How to Setup CloudFlare CDN for WordPress Blog

Introduction

One of the most important parts of building your websites, is making sure they load fast. It’s not a surprise – these days web page loading speed is an important factor for search engine rankings. There are many ways to speed up WordPress websites, for example, using a caching plugin like WP Super Cache, optimizing images or using a Content Delivery Network (CDN). The best results can be achieved using all these methods in conjunction.

In this tutorial, you will learn to setup CloudFlare for your WordPress website hosted on Hostinger WordPress hosting and configure WordPress CloudFlare plugin.

What is CloudFlare CDN

CloudFlare is a content delivery network which acts as a proxy between the website and visitor. It serves cached static content from the nearest location (CloudFlare has multiple servers around the globe), thus making website loading speed faster. Moreover, CloudFlare handles all requests to a website and can offer more useful services compared to traditional CDN:

• DDoS attack mitigation
• Analytics on all requests made to a website
• Easy SSL certificate installation
• Network gateway between protocols

Step 2 — Adding Domain Name to CloudFlare

After you have signed up with CloudFlare, you will be prompted with add your website window. Enter your website domain name and click on Scan DNS Records button in order to proceed.

Step 3 — Checking DNS records for your domain name in CloudFlare

After the scan has been finished, you will be prompted with your domain name DNS details. In this step, you can enable or disable CloudFlare for specific subdomains. Orange Cloud enables the CloudFlare and Grey Cloud disables the CloudFlare for a specific DNS record.

It’s recommended to enable CloudFlare for your naked domain name and www subdomain (as displayed in the picture). This way CloudFlare will work on both www and non-www versions of your domain. Once you are done, press Continue button to proceed to the next step.

IMPORTANT: It’s not recommended to enable CloudFlare for cpanel, mail, ftp or any other system reserved subdomains as it can result various DNS issues.

Step 4 — Pointing your domain name to CloudFlare nameservers

In this step, you will be asked to choose CloudFlare plan. Select a free plan and press Continue button again.

Now you will be given CloudFlare nameservers. Login to your domain registrar control panel and update your domain nameservers to CloudFlare nameservers. If you are not sure how to change your nameservers, you can follow this tutorial.

Once again, press Continue button.

Note that it may take up to 72 hours for DNS to propagate worldwide. Once nameservers update has been completed, you will receive an email confirmation message from CloudFlare. You can also check status on CloudFlare website. Your website will not face any downtime during this process.
