This article will explain in detail how to install and uninstall Docker. The editor thinks it is very practical, so I share it with you for reference. I hope you can get something after reading this article.

Preparatory work

System: centos6.x

Install 1. Close seLinux

Vim / etc/selinux/config

Modified value: SELINUX=disabled

# This file controls the state of SELinux on the system.# SELINUX= can take one of these three values:# enforcing-SELinux security policy is enforced.# permissive-SELinux prints warnings instead of enforcing.# disabled-SELinux is fully disabled.SELINUX=disabled# SELINUXTYPE= type of policy in use. Possible values are:# targeted-Only targeted network daemons are protected.# strict-Full SELinux protection.SELINUXTYPE=targeted

View status: sestatus

If the status is not disabled, restart
