seata1.3.0中 can not register RM,err:can not connect to services-server.

• 运行seata测试项目时报错如下：

2020-07-29 14:53:39.075 ERROR 20356 --- [           main] i.s.c.r.netty.NettyClientChannelManager  : 0101 can not connect to 172.19.231.13:8091 cause:can not register RM,err:can not connect to services-server.

io.seata.common.exception.FrameworkException: can not register RM,err:can not connect to services-server.
	at io.seata.core.rpc.netty.NettyClientChannelManager.doConnect(NettyClientChannelManager.java:210) ~[seata-all-1.3.0.jar:1.3.0]

• 追踪NettyClientChannelManager 

• 可是我seata中从来没设置过这个IP呀，最后看了一下服务器的ifconfig，原来是用的内网IP
• 因为我启动seata服务的脚本是用的127.0.0.1

  
  nohup  ./bin/seata-server.sh -p 8091 -h 127.0.0.1 -m file  >log.out 2>1 &

  遂把127.0.0.1改为外网IP，问题解决！
