RadarGun ships with a number of scripts to help you deploy the framework across a cluster of nodes. The scripts currently require:
- UNIX or UNIX-like environment to run
- Tested on Fedora and RHEL Linux
- SSH with passphraseless keys installed such that the master node can connect to slaves transparently
- Java, Maven and git installed and on the user's path on all of the nodes
- the scripts that start master/slaves must be run from the distribution directory (i.e. one level up from
bin). This is because the resulting processes will look up classed from
plugindirectory, and they depend on the relative location of it.
- for all the scripts, when run
-hargument will print a help message.
Designed to be run on each slave, to start up the local slave process. Slaves need to be aware of the IP[:port] of the master. Master must be running before starting a slave.
Designed to be run on the master node, in order to start the master. Default config used is
Used for running local benchmarks. Default config used is
Starts the master and then it starts all the slaves. For starting the master it relies on
master.sh, for slaves it relies on
slave.sh. In order to be able to start the slaves, it ssh on slaves's machine and runs
slave.sh there. Addresses of slaves can be specified in
Using the dist.sh script on a single machine (Fedora 22)
Create virtual interfaces (eth0 is some physical interface)
sudo ifconfig eth0:1 192.168.11.101 netmask 255.255.255.0 sudo ifconfig eth0:2 192.168.11.102 netmask 255.255.255.0 sudo ifconfig eth0:3 192.168.11.103 netmask 255.255.255.0
Make sshd listen on the new interfaces - add the following to /etc/ssh/sshd_config
ListenAddress 192.168.11.101 ListenAddress 192.168.11.102 ListenAddress 192.168.11.103
Create aliases - add the following to /etc/hosts
192.168.11.101 test1 192.168.11.102 test2 192.168.11.103 test3
sudo systemctl restart network sudo systemctl restart sshd
If you don't have a passwordless ssh key, you will need to create one. Make sure you set an output file other than ~/.ssh/id_rsa, so as not to override your old key. Other than that, just hit enter.
ssh-keygen -t rsa
ssh -i --path to the passwordless key-- test1 echo "Interfaces set up"
Finally, run Radargun with the dist.sh script
sh bin/dist.sh test1 test2 test3
Used by other scripts to set environment variables (JVM options, binding addresses of slaves , etc.).
This script helps detect slave IPs if slaves are assigned IPs using DHCP and no proper domain is set. Assumes that the script is run on the master node, and the master node runs the DHCP server which the slaves use to obtain IPs. Slave names are added to
/etc/hosts so that slaves can easily be reached after running this script. This script shall be run manually, i.e. it is not called implicitly by
Useful when slaves are reprovisioned each time, e.g., using PXE boot and kickstart. This adds each slave's SSH keys/fingerprints to the local user's SSH
known_hosts file so that the user isn't prompted to accept the fingerprint the first time an SSH connection is made.
