|
下面是一个示例，在指定的 route 上开启了 zipkin 插件:
|
|
|
|
|
|
|
|
|
|
|
|
```shell
|
2020-03-05 14:48:27 +08:00
|
|
|
|
curl http://127.0.0.1:9080/apisix/admin/routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '

2019-09-23 06:13:06 +08:00
|
|
|
|
{
|
|
|
|
|
|
"methods": ["GET"],
|
|
|
|
|
|
"uri": "/index.html",
|
|
|
|
|
|
"plugins": {
|
|
|
|
|
|
"zipkin": {
|
|
|
|
|
|
"endpoint": "http://127.0.0.1:9411/api/v2/spans",
|
|
|
|
|
|
"sample_ratio": 1
|
|
|
|
|
|
}
|
|
|
|
|
|
},
|
|
|
|
|
|
"upstream": {
|
|
|
|
|
|
"type": "roundrobin",
|
|
|
|
|
|
"nodes": {
|
|
|
|
|
|
"39.97.63.215:80": 1
|
|
|
|
|
|
}
|
|
|
|
|
|
}
|
|
|
|
|
|
}'
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
你可以使用浏览器打开 dashboard：`http://127.0.0.1:9080/apisix/dashboard/`，通过 web 界面来完成上面的操作，先增加一个 route：
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
然后在 route 页面中添加 zipkin 插件：
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
## 测试插件
|
|
|
|
|
|
|
|
|
|
|
|
### 运行 Zipkin 实例
|
|
|
|
|
|
|
|
|
|
|
|
e.g. 用docker:
|
|
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
|
sudo docker run -d -p 9411:9411 openzipkin/zipkin
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
测试示例:
|
|
|
|
|
|
|
|
|
|
|
|
```shell
|
|
|
|
|
|
$ curl http://127.0.0.1:9080/index.html
|
|
|
|
|
|
HTTP/1.1 200 OK
|
|
|
|
|
|
...
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
打开浏览器，访问 Zipkin 的 web 页面：
|
|
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
|
http://127.0.0.1:9411/zipkin
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
## 禁用插件
|
|
|
|
|
|
|
|
|
|
|
|
当你想去掉插件的时候，很简单，在插件的配置中把对应的 json 配置删除即可，无须重启服务，即刻生效：
|
|
|
|
|
|
|
|
|
|
|
|
```shell
|
|
|
|
|
|
$ curl http://127.0.0.1:2379/v2/keys/apisix/routes/1 -X PUT -d value='
|
|
|
|
|
|
{
|
|
|
|
|
|
"methods": ["GET"],
|
|
|
|
|
|
"uri": "/index.html",
|
|
|
|
|
|
"plugins": {
|
|
|
|
|
|
},
|
|
|
|
|
|
"upstream": {
|
|
|
|
|
|
"type": "roundrobin",
|
|
|
|
|
|
"nodes": {
|
|
|
|
|
|
"39.97.63.215:80": 1
|
|
|
|
|
|
}
|
|
|
|
|
|
}
|
|
|
|
|
|
}'
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
现在就已经移除了 Zipkin 插件了。其他插件的开启和移除也是同样的方法。
