This article is to share with you about how CentOS7 opens port 8080. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Centos7 has started to use firewall as a firewall instead of iptables, so opening port 8080 is different, so how do you open port 8080?

The method is as follows

1. Connect to the centos7 server

2. We can enter a command to check the status of the firewall

Firewall-cmd-state

3. If the previous step is turned off, enter the command:

Systemctl start firewalld.service

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 the port 808080th tcp to the protocol: permanently take effect. If this parameter is not available, it can only be maintained for the current service life cycle and expire after restart.

6. Enter the command to restart the firewall

Systemctl restart firewalld.service

7. Enter the command to reload the configuration

Firewall-cmd-reload
