Posted on by

This is a guide on how to setup Cloudflare CDN with BigRock (similar for Bluehost,Godaddy, Dreamhost, Hostgator) for your website or blog . You can follow the steps below:

Step 1. Create an account with Cloudflare:

Go to https://www.cloudflare.com and click on the “Signup” button.

 

cloudlare signup

Fill in your details, tick on “Agree” and then click on “Create Account“.

cloudflare create account

Step 2. Add your website

Now, in the text box below, type your website address and then click on “Scan DNS Records“as shown below.

cloudflare add site and scan dns

It will take a few moments for the scanning to complete.

Once, the scanning is complete, click on “Continue“.

Now, click on “Continue” in the bottom corner:

cloudflare click continue

 

 

Step 3. Select Cloudflare Plan

Now, select the “Free Website” package as shown below and click on “Continue“.

 

select cloudflare free plan

Step 4. Get new name servers

Now, you will see the Cloudflare name servers as shown below. [This may vary for your website]

cloudflare name servers

As you see, for my website it is requesting to change the name server from

dns1.bigrock.in to linda.ns.cloudflare.com
dns2.bigrock.in to rob.ns.cloudflare.com

Also, also to remove the following nameservers:

dns3.bigrock.in 
dns4.bigrock.in 

[Note: The nameservers that you may see in your screen may be different.]

Step 4: Change your name servers to Cloudflare

Now, open up a new tab and login to your domain host panel (i.e. from where you bought your domain name from eg BigRock, Goddady, Hostgator, Bluehost etc). I have my domain from BigRock so I will be loggin in to my Bigrock account.

Now, click on the domain you need to change the name servers to.

 

bigrock select domain

Now, click on “Name Servers” 

 

bigrock manage name servers

 

 

And you will see your default nameservers as shown below:

Now, change your nameserver to the ones provided by cloudflare. In my case, after changing the nameserver, it will look like this:

 

cloudflare nameservers update

Now, click on “Update Name Servers“.

domain bigrock nameserver change success

Step 5: Verify in Cloudflare

Now, go back to your cloudflare tab and click on “Continue“.

cloudflare dns nameserver

It should show you show you a green banner with the status: “Active” as shown below.

 

cloudflare cdn active status[NOTE: If you the status does not show as “Active” then you can click on “Recheck Status” and it then should show that its “Active”]

[IMPORTANT: It would take about 24-48 hours for the DNS to get updated.]

And Voila! You have successfully configured Cloudflare CDN for your blog/website and should load faster.

Do check the  performance of your website after 24-48 hours and let me know in the comments sections below if there was any speed improvement.

How To fix “This kernel requires an x86-64 CPU, but only detected an i686 CPU. This processor is unsupported in RHEL 7.” when booting from VirtualBox

Posted on by

Error: This kernel requires an x86-64 CPU, but only detected an i686 CPU.
This processor is unsupported in RHEL 7. 

centos-boot-error

[Note: This tutorial is under the assumption that your physical CPU is 64-bit and your installed host OS is 64-bit and will only work in these circumstances.]

Cause:

This mainly happens due two reasons:

  1. If you have a 64-bit OS installed but the VirtualBox OS type is accidentally changed/set to 32-bit after installation.
  2. If Vt-X (Virtualization) is disabled in the BIOS. (This can happen if you reset your BIOS to default settings which may have disabled Vt-X  bit).

Solution:

Step 1: Right Click on the Centos/RHEL OS which is giving you the error and then click on “Settings“.

virtualbox settings

Step 2: In General Tab, check the OS Type and see if you are able to change to “Redhat 64-bit” and follow step 4.

change os type

Step 3: If you are only able to see 32-bit entries in the OS type list and your physical CPU supports 64-bit, this means that Vt-X is disabled in your BIOS. So, restart your PC and boot into your BIOS, enable Vt-X.

For reference, I have a Asus Maximus VII Ranger Motherboard and here is how I enabled Vt-X in my BIOS.

enable vt-x

[Optional: If your CPU supports Vt-d, enable that too, it will improve functionality and performance of your Virtual Machine. Some CPUs will not have the Vt-d function, if you dont have it then you can ignore it]

optional step to enabled vt-d

Step 4: Restart your computer and boot back your CentOS/RHEL VM and it should come right up.
