Reinstall Any OpenVZ/LXC VPS to Debian/CentOS/Alpine
wget -qO OsMutation.sh https://raw.githubusercontent.com/LloydAsp/OsMutation/main/OsMutation.sh && chmod u+x OsMutation.sh && ./OsMutation.sh
or
curl -so OsMutation.sh https://raw.githubusercontent.com/LloydAsp/OsMutation/main/OsMutation.sh && chmod u+x OsMutation.sh && ./OsMutation.sh
for vps whose disk is small (less than 1GiB, experimental support)
wget -qO OsMutation.sh https://raw.githubusercontent.com/LloydAsp/OsMutation/main/OsMutationTight.sh && chmod u+x OsMutation.sh && ./OsMutation.sh
Openvz and Lxc are typical container virtualization technologys. The host OS kernel is shared with both the host and other containers, and all the applications and runtime libraries required by os are packed together in container itself.
So if you want to replace the operating system, you can just replace the files in the container. That's it, simple and straightforward. Just pay attention to the order of action since there are some dependences of files.
LXC templates are directly downloaded from http://images.linuxcontainers.org, OpenVZ 7 templates are extracted from OpenVZ 7 official iso.
