How to solve the failure to open Huawei CVM port? If the CVM port failed to start, first check whether the port is open to the public. Change the settings of the CVM security group and add the ports you need to use.

The startup of the CVM port needs to be viewed from the operating system itself and the application. Take the Linux operating system as an example, ports below 1024 can only be started by root users, that is, you need to run sudo su-obtain root permission before enabling the service port.

The port cannot start, or it may be an application problem. It is recommended to use the application startup log to troubleshoot the causes of failure, such as port conflicts, configuration problems, remote access ports with non-default ports, or inconsistent port settings.

You can use port scanning tools to detect openness, such as nmap software. The CVM of centos system can be installed directly with yum, and windows can be downloaded by Baidu.
