The easiest way to install Rally is by executing its installation script
wget -q -O- https://raw.githubusercontent.com/openstack/rally/master/install_rally.sh | bash # or using curl curl https://raw.githubusercontent.com/openstack/rally/master/install_rally.sh | bash
The installation script will also check if all the software required by Rally is already installed in your system; if run as root user and some dependency is missing it will ask you if you want to install the required packages.
By default it will install Rally in a virtualenv in ~/rally when run as standard user, or install system wide when run as root. You can install Rally in a venv by using the option --target:
./install_rally.sh --target /foo/bar
You can also install Rally system wide by running script as root and without --target option:
Run ./install_rally.sh with option --help to have a list of all available options:
$ ./install_rally.sh --help Usage: install_rally.sh [options] This script will install rally either in the system (as root) or in a virtual environment. Options: -h, --help Print this help text -v, --verbose Verbose mode -s, --system Instead of creating a virtualenv, install as system package. -d, --target DIRECTORY Install Rally virtual environment into DIRECTORY. (Default: $HOME/rally). -f, --overwrite Remove target directory if it already exists. -y, --yes Do not ask for confirmation: assume a 'yes' reply to every question. -D, --dbtype TYPE Select the database type. TYPE can be one of 'sqlite', 'mysql', 'postgres'. Default: sqlite --db-user USER Database user to use. Only used when --dbtype is either 'mysql' or 'postgres'. --db-password PASSWORD Password of the database user. Only used when --dbtype is either 'mysql' or 'postgres'. --db-host HOST Database host. Only used when --dbtype is either 'mysql' or 'postgres' --db-name NAME Name of the database. Only used when --dbtype is either 'mysql' or 'postgres' -p, --python EXE The python interpreter to use. Default: /usr/bin/python.
Notes: the script will check if all the software required by Rally is already installed in your system. If this is not the case, it will exit, suggesting you the command to issue as root in order to install the dependencies.
You also have to set up the Rally database after the installation is complete:
rally-manage db recreate
Rally with DevStack all-in-one installation¶
It is also possible to install Rally with DevStack. First, clone the corresponding repositories:
git clone https://git.openstack.org/openstack-dev/devstack git clone https://github.com/openstack/rally
Then, configure DevStack to run Rally. First, create your local.conf file:
cd devstack cp samples/local.conf local.conf
Next, edit local.conf: add enable_plugin rally https://github.com/openstack/rally master to [[local|localrc]] section.
Finally, run DevStack as usually:
Rally & Docker¶
First you need to install Docker; Docker supplies installation instructions for various OSes.
You can either use the official Rally Docker image, or build your own from the Rally source. To do that, change directory to the root directory of the Rally git repository and run:
docker build -t myrally .
If you build your own Docker image, substitute myrally for rallyforge/rally in the commands below.
The Rally Docker image is configured to store local settings and the database in the user’s home directory. For persistence of these data, you may want to keep this directory outside of the container. This may be done by the following steps:
sudo mkdir /var/lib/rally_container sudo chown 65500 /var/lib/rally_container docker run -it -v /var/lib/rally_container:/home/rally rallyforge/rally
In order for the volume to be accessible by the Rally user (uid: 65500) inside the container, it must be accessible by UID 65500 outside the container as well, which is why it is created in /var/lib/rally. Creating it in your home directory is only likely to work if your home directory has excessively open permissions (e.g., 0755), which is not recommended.
All task samples, docs and certification tasks you could find at /opt/rally/. Also you may want to save the last command as an alias:
echo 'alias dock_rally="docker run -it -v /var/lib/rally_container:/home/rally rallyforge/rally"' >> ~/.bashrc
After executing dock_rally, or docker run ..., you will have bash running inside the container with Rally installed. You may do anything with Rally, but you need to create the database first:
user@box:~/rally$ dock_rally rally@1cc98e0b5941:~$ rally-manage db recreate rally@1cc98e0b5941:~$ rally deployment list There are no deployments. To create a new deployment, use: rally deployment create rally@1cc98e0b5941:~$
In case you have SELinux enabled and Rally fails to create the database, try executing the following commands to put SELinux into Permissive Mode on the host machine
sed -i 's/SELINUX=enforcing/SELINUX=permissive/' /etc/selinux/config setenforce permissive
Rally currently has no SELinux policy, which is why it must be run in Permissive mode for certain configurations. If you can help create an SELinux policy for Rally, please contribute!
