项目主页：[GitHub - apache/apisix: The Cloud-Native API Gateway](https://github.com/apache/apisix/blob/master/docs/en/latest/how-to-build.md "GitHub - apache/apisix: The Cloud-Native API Gateway")

Apache APISIX 是一个动态、实时、高性能的API网关！基于openrestry+etcd实现，相比于nginx+lua扩展了更多的功能，且易用。可以通过手动添加节点、CONSUL动态发现等方式添加服务节点，方便服务的横向扩容。结合skywalking可以对代理的各个服务进行监控，并且没有入侵性。

# 虚拟机简要部署方式（Centos7 yum）
```
# 安装apisix源并安装apisix和apsix-dashboard
# apisix安装路径/usr/local/apisix/
# dashborad安装路径/usr/local/apisix/dashboard/
$ sudo yum install -y https://repos.apiseven.com/packages/centos/apache-apisix-repo-1.0-1.noarch.rpm
$ sudo yum install -y apisix apisix-dashboard
```

```
# 安装etcd
$ ETCD_VERSION='3.4.13'
$ wget https://github.com/etcd-io/etcd/releases/download/v${ETCD_VERSION}/etcd-v${ETCD_VERSION}-linux-amd64.tar.gz
$ tar -xvf etcd-v${ETCD_VERSION}-linux-amd64.tar.gz && \
    cd etcd-v${ETCD_VERSION}-linux-amd64 && \
    sudo cp -a etcd etcdctl /usr/bin/
$ nohup etcd &
```

```
# 初始化apisix和nginx配置文件
$ apisix init
# 初始化apisix-dashboard配置与服务
$ manager-api install
$ systemctl start apisix && systemctl enable apisix
# 添加你的ip到acl中然后再启动dashboard
$ sed -i '/allow_list:/a\    - ${your_ip}' /usr/local/apisix/dashboard/conf/conf.yaml
$ systemctl start apisix-dashborad && systemctl enable apisix-dashborad
```

* 默认dashboard访问端口：9090
* apisix默认服务端口9080、9443，管理端口：127.0.0.1:9000

TODO:
- [ ] 通过一个apisix-dashboard管理集群化部署的apisix
- [ ] 集群化部署etcd防止单节点带来的数据可用性问题
- [ ] 通过consul动态发现服务
- [ ] 结合skywalking对各个服务的访问情况进行监控
