# 安装准备： #

*  系统CentOS7版本及其以上
 *  内核版本3.10版本及其以上
 *  掌握基本的Linux命令
 *  `查看系统内核：uname -r`
 *  `查看系统配置：cat /etc/os-release`

# 安装： #

### 1. 要卸载之前版本(从来没安装过忽略) ###

yum remove docker \
                      docker-client \
                      docker-client-latest \
                      docker-common \
                      docker-latest \
                      docker-latest-logrotate \
                      docker-logrotate \
                      docker-engine

### 2.安装更新必要文件 ###

yum install -y yum-utils
    yun makecache fast

### 3.设置镜像仓库 ###

但此仓库是国外的不稳定

yum-config-manager \
        --add-repo \
        https://download.docker.com/linux/centos/docker-ce.repo

建议设置阿里云镜像：

yum-config-manager \
        --add-repo \
        http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

1.
    sudo mkdir -p /etc/docker
    2.
    sudo tee /etc/docker/daemon.json <<-'EOF'
    { 
      "registry-mirrors": ["https://hwojgfjj.mirror.aliyuncs.com"]
    }
    EOF
    3.
    sudo systemctl daemon-reload
    4.
    sudo systemctl restart docker

***运行完上面四步骤就加速成功了***

### 4.安装 ###

docker-ce 社区版 docker-ee 企业版（默认最新版本）

yum install docker-ce docker-ce-cli containerd.io

### 5.启动 ###

systemctl start docker

### 6.测试是否安装成功 ###

docker version

### 7.hello-world ###

docker run hello-world

出现红箭头指向的话，说明docker 安装成功了
