Question

所以我在RHEL 7上安装了docker引擎

现在我做了

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＆＃34; systemctl status docker.service＆＃34;和＆＃34; journalctl -xe＆＃34; 我明白了：

docker.service - Docker Application Container Engine

我试图为此搜索解决方案但找不到任何。

Answer 1

解决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，对我来说这很有效：

在daemon.json

/etc/docker/

把它放进去：

{
"exec-root": "/path/to/docker/run",
"storage-driver": "overlay",
"graph": "/path/to/docker/lib"
}
然后尝试：docker daemon
重新启动
docker run hello-world现在应该成功

Answer 2

检查/var/log/syslog文件中是否有警告或错误消息。
可能是您在docker的配置文件中犯了一个错误，当服务启动时它会出错。

Answer 3

您使用的是什么版本的Docker？如果您未与年长者保持联系，请考虑使用最新版本（目前为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

还尝试在没有-D的情况下以调试模式（systemd）启动Docker，就像它是一个通用程序一样。这将有助于找出守护进程无法启动的原因。

Answer 4

只需删除Docker Lib并使用以下命令再次重新启动它即可：

sudo rm -rf  /var/lib/docker

然后

sudo systemctl enable docker
sudo systemctl start docker

Answer 5

泊坞窗服务无法运行的原因很多。我遇到的其中之一是对json文件中的键值对使用单引号而不是双引号。

失败

sudo cat > /etc/docker/daemon.json << '_EOF'
{
    'registry-mirrors': ['https://docker.io'] 
}
_EOF

有效！

sudo cat > /etc/docker/daemon.json << '_EOF'
{
    "registry-mirrors": ["https://docker.io"] 
}
_EOF
