The following guide was created to help you setup Cloudflare for your Website and configure SSL connexion encryption for your visitors/Cloudflare as well as in between Cloudflare and your PlanetHoster hosting. The connexion between your visitors and CloudFlare will be encrypted by Cloudflare’s SSL and the connexion between Cloudflare and your Hosting will be encrypted by the Let’s Encrypt certificate PlanetHoster has provided you. It all boils down to creating an account at CloudFlare, adding the website to your CloudFlare account, changing the Nameservers of your domain name to those of CloudFlare, configuring the encryption so that it is SSL from one end to the other and finally the installation and configuration of the CloudFlare plugin for WordPress.
CloudFlare offers you CDN and anti-DDOS services free of charge for all your websites. The first step is to create an account at CloudFlare.
1- Connect to https://www.cloudflare.com/
2- At the top right, click on the “Sign up” button:
3- Once your registration request has been completed, check your email inbox. A confirmation message from CloudFlare will have been sent to you, you will need to click on the confirmation link in the latter in order to start using your CloudFlare service.
Add the website to your CloudFlare account
1- Log in to your CloudFlare account
2- In your dashboard, click + Add your site
3- Then choose the desired service, the free service is very good if you want to use the Content Delivery Network (CDN) as well as CloudFlare anti-DDOS protection.
4-CloudFlare will then scan the website to find the DNS zone currently in use, make sure the entries match with what you have in your real DNS zone and then click the continue button:
Change the nameservers of your domain name
You have now successfully added your site to your CloudFlare account. This section will walk you through the update of NameServers for your domain name with those of CloudFlare required to take advantage of CloudFlare.
In the next step, CloudFlare indicates the Nameservers to set up:
If your domain name is not registered at PlanetHoster you can check with the technical support of your actual registrar how to apply the new Nameservers or perhaps even consider transferring it with PlanetHoster.com? Our support team is always glad to assist you very quickly!
Changing Nameservers for your domain name may take up to 24 hours to spread completely! After that, your CloudFlare service is activated successfully!
Configure CloudFlare SSL mode to use Let’s Encrypt between CloudFlare and PlanetHoster
Congratulations! Your site is now protected with CloudFlare, but there still needs to adjust the SSL configuration. By default, CloudFlare will have installed a valid SSL certificate that covers the link between your site visitors and CloudFlare, but the connection between CloudFlare and your PlanetHoster Host will not. For that, we will have to go ahead and set up the righteous SSL mode in our Cloudflare Dashboard.
1- In your CloudFlare Dashboard, click on the option named “Crypto”:
2- You will find the SSL configured by default to “Flexible” this option ensures that the connection between CloudFlare and your visitors is secure but not the connection between CloudFlare and your PlanetHoster hosting, To correct this, adjust the SSL option to Full or Full (strict).
3- That’s it! There is no “save” button in this interface, changes are applied as soon as you order them from the drop-down menu! After that, please allow 24 hours so that Full mode (Full or Full) is taken into account and that the connection between CloudFlare and your PlanetHoster hosting is also encrypted by the Let’s Encrypt! certificate.
