# A minimal Git server
|
|
|
|
This is a quick, no-nonsense guide on setting up a Git server on a VPS.
|
|
I am using Debian, but other operating systems should be easy to figure out.
|
|
|
|
## Create a user
|
|
|
|
Make a `git` user:
|
|
|
|
```
|
|
sudo adduser git
|
|
```
|
|
|
|
Switch to the `git` user:
|
|
|
|
```
|
|
sudo su -l git
|
|
```
|
|
|
|
## Configure secure access
|
|
|
|
Create a `.ssh` dir in the `git` user's home directory and make it only accessible by the `git` user:
|
|
|
|
```
|
|
mkdir ~/.ssh
|
|
chmod 700 ~/.ssh
|
|
```
|
|
|
|
Create an `authorized_keys` file in the `.ssh` folder, and make it accessible only by the `git` user:
|
|
|
|
```
|
|
touch .ssh/authorized_keys
|
|
chmod 600 `.ssh/authorized_keys`
|
|
```
|
|
|
|
Create a public/private key pair locally to authenticate a user on a machine to connect to the remote server:
|
|
|
|
```
|
|
ssh-keygen -t ed25519
|
|
```
|
|
|
|
And finally copy it into the (remote) `git` user's `.ssh/authorized_keys`, using `ssh-copy-id` or by giving the public key to the server administrator.
|
|
|
|
## Creating bare Git repositories
|
|
|
|
Create directories within git's home dir (nested paths are allowed) with the `.git` extension, for example `my-projects/my-repo.git` or just `my-repo.git`.
|
|
|
|
```
|
|
git init --bare repo.git
|
|
```
|
|
|
|
There now exists an empty Git repository on the remote server.
|
|
|
|
The remote can now be added to a local repository:
|
|
|
|
```
|
|
git remote add origin git@server:my-repo.git
|
|
git push -u origin main
|
|
```
|
|
|
|
# Connecting securely
|
|
|
|
Add an entry to your local `.ssh/config`:
|
|
|
|
```
|
|
Host myhost
|
|
HostName example.com
|
|
User git
|
|
IdentityFile ~/.ssh/id_ed25519
|
|
```
|
|
|
|
And connect once without Git to verify the host:
|
|
|
|
```
|
|
ssh myhost
|
|
```
|
|
|
|
---
|
|
|
|
Done!
