Since v2.0 Apache APISIX would not support the v2 protocol storage to etcd anymore, and the minimum etcd version supported is v3.4.0. What's more, etcd v3 uses gRPC as the messaging protocol, while Apache APISIX uses HTTP(S) to communicate with etcd cluster, so be sure the etcd gRPC gateway is enabled.
Now by default Apache APISIX uses HTTP protocol to talk with etcd cluster, which is insecure. Please configure certificate and correspsonding private key for your etcd cluster, and use “https” scheme explicitly in the etcd endpoints list in your Apache APISIX configuration, if you want to keep the data secure and integral. See the etcd section in conf/config-default.yaml for more details.
If you want use Tengine instead of OpenResty, please take a look at this installation step script Install Tengine at Ubuntu.
