# “Justonemoreyearicanfeelit”: Managing Your Growing Infrastructure with Ease

Welcome to our latest guide, designed for seasoned DevOps engineers and system administrators who are feeling the strain of managing a growing infrastructure. This post will focus on the essential practices for efficient infrastructure management, specifically addressing domain registration and renewal - a challenge many of you might relate to, given the title. Let’s dive in!

Prerequisites

Before we begin, ensure your system meets the following requirements:

• Operating System: CentOS 7 or Ubuntu 18.04+ (64-bit)
• Hardware: Minimum 2GB RAM and 2 CPU cores
• Network: Stable internet connection with port 53 open for DNS traffic
• Software: curl, jq, and a domain registration client like pyDNS (installation guide)
• User Permissions: Root access or sudo privileges

Installation & Setup

Registering a Domain with pyDNS

1. Install Python3 and pip:

   sudo yum install python3 -y
   curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py && sudo python3 get-pip.py
   

2. Install pyDNS:

   pip3 install pydns
   

Configuring pyDNS

Create a configuration file ~/.pydns.conf with the following content:

[general]
username = YOUR_REGISTRAR_USERNAME
password = YOUR_REGISTRAR_PASSWORD
server = ns1.YOUR_REGISTRAR.com

[domain]
DOMAIN.party =
  registrar = ns1.YOUR_REGISTRAR.com
  contacts =
    admin = "Admin Name <admin@example.com>"
    technical = "Tech Name <tech@example.com>"
    billing = "Bill Name <bill@example.com>"

Replace YOUR_REGISTRAR, YOUR_REGISTRAR_USERNAME, and YOUR_REGISTRAR_PASSWORD with your registrar’s details. Update the DOMAIN.party section with your desired domain names.

Registering a Domain

Register a new domain using:

pydns register DOMAIN.party -c ~/.pydns.conf

Replace DOMAIN.party with the actual domain you want to register.

Configuration

Configure your nameservers, DNS records, and auto-renewal settings as needed. For more information, consult your registrar’s documentation or our extensive DNS management guide.

Security Hardening & Performance Optimization

Follow best practices such as setting strict SSL/TLS requirements, configuring SPF and DKIM records, and implementing caching for optimal performance.

Usage & Operations

Perform common operations like modifying DNS records, renewing domains, or transferring domain ownership using the pydns command with various flags.

Troubleshooting

Refer to your registrar’s documentation for assistance with common issues such as domain transfers or resolving DNS propagation delays.

Conclusion

With this guide, you now have the skills and knowledge to manage your growing infrastructure efficiently, including registering and renewing domains with ease. Next steps include exploring advanced topics like DNS clustering, load balancing, and integrating your infrastructure with popular DevOps tools.
