No package stress available. How to install stress on CentOS 7.2?

stress is now packaged in the EPEL 7 repository so this should be the preferred way of installation. To enable this repo, you should follow the instructions from the Fedora Wiki and install the epel-release package. Once enabled, you can then install stress. For example:

sudo yum install -y epel-release
sudo yum install -y stress

Stress is not available (yet) in Epel-Repository for RHEL 7. Google will find a RPM you can download from: and install with yum localinstall stress-1.0.2-1.el7.rf.x86_64.rpm.
