# GeoIP Database Updater Script
|
|
|
|
This script, automates the process of checking for new releases of GeoIP
|
|
databases on GitHub, downloading them if they're not already present, and
|
|
updating the local database files for use.
|
|
|
|
## Prerequisites
|
|
|
|
Ensure `wget` and `curl` are installed on your system.
|
|
|
|
## Setup Instructions
|
|
|
|
### 1. Create the Destination Directory
|
|
|
|
```bash
|
|
sudo mkdir -p /usr/local/share/GeoIP
|
|
```
|
|
|
|
### 2. Create a Group for GeoIP Users
|
|
|
|
Create a group to manage access to the GeoIP data.
|
|
|
|
```bash
|
|
sudo groupadd geoipusers
|
|
```
|
|
**Note: Log out and back in for the group change to take effect.**
|
|
|
|
### 3. Set Permissions and Ownership
|
|
|
|
Change the group ownership of the `/usr/local/share/GeoIP` directory to
|
|
`geoipusers`, and set the appropriate permissions.
|
|
|
|
```bash
|
|
sudo chown :geoipusers /usr/local/share/GeoIP
|
|
sudo chmod 775 /usr/local/share/GeoIP
|
|
```
|
|
|
|
### 4. Add Your User to the GeoIP Users Group
|
|
|
|
Add your user account to the `geoipusers` group to allow script execution and
|
|
access to the GeoIP directory.
|
|
|
|
```bash
|
|
sudo usermod -a -G geoipusers $USER
|
|
```
|
|
|
|
*Note: You may need to log out and log back in for the group changes to take effect.*
|
|
|
|
### 5. Install the Script
|
|
|
|
Copy the script to a globally accessible location and ensure it is executable:
|
|
|
|
```bash
|
|
sudo cp geoip_updater.sh /usr/local/bin/
|
|
sudo chown :geoipusers /usr/local/bin/geoip_updater.sh
|
|
sudo chmod +x /usr/local/bin/geoip_updater.sh
|
|
```
|
|
|
|
### 6. Schedule the Script in Crontab
|
|
|
|
Edit your crontab to run the script automatically:
|
|
|
|
```bash
|
|
crontab -e
|
|
```
|
|
|
|
Add the following line to schedule the script to run daily at 2 AM:
|
|
|
|
```bash
|
|
0 2 * * * /usr/local/bin/geoip_updater.sh >> /var/log/geoip_update.log 2>&1
|
|
```
|
|
|
|
### 7. Prepare the Log File
|
|
|
|
Make sure the script can write to the log file:
|
|
|
|
```bash
|
|
sudo touch /var/log/geoip_update.log
|
|
sudo chown :geoipusers /var/log/geoip_update.log
|
|
sudo chmod 664 /var/log/geoip_update.log
|
|
```
|
|
|
|
## Running the Script
|
|
|
|
The script will run as scheduled in the crontab. You can also execute it
|
|
manually at any time:
|
|
|
|
```bash
|
|
/usr/local/bin/geoip_updater.sh
|
|
```
|
|
|
|
## Troubleshooting
|
|
|
|
- Ensure the script is executable and the `/var/log/geoip_update.log` file is writable.
|
|
- Verify the crontab entry if the script does not run as expected.
|
|
- Check the log file `/var/log/geoip_update.log` for errors if the script fails.
