Git

Installation

Redhat EL 6.0

Simple installation:

yum install git

Using git.hpc.ufl.edu

Request a group repository

As an example we'll use the awesome group, administrative user (set up by HPC staff) admin and a regular user student.

• Open a support ticket in the HPC Support] ticket system with a name like "Create an HPC Git repository for the "Awesome" group.
• List your projected git usage:

1. What group will be accessing it.
2. Who would be the group administrator (username).
3. How soon you need it set up.
4. How much space you need i.e. what type of content is going to be stored in the repository.
5. The uptime requirements i.e. whether the occasional downtime is acceptable.
6. Where the repository administrator's public ssh key can be found (you can paste it into the support ticket).

• Assuming that your usage pattern falls within the limits of our resources we'll create a repository 'awesome' on git.hpc.ufl.edu and configure it for the administrator. After that the administrator 'admin' can do the following:

admin@linux64

The admin user on a remote machine linux64 can do the following

• Check out the admin repository

git clone awesome@git.hpc.ufl.edu:gitosis-admin.git

• Add more users e.g. 'student' with a public key student.pub

cd gitosis-admin
cp ~/student.pub keydir/
git add keydir/*
git commit -m "added user student"
git push

• Create a new repository denovo for de novo assembly scripts and set access to users admin and student

cd gitosis-admin
vim gitosis.conf

Add:

[group awesome]
writable = denovo
members = admin student

• Commit and push

git add *
git commit -m "Set up a new repository denovo for use by admin and student"
git push

• Create a local working tree for the denovo project:

cd
mkdir denovo
cd denovo
git init
git remote add origin awesome@hpc.ufl.edu:denovo.git

• Add and edit some files
• Commit and push to the Git server

git add *
git commit -m "Initial import"
git push origin master

Output:

Initialized empty Git repository in /git/awesome/repositories/denovo.git/
Counting objects: 3, done.
Writing objects: 100% (3/3), 231 bytes, done.
Total 3 (delta 0), reused 0 (delta 0)
To awesome@git.hpc.ufl.edu:denovo.git
* [new branch]      master -> master

After a new user 'student is allowed access they can start using the repository.

student@linux64

• Clone the denovo repository

git clone awesome@git.hpc.ufl.edu:denovo.git

Output:

Cloning into denovo...

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

• Work in the git working tree

cd denovo

Edit and add files

• Commit and push the changes to the repository

git add *
git commit -m "The changes I made"
git push
