Rally setup

The simplest way to start using Rally is to install it together with OpenStack using DevStack. If you already have an existing OpenStack installation and/or don't want to install DevStack, then the preferable way to set up Rally would be to install it manually. Both types of installation are described below in full detail.

Rally with DevStack all in one installation

To install Rally with DevStack, you should first clone the corresponding repositories and copy the files necessary to integrate Rally with DevStack:

 git clone https://github.com/openstack-dev/devstack
 git clone https://github.com/stackforge/rally
 cp rally/contrib/devstack/lib/rally devstack/lib/
 cp rally/contrib/extras.d/70-rally.sh devstack/extras.d/

To configure DevStack to run Rally:

 cd devstack
 echo "enable_service rally" >> localrc

Finally, run DevStack as usually:

 ./stack.sh

And finally you are able to use it!

Manual installation

Prerequisites

Start with installing some requirements that Rally needs to be set up correctly. The specific requirements depend on the environment you are going to install Rally in:

Ubuntu

 sudo apt-get update
 sudo apt-get install libpq-dev git-core python-dev libevent-dev libssl-dev python-pip
 sudo pip install pbr

CentOS

 sudo yum install gcc git-core postgresql-libs python-devel libevent-devel openssl-devel
 #install pip on centos:
 curl -o /tmp/ez_setup.py https://sources.rhodecode.com/setuptools/raw/bootstrap/ez_setup.py 
 sudo /usr/bin/python /tmp/ez_setup.py 
 sudo /usr/bin/easy_install pip 
 sudo rm setuptools-*.tar.gz 
 sudo pip install -i https://pypi.rhodecode.com/ --upgrade pip
 sudo pip install pbr

VirtualEnv

Another option is to install Rally in virtualenv; you should then install this package, create a virtualenv and activate it:

 sudo pip install -U virtualenv
 virtualenv .venv
 . .venv/bin/activate  # NOTE: Make sure that your current shell is either bash or zsh (otherwise it will fail)
 sudo pip install pbr

Installing Rally

The next step is to clone & install rally:

 git clone https://github.com/stackforge/rally.git && cd rally
 python setup.py install

Now you are ready to configure Rally (in oder for it to be able to use the database):

 sudo mkdir /etc/rally 
 sudo cp etc/rally/rally.conf.sample /etc/rally/rally.conf
 sudo vim /etc/rally/rally.conf
 # Change the "connection" parameter, 
 # e.g. to connection="sqlite://///home/<your_username>/.venv/rally-db/$sqlite_db" (or any other place)

After the installation step has been completed, you need to create the Rally database:

 rally-manage db recreate

And finally you are able to use it!

Running Rally's Unit Tests

Rally should be tested with tox, but is not compatible with the current version of tox, so install tox 1.6.1 then run it.

 pip install 'tox<=1.6.1'
 tox
