3 IIS sites

Site	Binding	Physical path	Apool	Purpose
SolutionErp-Api	*:443:api.huypham.vn HTTPS	C:\inetpub\apps\SolutionErp\Api\	out-of-process Kestrel	ASP.NET Core 10 API (port 5443 internal)
SolutionErp-Admin	*:443:admin.huypham.vn HTTPS + *:80 redirect	C:\inetpub\apps\SolutionErp\Admin\	static (no app pool .NET)	React build fe-admin
SolutionErp-User	*:443:user.huypham.vn HTTPS + *:80 redirect	C:\inetpub\apps\SolutionErp\User\	static	React build fe-user

SPA web.config: 2 FE có URL Rewrite rule:

1. HTTP → HTTPS redirect (bắt buộc, CORS whitelist chỉ https)
2. /api/* → http://localhost:5443/api/* (ARR reverse proxy)
3. /hubs/* → http://localhost:5443/hubs/* (SignalR)
4. React Router fallback: /* → /index.html

Quick commands

Restart 1 site

# PowerShell as Admin
Import-Module WebAdministration
Stop-WebSite -Name "SolutionErp-Api"
Start-WebSite -Name "SolutionErp-Api"

# Hoặc recycle app pool (API out-of-process):
Restart-WebAppPool -Name "SolutionErp-Api"

# Check site status:
Get-Website -Name "SolutionErp-*" | Format-Table Name, State, Bindings

Xem log API

# Serilog file rolling daily
Get-Content "C:\inetpub\apps\SolutionErp\Api\Logs\log-$(Get-Date -Format 'yyyyMMdd').txt" -Tail 50

# IIS log
Get-Content "C:\inetpub\logs\LogFiles\W3SVC<ID>\u_ex$(Get-Date -Format 'yyMMdd').log" -Tail 30

# Stdout log khi crash startup
Get-Content "C:\inetpub\apps\SolutionErp\Api\Logs\stdout_*.log" -Tail 30

Health check

# Từ server
curl http://localhost:5443/health/live
curl http://localhost:5443/health/ready

# Từ ngoài
curl https://api.huypham.vn/health/ready

Let's Encrypt cert — win-acme

Check trạng thái

# Mở win-acme interactive
& "C:\tools\win-acme\wacs.exe"
# Menu > Manage renewals > list — xem 3 cert + next renew date

# Hoặc file:
Get-Content "C:\ProgramData\win-acme\Production\$(hostname)\Renewals\*.renewal.json"

Cert hết hạn emergency

# Force renew 1 cert
& "C:\tools\win-acme\wacs.exe" --renew --force --id {renewal-id}

# Full re-issue nếu renewal fail:
& "C:\tools\win-acme\wacs.exe"  # interactive → 'N' create new
# Chọn: HTTP validation, web root = site physical path, auto install IIS

Gotcha: Shared runner với VIETREPORT → win-acme HTTP challenge cần .well-known/acme-challenge/ accessible qua HTTP (port 80). Rule HTTP→HTTPS redirect trong web.config PHẢI exclude path này:

<rule name="Redirect to HTTPS" stopProcessing="true">
  <match url="(.*)" />
  <conditions>
    <add input="{HTTPS}" pattern="off" />
    <add input="{REQUEST_URI}" pattern="^/\.well-known/" negate="true" />
  </conditions>
  <action type="Redirect" url="https://{HTTP_HOST}/{R:1}" />
</rule>

Gitea Actions runner (NSSM service)

Status

# NSSM service name: gitea-runner (shared với VIETREPORT)
Get-Service gitea-runner
nssm status gitea-runner

# Restart
Restart-Service gitea-runner

# Log
Get-Content "C:\tools\gitea-runner\logs\act_runner.log" -Tail 50

Token rotate (nếu runner disconnected)

# Stop service
Stop-Service gitea-runner

# Re-register qua Gitea admin UI → Actions → Runners → get new registration token
& "C:\tools\gitea-runner\act_runner.exe" register `
    --instance https://git.baocaogiaoduc.vn `
    --token <new-token> `
    --no-interactive

# Start lại
Start-Service gitea-runner

LibreOffice headless (PDF / docx converter)

Check install

& "C:\Program Files\LibreOffice\program\soffice.exe" --version
# → LibreOffice 25.8.6.x

Test convert manual

# Tạo temp dir isolated (mô phỏng per-request pattern của LibreOfficeDocumentConverter)
$work = New-Item -ItemType Directory -Path "$env:TEMP\lo-test-$(Get-Random)"
$userInst = "$work\userinst"

& "C:\Program Files\LibreOffice\program\soffice.exe" `
    --headless `
    "-env:UserInstallation=file:///$($userInst.Replace('\', '/'))" `
    --convert-to pdf `
    --outdir $work `
    "C:\path\to\test.docx"

# Output: $work\test.pdf
ls $work
Remove-Item -Recurse -Force $work

Prod fail patterns

• 60s timeout → PDF lớn (>100 page) có thể quá. Xem LibreOfficeDocumentConverter — tăng timeout nếu cần
• Locked font fallback → Be Vietnam Pro missing → text render hỏng. Install font trên server
• Concurrent request lock → mỗi request 1 UserInstallation dir riêng → tránh lock

Debug playbook — prod error

HTTP 500 all site

Xem gotcha #25 (docs/gotchas.md):

# Likely config lock:
& "$env:SystemRoot\system32\inetsrv\appcmd.exe" list config -section:system.webServer/webSocket
# → overrideMode="Deny" → fix:
& "$env:SystemRoot\system32\inetsrv\appcmd.exe" unlock config -section:system.webServer/webSocket

HTTP 502 Bad Gateway (Admin/User → API)

1. Check API up: curl http://localhost:5443/health/live
   - Down → restart API site + check stdout log
2. Check ARR enabled: IIS Manager > server level > Application Request Routing
   - "Enable proxy" phải tick
3. Check URL Rewrite rule fe web.config
   - action type="Rewrite" url="http://localhost:5443/{R:0}"

SignalR 401 (WebSocket connect fail)

Xem gotcha #26:

1. FE console: check ?access_token= query có trong negotiate URL không
2. BE log: JwtBearer OnMessageReceived có fire cho /hubs/* không
3. IIS WebSocket module: Install-WindowsFeature Web-WebSockets (đã có)
4. Section unlock: appcmd unlock config -section:system.webServer/webSocket

Login "Network Error"

Xem docs/gotchas.md CORS + HTTPS redirect:

1. User gõ http://admin.huypham.vn → không redirect → CORS block
2. Fix: SPA web.config PHẢI có HTTP→HTTPS rule (đã có)
3. Test: curl -I http://admin.huypham.vn → expect 301 Location: https://...

DB connection fail

# 1. SQL service up?
Get-Service MSSQL* 

# 2. TCP enabled?
Import-Module SqlServer
# Hoặc check registry:
Get-ItemProperty "HKLM:\SOFTWARE\Microsoft\Microsoft SQL Server\MSSQL*.SQLEXPRESS\MSSQLServer\SuperSocketNetLib\Tcp"

# 3. vrapp login OK?
sqlcmd -S .\SQLEXPRESS -U vrapp -P <pw> -Q "SELECT DB_NAME()"
# Expect: SolutionErp

# 4. appsettings connection string (qua Gitea secrets)
# Check C:\inetpub\apps\SolutionErp\Api\appsettings.Production.json có ConnectionStrings:DefaultConnection

Deploy steps (CI/CD xanh)

Gitea Actions workflow: .gitea/workflows/deploy.yml. Flow:

Push to main
  → Runner pick up job
  → checkout repo
  → setup .NET 10 + Node 20
  → npm ci (fe-admin + fe-user, rolldown native binding OK nếu fresh node_modules)
  → dotnet restore + publish
  → npm run build (fe-admin + fe-user)
  → render appsettings.Production.json từ secrets (JWT_SECRET, DB_CONNECTION)
  → stop app pool SolutionErp-Api
  → xcopy publish → C:\inetpub\apps\SolutionErp\{Api,Admin,User}
  → start app pool
  → curl /health/ready → must be 200 trong 30s
  → report status

Manual deploy (emergency)

# Local build
dotnet publish src/Backend/SolutionErp.Api -c Release -o .\publish\api
cd fe-admin; npm ci; npm run build; cd ..
cd fe-user;  npm ci; npm run build; cd ..

# Scp sang server (cần plink/pscp hoặc rsync)
scp -r .\publish\api\*           user@server:C:/inetpub/apps/SolutionErp/Api/
scp -r .\fe-admin\dist\*         user@server:C:/inetpub/apps/SolutionErp/Admin/
scp -r .\fe-user\dist\*          user@server:C:/inetpub/apps/SolutionErp/User/

# Trên server:
Restart-WebAppPool -Name "SolutionErp-Api"
curl http://localhost:5443/health/ready

Backup + recovery

# DB backup (script sẵn, chưa schedule):
& "C:\inetpub\apps\SolutionErp\scripts\backup-sql.ps1"
# Output: backup/SolutionErp_<ts>.bak (compressed + retention 30d)

# Schedule daily 03:00:
schtasks /create /tn "SolutionErp Backup" `
    /tr "powershell -ExecutionPolicy Bypass -File C:\inetpub\apps\SolutionErp\scripts\backup-sql.ps1" `
    /sc DAILY /st 03:00 /ru SYSTEM

Restore: xem docs/guides/runbook.md.

Rotate credentials (Phase 5.1 backlog)

• SQL sa password (rotate)
• SQL vrapp password (update Gitea secret DB_CONNECTION + appsettings.Production.json)
• JWT secret (update Gitea secret JWT_SECRET, next deploy sẽ lan tỏa. Tất cả token cũ invalid)
• Gitea runner registration token (re-register service)
• Admin default Admin@123456 (đổi qua /system/users admin UI ngay sau deploy)
