Today I will talk about Git. As I suppose you know very well, or at least, you know a little bid of what is it. Git is a code version control software. There are others like SVN, Mercurial… but today I will talk about working with Git locally and deploy your source changes into remote machines. If you need more information about Git, check wikipedia, always useful ;). Link
First of all you have to have Git installed, this guide is quite simple and help you to install GIT in any OS.
Once we have git, we can initialize our first repo.
git add *
git commit -m "First commit with all my initial source"
Here we have the first step, and this could be enough if you’re not going to deploy your code outside your box.
For example, if you have your webserver and you want to deploy your local changes in the source, you may have to do something like this. Other reason could be to have a external backup. If your source is replicated in other box, the possibilities of loosing all your work decreases, everything fails, sooner than you think
In this example I will deploy my changes to my Amazon AWS EC2 machine.
I connect throw SSH to the machine and type this commands:
mkdir -p /var/git/example
git init --bare
Now what we have to do is add a remote repository to our local repo.
We go to your local repo directory and type:
git remote add aws firstname.lastname@example.org:/var/api/example
git push -u aws master
At this point, we have replicated our repo in the cloud ;D easy, isn’t it?
Now what we want to do is to deploy our repo into the working directory, for example the Apache2 directory. In our remote machine, we go to the working directory and type the following:
git clone /var/git/example .
At this time we create a copy of the repo, with master branch prepared to serve your pages!
Now any changes you push to AWS you’ll have to enter in your working directory and pull changes. Easy!
git pull origin master
First post of GIT, more tricks soon!
Stay in the cloud!
