In today’s digital landscape, safeguarding and optimizing your website or application is crucial for ensuring a seamless user experience and maintaining a strong online presence. Cloudflare, a renowned content delivery network (CDN), offers a comprehensive suite of services, including DDoS protection, caching, and website optimization, to empower you in achieving these goals. By configuring Cloudflare in front of your website or application, you can effectively enhance its performance, security, and reliability.
Setting Up and Installation
Creating a Cloudflare Account
The first step in harnessing Cloudflare’s capabilities is to create an account. Navigate to the Cloudflare website and click on the “Sign Up” button. Enter your valid email address and create a secure password. Verify your email address by checking your inbox for a confirmation message. Once verified, you will be directed to the Cloudflare dashboard.
Adding Your Website to Cloudflare
To connect your website to Cloudflare, click on the “Add Site” button and enter your website’s URL. Cloudflare will scan your website to identify its DNS records.
Choosing a Cloudflare Plan
Cloudflare offers a range of plans, catering to diverse needs and budgets. Select the plan that best aligns with your requirements, ensuring you have access to the features you require. For this guide, we will proceed with the “Free” plan.
Updating Your DNS Settings
After selecting your plan, Cloudflare will display a list of DNS records associated with your website. Verify the accuracy of these records or remove any unnecessary ones. Click on the “Continue” button to proceed.
Cloudflare will provide you with new nameservers that need to be updated on your domain registrar’s website. This typically involves accessing the Customer Control Panel (CCP) at my.contabo.com for Contabo customers. Navigate to “DNS Zone Management” to update the DNS settings.
For users with domain registrars other than Contabo, log in to their respective domain registrar’s website and update the nameserver records with the ones provided by Cloudflare.
Verifying Your DNS Settings
Once you have updated the DNS settings, return to the Cloudflare dashboard and click on the “Done, Check Nameservers” button. Cloudflare will verify the accuracy of the updated DNS settings. This process may take some time, so exercise patience. Upon successful verification, Cloudflare will send you an email notification.
Connecting Your Server with Your Domain on Cloudflare
After verifying the DNS settings, it’s time to connect your server with the Domain you set up at Cloudflare. Follow these steps:
-
In the left menu, select “Websites”.
-
Click on your Domain.
-
In the left menu, choose “DNS”.
-
To connect your server with this domain, click on “Add record”.
-
Leave the “Type” as “A”.
-
For “Name”, enter your Domain (e.g., test.com).
-
For IPv4 address, enter the IPv4 Address of the server you want to connect with your domain. (For Contabo users, this can be found in the Customer Control Panel –> Your Services.)
-
Click on “Save”.
