First, you need to download the file using Wget and then install it using RPM on your system to enable the EPEL repository.<\/p>\n

RHEL\/CentOS 7 64 Bit<\/p>\n

\n\n# wget http:\/\/dl.fedoraproject.org\/pub\/epel\/epel-release-latest-7.noarch.rpm\n# rpm -ivh epel-release-latest-7.noarch.rpm\n\n<\/pre>\n
## RHEL\/CentOS 6 64-Bit ##<\/p>\n
\n\n# wget http:\/\/dl.fedoraproject.org\/pub\/epel\/6\/x86_64\/epel-release-6-8.noarch.rpm\n# rpm -ivh epel-release-6-8.noarch.rpm\n\n<\/pre>\n
Check the installation<\/p>\n
\n# yum repolist\n*epel\/x86_64 Extra Packages for Enterprise Linux 7 - x86_64\n<\/pre>\n
Now, install stress<\/p>\n
\n# yum install stress\n<\/pre>\n
To test, first run the uptime command and note down the load average. Next, run the stress command to spawn 8 workers spinning on sqrt() with a timeout of 20 seconds. After running stress, again run the uptime command and compare the load average.<\/p>\n
\n# uptime\n16:39:03 up 1 day, 18:32,  1 user,  load average: 0.15, 0.24, 0.14\n<\/pre>\n
\nsudo stress --cpu  8 --timeout 20\nstress: info: [65429] dispatching hogs: 8 cpu, 0 io, 0 vm, 0 hdd\nstress: info: [65429] successful run completed in 20s\n<\/pre>\n
Now uptime again<\/p>\n
\n# uptime\n 16:40:18 up 1 day, 18:34,  1 user,  load average: 1.35, 0.59, 0.27\n<\/pre>\n
Spawn 8 workers spinning on sqrt() with a timeout of 30 seconds<\/p>\n
