dist_auto_connect的作用

轉載：http://mryufeng.iteye.com/blog/343202

Normally, connections are established automatically when another node is referenced（也就是說給節點發資訊 ping rpc等等）. This functionality can be disabled by setting the Kernel configuration parameter
dist_auto_connect to false, see kernel(6). In this case, connections must be established explicitly by calling net_kernel:connect_node/1.

這個參數保證了只是你想explictly串連的節點才在你的nodes()列表裡面.因為不需要的節點需要維護 發tick包什麼的 浪費資源！

節點間如何established automatically請參考另外一篇
