1.安装阶段

直接使用yum命令安装

1）先清理系统，保证系统是干净的：

[root@localhost ~]# yum remove docker  docker-common docker-selinux docker-engine

2）安装依赖、更新源、安装docker

[root@localhost ~]# yum install -y yum-utils device-mapper-persistent-data lvm2
    更新完毕:
      device-mapper-libs.x86_64 7:1.02.146-4.el7                                                                                       
    
    作为依赖被升级:
      device-mapper.x86_64 7:1.02.146-4.el7                              device-mapper-event.x86_64 7:1.02.146-4.el7                  
      device-mapper-event-libs.x86_64 7:1.02.146-4.el7                   lvm2.x86_64 7:2.02.177-4.el7                                 
      lvm2-libs.x86_64 7:2.02.177-4.el7                                 
    
    完毕！
    [root@localhost ~]# yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
    [root@localhost ~]# yum list docker-ce --showduplicates | sort -r
    [root@localhost ~]# yum install docker*
    已安装:
      docker.x86_64 2:1.13.1-75.git8633870.el7.centos                                                                                  
    
    作为依赖被安装:
      docker-client.x86_64 2:1.13.1-75.git8633870.el7.centos           docker-common.x86_64 2:1.13.1-75.git8633870.el7.centos          
    
    完毕！

3）查看安装情况，出现版本信息，说明安装成功

[root@localhost ~]# docker --version
    Docker version 1.13.1, build 8633870/1.13.1

2.docker配置

1）关闭防火墙

[root@localhost ~]# systemctl stop firewalld.service
    [root@localhost ~]# systemctl disable firewalld.service

2）关闭SELINUX

[root@localhost ~]# vi /etc/sysconfig/selinux 
    #设置
    SELINUX=disabled
    [root@localhost ~]# setenforce 0

3）修改docker配置文件

[root@localhost ~]#vim /etc/sysconfig/docker
    
    # /etc/sysconfig/docker
    
    # Modify these options if you want to change the way the docker daemon runs
    OPTIONS='--selinux-enabled=false --log-driver=journald --signature-verification=false'
    if [ -z "${DOCKER_CERT_PATH}" ]; then
        DOCKER_CERT_PATH=/etc/docker
    fi

4.启动docker，查看信息

[root@localhost ~]# systemctl daemon-reload
    [root@localhost ~]# service docker restart
    [root@localhost ~]# docker info
