HowTo Rally
Installing rally on fresh ubuntu
Install these requirements:
sudo apt-get update sudo apt-get install git-core python-dev libevent-dev libssl-dev sudo pip install virtualenv
Clone rally:
git clone https://github.com/stackforge/rally.git
Install rally requirements in venv:
virtualenv rally/.venv . rally/.venv/bin/activate pip install -r requirements.txt
Setup
Version 0.1
Initial version has many configuration options hardcoded and some things needs to be done manually. Configuration and setup will be improved in future versions.
Currently rally is tested to run on x64 Ubuntu 12.04 server
Install data collector node
Zipkin is used to collect profiling information.
Zipking uses a lot of RAM so collector node should have at least 6 Gb of RAM. Later we may choose alternative collector/visualization solution.
Install with:
$ git clone https://github.com/twitter/zipkin.git
Zipkin uses sqlite by default but it doesn't work under production load. Currently we use Cassandra to store collected data Install Cassandra DB:
$ wget http://mirror.metrocast.net/apache/cassandra/2.0.0/apache-cassandra-2.0.0-bin.tar.gz $ tar xvzf apache-cassandra-2.0.0-bin.tar.gz $ sudo mkdir /var/lib/cassandra $ sudo chmod a+rw /var/lib/cassandra $ sudo mkdir /var/log/cassandra $ sudo chmod a+rw /var/log/cassandra $ apache-cassandra-2.0.0/bin/cassandra &> cassandra-out
Create DB schema for zipkin:
$ apache-cassandra-2.0.0/bin/cassandra-cli -host localhost -port 9160 -f zipkin/zipkin-cassandra/src/schema/cassandra-schema.txt
Zipkin needs 3 services running. For the first time start each one separately and wait for it to load completely so it could download all dependencies
$ bin/collector $ bin/query $ bin/web
Later you can run them all together via screen:
$ screen -dmS zipkin-collector bin/collector cassandra $ screen -dmS zipkin-query bin/query cassandra $ screen -dmS zipkin-web bin/web
Collector node needs to be reachable from all cloud servers and it's IP should be defined in configuration file in deploy section:
'collectors': {
'zipkin': '#data_collector_ip#'
}
