5. Configure the firewall

Alibaba Cloud's firewall is turned off by default, but you can also check whether the firewall is turned off.

Run this command to view the firewall status: systemctl status firewalld

In this case, the firewall is turned off, because the status is:dead

If the following situation means that the firewall is open, there is no need to take the step of opening the firewall

5.1 Turn on the firewall

Run: systemctl start firewalld

If there is no prompt, it means the opening is successful. You can run systemctl status firewalld and check the startup status again. This time it should be booting.

5.2 Open 8081 port

run:

firewall-cmd --permanent --add-port=8081/tcp

--permanent : Means permanently effective

5.3 View all open ports

run:

firewall-cmd --permanent --list-port

If port 8081 is already open, you can run the project first
