注意
====
- Apache APISIX 目前只支持 `v2` 版本的 etcd，但是最新版的 etcd (从 3.4 起)已经默认关闭了 `v2` 版本的功能。所以你需要添加启动参数 `--enable-v2=true` 来开启 `v2` 的功能，目前对 `v3` etcd 的开发工作已经启动，不久后便可投入使用。

```shell
etcd --enable-v2=true &
```

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