# 一、引言 #

最近自己负责的项目上线了，部署到测试环境的时候就碰到了bug。为了定位问题，就需要使用到远程调试的。idea的远程调试tomcat功能非常给力，就和本地debug一样，很实用和方便，所以分享出来方便大家定位bug。

# 二、实现方法 #

> 1.  给tomcat添加远程debug支持

在catalina.sh文件首行添加`CATALINA_OPTS="-Xdebug -Xrunjdwp:transport=dt_socket,address=5005,server=y,suspend=n"`,注意address可以自定义

> 1.  重新启动tomcat

进入到bin目录下，先关闭服务`./shutdown.sh`,重新启动服务`./startup.sh`

> 1.  idea配置

1.  点击编辑启动配置

4.  点击debug启动

    如果出现虚拟机参数，代表启动成功，接下来就开始debug吧
