I decided to build a VPC environment first and then set up an EC2 environment in it. Basically, work according to this blog article.
Only the security group has been changed as follows according to the purpose of use this time.
Create an EC2 environment on the VPC environment created in ①. This work also referred to this blog article.
This time I wanted to create an environment that can be created with a free usage frame, so the configuration is as follows
$ sudo vi /etc/ssh/sshd_config ###Add the following around 22 lines(Port number specified in ①) Port 2**** ###After saving $ sudo service sshd reload
###New user creation(root privileges) # useradd newuser # passwd newuser ###SSH settings(root privileges) # cd /home/newuser/ # mkdir .ssh # chmod 700 .ssh # chown newuser:newuser .ssh ###Send the public key here with SCP # mv /home/ec2-user/id_rsa.pub .ssh/authorized_keys # chmod 600 .ssh/authorized_keys # chown newuser:newuser .ssh/authorized_keys ###Give permission to sudo # usermod -aG wheel newuser ###In another window"newuser"Log in as. After that, operate on the screen on the new user side $ sudo su - ###After confirming that you can become root, ec2-user deleted # userdel ec2-user
