Sharp speed There may be many friends have not heard, not only can speed up Web Access, the official note for the sharp speed (serverspeeder) acceleration software is a ZETATCP acceleration engine software, can play a significant acceleration of the TCP acceleration technology, enhance the stability of vps/server connection, and effectively improve the bandwidth utilization of the server. But a lot of friends are based on Linux system CentOS 6.8, sometimes the situation can not install sharp speed, because the official centos6.8 not support the sharp speed, so centos6.8 want to install sharp speed will downgrade the core.

In addition, it is said that this thing can also improve the access speed of VPN, such as the tribe introduced before the VPS with mobile phones to build OpenVPN cloud-Free server graphics and text tutorial This article, if with the sharp speed (serverspeeder) This thing, speed will have a qualitative upgrade.

How to install sharp speed on Linux system CentOS 6.8

First, let's take a look at the official list of sharp-speed support cores:

The tribe here just intercepts a part of it, and you can view the official form, the address is: this is direct.

First we need to confirm our own kernel version, direct input command uname-a, i686 in output is 32 bits, x86_64 is 64 bits.

Download the 64-bit kernel:

wget http://ftp.scientificlinux.org/linux/scientific/6.5/x86_64/updates/security/kernel-2.6.32-504.el6.x86_64.rpm

Download the 32-bit kernel:

wget http://ftp.scientificlinux.org/linux/scientific/6.5/i386/updates/security/kernel-2.6.32-504.el6.i686.rpm

Take 32-bit systems as an example, we can RPM-IVH kernel-2.6.32-504.el6.i686.rpm--force the kernel after downloading, and then reboot reboot the system.

If an error such as error:failed Dependencies:kernel-firmware >= 2.6.32-504.el6 is needed by kernel-2.6.32-504.el6.x86_64 appears, Need to update firmware

Download kernel-firmware-2.6.32-504.el6.noarch.rpm, download the address is: from this direct.

Then execute RPM-UVH kernel-firmware-2.6.32-504.el6.noarch.rpm you will find the progress bar and then perform RPM-QA | grep Kernel-firmware found firmware installed successfully.

This will be successful if we execute the RPM-IVH kernel-2.6.32-504.el6.i686.rpm--force to install the kernel. If not, just forget it.

Summary

The method in the article originates from the network and is released by the free tribe.

Sharp Speed serverspeeder Acceleration software The tribe hasn't tried yet, the official also has the 20Mbps bandwidth of free package service, but the traffic is slightly larger site, basically a little bit less. Sharp speed currently only supports Xen and KVM architecture VPS, if you play free flow, you can go to try. Of course, Have to have their own VPS to do.
