[Solved] Job for docker.service failed because the control process exited with error code. After changing the docker configuration

Solution
（ 1) Change       Cnetos7 managed startup file   ， When the configuration service starts, does the daemon use the    Some profiles

vim /usr/lib/systemd/system/docker.service

[ Service]

ExecStart=/usr/bin/dockerd            # delete  – After H (including)   All content

(2) There is a problem with the configuration of daemon.json
Look carefully. What’s wrong

I didn’t write that before   ，   number

{    # Turn on remote connection
” hosts”: [” tcp://0.0.0.0 :2375″,”unix:///var/run/docker.sock”],

#  Image acceleration (write your own, alicloud, don’t write it)
” registry-mirrors”: [“https://*******.mirror.aliyuncs.com”]

}

systemctl   daemon-reload

systemctl   start   docker
Wait for the startup to succeed,
