安装docker以及问题解决办法
1.使用官方推荐的方式安装 yum-utils
yum install -y yum-utils
2.使用如下的命令设置稳定版的 repository
yum-config-manager \
--add-repo \
https://docs.docker.com/engine/installation/linux/repo_files/centos/docker.repo
出现错误Loaded plugins: fastestmirror, refresh-packagekit
更改文件:
1.vim /etc/yum/pluginconf.d/fastestmirror.conf
enabled=0
2. vim /etc/yum.conf
plugins=0
更新yum
yum makecache fast
3.创建文件
vim /etc/yum.repos.d/docker.repo
输入以下内容
[dockerrepo]
name=Docker Repository
baseurl=https://yum.dockerproject.org/repo/main/centos/$releasever/
enabled=1
gpgcheck=1
gpgkey=https://yum.dockerproject.org/gpg
4.安装最新版本的docker
yum -y install docker-engine
5.启动docker
service docker start
6.使用docker
docker run hello-world
可以使用service docker status查看状态
发现错误
Cannot connect to the Docker daemon at 。。。
查看进程出现
docker dead but pid file exists
删除/var/run 下面的docker.xx文件均没用
使用以下方法:
yum-config-manager --enable public_ol6_latest
yum install device-mapper-event-libs

Hello from Docker!
This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps:
1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
(amd64)
3. The Docker daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
to your terminal.
To try something more ambitious, you can run an Ubuntu container with:
$ docker run -it ubuntu bash
