参考文档:https://docs.docker.com/engine/installation/linux/docker-ce/centos/#install-docker-ce
简介
docker包括:Community Edition (CE) and Enterprise Edition (EE),本文讲CE版本安装.
环境
CentOS release 6.8 (Final)
安装依赖
yum 开启centos-extras库,默认是开启的.如果被禁用,请参考:https://wiki.centos.org/AdditionalResources/Repositories 开启
安装步骤
1.删除旧版本的docker
如果有旧版本的docer,删除
$ sudo yum remove docker
docker-common
docker-selinux
docker-engine2.安装docker
安装docker有四种方式:
1.yum安装
2.通过tar包安装
3.通过在线脚本安装
2.1 yum安装docker
1.安装必要工具
$ sudo yum install -y yum-utils
device-mapper-persistent-data
lvm22.安装yum资源库文件
$ sudo yum-config-manager
--add-repo
https://download.docker.com/linux/centos/docker-ce.repo3.开启docker-ce-edge资源库
$ sudo yum-config-manager --enable docker-ce-edge4.安装docker
sudo yum install docker-ce或者指定特定docker版本
$ yum list docker-ce --showduplicates | sort -r

Available Packages
$ sudo yum install <FULLY-QUALIFIED-PACKAGE-NAME>这里安装docker最新的stable版本
[root@docker01 ~]# yum install docker-ce-17.09.0.ce

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest当前系统glibc是2.12很旧的版本，需要升级glibc到2.17,而glibc2.17是centos7上用的,鉴于在centos6上安装glibc2.17有风险,不升级glibc.docker官网已经不提供cetnos6的docker下载.
还好在https://pkgs.org/download/docker-io 找到了docker-io(docker centos6安装包)
wget http://dl.fedoraproject.org/pub/epel/testing/6/x86_64//docker-io-1.7.1-4.el6.x86_64.rpm
yum install docker-io-1.7.1-4.el6.x86_64.rpm
Requires: lxc需要安装lxc,但是默认的repo没有lxc安装包
wget https://codeload.github.com/lxc/lxc/zip/stable-1.1
mv stable-1.1 lxc-stable-1.1.zip
unzip lxc-stable-1.1.zip
cd lxc-stable-1.1/
执行检查脚本:
./autogen.sh
+ test -d autom4te.cache
+ libtoolize
./autogen.sh: line 27: libtoolize: command not found
+ exit 1
#装libtool
yum install libtool -y
……
执行检查脚本:
lxc-stable-2.1]# ./autogen.sh
+ test -d autom4te.cache
+ aclocal -I config
+ autoheader
+ autoconf
+ automake --add-missing --copy

#编译安装
./configure
……
configure: error: please install libcap-devel.安装上面需要的包
yum install gnutls
2.2 tar安装
weg https://download.docker.com/linux/centos/7/x86_64/stable/Packages/docker-ce-17.09.0.ce-1.el7.centos.x86_64.rpm
sudo yum install /path/to/package.rpm
sudo systemctl start docker
sudo docker run hello-world2.3 在线脚本
事实证明以上的安装方式都行不通
mmp!

Complete!注意:
最docker-1.10以后彻底放弃了lxc转而使用libcontainer(go).建议安装最新的docker使用centos7.
