Stand-alone mode

开启 Stand-alone 模式的 APISIX 节点，将不再使用默认的 etcd 作为配置中心。

这种方式比较适合两类用户：

  1. kubernetes(k8s)：声明式 API 场景，通过全量 yaml 配置来动态更新修改路由规则。
  2. 不同配置中心：配置中心的实现有很多，比如 Consul 等，使用全量 yaml 做中间转换桥梁。

APISIX 节点服务启动后会立刻加载 conf/apisix.yaml 文件中的路由规则到内存，并且每间隔一定时间 （默认 1 秒钟），都会尝试检测文件内容是否有更新，如果有更新则重新加载规则。

注意：重新加载规则并更新时，均是内存热更新，不会有工作进程的替换过程，是个热更新过程。

由于目前 Admin API 都是基于 etcd 配置中心解决方案，当开启 Stand-alone 模式后， Admin API 将不再被允许使用。

通过设置 conf/config.yaml 中的 apisix.config_center 选项为 yaml ，并禁用 Admin API 即可启 用 Stand-alone 模式。

参考下面示例：

  1. apisix:  enable_admin: false  config_center: yaml

如何配置规则

所有的路由规则均存放在 conf/apisix.yaml 这一个文件中，APISIX 会以每秒（默认）频率检查文件是否有变化，如果有变化，则会检查文件末尾是否能找到 #END 结尾，找到后则重新加载文件更新到内存。

下面就是个最小的示例：

  1. routes:  -    uri: /hello    upstream:        nodes:            "127.0.0.1:1980": 1        type: roundrobin#END

注意：如果conf/apisix.yaml末尾不能找到 #END，那么 APISIX 将不会加载这个文件规则到内存。

配置 Router

单个 Router：

  1. routes:  -    uri: /hello    upstream:        nodes:            "127.0.0.1:1980": 1        type: roundrobin#END

多个 Router：

  1. routes:  -    uri: /hello    upstream:        nodes:            "127.0.0.1:1980": 1        type: roundrobin  -    uri: /hello2    upstream:        nodes:            "127.0.0.1:1981": 1        type: roundrobin#END

配置 Router + Service

  1. routes:    -        uri: /hello        service_id: 1services:    -        id: 1        upstream:            nodes:                "127.0.0.1:1980": 1            type: roundrobin#END

配置 Router + Upstream

  1. routes:    -        uri: /hello        upstream_id: 1upstreams:    -        id: 1        nodes:            "127.0.0.1:1980": 1        type: roundrobin#END

配置 Router + Service + Upstream

  1. routes:    -        uri: /hello        service_id: 1services:    -        id: 1        upstream_id: 2upstreams:    -        id: 2        nodes:            "127.0.0.1:1980": 1        type: roundrobin#END

配置 Plugins

  1. # 列出的插件会被热加载并覆盖掉启动时的配置plugins:  - name: ip-restriction  - name: jwt-auth  - name: mqtt-proxy    stream: true # stream 插件需要设置 stream 属性为 true#END

启用 SSL
