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" systemctl status docker.service"和" journalctl -xe" 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。
答案 0 :(得分:2)
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:
daemon.json
/etc/docker/
把它放进去:
{
"exec-root": "/path/to/docker/run",
"storage-driver": "overlay",
"graph": "/path/to/docker/lib"
}
docker daemon
docker run hello-world
现在应该成功答案 1 :(得分: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。
答案 2 :(得分:1)
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。
答案 3 :(得分:1)
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
答案 4 :(得分:1)
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
