The problem found

Recently, I needed to use docker in my work, so I found a few tutorials to install it enthusiastically.


wget -qO- https://get.docker.com/ | sh

then


docker info

Output:


Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

through service docker restart docker attempt did not change, to view the log tail - 5 f/var/log/upstart/docker log found


time="2017-04-23T01:13:59.857654612-04:00" level=fatal msg="Your Linux kernel version 2.6.32-042stab116.2 is not supported for running docker. Please upgrade your kernel to 3.10.0 or newer."

Problem solving

The problem is that the current kernel 2.6 version of linux is too low and needs to be upgraded above 3.10. vps comes with template [face mask] and vps based on OpenZV 6 is 2.6 by default, docker requires 3.x based kernel, only vps based on OpenZV 7 is supported (3.x based kernel).

conclusion
