sudo su
backup from https://www.git-scm.com/book/en/v2/Git-on-the-Server-Setting-Up-the-Server
First, you create a git
user account and a .ssh
directory for that user.
$ sudo adduser git
$ su git
$ cd
$ mkdir .ssh && chmod 700 .ssh
$ touch .ssh/authorized_keys && chmod 600 .ssh/authorized_keys
Next, you need to add some developer SSH public keys to the authorized_keys
file for the git
user. Let’s assume you have some trusted public keys and have saved them to temporary files. Again, the public keys look something like this:
$ cat /tmp/id_rsa.john.pub
ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQCB007n/ww+ouN4gSLKssMxXnBOvf9LGt4L
ojG6rs6hPB09j9R/T17/x4lhJA0F3FR1rP6kYBRsWj2aThGw6HXLm9/5zytK6Ztg3RPKK+4k

dAv8JggJICUvax2T9va5 gsg-keypair
You just append them to the git
user’s authorized_keys
file in its .ssh
directory:
$ cat /tmp/id_rsa.john.pub >> ~/.ssh/authorized_keys
$ cat /tmp/id_rsa.josie.pub >> ~/.ssh/authorized_keys
$ cat /tmp/id_rsa.jessica.pub >> ~/.ssh/authorized_keys
Now, you can set up an empty repository for them by running git init
with the --bare
option, which initializes the repository without a working directory:
$ cd /srv/git
$ mkdir project.git
$ cd project.git
$ git init --bare
Initialized empty Git repository in /srv/git/project.git/
Then, John, Josie, or Jessica can push the first version of their project into that repository by adding it as a remote and pushing up a branch. Note that someone must shell onto the machine and create a bare repository every time you want to add a project. Let’s use gitserver
as the hostname of the server on which you’ve set up your git
user and repository. If you’re running it internally, and you set up DNS for gitserver
to point to that server, then you can use the commands pretty much as is (assuming that myproject
is an existing project with files in it):
# on John's computer
$ cd myproject
$ git init
$ git add .
$ git commit -m 'Initial commit'
$ git remote add origin git@gitserver:/srv/git/project.git
$ git push origin master
At this point, the others can clone it down and push changes back up just as easily:
$ git clone git@gitserver:/srv/git/project.git
$ cd project
$ vim README
$ git commit -am 'Fix for README file'
$ git push origin master
With this method, you can quickly get a read/write Git server up and running for a handful of developers.
You should note that currently all these users can also log into the server and get a shell as the git
user. If you want to restrict that, you will have to change the shell to something else in the /etc/passwd
file.
You can easily restrict the git
user account to only Git-related activities with a limited shell tool called git-shell
that comes with Git. If you set this as the git
user account’s login shell, then that account can’t have normal shell access to your server. To use this, specify git-shell
instead of bash
or csh
for that account’s login shell. To do so, you must first add the full pathname of the git-shell
command to /etc/shells
if it’s not already there:
$ cat /etc/shells # see if git-shell is already in there. If not...
$ which git-shell # make sure git-shell is installed on your system.
$ sudo -e /etc/shells # and add the path to git-shell from last command
Now you can edit the shell for a user using chsh <username> -s <shell>
:
$ sudo chsh git -s $(which git-shell)
Now, the git
user can still use the SSH connection to push and pull Git repositories but can’t shell onto the machine. If you try, you’ll see a login rejection like this:
$ ssh git@gitserver
fatal: Interactive git shell is not enabled.
hint: ~/git-shell-commands should exist and have read and execute access.
Connection to gitserver closed.
At this point, users are still able to use SSH port forwarding to access any host the git server is able to reach. If you want to prevent that, you can edit the authorized_keys
file and prepend the following options to each key you’d like to restrict:
no-port-forwarding,no-X11-forwarding,no-agent-forwarding,no-pty
The result should look like this:
$ cat ~/.ssh/authorized_keys
no-port-forwarding,no-X11-forwarding,no-agent-forwarding,no-pty ssh-rsa
AAAAB3NzaC1yc2EAAAADAQABAAABAQCB007n/ww+ouN4gSLKssMxXnBOvf9LGt4LojG6rs6h

Now Git network commands will still work just fine but the users won’t be able to get a shell. As the output states, you can also set up a directory in the git
user’s home directory that customizes the git-shell
command a bit. For instance, you can restrict the Git commands that the server will accept or you can customize the message that users see if they try to SSH in like that. Run git help shell
for more information on customizing the shell.
0) prerequisites :
- have a server running openssh with a static IP address and port 22 allowed
- have git installed. It's usually already there by default, otherwise run
$ sudo apt install git
1) create a git user
$ sudo adduser git
2) for more security, restrict the user git to have a limited shell :
$ sudo nano /etc/passwd
change git:x:1000:1000::/home/git:/bin/bash (details may change)
to git:x:1000:1000::/home/git:/usr/bin/git-shell
(or run which git-shell to see where it̢۪s installed)
3) create a directory where to put the git project, here called "project"
$ sudo mkdir -p /home/git/gitprojects/project.git
4) Initialise the repository
$ cd /home/git/gitprojects/project.git
$ git --bare init
5) You can now use the repository from a remote computer, connecting via ssh
$ git remote add origin git@static-IP-address:gitprojects/project.git
$ git push origin master
6) you can also clone
$ git clone git@static-IP-address:gitprojects/project.git
For all these operations, you will be asked for the password of the user "git" on the server
7) for more security and more convenience, you can also configure authentication by RSA keys
$ su git && cd ~
$ mkdir .ssh
$ nano .ssh/authorized_keys
paste here the RSA public keys of the users who are going to connect. Alternatively, if you have the key as a file, you can do
$ cat /tmp/id_rsa_foobar.pub >> ~/.ssh/authorized_keys
