Starting and Shutting Down Nodes

This chapter explains how to start server nodes and client nodes. Refer to the Installation Guide for the installation instructions.

You can start a node by running the ignite.sh script.

Starting Server Nodes

To start a regular server node, use the following command or code snippet:

ignite.sh path/to/configuration.xml

IgniteConfiguration cfg = new IgniteConfiguration();
Ignite ignite = Ignition.start(cfg);

The Ignite is an autoclosable resource. You can use the try-with-resouce statement to automatically close it:

IgniteConfiguration cfg = new IgniteConfiguration();

try (Ignite ignite = Ignition.start(cfg)) {
    //
}

Starting Client Nodes

To start a client node, simply enable the client mode in the node’s configuration:

<bean class="org.apache.ignite.configuration.IgniteConfiguration" id="ignite.cfg">
    <property name="clientMode" value="true"/>
    <!-- other properties -->
</bean>

IgniteConfiguration cfg = new IgniteConfiguration();

// Enable client mode.
cfg.setClientMode(true);

// Start a client
Ignite ignite = Ignition.start(cfg);

Shutting Down Nodes

If you started a node by running the ignite.sh script and didn’t detach from the terminal, you can stop the node by higgint Ctrl+C. If you detached from the terminal, you can kill the node by executing the kill command:

kill -d <pid>

To stop a node from the program that launched it, use the following code:

ignite.close();

Ignition::Stop(ignite.GetName(), false);
