1. 在/usr/lib/systemd/system/docker.service，配置遠端訪問。

# vim /usr/lib/systemd/system/docker.service
[Service]
ExecStart=
ExecStart=/usr/bin/dockerd -H tcp://0.0.0.0:2375 -H unix://var/run/docker.sock

2. docker重新讀取配置檔案，重新啟動docker服務

# systemctl daemon-reload
# systemctl restart docker

3. 驗證

# ps -ef|grep docker
