You can start a node from the command line using the default configuration or by passing a custom configuration file.
16
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:

You will see output similar to this:

61
....
62
[08:53:45] Ignite node started OK (id=7b30bc8e)
63
[08:53:45] Topology snapshot [ver=1, locNode=7b30bc8e, servers=1, clients=0, state=ACTIVE, CPUs=4, offheap=1.6GB, heap=2.0GB]
64
....
65

66
Open another tab from your command shell and run the same command again:
67

68
[tabs]
69
--
70
tab:Unix[]
71
[source,shell]
72
----
73
./ignite.sh ../examples/config/example-ignite.xml
74
----

76
tab:Windows[]

[source,shell]
78
----

84
Check the `Topology snapshot` line in the output.
85
Now you have a cluster of two server nodes with more CPUs and RAM available cluster-wide:
86

87
....
88
[08:54:34] Ignite node started OK (id=3a30b7a4)
89
[08:54:34] Topology snapshot [ver=2, locNode=3a30b7a4, servers=2, clients=0, state=ACTIVE, CPUs=4, offheap=3.2GB, heap=4.0GB]
90
....
91

92

93
NOTE: By default, `ignite.sh|bat` starts a node with the default configuration file: `config/default-config.xml`.
