Hostname Binding

Lookup order

Default host IP lookup order：

• Get local address via LocalHost.getLocalHost().
• If it is 127. * loopback address, then scan the network for host IP

Host configuration

Registered address if it is not correct, such as the need to register public address, you can do this:

1. edit /etc/hosts : add machinename and public ip, such as:

   test1 205.182.23.201
   

2. in dubbo.xml add host address configuration:

   <dubbo:protocol host="205.182.23.201">
   

3. or config that in dubbo.properties:

   properties dubbo.protocol.host=205.182.23.201
