The question leads to:

Install centOS7 on the virtual machine, configure Tomcat, and start successfully. But the Tomcat 8080 port cannot be accessed in the browser.

Reason:

Because CentOS 7 or RHEL 7 or Fedora, the default firewall is managed by firewalld, and firewalld is not open to port 8080, port 8080 open configuration is performed.

In versions prior to CentOs 7, iptables controlled the port of Linuxs.

After CentOS has been upgraded to 7, it is not possible to use iptables to control the port of Linuxs because Centos 7 uses firewood instead of iptables.

Solution:

1. Open port 8080 on firewalld

The command is as follows:

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

Command parsing:

-- zone # scope-- add-port=8080/tcp # add port. Format: Port / communication protocol-- permanent # is in effect permanently. If this parameter is not set, it will become invalid after restart.

2. Restart the firewall

The command is as follows:

Firewall-cmd-reload

3. Open an external browser and type http://centOS IP:8080 to see the Tomcat welcome interface!

These are the details that cannot be accessed by tomcat under linux. Please pay attention to other related articles for more information.
