Simple setup for starting with git

Andy Wenk - 02.10.2009

This is a note to myself how to create a git repository. I am assuming to have root access to an own server. In this case it's (again) a Debian Linux machine with running Lenny.

SSH keys

---

The clone, pull and push process uses ssh, so it is necessary to create keys. Use rsa instead of dsa because it's more secure. And don't forget to set a passphrase!

On the local machine

$ ssh-keygen -t rsa

Put the public key the machine you will place the git repositorys and add them to the authorized_keys

Install git

---

$ aptitude install git-core

Create a repository on the server

---

Here all the repos go in

$ mkdir /var/lib/git

A new repository

$ mkdir /var/lib/git/therepo

$ cd /var/lib/git/therepo/

$ git init

Initialized empty Git repository in /var/lib/git/therepo/.git/

Unless one file is in the repository, you cannot clone it

$ vi README

$ git add README

$ git commit README

Created initial commit fb17959: initialize

0 files changed, 0 insertions(+), 0 deletions(-)

create mode 100644 README

Change the rights for the repo to an existing user

$ chown -R myuser:users /var/lib/git/therepo

configure git on the local machine

---

Install git

$ aptitude install git-core

Setup some global info

$ git config --global user.name "My Name"

$ git config --global user.email "my@email-address.com"

Add the origin

$ git remote add origin ssh://user@server.com/var/lib/git/therepo

Now clone the repo. You can set a new repo name. If not, the remote repo name will be used to create a folder.

$ git clone ssh://user@server.com/var/lib/git/therepo [local_repo_name]

Initialized empty Git repository in /home/user/git/therepo/.git/

remote: Counting objects: 3, done.

remote: Total 3 (delta 0), reused 0 (delta 0)

Receiving objects: 100% (3/3), done.

Adding or edit files in the local repo

---

Start to do some work and add them to your local repo.

$ touch testfile

$ git add testfile

$ git commit tesfile

Created commit f0ed9ad: testfile

0 files changed, 0 insertions(+), 0 deletions(-)

create mode 100644 testfile

Here you added some files to the repo and commited them to your local branch - not to the remote branch! To do this step, you have to push them. Remember that we set the origin allready.

$ git push origin master

Counting objects: 3, done.

Compressing objects: 100% (2/2), done.

Writing objects: 100% (2/2), 247 bytes, done.

Total 2 (delta 0), reused 0 (delta 0)

To ssh://user@server.com/var/lib/git/therepo

fb17959..f0ed9ad master -> master

If you want to recieve the actual repo or just want to check if everything is update here, use git pull.

$ git pull

Already up-to-date.

That's it - have fun with git!
