+# 作用
+这个role的作用是部署nano集群。
+
+nano 分为 core, cell, frontend 三个组件。
+
+* core 是主控端。
+* cell 是被控端。
+* frontend 是前端进程。
+
+这里可以为host指定 `nano_role` 的变量来决定其部署为哪种角色。(还没有实现)
+目前主要是部署cell.
+
+## examples
+
+```yaml
+# group_vars/nano_cell.yml
+
+## nano core 的实际ip地址
+nano_core_ph_ip: 10.111.32.182
+## nano core 的vxlan ip
+nano_core_vxlan_ip: 172.16.5.182
+## nano 通信时的组播地址
+nano_multicast_address: 224.0.0.226
