Ubuntu14.04 switching cores to install sharp speed

Since the sharp speed only supports ubuntu14.04 64bit 3.13.0-24-generic core, most servers and VPS use the 3.13.0-3x (4x)-generic kernel by default, which leads to the inability of webmaster to install sharp speed to the server. This article is to show you how to replace the 3.13.0-24-generic kernel, so that the server can use the sharp speed.

1. First of all ensure that your server or VPS is a 64-bit system, sharp speed does not support any Ubuntu 14.04 32-bit system

2. To install the 3.13.0-24-generic kernel file:

1. 
   

   sudo apt-get install Linux-image-extra-3.13.0-24-generic

Copy Code

1. To view the currently installed kernel:
   
   

   Dpkg-l|grep Linux-image

Here we will go back to the 3.13.0-24-generic kernel and the kernel installed on the previous server, and all we have to do is uninstall the previously installed kernel.

1. Uninstall the other kernels you see in step 3rd:
   

   sudo apt-get purge linux-image-3.13.0-xx-generic linux-image-extra-3.13.0-xx-generic

xx Here is the 3rd step to see the current server or the VPS installed on the other kernel, note if the current server is not installed the latest kernel, uninstall will also install the latest kernel for the server In order for the server to use the 3.13.0-24-generic kernel supported by the sharp speed, we need to execute this command again to unload the latest installed kernel.

1. To update the GRUB system boot file:
   
   

   sudo update-grub

   
   
   

2. Restart the system:

   sudo reboot

Use after reboot

Uname-r

You can see that the server is already using the 3.13.0-24-generic kernel supported by the sharp speed, then you can install the sharp speed
