docker - 在centos 7上安装本地docker注册表

Question

我正在尝试在CentOS 7上安装本地docker.io注册表
按照以下说明操作机器:

https://github.com/docker/docker-registry#quick-start

我跑了(编辑，只是为了显示docker正在运行):

# service docker restart && cd && docker run -p 5000:5000 registry

在看了几分钟的提示后，我遇到了很多这样的错误:

[...]

编辑:

系统细节:

docker --version
Docker version 1.3.2, build 39fa2fa/1.3.2

系统:

cat /etc/centos-release
CentOS Linux release 7.0.1406 (Core)

uname -a
Linux denis1 3.10.0-123.20.1.el7.x86_64 #1 SMP Thu Jan 29 18:05:33 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

有什么想法我可能做错了吗？

该文件应该在哪里？ './registry._setup_database.lock'
编辑2:

如果我在我的Ubuntu 14.10笔记本电脑上尝试通过ppa安装了新版本的docker，那么它可以工作:

# Upgraded to docker 1.5 via a ppa package in my Ubuntu laptop:

sudo add-apt-repository ppa:docker-maint/testing
sudo apt-get update
sudo apt-get install docker.io

# pull registry latest
sudo docker pull registry:latest

latest: Pulling from registry

有什么想法我该怎么做才能在CentOS服务器上获得相同的结果？
我可以通过 yum install获得CentOS 6的最新docker客户端吗？

Answer 1

禁用SELINUX和FireWalld。

SELINUX阻止执行某些命令(例如SUDO)，这在某种程度上抑制了行为。

还要检查FireWallD。

升级docker版本或“最新”标签等都不能解决您的问题，我尝试了所有方法...与SELINUX和/或FireWallD有关...如果可以，请同时禁用两者。

我通过将其添加到yum.repos.d将Docker版本升级到1.5.0:
