sudo pip install pyzmq
Set file limit to unlimited to ensure there is no OS problems with files at concurrency:
ulimit -n 9999

Upload the locust test file (Click here to see how to make a locust testfile)
Exec this command (this only starts the interface to control the tests it doesnt actually start a test):
locust -f ./test.py --host=http://somedomain.io --master
You will get this:
SHOW LOCUST PICS HERE
Go to the web interface to control the test variables and to start and stop it.
Running on multiple hosts:
You will have a master slave setup where only one master exists.
Run the "running a test" steps on each node you want to have as part of the testing cluster but on each slave you should exec this instead:
locust -f ./test.py --host=http://somedomain.io --slave --master-host=x.x.x.x
Where x.x.x.x is the ip of the master you would have set up in the "running a test" section.
You will only need to use the one admin interface provided my the master. It should report whether the slaves are correctly setup and activey serving traffic.
