To register an account and create a server on the overseas version of Amazon Cloud, you can choose data centers in Singapore or Japan for faster speeds. When creating a key, ensure you select "create new key" and download it. For local operations: 1. Move the downloaded key to the desired directory and rename it (e.g., to ec2). Command: `mv /Downloads/ec2.pem ~/.ssh/ec2.pem` 2. Set permissions: `chmod 400 ec2.pem` 3. Connect using SSH: Command: `ssh -i {path_to_your.pem_file} ec2-user@{instance_IP_address}` Example: `ssh -i ~/.ssh/ec2.pem centos@1.2.3.4` (modify the username based on your server's OS).

Account Registration and Server Creation#

For the overseas version of Amazon Cloud, the server can be located in Singapore or Japan, which offers relatively faster speeds.

It is important to note to select "Create a new key" when creating the key and to download and save it properly.

Local Operations#

Move the file
Save the downloaded key to the download directory and rename it; I renamed it to ec2 and moved the key file. If there is no relevant directory, you can create one yourself.

mv ~/Downloads/ec2.pem ~/.ssh/ec2.pem

Set permissions
chmod 400 ec2.pem
Connect
ssh -i {the full path of your .pem file} ec2-user@{instance IP address}

ssh -i ~/.ssh/ec2.pem centos@1.2.3.4
Note that the name before the @ needs to be modified according to your server system; mine is centos7, please modify it accordingly for other systems!
