vultr debian 8 replaces the kernel and installs Ruisu

Recently, I used vultr’s debian 8 to toss around some things, and found that the default kernel of vultr’s debian 8 is 3.16.0-5, which cannot match the sharp speed. So I thought of replacing the kernel and installing Ruisu. This article is a record of this operation. Updated to add debian 7 replacement records.

It's just that the kernel version selection is different. You can also refer to this article for other Debian operating system replacements. The focus is to find the appropriate kernel version.

The Ruisu version I am using is 0oVicero0. Check that the kernel adapted to debian 8 is 3.16.0-4-amd64, and the kernel adapted to debian 7 is 3.2.0-4-amd64.deb.

Check the suitable version of Ruisu:

https://github.com/0oVicero0/serverSpeeder_kernel/blob/master/serverSpeeder.txt

The default version of vultr is 3.16.0-5-amd64.

Specific steps (operated with root account by default):

debian 8 download 3.16.0.4-deb kernel

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

Debian 7 download 3.2.0-4deb kernel

wget http://security-cdn.debian.org/pool/updates/main/l/linux/linux-image-3.2.0-4-amd64_3.2.96-2_amd64.deb

Debian 8 installs 3.16.0-4 kernel

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

Debian 7 installs 3.2.0-4 kernel

dpkg -i linux-image-3.2.0-4*.deb

Delete the original kernel. Since the version we use is lower than the default version of vultr, the kernel version number must be very specific when deleting. (If you use this method to upgrade the kernel, you can skip this kernel deletion operation and proceed directly to the update-grub operation)

Generally display all kernel versions

dpkg -l|grep linux-image

debian 8 delete kernel

apt-get -y remove linux-image-3.16.0-5-amd64

Debian 7 deletes the original kernel

Note: If your debian7 system has used the apt-get update -y command before operating this article, then you need to run the following command.

apt-get -y remove linux-image-3.2.0-5-amd64

apt-get -y remove linux-image-3.2.0-6-amd64

After the operation is completed, enter reboot to restart. This completes the entire step. There is no need to run the following commands.

For Debian 7 that has not updated the system, delete the original kernel and continue with the following command.

apt-get -y remove linux-image-3.2.0-5-amd64

A picture like this appears during the kernel deletion process, abort kernel removal.

Be careful to choose NO.

Update the grub system boot file and restart the system.

update-grub

Log in to the system again and enter unama -a to see that the replacement is successful.

You can also use this method if you want to change the kernel for other versions. The main point of changing the kernel is to find the correct kernel.

Update the kernel pseudo-one-click command. When using the abort kernel removal diagram, you need to manually switch and select NO.
