  2. Go to the detail page of ECS and click 【EIPs】 tab change IP

  3. Click 【Bind EIP】 button to complete this solution

Security Group​

A Security Group acts as a virtual firewall for Elastic Compute Service (ECS) instances to control inbound and outbound traffic and improve security. You can use security groups and security group rules to define security domains in the cloud.

Below is a sample for you how to Enable TCP:80 port on security group:

  1. Login to console, lis all ECS by 【Cloud Server Console】>【Security Group】

When there is only one website on the server, you can visit the website without binding domain. While considering the server security and subsequent maintenance, Binding Domain is necessary.

Steps for binding HUAWEI CLOUD domain are as follows:

  1. Connect your Cloud Server;
  2. Modify vhost configuration file,and change the server_name and proxy_pass if you want. 
    server
    {
    listen 80;
    server_name websoft9.yourdomain.com;  # Set your domain
        location / {
        proxy_pass  http://127.0.0.1:8880; # Set your port
    ...
    }
  3. Restart Nginx service 
    sudo systemctl restart nginx

Domain Beian​

If you ECS is created in China, and you want to use Domain for application, you must complete the Domain Beian for Government governance.
