1. Select Server System
As shown in the figure below, check the free package only in the left column to filter out the available server systems for the free package. Here we select Ubuntu Server 16.04 LTS (HVM), SSD Volume Type, and Ubuntu system version 16.04.
2. Select the virtual hardware of the instance
As shown in the figure below, select the second t2. micro type. It is selected by default, and does not need to be changed. Next step: Configure instance details.
3. Configure Instance Details
Select Enable in the Auto Assign Public IP option. Independent public IP must be available. Select Next: Add Storage.
4. Add Storage
Fill in the size with 30. The 30G storage volume is permanently free of charge for AWS. Select Next: Add a label.
5. Add Host Label
Adding a label is used to mark the host name. I skip this step and do not add a label. Select Next: Configure the security group.
6. Add Security Group
By default, you choose to create a new security group, and ssh rules have been added by default. (SSH is used by the computer to remotely log in to the server.) This step does not need to be set, but remains the default. Select Approve and Start.
7. Check the instance configuration and start
Check whether the previous instance configuration is appropriate. In the lower right corner, click Start. In the pop-up box, select Create a new key pair, enter the name of the key pair (to be named in English), click Download Key Pair, and download the key to the local computer to save it. Here, assume that the key name is example.pem and saved in the local directory/home/users, which will be used in the following tutorial.
SSH logs in to ECS remotely and resets the SSH configuration on the server to facilitate future login
After the instance is started, the instance panel is shown in the following figure. Record the independent public IP address of the instance, which is required for ssh login.

SSH login of the mac system
The mac system comes with the ssh tool. Open the terminal and enter the following command
Ssh - i/home/users/example.pem ubuntu @ Independent public IP
Then the terminal will prompt whether to create an ssh connection. Enter yes and press Enter.

Set the root administrator user password: sudo passwd root prompts to enter the password twice, and uses Enter to confirm each entry.
Switch to the root account: su root enters the password you just set, and then press Enter to confirm.
Set the password of the ubuntu user: passwd ubuntu prompts you to enter the password twice, and uses Enter to confirm each entry.

Win system login
Use xshell. In user authentication, select Password, fill in ubuntu for the user name, and fill in the password of the user set in the previous step. Click OK to log in to the server instance.
