Initial VPS Server Setup Checklist
- 1 Connect via SSH
Open your terminal and connect to your instance using the root credentials or SSH keys supplied by your hosting provider:
ssh root@your_server_ip - 2 Update the System Package Repository
Refresh package listings and apply outstanding patches depending on your operating system architecture:
Ubuntu / Debian:apt update && apt upgrade -yCentOS / AlmaLinux / RHEL:dnf update -y - 3 Configure Server Hostname
Map a Fully Qualified Domain Name (FQDN) targeting your virtual instance:
hostnamectl set-hostname yourserver.yourdomain.com - 4 Create a Sudo Non-Root Deployment User
Avoid daily root logins by setting up an isolated user space with root privileges:
adduser deployuserAssign Permissions (Ubuntu/Debian):usermod -aG sudo deployuserAssign Permissions (CentOS/AlmaLinux):usermod -aG wheel deployuser - 5 Set Up SSH Key Authentication
Execute this command from your local workstation's terminal to mirror your cryptographically secure public identity onto the host:
ssh-copy-id deployuser@your_server_ip - 6 Configure the Firewall Framework
Ensure ports are blocked by default while explicitly verifying that your current SSH connection is whitelisted:
Ubuntu (UFW):ufw allow OpenSSHCentOS / AlmaLinux (firewalld):
ufw enablefirewall-cmd --permanent --add-service=ssh
firewall-cmd --reload - 7 Set the Correct Timezone
Synchronize log timelines with your specific operational timezone framework:
timedatectl set-timezone Asia/Kolkata - 8 Install Essential Environment Utilities
Equip your instance terminal with essential network tools and basic monitoring runtime software:
Ubuntu / Debian:apt install -y curl wget git vim htop unzip fail2banCentOS / AlmaLinux:dnf install -y curl wget git vim htop unzip fail2ban - 9 Disable Root SSH Authentication
Important: First, ensure your custom user account can successfully open an independent sudo session. Then, access your configuration configuration environment:
Edit file:/etc/ssh/sshd_configand modify key property to: PermitRootLogin noApply modification parameters immediately by executing a system daemon refresh:
systemctl restart sshd
