# GeoIP Database Updater Script

This script, automates the process of checking for new releases of GeoIP
databases on [GitHub](https://github.com/merkez/maxmind-databases), downloading them if they're not already present, and
updating the local database files for use.

## Prerequisites

Before proceeding, ensure that `wget` and `curl` are installed on your system,
as they are required for the script to download files and check URLs.

## Setup Instructions

### Using `setup.sh` Script

1. **Execute `setup.sh` as Normal User**:
    - Run the setup script as a normal user **without** sudo privileges to perform operations like creating directories, changing permissions, and editing the crontab. It will ask you for the password when needed.
      ```bash
      ./setup.sh
      ```
    - This approach ensures that the crontab entries are added to the current user's crontab, not the root's crontab.

2. **Verify Crontab Entry**:
    - After running `setup.sh`, verify that the crontab entries have been added correctly by listing the current user's crontab:
      ```bash
      crontab -l
      ```
    - You should see three new entries for running `geoip_updater.sh` with specific dates.


## Manual Execution

After setup, the `geoip_updater.sh` script will run automatically according to the schedule set in the crontab. However, you can also run the script manually at any time by executing:

```bash
/usr/local/bin/geoip_updater.sh
```

Optionally, you can specify a date as an argument to manually check and download the database for a specific date:

```bash
/usr/local/bin/geoip_updater.sh YYYY-MM-DD
```

## Troubleshooting

- If the script does not run as scheduled, ensure that the `crontab` entries are set correctly and that `geoip_updater.sh` is executable.
- Check the log file `/var/log/geoip_update.log` for any errors or messages output by the script.
