# Sysadmin Session Summary
## Date: 2025-11-23
## Host: git-repro (Gitea LXC)
## Session Type: Configuration and Backup Setup

---

## Session Overview

This session focused on completing the Gitea configuration for external access via Pangolin tunnel and establishing automated backup procedures.

---

## Tasks Completed

### 1. Gitea Domain Configuration Fix

**Issue:** Gitea login was returning 404 errors when accessed via the Pangolin tunnel domain.

**Root Cause:** The Gitea configuration had the internal IP address (100.120.125.113) set for `DOMAIN`, `ROOT_URL`, and `SSH_DOMAIN` instead of the external domain.

**Solution Applied:**
Updated `/etc/gitea/app.ini` with the following settings in the `[server]` section:

```ini
[server]
SSH_DOMAIN = git.pdmarf.co.uk
DOMAIN = git.pdmarf.co.uk
HTTP_PORT = 3000
ROOT_URL = https://git.pdmarf.co.uk/
```

**Verification:**
- Gitea service restarted successfully
- Login via https://git.pdmarf.co.uk now works correctly
- AppURL correctly shows: https://git.pdmarf.co.uk/

---

### 2. Pangolin Container Restart

**Action:** Restarted the Pangolin docker container to ensure the tunnel proxy was properly forwarding requests to the updated Gitea configuration.

**Result:** External access via git.pdmarf.co.uk confirmed working.

---

### 3. Automated Database Backup System

**Implementation Details:**

**Backup Script:** `/usr/local/bin/gitea-backup.sh`
```bash
#!/bin/bash
BACKUP_DIR="/var/backups/gitea"
DATE=$(date +%Y%m%d-%H%M%S)

mkdir -p $BACKUP_DIR

# Backup the database
cp /var/lib/gitea/data/gitea.db "$BACKUP_DIR/gitea.db-$DATE"

# Compress
gzip "$BACKUP_DIR/gitea.db-$DATE"

# Keep only last 7 days
find $BACKUP_DIR -name "*.gz" -mtime +7 -delete

echo "Gitea backup completed: $BACKUP_DIR/gitea.db-$DATE.gz"
```

**Cron Schedule:**
```
0 2 * * * /usr/local/bin/gitea-backup.sh
```
- Runs daily at 2:00 AM
- 7-day retention policy
- Backups stored in `/var/backups/gitea/`

**Backup Location:** `/var/backups/gitea/`

---

### 4. Backup/Restore Testing

**Test Performed:** Verified backup and restore process works correctly.

**Verification Steps:**
1. Manual backup execution confirmed working
2. Backup file created with timestamp: `gitea.db-20251123-174012.gz`
3. Compression working (original database compressed to ~33KB)
4. Restore procedure documented and tested

## Files Modified This Session

1. `/etc/gitea/app.ini` - Updated DOMAIN, ROOT_URL, SSH_DOMAIN
2. `/usr/local/bin/gitea-backup.sh` - Created backup script
3. `/var/spool/cron/crontabs/root` - Added backup cron job

---

## Recommendations for Future Sessions

1. **Off-site Backup:** Consider syncing backups to remote storage (S3, rsync to another server)
2. **Repository Backup:** The current backup only covers the database; consider backing up `/home/git/gitea-repositories/` as well
3. **Monitoring:** Set up alerting for backup failures
4. **Full Backup Script:** Create a comprehensive backup that includes:
   - Database (`/var/lib/gitea/data/gitea.db`)
   - Repositories (`/home/git/gitea-repositories/`)
   - Configuration (`/etc/gitea/app.ini`)
   - Custom files (`/var/lib/gitea/custom/`)
