一.服务端配置:jvm

1 2	Jdk1.7之前: -Xdebug -Xrunjdwp:server=y,transport=dt_socket,address=8000,suspend=n jdk1.7之后: -agentlib:jdwp=transport=dt_socket,address=8000,server=y,suspend=n

二.客户端连接:idea远程调试配置及注意

server处port非远程端口,填错后果严重
Startup/Connection,Debug Trasport-Socket - Port为远程调试端口

三.端口查看与释放

确定进程(找到端口address=9996)

1	[admin@10-57-19-191 ~]$ ps -ef \|grep 20974

查看连接发起方

1 2	[admin@10-57-19-191 ~]$ netstat -an\|grep 9996 tcp 0 0 10.57.19.191:9996 10.57.240.227:56516 ESTABLISHED 20974/java
