同步操作将从 iresty/Apache APISIX 强制同步,此操作会覆盖自 Fork 仓库以来所做的任何修改,且无法恢复!!!
确定后同步将在后台操作,完成时将刷新页面,请耐心等待。
Skywalking is an OpenTracing plugin.
The skywalking server can supports both http and grpc protocols. The APISIX client only support http protocols.
Name | Type | Requirement | Default | Valid | Description |
---|---|---|---|---|---|
sample_ratio | number | required | 1 | [0.00001, 1] | the ratio of sample |
First of all, enable the skyWalking plugin in the config.yaml
:
# Add this in config.yaml
plugins:
- ... # plugin you need
- skywalking
Then reload APISIX, a background timer will be created to report data to skywalking server.
Here's an example, enable the skywalking plugin on the specified route:
curl http://127.0.0.1:9080/apisix/admin/routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
{
"methods": ["GET"],
"uris": [
"/uid/*"
],
"plugins": {
"skywalking": {
"sample_ratio": 1
}
},
"upstream": {
"type": "roundrobin",
"nodes": {
"10.110.149.175:8089": 1
}
}
}'
You can open dashboard with a browser:http://127.0.0.1:9080/apisix/dashboard/
,to complete the above operation through the web interface, first add a route:
Then add skywalking plugin:
We can set the endpoint by specified the configuration in conf/config.yaml
.
Name | Type | Default | Description |
---|---|---|---|
service_name | string | "APISIX" | service name for skywalking reporter |
service_instance_name | string | "APISIX Instance Name" | service instance name for skywalking reporter |
endpoint | string | "http://127.0.0.1:12800" | the http endpoint of Skywalking, for example: http://127.0.0.1:12800 |
Here is an example:
plugin_attr:
skywalking:
service_name: APISIX
service_instance_name: "APISIX Instance Name"
endpoint_addr: http://127.0.0.1:12800
Run Skywalking Server:
By default, use H2 storage, start skywalking directly
sudo docker run --name skywalking -d -p 1234:1234 -p 11800:11800 -p 12800:12800 --restart always apache/skywalking-oap-server
Of Course, you can use Elasticsearch storage
Firstly, you should install Elasticsearch:
sudo docker run -d --name elasticsearch -p 9200:9200 -p 9300:9300 --restart always -e "discovery.type=single-node" elasticsearch:6.7.2
You can install ElasticSearch management page: elasticsearch-hq(Optional)
sudo docker run -d --name elastic-hq -p 5000:5000 --restart always elastichq/elasticsearch-hq
Run skywalking server:
sudo docker run --name skywalking -d -p 1234:1234 -p 11800:11800 -p 12800:12800 --restart always --link elasticsearch:elasticsearch -e SW_STORAGE=elasticsearch -e SW_STORAGE_ES_CLUSTER_NODES=elasticsearch:9200 apache/skywalking-oap-server
Skywalking WebUI:
Run SkyWalking webUI Server:
sudo docker run --name skywalking-ui -d -p 8080:8080 --link skywalking:skywalking -e SW_OAP_ADDRESS=skywalking:12800 --restart always apache/skywalking-ui
Open the webUI of skywalking: You can open dashboard with a browser: http://10.110.149.175:8080. It will be a successful install as follow:
Test:
Access to upstream services through access apisix:
$ curl -v http://10.110.149.192:9080/uid/12
HTTP/1.1 200 OK
OK
...
Open the webUI of skyWalking:
http://10.110.149.175:8080/
You can see the topology of all service
You can also see the tracer of all service
When you want to disable the skyWalking plugin on a route/service, it is very simple, you can delete the corresponding json configuration in the plugin configuration, no need to restart the service, it will take effect immediately:
$ curl http://127.0.0.1:2379/v2/keys/apisix/routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d value='
{
"methods": ["GET"],
"uris": [
"/uid/*"
],
"plugins": {
},
"upstream": {
"type": "roundrobin",
"nodes": {
"10.110.149.175:8089": 1
}
}
}'
The skywalking plugin has been disabled now. It works for other plugins.
If you want to disable skywalking plugin totally, for example, stop the background report timer,
you need to comment out in the config.yaml
:
plugins:
- ... # plugin you need
#- skywalking
And then reload APISIX.
package com.lenovo.ai.controller;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import javax.servlet.http.HttpServletRequest;
/**
* @author cyxinda
* @create 2020-05-29 14:02
* @desc skywalking test controller
**/
@RestController
public class TestController {
@RequestMapping("/uid/{count}")
public String getUidList(@PathVariable("count") String countStr, HttpServletRequest request) {
System.out.println("counter:::::-----"+countStr);
return "OK";
}
}
Configuring the skywalking agent, when starting the service. update the file of agent/config/agent.config
agent.service_name=yourservername
collector.backend_service=10.110.149.175:11800
Run the script:
nohup java -javaagent:/root/skywalking/app/agent/skywalking-agent.jar \
-jar /root/skywalking/app/app.jar \
--server.port=8089 \
2>&1 > /root/skywalking/app/logs/nohup.log &
