How To Install Git Using Yum

As is the case with most Linux distributions, git is available from CentOS's default repositories. We can install the package maintainer's most recent version with:

sudo yum install git


How To Set Up Git

When you commit changes with git, it embeds your name and email address into the commit message in order to easily track changes.

If we do not configure this information ourselves, git may try to guess these values (probably incorrectly) by using your Linux username and hostname.

Give git the values you wish to use for these parameters with these commands:

git config --global user.name "Your Name Here"
git config --global user.email "your_email@example.com"

The configuration changes will be stored in a file in your home directory. You can see them with a normal text editor:

nano ~/.gitconfig

[user]
        name = Your Name Here
        email = your_email@example.com

You can also view this information by querying git itself for the current configuration settings:

git config --list

user.name=Your Name Here
user.email=your_email@example.com

As mentioned earlier, if you forget to set up these steps, git may try to fill in these values automatically:

[master 0d9d21d] initial project version
 Committer: root
Your name and email address were configured automatically based
on your username and hostname. Please check that they are accurate.
You can suppress this message by setting them explicitly:

    git config --global user.name "Your Name"
    git config --global user.email you@example.com

After doing this, you may fix the identity used for this commit with:

    git commit --amend --reset-author

Depending on your version of git, it may fail entirely:

git commit

*** Please tell me who you are.

Run

  git config --global user.email "you@example.com"
  git config --global user.name "Your Name"

to set your account's default identity.
Omit --global to set the identity only in this repository.

fatal: empty ident name (for ) not allowed

As you can see, git is very good about telling you exactly what you should be doing.
