To install Cassandra as a service, you must install and configure the appropriate startup script for your system. For example, see the following example startup scripts:
You must have root or sudo permissions to start Cassandra as a service. For example, typically the command to start Cassandra as a service is as follows:

Run the following command:
sudo kill *pid*
Stop Cassandra as a service
You must have

Connect to API Gateway for the first time
Connecting to API Gateway depends on your operating system and installation setup type (Standard, Complete, or Custom).
Standard or Complete setup
If you installed a default Standard or Complete setup (both include the QuickStart tutorial), Cassandra is installed on the same host, and listens on
localhost by default. API Gateway runs on the same host and connects to Cassandra by default.
If you installed a Custom setup and did not select the Quickstart tutorial, you must update the API Gateway Cassandra client configuration as follows:
- Open the API Gateway group configuration in Policy Studio.
- Select Server Settings > Cassandra > Authentication, and set the Cassandra username/password (default is
- Select Server Settings > Cassandra > Hosts. Add an address for the Cassandra node. You can enter an IP address or host name.
- Deploy the configuration to the API Gateway group.
For more details on configuring Server Settings in the Policy Studio client, see Cassandra Settings.
For details on updating the Cassandra server configuration, see Configure a highly available Cassandra cluster.
