#Vultr#Debian 8 and Centos7 system VPS installation cracked version Ruisu graphic tutorial

Introduction to Ruisu functions

Ruisu is a TCP network acceleration software that can be installed on Linux and Windows servers. After installation, it can improve network connection stability, bandwidth utilization, low access failure rate, etc., thereby improving the server Network access speed. Ruisu cannot increase the bandwidth, it can only improve the stability and utilization of the network, but this is also very good for friends who use foreign VPS to build their websites.

Vultr needs no introduction here. Currently, all the built-in Linux systems of Vultr VPS cannot be directly installed with Ruisu, so we need to replace the kernel for installation. Today, the blogger introduces the installation methods of the two systems. One One is the Debian 8 x64 (jessie) system, and the other is the Centos 7 x64 system.

Debian 8 system installation sharp speed

We need to install the Debian 8 x64 (jessie) system first, then use Xshell to connect to your VPS and view the current kernel. The view command is:

uname -a

What is currently displayed should be:

linux-image-3.16.0-6-amd64

The version we need to downgrade to is:

linux-image-3.16.0-4-amd64

Tutorial on downgrading the kernel: Execute the following script

wget http://security-cdn.debian.org/pool/updates/main/l/linux/linux-image-3.16.0-4-amd64_3.16.43-2+deb8u5_amd64.deb

Install 3.16.0-4 kernel

dpkg -i linux-image-3.16.0-4*.deb

To delete the original cores, first take a look at them and show them all

dpkg -l|grep linux-image

Delete the original kernel

apt-get -y remove linux-image-3.16.0-7-amd64

When deleting, a white-blue screen will appear, asking you to choose yes or no. Be sure to choose no, so that the original kernel will be deleted. Update grub system boot files

update-grub

Restart VPS

reboot

Wait for a while and reconnect to the VPS. Check the kernel version uname -a and you will see that it has been downgraded. Now you can install Ruisu.

wget --no-check-certificate -O appex.sh https://raw.githubusercontent.com/0oVicero0/serverSpeeder_Install/master/appex.sh && chmod +x appex.sh && bash appex.sh install

Enter the above script. If you are prompted in the middle to continue, just press Enter.

CentOS 7 system installation Ruisu

The kernel of vultr's centos7 system does not support Ruisu installation. We can check the kernel in advance.

uname -r

Displayed as follows:

We need to install 3.10.0-229.1.2.el7.x86_64, enter the following script:

rpm -ivh http://soft.91yun.org/ISO/Linux/CentOS/kernel/kernel-3.10.0-229.1.2.el7.x86_64.rpm --nodeps --force

The output results are as follows:

Let’s check again whether it was successful, enter:

rpm -qa | grep kernel

Then you may restart and query the kernel again:

reboot uname -r

It shows that the replacement has been successful.

Now you can install Ruisu.

wget -N --no-check-certificate https://github.com/91yun/serverspeeder/raw/master/serverspeeder.sh && bash serverspeeder.sh

The following errors may be reported:

serverspeeder.sh: line 141: ifconfig: command not found serverspeeder.sh: line 144: ifconfig: command not found The name of network interface is not eth0, please retry after changing the name

We only need to install ifconfig, enter:

yum install net-tool

After the installation is complete, enter the script to install Ruisu and wait a few seconds for success.

The above is the process of installing Ruisu on the two systems of vultr. If you have any questions, you can leave a message to me directly.

Summary: Whether you are using vultr’s VPS to build a website or run data, it is essential to install acceleration software. This article mainly introduces the installation of Ruisu. Ruisu is only suitable for KVM architecture VPS installation. If your VPS is OpenVZ For the architecture, you can try to install a magic modified BBR, and the blogger will share it with you later!
