Methods to solve the problem of Java.net.ConnectException:Connection refused of tomcat error __.net

Tomcat Java.net.ConnectException:Connection refused


1, describe
After you configure a new project and modify the Tomcat Server.xml, execute the shutdow.sh script to shut down the server, prompting for the following error:
Tomcat Java.net.ConnectException:Connection refused
A lot of mistakes.

Searching the internet for a lap, a need to restart the server, this is not a bit, but said to be due to 8080 or 8009 ports are occupied caused shutdown failed, but did not resolve

2, solve
Online and have to solve practical problems, to provide my solution to the idea:
We ps-ef|grep Java
Find all Java process numbers
Kill-9 Process Number
Take the process out, except the username xxx xxx 0 20:56 pts/0 00:00:00 grep--color=auto java.


3, reboot
SH start.sh
normal;


4, Reasons and analysis
The reason is that the port is occupied, and so the possibility, it is that you shutdown, Execute the shutdown.sh script, and if the project at this time some database links and so on, so that Tomcat actually did not really shut down, it is not completely shut down, causing you to shutdown again when the error.
