-## Admin and Cluster
+```
+{emqtt, [
+   {auth, {anonymous, []}}, %internal, anonymous
+   {listen, [
+       {mqtt, 1883, [
+           {max_conns, 1024},

+```
+
+### etc/vm.args
+
+```
+
+-sname emqtt
+
+-setcookie emqtt
+
+```
+
+When nodes clustered, vm.args should be configured as below:
+
+```
+-name emqtt@host1
+```
 
 ......
 
+## Cluster
+
+Suppose we cluster two nodes on 'host1', 'host2', steps:
+
+on 'host1':
+
+```
+./bin/emqtt start
+```
+
+on 'host2':
+
+```
+./bin/emqtt start
+
+./bin/emqtt_ctl cluster emqtt@host1
+```
+
+Run './bin/emqtt_ctl cluster' on 'host1' or 'host2' to check cluster nodes.
