Huawei Cloud Yaoyun Server L instance evaluation | StackEdit Chinese version online Markdown note-taking tool

1. Introduction to Yunyao Cloud Server L Instance

1.1 Introduction to cloud server

As the era of cloud computing further deepens, more and more small and medium-sized enterprises and developers need an easy-to-use, high-power and efficient cloud computing infrastructure product to support their business operations and innovative development. Based on this demand, Huawei Cloud has launched a new product of Huawei Cloud server instances. Huawei Cloud servers have the four advantages of being smart and non-stuck, affordable and easy to use, easier to get started, and worry-free management, helping you get to the cloud quickly!

From the end of August to mid-October, if you participate in the evaluation activity of Huawei Cloud Server, you can get a coupon of 54.99 yuan. You can purchase the Huawei Cloud Yaoyun Server L instance and lightweight server for only 0.03yuan per month.

1.2 Application scenarios

Yunyao Cloud Server L instances are suitable for supporting lightweight, low-load and moderately visited application scenarios such as small websites, web applications, blogs, forums, and cloud development environments.

• E-commerce store management: quickly build an independent foreign trade station and store management environment to provide stable and high-quality services to customers at home and abroad.
• Website building: Provides commonly used website building application templates to quickly build websites that meet business needs, such as corporate official websites, information, blogs, forums, e-commerce, etc.
• Mini program backend: Suitable for building WeChat mini programs and public account backend services to reduce maintenance costs and allow users to focus on business development.
• Small games: Help customers build PC stand-alone games, casual games, etc., quickly go online and have stable performance.
• Development and testing: Suitable for building ready-to-use remote development and testing projects in the cloud, running scheduled tasks, automatic tasks, etc.
• Cloud learning: Help students and developers do some experiments, papers, etc. in the cloud.
• Build blogs/forums: It is convenient for individual developers to build blogs and forums, and it is cost-effective.

1.3 Support mirroring

mirror	Introduction
system image	Only the initial operating system is included, and no application data or environment configuration is included. After using a system image to create a cloud server, the server will have a pure operating system environment. You can install applications by yourself based on the business needs of the instance.
Application image	Contains the application and related initialization data, the operating environment and operating system required by the application. After you create a cloud server using an application image, you can directly use the preset application or customize the application configuration according to actual business needs. Reduces the steps of application uploading and installation.

If you want to know more, please refer to the official documentation

2. Yunyao Cloud Server L instance configuration

2.1 Reset password

After the purchase is completed, a text message will be sent through your cloud server information, focusing on the public IP address and user name. First we need to open your server console, complete the password

reset, check Automatically restart, and click OK.

2.2 Server connection

• Method 1 : Log in using the VNC method provided by the console

• Method 2 : Use Putty, Xshell and other tools to log in to the Linux elastic cloud server.
  a) Download and install the login tool, such as Putty.
  b) Enter the elastic public IP.
  c) Enter the username: root, password, and click "OK".

• Method three : Use the Linux/Mac OS system host to log in to the Linux elastic cloud server.
  a) Execute the connection command.
  ssh elastic public IP
  , for example: ssh 123.xxx.xxx.456
  b) Enter the user name: root, password, and log in to the server.

I personally use MobaXtermthis software, add SSH connection, output 公网IP, user name and port (default 22), and connect.

2.3 Security group configuration

A security group is a logical grouping that provides access policies for cloud servers in the same VPC. Users can define various access rules in the security group. When the cloud server joins the security group, it will be protected by these access rules.

The system creates a default security group for each network card by default. The rules of the default security group are to allow all data packets in the outbound direction and restrict access in the inbound direction. You can use the default security group or create a custom security group if needed.

You mainly need to fill in the priority (fill in 1 by default) and protocol port information (generally select the port that your project needs to expose), and click OK for other defaults. Security group configuration is mainly to expose ports to the external network for access.

If you are still unclear, you can refer to the document: Security Group Configuration Example

• Configure security group

On the security group management page of Huawei Cloud Yaoyun Server L instance, add inbound rules. Next, when we start the service, we need to listen to port 9090, so we add the security group as the TCP:9090protocol port.

• Start service

You can use the following command to start the service

docker run -d -p 9090:9090/tcp mafgwo/stackedit

Or docker-composestart it through the method, first create the filedocker-compose.yml

version: "3.7"
services:
  stackedit:
    image: mafgwo/stackedit:5.15.17-1
    container_name: stackedit
    environment:
      - LISTENING_PORT=9090
      - ROOT_URL=/
      - USER_BUCKET_NAME=root
    ports:
      - 9090:9090/tcp
    network_mode: bridge
    restart: always

About environmentenvironment variables

environment variables	default	describe
LISTENING_PORT	8000	Internal server listening port
ROOT_URL	/	The root URL to use, useful when used with reverse proxies
USER_BUCKET_NAME	stackedit-users	User bucket name

If you save the above code snippet in a file called docker-compose.yml, you can simply run from the same folder to docker compose up -dautomatically pull the stackedit image and create and start a container. upIndicates starting the service and -dexecuting it in the background.

docker-compose up -d

• Check container status

Check the StackEdit container status to ensure that the container starts normally

root@hcss-ecs-f632:~/edit# docker ps
CONTAINER ID   IMAGE                        COMMAND                  CREATED          STATUS                    PORTS                                                 NAMES
