- Features disabled: Public registration, external avatars, update checker

---

### 3. Systemd Service Configuration

**Service File:** `/etc/systemd/system/gitea.service`

**Key Settings:**
- Type: Simple
- User/Group: gitea:gitea
- WorkingDirectory: `/var/lib/gitea`
- ExecStart: `/usr/local/bin/gitea web -c /etc/gitea/app.ini`
- Restart: Always
- WantedBy: multi-user.target (auto-start on boot)

**Service Management:**
```bash
systemctl daemon-reload      # Loaded service
systemctl enable gitea       # Enabled auto-start
systemctl start gitea        # Started service
systemctl status gitea       # Verified running
```

---

### 4. Nginx Reverse Proxy Setup

**Issue Encountered:** Default Nginx site was binding to `0.0.0.0:80`, preventing IP-specific binding.

**Resolution:** Removed `/etc/nginx/sites-enabled/default`

**Configuration:** `/etc/nginx/sites-available/git.firefrostgaming.com`

**Binding Strategy:**
- HTTP (80): `listen 74.63.218.202:80` → 301 redirect to HTTPS
- HTTPS (443): `listen 74.63.218.202:443 ssl http2`
- Proxy target: `http://127.0.0.1:3000`
- Max upload: 512M (for large repository pushes)

**Initial SSL:** Self-signed certificate (temporary for testing)
- Generated via OpenSSL
- Replaced by Let's Encrypt in Step 7

**Service Restart Required:**
- Issue: Port 80 still showing `0.0.0.0` binding after reload
- Cause: Nginx inherited sockets from previous config
- Fix: `systemctl restart nginx` (full restart cleared inherited sockets)
- Result: Ports 80 and 443 correctly bound to 74.63.218.202

---

### 5. DNS Configuration

**Provider:** Cloudflare  
**Zone:** firefrostgaming.com

**Record Added:**
- Type: A
- Name: git
- Value: 74.63.218.202
- Proxy Status: **DNS Only (Gray Cloud)** - Required for Let's Encrypt
- TTL: Auto

**Propagation Verification:**
```bash
nslookup git.firefrostgaming.com
# Result: 74.63.218.202 ✓
```

**Propagation Time:** ~2 minutes

---

### 6. Frostwall (UFW) Configuration

**Initial State:** No firewall active (Phase 0 cleanup removed iptables)

**Issue:** UFW installation removed conflicting packages:
- iptables-persistent (removed)
- netfilter-persistent (removed)

**Firewall Rules Applied:**
```bash
# Global SSH protection (prevent lockout)
ufw allow 22/tcp

# Primary gateway protection (existing services)
ufw allow in on ens3 to 63.143.34.217

# Gitea HTTP (Let's Encrypt validation + redirect)
ufw allow in on ens3 to 74.63.218.202 port 80 proto tcp

# Gitea HTTPS (web interface)
ufw allow in on ens3 to 74.63.218.202 port 443 proto tcp

# Enable firewall
ufw --force enable
```

**Active Rules:**
```
Status: active

To                              Action      From
--                              ------      ----
22/tcp                          ALLOW IN    Anywhere
63.143.34.217 on ens3           ALLOW IN    Anywhere
74.63.218.202 80/tcp on ens3    ALLOW IN    Anywhere
74.63.218.202 443/tcp on ens3   ALLOW IN    Anywhere
22/tcp (v6)                     ALLOW IN    Anywhere (v6)
```

**Security Model:** IP-specific rules (not blanket 0.0.0.0 rules)

---

### 7. SSL Certificate Deployment

**Tool:** Certbot with Nginx plugin

**Certificate Obtained:**
- Domain: git.firefrostgaming.com
- Provider: Let's Encrypt
- Certificate: `/etc/letsencrypt/live/git.firefrostgaming.com/fullchain.pem`
- Private Key: `/etc/letsencrypt/live/git.firefrostgaming.com/privkey.pem`
- Expires: May 9, 2026
- Auto-renewal: Enabled (certbot.timer systemd unit)

**Certbot Actions:**
- Validated domain ownership via HTTP-01 challenge
- Generated certificate
- Automatically updated Nginx configuration

## Issues Encountered & Resolutions

### Issue 1: Nginx Port Binding Conflict

**Problem:** Nginx was listening on `0.0.0.0:80` instead of `74.63.218.202:80`

**Root Cause:** Default Nginx site (`/etc/nginx/sites-enabled/default`) was binding to all interfaces

**Resolution:**
```bash
rm /etc/nginx/sites-enabled/default
nginx -t  # Test config
systemctl restart nginx  # Full restart (reload wasn't enough)
```

**Lesson Learned:** Always check for default configs that bind to 0.0.0.0

---

### Issue 2: Inherited Socket Bindings

**Problem:** After reload, port 80 still showed `0.0.0.0` binding

**Root Cause:** Nginx error log showed "using inherited sockets from 5;6"

**Resolution:** Full `systemctl restart nginx` instead of `reload`

**Lesson Learned:** Major configuration changes (IP binding changes) require restart, not just reload

---

### Issue 3: Gitea Installer Permissions

**Problem:** Web installer failed with "permission denied" writing to `/etc/gitea/app.ini`

**Root Cause:** Configuration directory/file owned by root, installer runs as gitea user

**Resolution:**
```bash
# Temporary permissions for installation
chown gitea:gitea /etc/gitea
chown gitea:gitea /etc/gitea/app.ini

# Lock down after installation
chmod 750 /etc/gitea
chmod 640 /etc/gitea/app.ini
```

**Lesson Learned:** Web installers need temporary write access, must be locked down post-install

---

### Issue 4: Self-Signed Certificate Missing

**Problem:** Nginx failed to start - self-signed certificate didn't exist

**Root Cause:** Ubuntu 22.04 doesn't include default self-signed cert

**Resolution:**
```bash
openssl req -x509 -nodes -days 365 -newkey rsa:2048 \
  -keyout /etc/ssl/private/ssl-cert-snakeoil.key \
  -out /etc/ssl/certs/ssl-cert-snakeoil.pem \
  -subj "/CN=git.firefrostgaming.com"
```

**Lesson Learned:** Generate temporary self-signed cert before Let's Encrypt

---

### Issue 5: Git Push Rejected (Divergent Branches)

**Problem:** `git push` failed - "remote contains work that you do not have locally"

**Root Cause:** Changes made via Gitea web interface not present in local repository

**Resolution:**
```bash
git config pull.rebase false  # Configure merge strategy
git pull origin master        # Download and merge remote changes
git push                      # Push merged result
```

**Lesson Learned:** Always pull before push if working from multiple locations

---

### Issue 6: Repeated Password Prompts

**Problem:** Git asking for username/password on every push/pull

**Root Cause:** Credential caching not configured

**Resolution:**
```bash
git config credential.helper store
git pull  # Enter password one last time - Git saves it
# Future operations use cached credentials
```

**Lesson Learned:** Configure credential helper early in workflow

---

**Git Operations:** ✅ Clone, push, pull all working  
**SSL Encryption:** ✅ HTTPS active with valid certificate

---

## Security Posture

### Application Layer

- ✅ Public registration disabled (admin-only account creation)
- ✅ Sign-in required to view (no public browsing)
- ✅ Gravatar disabled (no external service calls)
- ✅ Local mode enabled (all assets served locally)
- ✅ Strong password hashing (pbkdf2)
- ✅ Hidden email domain configured (noreply.git.firefrostgaming.com)

### Network Layer

- ✅ Gitea bound to localhost only (127.0.0.1:3000)
- ✅ All external access via Nginx reverse proxy
- ✅ IP-specific firewall rules (not blanket 0.0.0.0)
- ✅ Primary gateway unchanged (63.143.34.217 protected)
- ✅ SSL/TLS encryption on all external connections

### File System

- ✅ Service runs as non-root user (gitea:gitea)
- ✅ Configuration locked down (640 permissions)
- ✅ Sensitive files excluded from Git (.gitignore)
- ✅ Sanitized templates created for sharing

### Secrets Management

**Protected Secrets (NOT in Git):**
- `SECRET_KEY` - Application secret
- `INTERNAL_TOKEN` - API authentication
- `LFS_JWT_SECRET` - LFS authentication
- `JWT_SECRET` - OAuth2 token signing

**Public Template (IN Git):**
- `app.ini.template` with placeholders
- Safe to share/reference

## Lessons Learned

### What Worked Well

1. **Micro-block command format** - Small, focused command blocks made execution easier for accessibility needs
2. **Complete file paste** - Pasting entire config files vs line-by-line edits reduced errors
3. **IP isolation strategy** - Dedicated IP per service simplifies troubleshooting and security
4. **Checkpoint system** - Pausing for verification prevented cascading issues
5. **Sanitized templates** - Creating .gitignore and templates protected sensitive data
6. **Documentation-first approach** - Writing guides during deployment captured context

### Process Improvements for Next Service

1. **Check for default configs early** - Look for 0.0.0.0 bindings before configuring new services
2. **Use restart instead of reload** - For major config changes (IP bindings, site additions)
3. **Generate self-signed cert first** - Before attempting Let's Encrypt
4. **Configure Git credentials early** - Set up credential.helper at start of session
5. **Document as you go** - Don't wait until end to write documentation

### Carry Forward to Service 2

- ✅ Micro-block format confirmed effective
- ✅ IP isolation model validated
- ✅ UFW is now standard (replaced iptables from Phase 0)
- ✅ Full restart philosophy for major changes
- ✅ Git workflow established
- ✅ Security-first mindset maintained
