## 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。
|
||
|
||
通过设置 `conf/config.yaml` 中的 `apisix.config_center` 选项为 `yaml` 表示启
|
||
用 Stand-alone 模式。
|
||
|
||
参考下面示例：
|
||
|
||
```yaml
|
||
apisix:
|
||
# ...
|
||
config_center: yaml # etcd: use etcd to store the config value
|
||
# yaml: fetch the config value from local yaml file `/your_path/conf/apisix.yaml`
|
||
# ...
|
||
```
|
||
|
||
此外由于目前 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。
|
||
|
||
### 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：
|
||
|
||
```yaml
|
||
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：
|
||
|
||
```yaml
|
||
routes:
|
||
-
|
||
uri: /hello
|
||
upstream:
|
||
nodes:
|
||
"127.0.0.1:1980": 1
|
||
type: roundrobin
|
||
#END
|
||
```
|
||
|
||
多个 Router：
|
||
|
||
```yaml
|
||
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
|
||
|
||
```yml
|
||
routes:
|
||
-
|
||
uri: /hello
|
||
service_id: 1
|
||
services:
|
||
-
|
||
id: 1
|
||
upstream:
|
||
nodes:
|
||
"127.0.0.1:1980": 1
|
||
type: roundrobin
|
||
#END
|
||
```
|
||
|
||
### 配置 Router + Upstream
|
||
|
||
```yml
|
||
routes:
|
||
-
|
||
uri: /hello
|
||
upstream_id: 1
|
||
upstreams:
|
||
-
|
||
id: 1
|
||
nodes:
|
||
"127.0.0.1:1980": 1
|
||
type: roundrobin
|
||
#END
|
||
```
|
||
|
||
### 配置 Router + Service + Upstream
|
||
|
||
```yml
|
||
routes:
|
||
-
|
||
uri: /hello
|
||
service_id: 1
|
||
services:
|
||
-
|
||
id: 1
|
||
upstream_id: 2
|
||
upstreams:
|
||
-
|
||
id: 2
|
||
nodes:
|
||
"127.0.0.1:1980": 1
|
||
type: roundrobin
|
||
#END
|
||
```
|
||
|
||
### 配置 Plugins
|
||
|
||
```yml
|
||
# 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
|
||
```
|
||
|
||

||
|
||
```yml
|
||
