How to send a REST request to another node if the service on the current node is not available?

[musicdenotation]

Hi, All,

We setup a cluster of three nodes and running ngix on each node to load
balance.

I found that if a REST service is unavailable on current node, the
corresponding REST request sending to this node
will return the service unavailable response to the client. Is there a
way (e.g. configuration parameter) to let ngix service running in this
node
to redirect the REST request to another node automatically in this case?

Thanks

Depending on your configuration, you may consider using one or
more of the following mechanisms:

• error_page, see Module ngx_http_core_module
• proxy_next_upstream, see Module ngx_http_proxy_module
• backup servers in an upstream blocks, see
  Module ngx_http_upstream_module
