1. 安装

yum install docker

中间会提示是否确认下载安装：输入y,回车。等出现complete！即可

2. 查看是否安装成功

sudo docker version

启动docker

systemctl start docker # 启动docker
    systemctl restart docker # 重启dokcer

设置docker开机自启

systemctl enable docker

关闭开机自启

systemctl stop docker

4. 重启docker

sudo service docker restart

5. 登录dock

docker login

输入用户名/密码 即可

用户账户注册: [https://hub.docker.com/signup][https_hub.docker.com_signup]

注册过程中序使用邮箱校验,亲测@163.com 可行,

6. 查看docker 中已有的镜像

docker images

7. 使用中用到的命令

//查看容器id
    [root@iZ2zef24sdj1ffusy0wlmqZ local]# docker ps   ///6fe6c195af08
    CONTAINER ID        IMAGE                                                    COMMAND                  CREATED             STATUS                PORTS                                        NAMES
    6fe6c195af08        osixia/openldap                                          "/container/tool/run"    47 hours ago        Up 47 hours           0.0.0.0:389->389/tcp, 0.0.0.0:636->636/tcp   tydicldap
    
    //拷贝文件(将linux的index.html 拷贝到 容器84d6050a80f2 的某一路径下)
    docker cp index.html 84d6050a80f2:/usr/share/nginx/html/index.html
    
    //拷贝文件 (将仓库里的文件拷贝到跟目录)
    docker cp 84d6050a80f2:/usr/share/nginx/html/index.html ./

关于出现docker 版本过低的 解决方案:

\#\#可能出现docker版本问题  
\[root@ harbor\]\# docker -v  
Docker version 1.13.1, build 7f2769b/1.13.1

\[root@ harbor\]\# ./install.sh

\[Step 0\]: checking installation environment ...  
✖ Need to upgrade docker package to 17.06.0+.

\#\#\#\#解决方案\#\#\#\#\#\#

先关闭docker

service docker stop

1. 卸载docker  
\[root@ harbor\]\# yum remove docker                   docker-client                   docker-client-latest                   docker-common                   docker-latest                   docker-latest-logrotate                   docker-logrotate                   docker-selinux                   docker-engine-selinux                   docker-engine

2. 安装新的docker，  
\#\#\#不要使用命令:yum install docker  来安装,该命令只会下载 1.13.1 版本的docker,版本过低

3. 安装yum管理工具：  
\[root@\]\# yum install -y yum-utils

4. 添加国内镜像源  
\[root@ harbor\]\# yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

5. 查看软件版本：  
\[root@ harbor\]\# yum list docker-ce --showduplicates|sort -r

6. 安装指定的docker版本  
\[root@ harbor\]\# yum install docker-ce-17.06.2.ce-1.el7.centos

\#OK 完毕! 启动docker

**8. docker 配置阿里云镜像加速**

参考 :  [https://www.cnblogs.com/LUA123/p/11401962.html][https_www.cnblogs.com_LUA123_p_11401962.html]

访问 [https://help.aliyun.com/document\_detail/60750.html][https_help.aliyun.com_document_detail_60750.html]

[![format_png][]][format_png 1]

点击进入控制台

[![format_png 2][]][format_png 2 1]

前往开通

[![format_png 3][]][format_png 3 1]

设置密码

[![format_png 4][]][format_png 4 1]

确定，进来后，点击**镜像加速器**

[![format_png 5][]][format_png 5 1]

就冒出来配置方法，很简单的，就是拿到加速地址，然后去搞个json文件即可。

vim /etc/docker/daemon.json
    
    # 添加如下内容，具体地址自己申请咯
    {
      "registry-mirrors": ["https://****.mirror.aliyuncs.com"]
    }
    
    # 重启服务
    systemctl daemon-reload
    systemctl restart docker
