This article will show you how to install and configure Git on your local Linux computer (CentOS in this example) or a remote Dev server, and then clone a working copy of your existing project to Bitbucket. I assume you already created an account and a Git repo with Bitbucket. If not just follow this instruction and then come back to this page.
Installing Git
To install Git under CentOS:
# yum install git-core |
The global configuration file ‘.gitconfig‘ is located in the user’s home directory. All global settings are stored in this file.
The --global option need to be used for global configuration, otherwise your configuration is specific for the current Git repository.
If you want to configure Git system wide (for every user and repository on the system), use the --system option. All system configuration settings are stored in /etc/gitconfig file.
Basic configuration
Let’s configure the basic stuff like username, email and the default editor.
# git config --global user.name "FirstNam LastName" # git config --global user.email "Email_Address" # git config --global core.editor vim |
You can list the existing global settings with the following command:
# git config --list |
For more settings check out this page: git-config manual page
How to ignore certain files
If you want to ignore certain files, you need to create a file called ‘.gitignore‘ with the name of the files and/or directories that you want to exclude. This file can be anywhere (user’s home directory for example).
# touch ~/.gitignore # echo "whatever_filename" >> .gitignore # echo "whatever_directory" >> .gitignore |
To ignore all files that end with ‘.jpg‘ and ‘.bak‘:
# echo "*jpg" >> .gitignore # echo "*bak" >> .gitignore |
Now configure Git to use this file as global .gitignore:
# git config --global core.excludesfile ~/.gitignore |
Clone a working project
Let’s say you have a working copy of your project under /var/www/repos/project1 on your local system or Dev box, and you want to put the source code under version control.
1. Change to the working directory:
# cd /var/www/repos/project1 |
2. Create git repository:
# git init |
3. Connect your repository:
# git remote add origin ssh://[email protected]/your_username/your_repo.git |
Where:
your_username – is your Bitbucket’s username.
your_repo – is the new repository you created with Bitbucket.
4. Add and commit your source files:
# git add . # git commit -m "Initial commit" |
5. Push all changes:
# git push -u origin master |
To check the log:
# git log |
To check the status:
# git status |
Removing files
If you want to remove a file. Use following commands:
# git rm test.txt # git commit -m "Removed test.txt" # git push origin |
Editing files and pushing changes
# echo "Some code changes" >> test.txt # git commit -m "Some code changes to test.txt" # git push origin |
Clone a repository to local system
If someone is working with you on the same project. He/she can clone the project like so:
git clone [email protected]:your_username/your_repo.git |
