# 夜间开放端口，挑选流量远程 Debug

## 配置 IntelliJ IDEA 远程 Debug

![debug 配置](http://img.gitnavi.com/tkey/remote-debug-1.png)

* **复制这个 VM 配置**

```
-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=5005
```

## 调整应用启动参数

* 在 应用的原有 JAVA\_OPTS 参数基础上补加，效果如下：

```
JAVA_OPTS="-Xms512m -Xmx2048m -agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=5005"
```

## 启动本地项目

* 然后在项目代码中打断点，跟平时本地 debug 一样
