -h 127.0.0.1 -U montime -d superadmin`.

## 3) Install, migrate, build, seed

```bash
cd /var/www/superadmin/api
npm ci
npx prisma generate
npx prisma migrate deploy
npm run build
npm run prisma:seed
# optional first import:
# npm run prisma:import-users
```

## 4) PM2

```bash
pm2 start /var/www/superadmin/api/deploy/ecosystem.config.cjs
pm2 save
pm2 status
curl -s http://127.0.0.1:3010/api/health || true
```

## 5) Web build

Same-origin: leave `VITE_API_BASE` unset (defaults to `/api`).

```bash
cd /var/www/superadmin/web
npm ci
npm run build
# dist → /var/www/superadmin/web/dist
```

## 6) Nginx

```bash
sudo cp /var/www/superadmin/api/deploy/nginx-adm.montzar.ir.conf /etc/nginx/sites-available/adm.montzar.ir
sudo ln -sf /etc/nginx/sites-available/adm.montzar.ir /etc/nginx/sites-enabled/
sudo nginx -t && sudo systemctl reload nginx
```

SSL: if Certbot already issued for `adm.montzar.ir`, paths in the conf should match. Otherwise:

```bash
sudo certbot --nginx -d adm.montzar.ir
```

## 7) Smoke

1. Open `https://adm.montzar.ir` → login  
2. `https://adm.montzar.ir/get_user?domain=montpar.ir` (or any known domain)  
3. `https://adm.montzar.ir/get_settings?domain=k.montzar.ir` (nginx must proxy `/get_settings` like `/get_user`)  
4. Confirm uploads/logo URLs use `PUBLIC_API_URL`

## 8) Migrations with logical replication (failover replicas)

`superadmin_pub` streams rows to the failover hosts (`adm.montech.ir`, `adm.montest.ir`).
Logical replication does **not** carry DDL: a migration that adds a column on the
publisher makes every subscriber fail with `missing replicated columns` and the
subscription stalls until that column exists there too. Because `_prisma_migrations`
is replicated, `prisma migrate deploy` on a subscriber wrongly reports
"No pending migrations".

So never run `migrate deploy` alone. On the publisher host:

```bash
cp deploy/replicas.env.example deploy/replicas.env   # once; add real DSNs
bash deploy/sync-replica-schema.sh --init            # once, when schemas already match
```

For every release on **publisher** (`/var/www/superadmin/api`):

```bash
git pull
npm run replicas:sync      # 1) DDL on replicas  2) migrate deploy  3) repair data drift if any
npx prisma generate
npm run build
pm2 restart superadmin-api
```

Check only:

```bash
npm run replicas:check     # schema + subscription + row counts (settings, tenants, …)
```

Force data realign from publisher (rare — e.g. after fixing subscriber permissions):

```bash
npm run replicas:repair-data
```

`replicas:sync` runs `sync-replica-data.sh --repair-if-needed` automatically when
`settings` / `setting_templates` / `tenants` counts differ from publisher.

On the **publisher API** (`superadmin-api`), a replica watch also runs: ~8s after
boot, then every 60s, and immediately after tenant/settings writes. Drift is
healed without an operator command. Logical replication still streams live
INSERT/UPDATE/DELETE; the watch only fills **missed history** (WAL is not
rewound).

Each replica API user (`montime` by default) needs `SELECT` on all tables — the
repair script re-applies grants. `REPLICA_DSNS` must connect as a role that can
`TRUNCATE` + `ALTER SUBSCRIPTION` on the subscriber. The watch is idle unless
`deploy/replicas.env` exists on that host.

Keep migrations schema-only. After each migrate, subscribers get
`ALTER SUBSCRIPTION … REFRESH PUBLICATION WITH (copy_data = true)` so **new
tables** join replication (Postgres does not add them by itself).

## 9) Data changes **without** deploy (import settings, edit tenant, …)

**Normal path:** publisher writes → `superadmin_pub` WAL → slaves apply in
**seconds**. No `replicas:sync` for that.

**Why LSN-healthy slaves can still have empty `settings`:** logical replication
is a **stream**, not a mirror. `received_lsn = latest_end_lsn` means “caught up
with current WAL”, not “every historical row exists”. Rows inserted while apply
was broken, or while the table was **not yet in the subscription**, are never
replayed. Postgres will not go back.

That gap is healed **automatically on the publisher API** (watch every 60s +
right after import/edit). You do **not** run `replicas:repair-data` by hand
once this build is running on `/var/www/superadmin/api`.

| Action | What actually happens |
|--------|------------------------|
| INSERT/UPDATE/DELETE while subscription is ready | Live WAL — slaves update immediately |
| New table after `FOR ALL TABLES` publication | Not replicated until `REFRESH PUBLICATION` (deploy `replicas:sync` does this) |
| Missed history (this tenant’s empty settings) | Watch compares counts and recopies from publisher, then live WAL resumes |

`npm run replicas:check` / `replicas:repair-data` remain for operators; they are
not required for day-to-day imports after the watch is up.

## Local development note

Prisma provider is **PostgreSQL** only. Local options:

- Docker: `docker run -d -p 5432:5432 -e POSTGRES_PASSWORD=postgres -e POSTGRES_DB=superadmin postgres:16`
- Or point `DATABASE_URL` at the server DB only for short tests (prefer local DB)

SQLite history is kept under `prisma/migrations_sqlite_archive/` (reference only; not applied by `migrate deploy`).
