Spring Cloud Eureka cluster Dynamic expansion new node

Scenario Description:

Eureka cluster node has two, mutual registration form a cluster, has supported dynamic refresh (do not know how to let Eureka support dynamic refresh can refer to http://www.cnblogs.com/flying607/p/8459397.html), is already running , use Nginx to do load balancing, proxy the cluster, the service's registry address directly write Nginx address.

Now you want to add a Eureka node to this cluster without restarting any services.

The steps to extend the new node are as follows:

0, the new node configuration complete cluster address and start
1, modify the application.yml of each eureka (the configuration file is placed outside the jar package, so it can be easily modified), add new nodes
2. Refresh each Eureka configuration
3, waiting for about 10 minutes (this configuration does not know where to find, I waited for about 10 minutes to see the new node has a movement), refresh the new node, see the Service information synchronization past
4. Modify the Load balancer address of Nginx, add the new node address
5, Nginx-s Reload

Version used:DALSTON.SR1

Off Topic:

The cluster scheme described in this paper has some drawbacks, if a node in the cluster hangs up, there is no perfect fuse and retry measures protection.

If this is a high requirement, consider using lvs+keepalived (listen for a port and remove it in time)

Replace Nginx's agent.

You guys, if there's any good idea, please leave a comment in the comments section.
