注意
====
- Apache APISIX 从 v2.0 开始不再支持 `v2` 版本的 etcd，并且 etcd 最低支持版本为 v3.4.0，因此请使用 etcd 3.4.0+。更重要的是，因为 etcd v3 使用 gPRC 作为消息传递协议，而 Apache APISIX 使用 HTTP(S) 与 etcd 集群通信，因此请确保启用 [etcd gRPC gateway](https://etcd.io/docs/v3.4.0/dev-guide/api_grpc_gateway/) 功能。

- 目前 Apache APISIX 默认使用 HTTP 协议与 etcd 集群通信，这并不安全，如果希望保障数据的安全性和完整性。 请为您的 etcd 集群配置证书及对应私钥，并在您的 Apache APISIX etcd endpoints 配置列表中明确使用 `https` 协议前缀。请查阅 `conf/config-default.yaml` 中 etcd 一节相关的配置来了解更多细节。

- 如果你要想使用 Tengine 替代 OpenResty，请参考 [Install Tengine at Ubuntu](../../.travis/linux_tengine_runner.sh)。
