What to do if an error occurs when running docker

What should I do if I get an error when running docker?

Use the command to uninstall the related components that have been installed:

$ sudo yum remove docker \
docker-client \
docker-client-latest \
docker-common \
docker-latest \
docker-latest-logrotate \
docker-logrotate \
docker-selinux \
docker-engine-selinux \
docker-engine

Then use find to search from the root directory to find all files containing docker

find / -name ‘*docker*’

or cd After reaching the root directory, search:

find -name ‘*docker*’

Delete the searched file or directory:

rm -rf .....

Then reinstall docker. Can:

yum install docker-ce -y

Start docker to solve the problem

systemctl start docker

Notes

When deleting files or directories, pay attention to all the paths. Don’t delete it by mistake
