Take a look at the figure below. Execute two commands. First find the pid of tomcat, and then find the port according to the pid

It can be seen as follows:

1. Check the process number of tomcat first

ps -ef | grep tomcat*

The * sign is followed to view multiple tomcat, such as tomcat6 and tomcat7.

2. View port number according to process number

netstat -anop | grep 15161

You can see that port numbers 8865, 8866 and 8867 are occupied

3. In addition, you can also view the process number information through the port number

lsof -i: 8866
