# Running headscale on Linux
## Requirements
- Ubuntu 20.04 or newer, Debian 11 or newer.
## Goal
Get Headscale up and running.
This includes running Headscale with SystemD.
## Migrating from manual install
If you are migrating from the old manual install, the best thing would be to remove
the files installed by following [the guide in reverse](./running-headscale-linux-manual.md).
You should _not_ delete the database (`/var/headscale/db.sqlite`) and the
configuration (`/etc/headscale/config.yaml`).
## Installation
1. Download the lastest Headscale package for your platform (`.deb` for Ubuntu and Debian) from [Headscale's releases page]():
```shell
wget --output-document=headscale.deb \
https://github.com/juanfont/headscale/releases/download/v<HEADSCALE VERSION>/headscale_<HEADSCALE VERSION>_linux_<ARCH>.deb
```
2. Install Headscale:
```shell
sudo dpkg --install headscale.deb
```
3. Enable Headscale service, this will start Headscale at boot:
```shell
sudo systemctl enable headscale
```
4. Configure Headscale by editing the configuration file:
```shell
nano /etc/headscale/config.yaml
```
5. Start Headscale:
```shell
sudo systemctl start headscale
```
6. Check that Headscale is running as intended:
```shell
systemctl status headscale
```
## Using Headscale
### Create a user
```shell
headscale users create myfirstuser
```
### Register a machine (normal login)
On a client machine, run the `tailscale` login command:
```shell
tailscale up --login-server <YOUR_HEADSCALE_URL>
```
Register the machine:
```shell
headscale --user myfirstuser nodes register --key <YOUR_MACHINE_KEY>
```
### Register machine using a pre authenticated key
Generate a key using the command line:
```shell
headscale --user myfirstuser preauthkeys create --reusable --expiration 24h
```
This will return a pre-authenticated key that is used to
connect a node to `headscale` during the `tailscale` command:
```shell
tailscale up --login-server <YOUR_HEADSCALE_URL> --authkey <YOUR_AUTH_KEY>
```
