The error is as follows:

/usr/bin/docker-current: Cannot connect to the Docker daemon at tcp://localhost:2375. Is the docker daemon running?.

See '/usr/bin/docker-current run --help'.

Solution:

Go to/lib/systemd/system/docker.service

Part of the original document:

ExecStart=/fsr/bin/dockerd-current \

--add-runtime docker-runc=/usr/libexec/docker/docker-runc-current \

--default-runtime=docker-runc \

--exec-opt native.cgroupdriver=systemd \

--userland-proxy-path=/usr/libexec/docker/docker-proxy-current \

--init-path=/usr/libexec/docker/docker-init-current \

--seccomp-profile=/etc/docker/seccomp.json \

$OPTIONS \

$DOCKER_STORAGE_OPTIONS \

$DOCKER_NETWORK_OPTIONS \

$ADD_REGISTRY \

$BLOCK_REGISTRY \

$REGISTRIES

This section is completely annotated and rewritten as follows:

ExecStart=/usr/bin/dockerd -H tcp://0.0.0.0:2375 -H unix:///var/run/docker.sock -H tcp://0.0.0.0:7654

Other parameters unchanged, restart docker

systemctl daemon-reload

systemctl restart docker.service

After completion, check whether the startup is normal and you can see the version information
