The following error message appears when you execute the close Tomcat command on the server

[root@server classes]# service tomcat restart

Then check the relevant information. On the stack overflow website, it says that it may be a CentOS firewall problem. Check the firewall configuration file, and the 8005 port has been configured. Then close the firewall, and it is still connection refused

Then use the telnet command to test. First test telnet 127.0.0.1 80, normal, then telnet 127.0.0.1 8005, normal, later test telnet localhost 80, abnormal connection refused, telnet localhost 8005, also abnormal, connection refused

It should be the problem of localhost parsing

#vim /etc/hosts

View the local hosts configuration file

 

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

Modify localhost, add it to 127.0.0.1, and change it to

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

Test #sh shutdown.sh, now it can shut down Tomcat normally and no longer prompts Connection refused.
