4. Open port 8080 and enter the command:

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

5. Let's explain the last command:

-- zone=public: indicates that the scope is public

-- add-port=8080/tcp: add port 8080 of tcp protocol

-- permanent: permanently effective. If this parameter is not available, it can only be maintained for the current service life cycle and expire after restart.
