Balancer module

[taojishou]

Is there no balancer module in version 9.0.x?
how to realize load balancing now

[bryancall]

The plugin is in our 8.1.x tree. We deprecated it because the parent configuration can handle the scenario.

[taojishou]

if use parent configuration , how to set the remap configure?

[taojishou]

We configured the parent cache, now there's a 502 error
remap.config map http://test.ole.com/ http://t.ole.com/
parent.config dest_domain=t.ole.com method=get parent="217.182.197.203:80" round_robin=stric

@rob05c can you help with setting up parent config?

[bryancall]

@taojishou are you still having an issue with this?

[mlibbey]

• can you show a curl to your parent with both the t.ole.com and the test.ole.com host: headers? eg, like
  curl -sIXGET --resolve t.ole.com:80:217.182.197.203 "http://t.ole.com" and
  curl -sIXGET --resolve test.ole.com:80:217.182.197.203 "http://test.ole.com"

For what its worth, the way we use parents is like
Child:
remap:
map http://inbound.example.com http://inbound.example.com
parent.config:
dest_domain= inbound.example.com scheme=http parent="machine.hostname:80" go_direct=false round_robin=consistent_hash
Parent:
remap:
map http://inbound.example.com http://origin.example.com
(and use conf_remap to set/unset proxy.config.url_remap.pristine_host_hdr

The balancer plugin was intentionally removed in Apache Traffic Server 9.0.0 (#5739), because the parent configuration (parent.config) covers the load balancing use case with more features. As noted above, you set up the child with a remap rule plus a parent.config entry pointing at the upstream (using go_direct=false and round_robin such as consistent_hash), and the parent does the origin remap. For the 502 you hit, the usual cause is the parent rule not matching the proxied host, or pristine host header handling, the example earlier in this thread covers the working pattern. Since the original question (no balancer module in 9.0.x, how to load balance now) is answered and there has been no further response, I am closing this. Please open a new issue with a current reproduction if parent.config does not meet your needs.
