Understanding Rocky Linux

Rocky Linux is a community-driven distribution designed to be a downstream alternative to CentOS. It is particularly popular for servers due to its stability and performance. Before diving into the setup process, let’s explore some of its key features:

Advantages of Using Rocky Linux

  • Community Support: Backed by a strong community, Rocky Linux ensures reliable support and continuous development.
  • Enterprise-Ready: Ideal for server environments, it offers enhanced security and performance.
  • Familiarity: For those who have worked with CentOS, the learning curve is minimal, making it an excellent choice for existing users.

Setting Up Your VPS

The first step in setting up your VPS on Rocky Linux is to choose a hosting provider. Below are some popular options:

  • DigitalOcean
  • Vultr
  • Linode
  • Amazon Lightsail

1. Choose Your VPS Plan

When selecting a VPS plan, consider the following factors:

  • CPU and RAM: Assess your workload demands to determine the necessary resources.
  • Storage: SSD storage provides better performance compared to HDD.
  • Location: Choose a data center close to your target audience for reduced latency.

2. Accessing Your VPS

Once you’ve created your VPS, you’ll typically receive an email with your server’s IP address and login credentials. Use SSH to connect to your server. Open a terminal on your local machine and execute:

ssh root@your_server_ip

Replace your_server_ip with your server’s actual IP address.

Initial Setup and Configuration

1. Update the System

Once logged in, the first step is to update the package repository and install available updates. Run the following commands:

sudo dnf updatesudo dnf upgrade

2. Setting Up a Firewall

A firewall is crucial for securing your server. You can use firewalld which comes pre-installed in Rocky Linux. Here’s how to set it up:

  1. Start firewalld: sudo systemctl start firewalld
  2. Enable firewalld: sudo systemctl enable firewalld
  3. Open essential ports: For example, to allow SSH:

    4. sudo firewall-cmd --permanent --add-service=ssh

  4. Reload firewall: sudo firewall-cmd --reload

User Management and Security Hardening

1. Create a New User

Logging in as root is risky; it’s good practice to create a separate user. Use the following commands:

adduser newuserpasswd newuserusermod -aG wheel newuser

2. SSH Key Authentication

To enhance security, use SSH key authentication:

  1. Generate a key pair on your local machine:ssh-keygen -t rsa -b 4096
  2. Copy your public key to the server:ssh-copy-id newuser@your_server_ip
  3. Disable root login by editing the SSH config:sudo nano /etc/ssh/sshd_config

3. Install Fail2Ban

To protect against brute-force attacks, installing Fail2Ban is recommended. Install it with:

sudo dnf install fail2ban

Common Tools and Applications

After the initial setup, consider installing the following applications based on your needs:

  • Web Server: Apache or Nginx for hosting websites.
  • Database Server: MySQL or PostgreSQL for database management.
  • FTP Server: Vsftpd to enable file transfers.

Example: Installing Nginx

  1. Install Nginx:sudo dnf install nginx
  2. Start Nginx:sudo systemctl start nginx
  3. Enable Nginx on boot:sudo systemctl enable nginx

Best Practices for Maintaining Your VPS

  • Regular Backups: Always back up your data regularly.
  • Update Software: Keep your software updated to protect against vulnerabilities.
  • Monitoring: Use tools like Nagios or Prometheus to monitor server performance.

Troubleshooting Common Issues

If you encounter problems, consider the following common troubleshooting steps:

  • Check network connectivity with ping.
  • Inspect configuration files for typos.
  • Use the systemctl command to check the status of services.

Conclusion

Setting up your VPS on Rocky Linux doesn’t have to be intimidating. By following the steps outlined in this guide, you can create a secure and efficient server environment tailored to your needs. Remember to practice good security habits and regularly maintain your system to ensure optimal performance.
