Git

Client-side Installation

In the client,

$ apt-get install git-core 
$ git config --global user.name "GivenName Surname" 
$ git config --global user.email user@email.address

Server-side Installation

In the server,

$ apt-get install git

Gitolite

Add User to Manage Gitolite

Add user to manage gitolite

$ adduser \
  --system \
  --shell /bin/bash \
  --gecos 'git version control' \
  --group \
  --disabled-password \
  --home /home/git \
  git

Adding system user `git' (UID 108) ...
Adding new group `git' (GID 110) ...
Adding new user `git' (UID 108) with group `git' ...
Creating home directory `/home/git' ...

Create SSH key

$ ssh-keygen -t rsa

/home/username/.ssh/some_git_rsa [ENTER] [ENTER]

Transfer SSH Keys to Server

$ ssh-copy-id '-p PORT_NUMBER -i /home/user/.ssh/some_git_rsa.pub git_user@host'

If it doesn't work because the user is the only user who can access the server with his/her ssh key so accessing with git_user doesn't work.

$ scp -P PORT ~/.ssh/some_git_rsa.pub user@host:

Log in with the user account

$ ssh -p PORT user@host
$ mv some_git_rsa.pub git.pub

Setup

$ su - git 
$ cd ~ 
$ echo "PATH=$HOME/bin:$PATH" >> ~/.bashrc

don't need these 2 lines

$ mkdir .ssh 
$ cat /home/user/git.pub >> /home/git/.ssh/authorized_keys

$ exit

Gitolite Installation

$ sudo -i 
$ apt-get install gitolite
[ENTER] -> :q to exit
$ exit

Setup git User

$ su - git
$ gl-setup /home/user/git.pub

$ vim /etc/ssh/sshd_config

Add git to the allowed user

AllowUsers user git

Restart ssh

$ service ssh restart

Test

Testing (from user local machine)

$ ssh -p PORT_NUMBER git@host

Having many keys?

$ ssh -p PORT_NUMBER -i ~/.ssh/user@host1.pub git@host

For debugging

$ ssh -p PORT_NUMBER -vT git@host

$ mkdir some-dir 
$ cd some-dir 
$ git clone git@host:gitolite-admin

Or if you use a specific port,

$ git clone ssh://git@host:PORT_NUMBER/gitolite-admin

Add Git User (through Gitolite)

Adding User

$ cd gitolite-admin/keydir 
$ mkdir user_name 
$ cp -p ~/.ssh/user@host1.pub .
$ cp -p ~/.ssh/user@host2.pub .
$ git add user@host1.pub 
$ git commit -a -m "users added: user@host1 and user@host2" 
$ git push

Usage

Host Info Config using SSH_Config

Create ~/.ssh/config file and edit.

Host host.name
  Hostname host.name
  Port 1111

Host another.host.name
  Hostname another.host.name
  Port 2222

Host host1
  Hostname host.name
  Port 1111
  User git
  IdentityFile ~/.ssh/git_rsa.pub

Host user-host2
  Hostname host2.name
  Port 1234
  User user
  IdentityFile ~/.ssh/user@localhost1.pub

Host user-host3
  Hostname host3.com
  Port 1122
  User user
  IdentityFile ~/.ssh/user@localhost1.pub

To use this info,

$ git clone git@host1:repo-name 
# it will use 'git' as a user and access the server 'host.name' using the port nubmer 1111.

$ git clone git@host1:repo-name 
# it will use 'user' as a user and access the server 'host2.name' using the port nubmer 1234.

Push to Specific Host

$ git push git@host1:repo-name master
