Docker 1.4.1无法在Fedora 21上启动：FATA
最近我的本地Fedora 21上的docker服务停止工作。 当我尝试运行守护进程使用：
sudo systemctl start docker
它结束于：
Job for docker.service failed. See "systemctl status docker.service" and "journalctl -xe" for details.
通过sudo systemctl status docker检查docker状态

原来没有/var/run/docker.sock套接字，在启动docker服务时无法创build。 如果我尝试运行它：
sudo docker -d
它结束于：

它在几天前工作，docker总是运行的选项：
--selinux-enabled -D -H fd:// -H tcp://0.0.0.0:2376 --bip=172.17.42.1/16 --dns=172.17.42.1 --dns-search=docker
我的问题是 ：什么可能是问题的根源？ Docker在几天前顺利运行。 根据yum.log 2月5日更新了yum.log docker-io的更新yum.log ：
[0] % sudo tail -n 100 /var/log/yum.log | grep dock Feb 05 18:49:42 Updated: docker-io-1.4.1-8.fc21.x86_64

UPDATE
事实certificate，这个问题与docker-1.4.1无关，我已经尝试降级到1.4.0和1.3.2，结果相同。 我检查了我的日志，最后一次确实是在2月4日。 从那时起，几个包被更新了，下面是yum.log的完整列表：

其中一个升级的软件包可能会与docker产生冲突。 我也尝试切换到几个不同的内核版本，例如3.18.5-201.fc21.x86_64，3.18.3-201.fc21.x86_64和3.17.8-300.fc21.x86_64，但结果是一样的。
我被要求发布解决scheme作为答案，所以在这里。
解
好的，我发现问题是什么 – 当然是/etc/sysconfig/docker的dockerconfiguration。 我采取的步骤找出来：
- 首先，我将
/var/lib/docker/重命名为允许docker重新创build其文件结构（我决定在阅读https://bugzilla.redhat.com/show_bug.cgi?id=1099375后试用） – 这有助于sudo systemctl docker start运行没有错误， - 但之前我这样做，我重新安装docker，所以我以前的docker设置丢失 – 我添加了他们，并重新启动：它失败了，
- 我不得不删除
-H fd:// -H tcp://0.0.0.0:2376，这似乎是boot2docker所需的一些设置（我的同伴在MacOS和Windows上使用b2d）， - 我还被要求添加
-s overlay来运行选项。
它解决了这个问题。 它也适用于以前的/var/lib/docker/目录（至less我不必再次下载所有的容器）。
@marekgoldmann也指出了我的问题 – https://bugzilla.redhat.com/show_bug.cgi?id=1186669#c2 ，尤其是它的bugzilla的解释。 谢谢Marek对你的帮助！ 🙂
我希望这篇文章可以帮助你，如果你遇到与docker相似的问题。
