Catalina.stop: Connect refused解决过程

在服务器上执行关闭Tomcat命令是出现下面的错误信息

[root@server classes]# service tomcat restart
Stopping Tomcat service:  Using CATALINA_BASE:   /opt/tomcat
Using CATALINA_HOME:   /opt/tomcat
Using CATALINA_TMPDIR: /opt/tomcat/temp

然后排查相关信息，在Stack Overflow网站上上面说可能是CentOS防火墙的问题，查看防火墙配置文件，8005端口已经配置好了。然后关闭防火墙，依然是Connection refused

然后使用telnet命令测试。首先测试telnet 127.0.0.1 80，正常然后telnet 127.0.0.1 8005，正常，后来测试telnet localhost 80，异常出现Connection refused，telnet localhost 8005，也是异常，Connection refused。

应该就是localhost解析的问题了。

#vim /etc/hosts

查看本地hosts配置文件。

127.0.0.1   IT2YWMHA01 localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

修改localhost，将其添加到127.0.0.1下面，修改后为

127.0.0.1   IT2YWMHA01 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost.localdomain localhost6 localhost6.localdomain6

测试#sh shutdown.sh，现在可以正常关闭Tomcat，不再提示Connection refused。
