I built a LAMP environment with Sakura VPS for learning, so I will summarize the procedure.

table of contents

Operating environment

OS : macOS Mojave 10.14.6 VPS OS : centOS

procedure

Apply for Sakura VPS

  1. Visit Sakura's website> VPS> Free trial for 2 weeks Add the server to the cart and apply.

  2. Log in with the ID and password provided in the email and log in to the VPS control panel.

  3. Settings> OS installation

This completes the process from applying for Sakura VPS to installing the OS.

ssh connection

Next, I will summarize the procedure for setting up an SSH connection to connect to a VPS on the Internet from a local PC.

1. Start Terminal and log in with root privileges

Start Terminal with your MAC.

Then connect with the following ssh command. The password was entered when the OS was installed.

$ ssh [email protected] address of VPS

2. Software update

$ yum update

3. Creating a general user

$ adduser jun1 #user added
$ passwd jun1 #password setting

Set to use sudo

$ visudo
wheel ALL=(ALL) ALL #Uncomment

Add jun1 user to wheel group

$ usermod -aG wheel jun1
$ groups jun1
jun1 : jun1 wheel

Check if you can log in with jun1

$ ssh [email protected] address of VPS
$password input

4. ssh key authentication settings

Start and run the terminal on your local PC

MAC$ ssh-keygen -t rsa -v
MAC$ ls ~/.ssh
config		id_rsa		id_rsa.pub	known_hosts

Connect to VPS with ssh

VPS$ mkdir .ssh
VPS$ chmod 700 .ssh

Transfer public key from local PC to VPS

Local PC


MAC$ scp ~/.ssh/id_rsa.pub [email protected] address of VPS:~/.ssh/authorized_keys
MAC$Enter VPS password

Log in to the server using the key

Local PC


MAC$ ssh -i ~/.ssh/id_rsa [email protected] address of VPS

Security settings for ssh connections

1. Port number setting

VPS

$ sudo vim /etc/ssh/sshd_config

Search for Port, delete #, 22-> 56789 (any number is acceptable)

2. Disable password authentication

Search for PasswordAuthentication and Change to no

3. Disable root login

Search with PermitRootLogin and change to no

4. Check the configuration file

VPS


$ sudo sshd -t #Check the configuration file for syntax errors.OK if nothing comes out
$ sudo systemctl restart sshd #Restart sshd

5. Firewall settings

VPS

>success
$ sudo firewall-cmd --permanent --add-service=ssh-56789

>ssh-56789

6. SSH operation check

Open another tab without closing the terminal opened above
