## Test Plugin
### Run-Skywalking-Example
#### e.g.
+
1. Run Skywalking Server:
- - By default,use H2 storage , start skywalking directly
- ```
+ - By default, use H2 storage, start skywalking directly
+
+ ```shell
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
- 1. Firstly, you should install elasticsearch:
