什么是 APISIX?

APISIX 是一个云原生、高性能、可扩展的微服务 API 网关。

它是基于 OpenResty 和 etcd 来实现,和传统 API 网关相比,APISIX 具备动态路由和插件热加载,特别适合微服务体系下的 API 管理。

为什么选择 APISIX?

如果你正在构建网站、移动设备或 IoT(物联网)的应用,那么你可能需要使用 API 网关来处理接口流量。

APISIX 是基于云原生的微服务 API 网关,可以处理传统的南北向流量,也可以处理服务间的东西向流量。

APISIX 通过插件机制,提供动态负载平衡、身份验证、限流限速等功能,并且支持你自己开发的插件。

更多详细的信息,可以查阅 APISIX 的白皮书

功能

  • 云原生: 平台无关,没有供应商锁定,无论裸机还是 Kubernetes,APISIX 都可以运行。
  • 热更新和热插件: 无需重启服务,就可以持续更新配置和插件。
  • 动态负载均衡:动态支持有权重的 round-robin 负载平衡。
  • 支持一致性 hash 的负载均衡:动态支持一致性 hash 的负载均衡。
  • SSL:动态加载 SSL 证书。
  • 反向代理
  • 健康检查:启用上游节点的健康检查,将在负载均衡期间自动过滤不健康的节点,以确保系统稳定性。
  • 熔断器: 智能跟踪不健康上游服务.
  • 身份认证: key-auth, JWT
  • 限制速率
  • 限制请求数
  • 限制并发
  • OpenTracing: Zipkin
  • 监控和指标: Prometheus
  • gRPC 协议转换:支持协议的转换,这样客户端可以通过 HTTP/JSON 来访问你的 gRPC API。
  • Serverless: 在 APISIX 的每一个阶段,你都可以添加并调用自己编写的函数。
  • 自定义插件: 允许挂载常见阶段,例如rewriteaccessheader filerbody filterlog,还允许挂载 balancer 阶段。
  • 控制台: 内置控制台来操作 APISIX 集群。
  • 版本控制:支持操作的多次回滚。
  • CLI: 使用命令行来启动、关闭和重启 APISIX。
  • REST API
  • Proxy Websocket
  • IPv6:支持使用 IPv6 格式匹配路由。
  • 集群:APISIX 节点是无状态的,创建配置中心集群请参考 etcd Clustering Guide
  • 可扩展:简单易用的插件机制方便扩展。
  • 高性能:在单核上 QPS 可以达到 24k,同时延迟只有 0.6 毫秒。
  • 防御 ReDoS(正则表达式拒绝服务)
  • IP 黑名单
  • OAuth2.0: TODO。
  • ACL: TODO。
  • Bot detection: TODO。

在线演示版本

我们部署了一个在线的 dashboard ,方便您了解 APISIX。

安装

APISIX 在以下操作系统中做过安装和运行测试:

操作系统 OpenResty 状态
CentOS 7 1.15.8.1
Ubuntu 16.04 1.15.8.1
Ubuntu 18.04 1.15.8.1
Debian 9 1.15.8.1
Mac OSX 1.15.8.1

现在有两种方式来安装: 如果你是 CentOS 7 的系统,推荐使用 RPM 包安装;其他的系统推荐使用 Luarocks 安装。

通过 RPM 包安装(CentOS 7)

sudo yum install yum-utils
sudo yum-config-manager --add-repo https://openresty.org/package/centos/openresty.repo
sudo yum install -y openresty etcd
sudo service etcd start

sudo yum install -y https://github.com/iresty/apisix/releases/download/v0.6/apisix-0.6-0.el7.noarch.rpm

如果安装成功,就可以参考 快速上手 来进行体验。如果失败,欢迎反馈给我们。

通过 Luarocks 安装

依赖项

APISIX 是基于 openresty 之上构建的, 配置数据的存储和分发是通过 etcd 来完成。

我们推荐你使用 luarocks 来安装 APISIX,不同的操作系统发行版本有不同的依赖和安装步骤,具体可以参考: 安装前的依赖

安装 APISIX

sudo luarocks install --lua-dir=/usr/local/openresty/luajit apisix

如果你得到 unknow flag --lua-dir 这类错误,这是因为 luarocks 版本过低。这时我们需要移除 lua-dir 选项重新运行:luarocks install apisix

如果一切顺利,你会在最后看到这样的信息:

apisix is now built and installed in /usr (license: Apache License 2.0)

恭喜你,APISIX 已经安装成功了。

开发环境

如果你是一个开发者,可以从 开发文档 中获取搭建开发环境和运行测试案例的步骤.

快速上手

  1. 启动 APISIX
sudo apisix start
  1. 测试限流插件

你可以测试限流插件,来上手体验 APISIX,按照限流插件文档的步骤即可.

更进一步,你可以跟着文档来尝试更多的插件.

控制台

APISIX 内置了 dashboard,使用浏览器打开 http://127.0.0.1:9080/apisix/dashboard 即可使用, 不用填写用户名和密码,直接登录。

dashboard 默认只放行了 127.0.0.0/24 的本地 IP,其他地址禁止访问。 你可以自行修改 conf/config.yaml 中的 allow_admin 字段,来增加更多可以访问 dashboard 的 IP。

性能测试

使用谷歌云的 4 核心服务器来运行 APISIX,QPS 可以达到 60000,同时延时只有 0.5 毫秒。

你可以看出性能测试文档来了解更多详细内容。
