今日在centos安装docker步骤如下：

1.配置yum源

 tee docker.repo<<EOF
> [docker-main-repo]
> name=Docker main Repository
> baseurl=http://mirrors.aliyun.com/docker-engine/yum/repo/main/centos/6
> enabled=1
> gpgcheck=1
> gpgkey=http://mirrors.aliyun.com/docker-engine/yum/gpg
> EOF

2.安装dcoker

yum -y install docker-io

3.启动docker

/etc/init.d/docker start

4.查看docker进程

ps -ef| grep docker

发现进程并没有。。。

5.查看日志

vim /var/log/docker

/nTue Mar 21 17:16:50 CST 2017/n

发现是libdevmapper.so.1.02模块的问题，于是安装该模块所在的包

 

yum upgrade device-mapper-libs

然后再启动docker

/etc/init.d/docker start

查看进程

root     23195     1  4 17:25 pts/2    00:00:00 /usr/bin/docker -d
已经在了

但是

默认的源可能会导致相关的镜像无法下载，这个问题修改本地的docker源就可以了具体如下

编辑docker配置文件

other_args=" --registry-mirror=https://jxus37ad.mirror.aliyuncs.com"

保存并重启docker

OK了
