Introduction
I use GIT on my local server to track changes for my automation scripts. I also use it to be synced with remote GitHub repositories. Recently, I migrated all my servers to Centos 8 and had to re-configure my Git.
On local server
First, we need to authenticate with a remote repository on GitHub. GitHub uses SSH keys as authentication so we need to create a pair of RSA SSH keys.
ssh-keygen -t rsa -C "pawel@kuligowski.co.uk"
Once created, let’s copy our public key into the GitHub account:
[root@centos ~]# cat /root/.ssh/id_rsa.pub
ssh-rsa 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 pawel@kuligowski.co.uk
Now, log in to your GitHub account, go in to settings and paste the SSH key.
Cloning remote repo to local server
To copy all data from repository, create a directory on a local server and clone the repo.
[root@centos ~]# mkdir /git
[root@centos]# git clone https://github.com/pavbjj/Cisco-Ansible-Playbooks
When cloning remote repo, there’s no need to initilalize this on local server (‘git init’) as ‘git clone’ does it all for you as well as:
git init(create the local repository)git remote add(add the URL to that repository)git fetch(fetch all branches from that URL to your local repository)git checkout(create all the files of the main branch in your working tree)
