Github helped popularize git and its concepts to many. Nevertheless, it involves making public all the codes you want to host, unless you buy a fairly expensive subscription, and for a limited number of projects. Moreover, Github is not open, and it is therefore necessary to give it some trust to store its projects.
Several solutions exist to host a git server on his personal server. For example, Gitlab aims to become equal to Github, with a graphical interface and many tools; thereby, it is very large and relatively heavy for a small server.
Here we will see how to install Gitolite, which provides a very light and functional git server, in order to synchronizing repositories between different working stations.
Creating git user on the server
First, we will create on the server a
git user, which will be needed:
sudo adduser git
Once connected to
git on the server, we create a
bin directory that will contain binaries, that we then add to the
cd ~ mkdir bin PATH=$PATH:~/bin PATH=~/bin:$PATH
Creating an authentication key
In order to connect to Gitolite, we will used SSH key-based authentication, both simpler and more secure than HTTP. If you do not already have a key, it is necessary to create one. For this, we will used
cd ~/.ssh ssh-keygen -t ed25519 -a 100
When the path is requested, enter your username
<user>. The password is optional: if you choose one, it will be asked each time a git command is requesting the server.
We then send the public key on the server:
cat ~/.ssh/<user>.pub | ssh git@<hostname> -p <port> 'umask 0077; mkdir -p .ssh; cat >> <user>.pub'
Finally, we create a
~/.ssh/config file that contains the following information:
Host git HostName <hostname> Port <port> User git IdentityFile ~/.ssh/<user>
Back to the user
git on the server, we can now install Gitolite:
cd ~ git clone git://github.com/sitaramc/gitolite gitolite/install -ln gitolite setup -pk ~/<user>.pub
Locally, you can now check that everything works well with
ssh git. This should return something like:
PTY allocation request failed on channel 0 hello <user>, this is git@<hostname> running gitolite3 v3.6.5-9-g490b540 on git 2.1.4 R W gitolite-admin R W testing
That’s all ! Now, if you want to clone a
repo directory, simply run the command
git clone git:repo. The
fetch … will operate without password.
The main originality of Gitolite is that its configuration system uses a specific git repository. To configure Gitolite, simply clone the
git clone git:gitolite-admin
This repository contains a
conf/gitolite.conf file that lists the directories and permissions, and a
keydir folder containing the users public keys (your
<user>.pub key, provided during the installation, is already there).
For example, to add a
project repository, just edit
conf/gitolite.conf to add:
repo project RW+ = <user>
To apply all changes,
push those files on the server. Don’t hesitage to check the very complete Gitolite documentation.
