# application.properties
sentinel.transport.dashboard-address=localhost:8080
sentinel.transport.port=8719 # 可选，默认为8719

# 或者在 application.yml
sentinel:
  transport:
    dashboard-address: localhost:8080
    port: 8719

# 解压下载的文件
unzip sentinel-dashboard-*.zip

# 启动控制台
cd sentinel-dashboard-*
java -jar sentinel-dashboard-*.jar
