### RustDesk Pro - Install Additional Relay Servers with Geo Location using docker
|
||
|
||
You can have several relay servers running across the globe and leverage GeoLocation to use the closest relay server, giving you a faster experience when connecting to remote computers.
|
||
|
||
> You will need the private key pair `id_ed25519` and `id_ed25519.pub`.
|
||
|
||
1 - If docker is already installed, connect to your server via SSH and create a volume for hbbr.
|
||
|
||
```
|
||
# docker volume create hbbr
|
||
```
|
||
|
||
The volume hbbr should be located in `/var/lib/docker/volumes/hbbr/_data`.
|
||
|
||
2 - Copy the private key pair to the volume location, in this case we will use SCP to copy the files.
|
||
|
||
The command syntax is `scp <path/filename> username@server:</destination/path>`.
|
||
|
||
```
|
||
# scp id_ed25519 root@100.100.100.100:/var/lib/docker/volumes/hbbr/_data
|
||
# scp id_ed25519.pub root@100.100.100.100:/var/lib/docker/volumes/hbbr/_data
|
||
```
|
||
|
||
3 - Deploy the hbbr container using the volume previously created. This volume has the private key pair needed to run your private relay server.
|
||
|
||
```
|
||
# sudo docker run --name hbbr -v hbbr:/root -td --net=host rustdesk/rustdesk-server hbbr -k _
|
||
```
|
||
|
||
4 - Check the running logs to verify that hbbr is running using your key pair.
|
||
|
||
```
|
||
# docker logs hbbr
|
||
|
||
INFO [src/common.rs:121] **Private key comes from id_ed25519**
|
||
NFO [src/relay_server.rs:581] Key: XXXXXXXXXXXXXXXXXXXXX
|
||
INFO [src/relay_server.rs:60] #blacklist(blacklist.txt): 0
|
||
INFO [src/relay_server.rs:75] #blocklist(blocklist.txt): 0
|
||
INFO [src/relay_server.rs:81] Listening on tcp :21117
|
||
```
|
||
|
||
Depending on your OS, you might want to block/allow IPs using a firewall.
|
||
|
||
In our case, running Ubuntu we want to allow any TCP connections, to ports 21117 and 21119.
|
||
|
||
```
|
||
# sudo ufw allow proto tcp from any to any port 21117,21119
|
||
```
|
||
|
||
**Enable the firewall**
|
||
```
|
||
# sudo ufw enable
|
||
```
|
||
|
||
**Check the status**
|
||
```
|
||
# ufw status
|
||
|
||
Status: active
|
||
|
||
To Action From
|
||
-- ------ ----
|
||

|
||
21117,21119/tcp (v6) ALLOW Anywhere (v6)
|
||
```
|

### Configure RustDesk Pro for Geo Location using Web Console
|
||
|
||
#### Register and Download the GeoLite2 City database file
|
||
|
||
To use geo location, hbbs needs access to the MaxMind GeoLite2 City database. The database is free and you can register to download the file and get an API key.
|
||
|
||
Start by creating an account (if you don’t have one) by going to the [website](https://www.maxmind.com/en/account/login).
|
||
Go to `Download Databases` and download GeoLite2 City, choose the gzip file and you should have the `mmdb` file when decompressing it.
|
||
|
||

|
||
|
||
If you installed RustDesk Pro using the installation script on a Linux machine, the `mmdb` file needs to be moved to `/var/lib/rustdesk-server/`.
|
||
|
||
For Docker installations the file should be in the volume you mapped when deploying the container mapped to `/root`.
|
||
|
||
#### Get an API key to automate the process - Linux servers
|
||
|
||
You need to update this file regularly and we can use a cronjob to do that. You will need an API key to access the download link which is free.
|
||
|
||
Go to `Manage License Keys` and generate a new license key. <br>
|
||
<img width="500" alt="image" src="https://github.com/rustdesk/doc.rustdesk.com/assets/642149/632aeb33-4f5d-4a31-9010-38e01c22d3c9">

|
||
|
||
You can automate the [download process](https://dev.maxmind.com/geoip/updating-databases) in a few ways, but you add the following command to your crontab replacing {Your Access Key} with the API key you got from the previous step.
|
||
|
||
```
|
||
/usr/bin/curl -L --silent 'https://download.maxmind.com/app/geoip_download?edition_id=GeoLite2-City&license_key={Your Access Key}&suffix=tar.gz' | /bin/tar -C '/var/lib/rustdesk-server/' -xvz --keep-newer-files --strip-components=1 --wildcards '*GeoLite2-City.mmdb'
|
||
```
|
||
|
||
#### Change settings in RustDesk Pro Web Console
|
||
|
||
Add your relay server IP addresses to the the Relay Server List, using just the IP address. **Do not add the port.** <br>
|
||
<img width="500" alt="image" src="https://github.com/rustdesk/doc.rustdesk.com/assets/642149/c4452ba4-5e1d-437a-ae1d-fc0070bfa26c">
|
||
|
||
Add a Geo Override but adding the server IP address and the coordinates where the server is located. <br>
|
||
<img width="500" alt="image" src="https://github.com/rustdesk/doc.rustdesk.com/assets/642149/41c558e3-423b-4296-90d3-cb0769f4a369">
|
||
|
||
Click `Reload Geo` and your list should look similar to this. <br>
|
||
<img width="500" alt="image" src="https://github.com/rustdesk/doc.rustdesk.com/assets/642149/5a0d39a9-4fec-46b4-a7a2-7ed38b6baeb7">
|
||
|
||
To confirm the results, check your hbbs logs when clicking `Reload Geo`, you should see a message showing the relay server IP addresses and their coordinates.
|
||
|
||
> If you are running RustDesk Pro on a Linux machine use the command `RUST_LOG=debug ./hbbs` to view the logs. If you are running on a Docker container user `docker logs hbbs`.
|
||
|
||
```
|
||
RUST_LOG=debug ./hbbs
|

|
||
```
|
||
|
||
You can also confirm the relay requests directly on your hbbr instances, simply by checking the container logs.
|
||
|
||
```
|
||
# docker logs hbbr
|
||
|
||

|
||
INFO [src/relay_server.rs:442] Both are raw
