## 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 Consule 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 实际将不起作用。

## 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
|
|
|
|
|

|
|
|
|
"127.0.0.1:1980": 1
|
|
|
|
|
type: roundrobin
|
|
|
|
|
-
|
|
|
|
|
uri: /hello2
|
|
|
|
|

|
|
|
|
|
nodes:
|
|
|
|
|
"127.0.0.1:1981": 1
|
|
|
|
|
type: roundrobin
|
|
|
|
|
#END
|
|
|
|

```
|
|
