1.Create an AWS EC2 Instance: First, you need to create an EC2 instance on AWS. You can do this through the AWS console or using the AWS command line interface (CLI). Make sure to select an instance type, choose the operating system and security settings, and create a key pair to access the instance.

2.Connect to the instance: To connect to your instance, you will need to use SSH (Secure Shell) client software. On Windows, you can use a tool like PuTTY. On Linux or macOS, you can use the Terminal. You will need to use the key pair you created in step 1 to authenticate and log in to the instance.

3.Update the server: Once you are logged in, you should update the server to ensure it has the latest security patches and software updates. Use the appropriate commands for your operating system to update the packages.

4.Install and configure the software: Next, install any required software and configure it to your needs. This will depend on the purpose of your server, but common examples might include web servers like Apache or Nginx, databases like MySQL or PostgreSQL, or application servers like Tomcat or Node.js.

5.Set up firewalls and security: Finally, make sure to configure any necessary firewalls and security settings to protect your server from unauthorized access. This might include configuring the built-in AWS security groups, setting up a firewall like iptables, or using a security tool like fail2ban to block malicious traffic.

1.AWS does not provide an account password login method by default, only through the pem file click here to see how to change root login
2.ssh -i “xxxx.pem” ec2-user@ec2-54-138-22-111.ap-northeast-1.compute.amazonaws.com, the domain name may be too long in the mac system.
If you use centos, the default login account name is centos, the same as creating root permissions
