docker.service的作业失败,因为控制进程退出并显示错误代码

Question

所以我在RHEL 7上安装了docker引擎

现在,当我做一个

service docker start

我收到以下错误:

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:

docker.service - Docker Application Container Engine

您使用什么版本的 Docker？如果您没有锁定旧版本，请考虑使用最新版本（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

还可以尝试在-D没有 的情况下以调试模式 ( )启动 Docker systemd，就像它是一个普通程序一样。这将有助于找出守护进程未启动的原因。
