Installing Simulator

Hazelcast Simulator needs a Unix shell to run. Ensure that your local and remote machines are running under Unix, Linux or Mac OS. Hazelcast Simulator may work with Windows using a Unix-like environment such as Cygwin, but that is not officially supported at the moment.

Firewall settings

Please ensure that all remote machines are reachable via TCP ports 22, 9000 and 5701 to 5751 on their external network interface (for example, eth0). The first two ports are used by Hazelcast Simulator. The other ports are used by Hazelcast itself. Port 9001 is used on the loopback device on all remote machines for local communication.

Setup of local machine (Coordinator)

Hazelcast Simulator is provided as a separate downloadable package, in zip or tar.gz format. You can download either one here.

After the download is completed, follow the below steps.

  • Unpack the tar.gz or zip file to a folder that you prefer to be the home folder for Hazelcast Simulator. The file extracts with the name hazelcast-simulator-<version>. (If you are updating Hazelcast Simulator, perform this same unpacking, but skip the following steps.)

  • Add the following lines to the file ~/.bashrc (for Unix/Linux) or to the file ~/.profile (for Mac OS).

export SIMULATOR_HOME=<extracted folder path>/hazelcast-simulator-<version>
  • Create a working folder for your Simulator TestSuite (tests is an example name in the following commands).
mkdir ~/tests
  • Copy the file to your working folder.
cp $SIMULATOR_HOME/conf/ ~/tests

Setup of remote machines (Agents, Workers)

After you have installed Hazelcast Simulator as described in the previous section, make sure you create a user on the remote machines upon which you want to run Agents and Workers. The default username used by Hazelcast Simulator is simulator. You can change this in the file in your working folder.

Please ensure that you can connect to the remote machines with the configured username and without password authentication (see the next section). The Provisioner terminates when it needs to access the remote machines and cannot connect automatically.

Setup of public/private key pair

The preferred method for password free authentication is using an RSA (Rivest,Shamir and Adleman cryptosystem) public/private key pair. The RSA key should not require you to enter the pass-phrase manually. A key with a pass-phrase and ssh-agent-forwarding is strongly recommended, but a key without a pass-phrase also works.

Local machine (Coordinator)

Make sure you have the files and id_rsa in your local ~/.ssh folder.

If you do not have the RSA keys, you can generate a public/private key pair using the following command.

ssh-keygen -t rsa -C ""

Press [Enter] for all questions. The value for the e-mail address is not relevant in this case. After you execute this command, you should have the files and id_rsa in your ~/.ssh folder.

Remote machines (Agents, Workers)

Please ensure you have appended the public key ( to the ~/.ssh/authorized_keys file on all remote machines (Agents and Workers). You can copy the public key to all your remote machines using the following command.

ssh-copy-id -i ~/.ssh/ simulator@remote-ip-address

SSH connection test

You can check if the connection works as expected using the following command from the Coordinator machine (it will print ok if everything is fine).

ssh -o BatchMode=yes simulator@remote-ip-address "echo ok" 2>&1
