 ====== Git ======
+  * [[GitServerShared|Git: create your own git server, but sharing access to all the repositories]]
-===== Intro =====
-This turorial will show how to create a remote git server but
-every user you give permissions can contribute to every
-git project in the server.
-To create a git server in which every project can see only the
-projects they have assigned, I suppose there are other solutions,
-but definitely this solution will not work, because in this
-tutorial every commit will be made by a generic git user that
-can read and write in every directory.
-===== Set up a git server =====
-First, install git on your machine. In my case, because it's an
-ubuntu, I've run:
-<code>
-sudo apt-get install git
-</code>
-===== Create git user =====
-I prefer to create a "normal" **git** user instead a system one.
-If you prefer to create a system user, just add the **--system**
-option to the command:
-The **--create-home** option is needed because there we will be
-storing the public keys of the users of the repository.
-<code>
-useradd --create-home --user-group git
-</code>
-===== Enter as git user and add remote public keys =====
-<code>
-~$ mkdir .ssh
-~$ chmod o=,g= .ssh
-~$ cd .ssh
-~/.ssh$ touch authorized_keys
-~/.ssh$ chmod o=,g= authorized_keys
-</code>
-===== Add the keys of the different users of the git repository =====
-<code>
-~$ cat public_key_of_first_user.pub >> .ssh/authorized_keys
-~$ rm public_key_of_first_user.pub # you can remove the public key afterwards if you want
-</code>
-===== Verification: in the first_user computer check that you can log in as git user to the remote computer =====
-Check that you can make a ssh to the remote computer with no password request:
-<code>
-rluna@asustao:~$ ssh git@192.168.0.21
-The authenticity of host '192.168.0.21 (192.168.0.21)' can't be established.
-ED25519 key fingerprint is SHA256:PvSiThCnDq8pNOXyVgsq5vsXLME6oYIbCs0v5urvcpE.
-This key is not known by any other names
-Are you sure you want to continue connecting (yes/no/[fingerprint])? yes
-Warning: Permanently added '192.168.0.21' (ED25519) to the list of known hosts.
-The programs included with the Ubuntu system are free software;
-the exact distribution terms for each program are described in the
-individual files in /usr/share/doc/*/copyright.
-Ubuntu comes with ABSOLUTELY NO WARRANTY, to the extent permitted by
-applicable law.
-git@ubuntu2004:~$
-</code>
-If this is step succeeds, you can continue.
-==== Create a directory for your repositories ====
-In the server computer, I've created a ```/var/git``` directory
-to hold the repositories.
-As root, do the following:
-<code>
-# mkdir /var/git
-# chown git:git /var/git
-# chmod g=rx,o= /var/git
-</code>
-The permissions are set 750 to allow the git user to do
-anything inside the directory, and the group members to
-allow other users to read the contents: this will allow
-us to create other users that can read this directory
-by adding them to the group of the git user.
-==== Create a repository ====
-To create a repository, log in as the git user and make
-a git init --bare:
-<code>
-git$ cd /var/git
-git$ mkdir repo1.git
-git$ cd repo1.git
-git$ git init --bare
-</code>
-Congrats! you have created your first repository.
-The .git extension of the directory is not needed, is
-just to make the url of the repository more cool.
-<code>
-usermod --shell /bin/false git
-</code>
