tomcat停止失败 java.net.ConnectException: Connection refused
今天遇到个很郁闷的问题，使用catalina.sh stop 或者 shutdown.sh 关闭tomcat总是失败，总提示连接超时。开始以为是自己tomcat配置的问题，重新部署上没更改过配置的tomcat，结果依然是失败。
后来使用telnet 127.0.0.1 到shutdown的端口 发现失败；
tomcat停止的时候将SHUTDOWN指令发送给127.0.0.1:8005端口执行；
问题原来出在自己之前测试的时候把配置有127.0.0.1 IP的lo网卡给禁用了；
启用lo网卡，然后重新停止tomcat成功。o(∩_∩)o
解决步骤：
tomcat监听端口如下：
# netstat -napt |grep java |grep LISTEN
tcp 0 0 :::8080 :::* LISTEN 1317/java
tcp 0 0 ::ffff:127.0.0.1:8005 :::* LISTEN 1317/java
tcp 0 0 :::8009 :::* LISTEN 1317/java 报错如下：
# /usr/local/tomcat/bin/catalina.sh stop
