docker.service的作业失败，因为控制进程退出并显示错误代码
所以我在RHEL 7上安装了docker引擎
现在当我做了
service docker start 我得到以下错误：
Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xe" for details.
当我去“systemctl status docker.service”和“journalctl -xe”时，我得到：

我试图寻找这个解决scheme，但找不到任何。
你使用什么版本的Docker？ 如果你没有locking老年人，可以考虑使用最新的版本（目前是1.12 ）。 这是我的启动选项（Debian 8，/ /etc/systemd/system/docker.service ）：
[Unit] Description=Docker Application Container Engine Documentation=https://docs.docker.com After=network.target docker.socket Requires=docker.socket [Service] Type=notify ExecStart=/usr/bin/docker daemon -H fd:// --dns=10.240.116.7 --dns 8.8.8.8 --bip=172.17.42.1/24 MountFlags=slave LimitNOFILE=1048576 LimitNPROC=1048576 LimitCORE=infinity TimeoutStartSec=0 [Install] WantedBy=multi-user.target
也可以尝试在没有systemd情况下以debugging模式（ -D ）启动Docker，就像它是一个普通的程序一样。 这将有助于找出守护进程不启动的原因。

See "systemctl status docker.service" and "journalctl -xe" for details. Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xe" for details. 问题，对我来说这工作：
- 在
/etc/docker/daemon.json中创builddaemon.json/etc/docker/ -
把它放在里面：
{
"exec-root": "/path/to/docker/run",
"storage-driver": "overlay",
"graph": "/path/to/docker/lib"
} - 然后尝试：
docker daemon - 重启
-
docker run hello-world应该现在成功
