# ShopDB - Windows + IIS install runbook

A step-by-step, **tested** install for a new site on Windows Server / Windows 11
with IIS in front of the Flask app (HttpPlatformHandler -> waitress), backed by
MySQL. This runbook was validated end to end on a win11 + IIS + MySQL 5.6 box.

`APP_ROOT` below = the deploy folder, e.g. `C:\shopdb-flask` (where `wsgi.py`
lives). Run PowerShell as Administrator.

---

## 0. Prerequisites

| Need | Notes |
| --- | --- |
| **Python 3.12** (64-bit) | `python --version` |
| **IIS** with **HttpPlatformHandler** | https://www.iis.net/downloads/microsoft/httpplatformhandler (direct MSI: `download.microsoft.com/download/8/1/3/813AC4E6-9203-4F7A-8DD5-F3D54D10C5CD/httpPlatformHandler_amd64.msi`) |
| **MySQL 5.7+/8.0** (or 5.6 with the flags in step 1) | reachable from the app host |
| URL Rewrite (optional) | only for the real-client-IP rule; skip it and the app still runs |

The app itself pulls in `waitress` and `tzdata` from `requirements.txt` (step 4).

---

## 1. MySQL: flags (5.6 only) + database + user

On **MySQL 5.6 only**, add to `my.ini`/`my.cnf` under `[mysqld]` and restart MySQL
(5.7+/8.0 need none of this):

```
innodb_file_per_table = 1
innodb_file_format    = Barracuda
innodb_large_prefix   = 1
```

Without them, `flask db upgrade` fails with **error 1071** ("key too long") - the
migrations use `ROW_FORMAT=DYNAMIC`, which needs the 3072-byte prefix these unlock.

Then create the database (utf8mb4) and an app user:

```sql
CREATE DATABASE shopdb_flask CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;
CREATE USER 'shopdb'@'%' IDENTIFIED BY 'CHANGE_ME';
GRANT ALL PRIVILEGES ON shopdb_flask.* TO 'shopdb'@'%';
FLUSH PRIVILEGES;
```

---

## 2. Deploy the app files

Copy the release (the repo minus `venv/`, `.git/`, `node_modules/`,
`frontend/src/`) to `APP_ROOT`. It must contain `wsgi.py`, `shopdb/`, `plugins/`,
`migrations/`, `requirements.txt`, and the pre-built `frontend/dist/`.

---

## 3. Virtual env + dependencies

```powershell
cd APP_ROOT
python -m venv venv
venv\Scripts\python -m pip install -r requirements.txt
```

This installs Flask, SQLAlchemy, PyMySQL, **waitress** (the WSGI server IIS
launches) and **tzdata** (Windows has no IANA tz database; without it the
notifications plugin fails with "No time zone found with key America/New_York").

---

## 4. Secrets + connection (.env)

Create `APP_ROOT\.env` (read by `wsgi.py` via `load_dotenv()`). Lock its ACLs to
the app-pool identity + admins.

```
FLASK_ENV=production
SECRET_KEY=<64+ random chars>
JWT_SECRET_KEY=<another 64+ random chars>
DATABASE_URL=mysql+pymysql://shopdb:CHANGE_ME@<mysql-host>:3306/shopdb_flask?charset=utf8mb4
CORS_ORIGINS=http://<the site's own hostname-or-ip:port>
```

Generate a key: `venv\Scripts\python -c "import secrets;print(secrets.token_urlsafe(64))"`.
Production **refuses to boot** if any of `SECRET_KEY`, `JWT_SECRET_KEY`,
`DATABASE_URL`, `CORS_ORIGINS` is missing or a dev default.

---

## 5. Preflight (catch problems before installing)

```powershell
$env:FLASK_APP="shopdb"
venv\Scripts\flask db-utils preflight
```

Checks Python, required env, DB connectivity, and the MySQL 5.6 index flags, and
prints exactly what to fix. Fix any **FAIL** before continuing.

---

## 6. Schema + data + plugins + admin

```powershell
$env:FLASK_APP="shopdb"

venv\Scripts\flask db upgrade                # creates every table (to head)
venv\Scripts\flask seed reference-data       # statuses, machine/location/rel types
venv\Scripts\flask seed permissions
venv\Scripts\flask seed settings

# enable the plugins this site tracks (registry is empty on a fresh box).
# usb + employees install DISABLED by default - enable them later in the wizard
# if the site wants those (they create extra tables).
foreach ($p in "computers","equipment","network","notifications","printers","knowledgebase","slides","warranty") {
  venv\Scripts\flask plugin install $p
}

# first admin (password generated + printed once - store it):
venv\Scripts\flask seed admin --username admin --email admin@yourfacility.example.com
```

> Prefer no CLI? Skip `seed admin` (and even the seed steps): start the site, and
> the login page offers to **create the first admin** on a fresh instance, then
> the setup wizard can seed reference data. Either path works.

---

## 7. IIS site

1. Copy `deploy\windows\web.config` to `APP_ROOT\web.config`. If `APP_ROOT` is not
   `C:\shopdb-flask`, fix the paths inside it. Create `APP_ROOT\logs`.
2. Create an app pool with **No Managed Code**:
   ```powershell
   Import-Module WebAdministration
   New-WebAppPool -Name shopdbflask
   Set-ItemProperty IIS:\AppPools\shopdbflask -Name managedRuntimeVersion -Value ""
   ```
3. Grant the app-pool identity access:
   ```powershell
   icacls APP_ROOT /grant "IIS AppPool\shopdbflask:(OI)(CI)RX" /T
   icacls APP_ROOT\logs /grant "IIS AppPool\shopdbflask:(OI)(CI)M" /T
   ```
4. **Unlock the handler sections** (locked server-wide by default; without this
   IIS returns **HTTP 500.19**):
   ```powershell
   %windir%\system32\inetsrv\appcmd unlock config /section:system.webServer/handlers
   %windir%\system32\inetsrv\appcmd unlock config /section:system.webServer/httpPlatform
   ```
5. Create the site (own port; the classic ASP site can keep 8080):
   ```powershell
   New-Website -Name shopdb-flask -Port 8090 -PhysicalPath APP_ROOT -ApplicationPool shopdbflask
   New-NetFirewallRule -DisplayName "shopdb-flask 8090" -Direction Inbound -Protocol TCP -LocalPort 8090 -Action Allow
   Start-Website shopdb-flask
   ```

IIS launches `waitress-serve --port=%HTTP_PLATFORM_PORT% wsgi:app` per the
web.config and reverse-proxies the site port to it. First request takes ~15s
(the app boots + connects to MySQL).

> The `X-Forwarded-For` URL Rewrite rule in web.config is **commented out by
> default**. It needs the URL Rewrite module; with it active but the module
> absent, IIS returns 500.19. Install URL Rewrite, then uncomment the
> `<rewrite>` block, to record real client IPs in audit logs.

---

## 8. Smoke test + first run

```powershell
(Invoke-WebRequest http://localhost:8090/ -UseBasicParsing).StatusCode      # 200 (SPA)
Invoke-WebRequest http://localhost:8090/api/auth/login -Method POST `
  -Body '{"username":"admin","password":"<the printed password>"}' `
  -ContentType application/json -UseBasicParsing                            # 200 + token
```

Browse to `http://<host>:8090`, sign in as the admin, and the **setup wizard**
walks through site name, features (per-plugin: create tables here vs connect a DB),
floor-map upload, and starter data. Multiple Flask apps can share one IIS box -
each gets its own site, app pool, port, and venv.

## Troubleshooting

| Symptom | Cause / fix |
| --- | --- |
| `flask db upgrade` -> error **1071** | MySQL 5.6 without the step-1 flags (or server not restarted). |
| IIS **500.19** | handler sections not unlocked (step 7.4), or the `<rewrite>` block active without URL Rewrite. |
| **500** with an empty HttpPlatform log | app-pool identity can't read `APP_ROOT` / run the venv (step 7.3), or `.env` missing/invalid. |
| "No time zone found with key America/New_York" | `tzdata` not installed (`pip install tzdata`). |
| Nav missing Equipment/PCs/... | plugins not installed (step 6 `flask plugin install`), or site not recycled. |
| ConfigError on boot | a required `.env` var missing or left at a dev default. |
