# Configuring command-based system parameters

## Before you begin

The script in this task uses `sudo` access for the user on the Elasticsearch, ASE, ABS, and MongoDB hosts. Ensure the Internet Protocol (IP) *(tooltip: \<div class="paragraph">
\<p>The method by which data is sent across the internet from the source host to the destination host.\</p>
\</div>)* address of these hosts was configured in the `hosts` file. See [Creating a new SSH user and configuring user authentication](pingintelligence_creating_new_ssh_user_configuring_user_authentication.html).

## About this task

To set up system parameters using command-based configuration:

## Steps

1. Run the following command to configure the system parameters on the respective virtual machines (VMs).

   |   |                                                                                                               |
   | - | ------------------------------------------------------------------------------------------------------------- |
   |   | Make sure that the following command is run only when `install_as_sudo` is set to `true` in the `hosts` file. |

   ```
   [pi-api-deployment]# ./bin/start.sh configure
   Please see /opt/pingidentity/pi-api-deployment/logs/ansible.log for
   more details.
   ```

   ### Example:

   An example `ansible.log` file for a successful launch of EC2 instances is shown below:

   ```
   [pi-api-deployment]# tail -f logs/ansible.log
