What should I do if I cannot access Tomcat after opening it on CentOS?

Solution to the inability to access CentOS after opening Tomcat:

First check whether the firewall is started:

firewall-cmd --state

If "running" appears, the firewall is running. If there is no prompt, enter the command to open the firewall:

systemctl start firewalld

Then enter the command to check whether port 8080 is opened by the firewall (if "8080/tcp" appears "Indicates that the port is opened):

firewall-cmd --permanent --zone=public --list-ports

If nothing is prompted, it means that port 8080 is not opened; you need to execute the command to open port 8080 (if "success" appears, it means the addition was successful):

firewall-cmd --zone=public --add-port=8080/tcp --permanent

Restart the firewall:

firewall-cmd --reload

Finally, verify whether the opened 8080 port is effective (you can also directly access tomcat through the browser to test):

firewall-cmd --zone=public --query-port=8080/tcp

If "yes" appears , indicating that the opening is successful, so that you can access tomcat normally!
