1.4 Support mirroring

mirror	Introduction
system image	Only the initial is included 操作系统, not any 应用数据sum 环境配置. 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 applications and related 初始化数据、应用所需的运行环境及操作系统. 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.

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

3.4 Use of memos

After successful access, click Sign into register an administrator account, set the user name and password to register.

After completing the registration, log in to enter the administrator account. The administrator account is the administrator of this service and can also use the memo function as an ordinary user. Specific interface function introduction:

• Avatar bar: personal homepage, RSS subscription, about, logout
• Left sidebar functions: homepage, daily review, resource library, exploration, archiving, settings
• Intermediate subject: 编辑部分: label, upload file, to-do, code snippet, access permission, 展示部分: display added memo
• Right sidebar functions: global search function, calendar mark, all tags

For the convenience of reading, first 设置 - 偏好设置 - 语言modify it to Simplified Chinese

Add a plain text memo

add a picture

Add a piece of code, and each memo also supports pin, edit, quote, archive, and delete functions.

The files we uploaded are displayed in the resource library

Click on the personal avatar and select Profileto view all the contents of the personal homepage

There are also many setting functions. We can set 我的账号avatars, usernames and passwords. As an administrator account, we can view registered ones. 成员By default, only administrator accounts can add users and passwords, and they cannot register by themselves.

In order to realize the user's self-registration and login, it can be done in 系统the settings .允许用户注册

We try to register an ordinary user by ourselves, enter the user name and password, click register first and then log in. Entering the

ordinary user interface, we still set the language to Simplified Chinese. The setting function for ordinary users has many fewer configuration items, but the memo function is still the same.

全部可见When we set the access permission of the memo , we can 探索see this memo again

. Let’s check the structure of the memos mapping file path.

root@hcss-ecs-f632:~/memos/memos# ls
assets  memos_prod.db  memos_prod.db-shm  memos_prod.db-wal

• assetsDirectory used to store files uploaded to the resource library
• memos_prod.dbUsed to store personal user data to facilitate data migration

The personal use of memos memos is just the above. More functions and configurations need to be explored by yourself.
