Preface

At work, when I deploy Java code, I usually build a jar locally, scp it to the server, then start it with java -jar. Git isn’t even needed on the server. Recently the project was rewritten in Go. Now there’s an extra requirement on the server: pull the code, compile it, and then start it. Even though I generally write the code locally and only need to pull it on the server, I found that the built-in Git version on CentOS 7 is really old—there aren’t even prompts for the most common branch/status indicators.

Local version 2.30, with branch indicator

Server version 1.8, no branch indicator—looks like a normal folder

yum can’t upgrade

Naturally, I thought about upgrading Git, but after running yum update git I found it was already “the latest version”.

Solution

We just need to specify the repository for this package. Yum’s default repo is probably aiming for stability, but the version is indeed a bit too old. Just add a config under yum’s repo directory.

1. Add a repo file. If you don’t have it, vim will create it automatically in that directory.

vim /etc/yum.repos.d/wandisco-git.repo

1. Add the following content, then :q to save and exit

[ndisco-git]
name=Wandisco GIT Repository
baseurl=http://opensource.wandisco.com/centos/7/git/$basearch/
enabled=1
gpgcheck=1
gpgkey=http://opensource.wandisco.com/RPM-GPG-KEY-WANdisco

1. Import the GPG public key

sudo rpm --import http://opensource.wandisco.com/RPM-GPG-KEY-WANdisco

1. Then run yum update git again

Now take a look—update successful
