Git install latest version on Oracle Linux

 Hey! In this post I would like to discuss about git installation on Oracle Linux. By default git from the yum repo version is older 1.8.2. To get used of the latest features of git needs to install the latest version of git. Currently, the git version is 2.30.1. But this experiment will be same further as well.

Step 1: Navigate to a path where the git installer needs to download.

cd /opt
wget https://mirrors.edge.kernel.org/pub/software/scm/git/git-2.30.1.tar.gz

#remove the default git version from yum repo
yum remove git -y

# extract the git tarball
tar -zxf git-2.30.1.tar.gz
cd git-2.30.1

Step 2: The prerequisites for git installation is as:

# prerequisites
yum install curl-devel expat-devel gettext-devel openssl-devel zlib-devel -y
yum install gcc perl-ExtUtils-MakeMaker -y

Step 3: Install the git version

# installing latest version of git 
make prefix=/usr/local/git all
make prefix=/usr/local/git install

Step 4: Now all set, we need to have the latest git installed directory in the PATH. setting up the PATH for all users on the Machine

# set the global path
echo "export PATH=/usr/local/git/bin:$PATH" >> /etc/bashrc
source /etc/bashrc

git --version

Step 5: After confirmation of the latest version in the PATH. Clean up the installer and extracted folder from /opt directory.

# clean up
cd /opt; rm -rf git-2.30.1 git-2.30.1.tar.gz

Noq id you mix all the above snippets to form an automation script, the name of the script would be "gitinstlal.sh" and the content goes here:

#!/bin/bash
# Install Git latest version on RHEL flavours
# Download this script or use git clone then run regular shell script execution
# ./gitinstall.sh
# Created: 20-Feb-2021
# 

VER=2.30.1
# prerequisites
echo "Install dependencies"
yum install -y wget \
curl-devel expat-devel gettext-devel openssl-devel zlib-devel \
gcc perl-ExtUtils-MakeMaker
cd /opt
wget https://mirrors.edge.kernel.org/pub/software/scm/git/git-${VER}.tar.gz

echo "Check git installed version after dependencies installed..."
git --version
if [ $? -eq 0 ]; 
then
    #remove the default git version from yum repo
    echo "Removal of old version of git"
    yum remove git -y
fi

# extract the git tarball
echo "Extracting git installer"
tar -zxf git-${VER}.tar.gz
cd git-${VER}

# installing latest version of git 
echo "Compile and install git latest version"
make prefix=/usr/local/git all
make prefix=/usr/local/git install

# set the global path
echo "Adding to PATH"
echo "export PATH=/usr/local/git/bin:$PATH" >> /etc/bashrc
source /etc/bashrc
 
git --version | grep ${VER}
[ $? -eq 0 ] && echo "Git installed latest version successfully"

# clean up
echo "Clean up the git installer stuff"
cd /opt; rm -rf git-${VER} git-${VER}.tar.gz
