HipChat 4 has recently come out, and then shortly after it was released to my companies internal HipChat server. Being a Linux user I hoped that the aged HipChat 2 client was finally updated for Fedora or Red Hat or CentOS 7 so I could just use yum to install it. When I went to the download page the old yum instructions were replaced by only Ubuntu/Debian instructions! After playing around with the Debian package and getting it to load, I thought I would look at the repo a little more. Low and behold, Atlassian is making a yum repo! Just not publishing instructions on how to use it! The downside is they seem to not be signing the repo, but the code below works with yum to download the latest version.
sudo bash -c ‘cat > /etc/yum.repos.d/hipchat.repo << EOF_hipchat
sudo yum update
sudo yum install hipchat4
