Setting Up Machines Manually

You may want to set up Hazelcast Simulator on the environments different than your clusters placed on a cloud: for example, your local machines, a test laboratory, etc. In this case, perform the following steps.

Copy the SIMULATOR_HOME/conf/simulator.properties to your working directory.
Edit the USER in the simulator.properties file if you want to use a different user name than simulator.
Create an RSA key pair or use an existing one. Using the key should not require entering the pass-phrase manually. A key with pass-phrase and ssh-agent-forwarding is strongly recommended, but a key without a pass-phrase will also work.

You can check whether a key pair exists with this command:
```
ls -al ~/.ssh
```
If it does not exist, you can create a key pair on the client machine with this command:
```
ssh-keygen -t rsa
```
You will get a few more questions:
- Enter a file in which to save the key (/home/demo/.ssh/id_rsa):
- Enter a pass-phrase (empty for no pass-phrase): (pass-phrase is optional)
Copy the public key into the ~/.ssh/authorized_keys file on the remote machines with this command:
```
ssh-copy-id user@123.45.56.78
```
Create the agents.txt file and add the IP addresses of the machines. The content of the agents.txt file with the IP addresses added looks like the following:
```
98.76.65.54
10.28.37.46
```
Run the command provisioner --restart to verify.

NOTE: For the full description of the simulator.properties file, please refer to the Simulator.Properties File Description section.
