+# 1.下载sentinel
+
+https://github.com/alibaba/Sentinel/releases
+
+# 2.使用如下命令启动控制台
+
+```shell
+java -Dserver.port=8858 -Dcsp.sentinel.dashboard.server=localhost:8858 -Dproject.name=sentinel-dashboard -jar sentinel-dashboard.jar
+```
+
+> 注意：sentinel的默认端口为8080，如启动时未修改默认端口则需将app.yml配置文件中的端口修改为8080
+
+```yaml
+csp.sentinel.dashboard.server: localhost:8858
+# 调整为 csp.sentinel.dashboard.server: localhost:8080
+```
+
+>
+其中`-Dserver.port=8858` 用于指定 Sentinel 控制台端口为 8858。默认用户名和密码都是 `sentinel`
+
+# 3.启动当前example
+
+# 4.调用http:localhost:8080
+
+# 5.观察sentinel控制台，发现应用注册到dashboard
