You can start a node from the command line using the default configuration or by passing a custom configuration file.
You can start as many nodes as you like and they will all automatically discover each other.

Navigate into the `bin` folder of the Ignite installation directory from the command shell.
Your command might look like this:

[tabs]
--

tab:Unix[]
[source,shell]
----
cd {IGNITE_HOME}/bin/
----

tab:Windows[]
[source,shell]
----
cd {IGNITE_HOME}\bin\
----

--


Start a node with a custom configuration file that is passed as a parameter to `ignite.sh|bat` like this:


[tabs]
--

tab:Unix[]
[source,shell]
----
./ignite.sh ../examples/config/example-ignite.xml
----

tab:Windows[]
[source,shell]
----
ignite.bat ..\examples\config\example-ignite.xml
----
--


You will see output similar to this:

....
[08:53:45] Ignite node started OK (id=7b30bc8e)
[08:53:45] Topology snapshot [ver=1, locNode=7b30bc8e, servers=1, clients=0, state=ACTIVE, CPUs=4, offheap=1.6GB, heap=2.0GB]
....

Open another tab from your command shell and run the same command again:

[tabs]
--
tab:Unix[]
[source,shell]
----
./ignite.sh ../examples/config/example-ignite.xml
----

tab:Windows[]
[source,shell]
----
ignite.bat ..\examples\config\example-ignite.xml
----

--

Check the `Topology snapshot` line in the output.
Now you have a cluster of two server nodes with more CPUs and RAM available cluster-wide:

....
[08:54:34] Ignite node started OK (id=3a30b7a4)
[08:54:34] Topology snapshot [ver=2, locNode=3a30b7a4, servers=2, clients=0, state=ACTIVE, CPUs=4, offheap=3.2GB, heap=4.0GB]
....


NOTE: By default, `ignite.sh|bat` starts a node with the default configuration file: `config/default-config.xml`.
