CentOS6.8 replace kernel with acute Vultr

CentOS6.8 replace kernel with acute Vultr

Although there are other VPS in hand, but in contrast, Vultr has a Japanese data center, which has good configuration, low price, sufficient bandwidth, and various advantages, so it is a pity to leave it alone.

Let's use it. a kvm-based VPS cannot be installed with acute speed! As it happens, the Vicer hacker recently released the "re [lotServer] installation script [update: Solve the disconnection problem]" on hostloc. I just want to use it. Then, what should I do if ruisu does not support CentOS6.8 or any CentOS6.8 kernel? Downgrade the kernel and install the acute speed!

First, let's take a look at your CentOS version and follow the commands in the log "some common Liunx commands and VPS commands:

cat /etc/issue

We can see that we are actually CentOS6.8

Next, check the kernel version. The command is:

uname -a

We can see that our current kernel is 2.6.32-642.6.2.el6.x86 _ 64.

Compare the list of kernel supported by reexpress, address: https://github.com/0oVicero0/serverSpeeder_kernel/blob/master/SystemList.md

We can see that our kernel is not supported, so what kernel should we downgrade?

Now we need to go to http://ftp.scientificlinux.org/linux/scientific/6.X/XX/updates/security/

This link is used to find the kernel that can match and be compatible with acute speed. In the above address, 6.x represents your system version. XX represents the number of digits in the system. 32-bit is i386, and 64-bit is X86_64.

After reading the 6.8 kernel, the acute speed is not supported, and the 6.7 kernel acute speed is supported, but not there until the 2.6.32-504.3.3.el6.x86 _ 64 kernel of 6.6 Finally matches the acute speed.

So let's change the kernel first and run the following command to download it:

wget http://ftp.scientificlinux.org/linux/scientific/6.6/x86_64/updates/security/kernel-2.6.32-504.3.3.el6.x86_64.rpm

Then execute the installation:

rpm -ivh kernel-2.6.32-504.3.3.el6.x86_64.rpm --force

After the installation is complete, run the command to restart

reboot

After the restart, run the preceding command to check whether the kernel version has been changed.

Then execute the installation script:

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

During installation, You need to press the Enter key to continue. In other cases, you need to choose whether VPN acceleration is enabled, whether Automatic startup is enabled, and whether or not the acute speed is enabled.

After all y is selected, You can see "LotServer is running !" .

At this point, the refresh LotServer script is installed and pressed. The following is the uninstall Command provided by the original author. You can clean and uninstall the Refresh:

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

At the same time, the original author provides the following commands:

/Appex/bin/lotServer. sh start // start command
/Appex/bin/lotServer. sh status // query the status
/Appex/bin/lotServer. sh stop // stop Acceleration

The installation speed of Vultr has reached this point. As for the effect after installation, there are many test reports on the Internet for your reference.

In fact, the focus of this time is not on how to install the sharp speed, but on the previous system for downgrading and replacing the kernel. It is the key to solve the problem by replacing the kernel.
