IDEA turns on Tomcat remote debugging

1. Environment

Local: windows7

Server: centos7

Remote tomcat: tomcat8.5

Two, placement

Modify the bin/catalina.sh file and add the following code at the beginning:

export JAVA_OPTS='-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=8000'

Then restart tomcat, centos7 opens port 8000.

Three, IDEA debugging

After the startup is successful, create a new remote debugging in IDEA:

Configure the IP and port, use the IP and that port on the server, as shown in the figure below: 

Four, debugging

Just start it in DEBUG mode in IDEA, just like the local debugging mode.
