## 附上一段安装Docker和docker-compose的脚本(个人编写使用，原谅写的不好)： ##

#!/bin/sh
    if [ "$USER" != "root" ];then
        echo "非管理员，退出执行"
        exit 1
    else
        echo "以下操作将会以管理员身份进行！"
    fi
    
    # 判断 docker 是否可用
    systemctl restart docker
    docker info
    if [ $? -ne 0 ]; then
        # 卸载docker
        yum -y remove docker.x86_64 \
            && yum -y remove docker-client.x86_64  \
            && yum -y remove docker-common.x86_64
        rm -rf /var/lib/docker
        rm -rf /etc/docker
    fi
    
    # 判断 docker 是否已经安装
    if [ `yum list installed | grep docker |wc -l` -eq 0 ];then
    #    没安装
        yum -y install docker-io \
        && systemctl restart docker \
        && systemctl enable docker \
        && sudo mkdir -p /etc/docker
    sudo mkdir -p /etc/docker
    sudo tee /etc/docker/daemon.json <<-'EOF'
    {
      "registry-mirrors": ["http://b8e5adf1.m.daocloud.io","https://azv9dg7g.mirror.aliyuncs.com"]
    }
    EOF
        sudo systemctl daemon-reload
        sudo systemctl restart docker
        echo "   安装docker完成    "
    fi
    
    # 判断wget是否可用
    wget --help
    if [ $? -ne 0 ]; then
    # 不可用
        yum -y install wget
    fi
    
    # 判断 docker-compose 是否可用
    docker-compose version
    if [ $? -ne 0 ]; then
    # 不可用
        rm -rf /usr/local/bin/docker-compose
    fi
    
    if [[ ! -f  "/usr/local/bin/docker-compose" ]] || [[ ! -x  "/usr/local/bin/docker-compose" ]];then
     wget -O /usr/local/bin/docker-compose  https://github.com/docker/compose/releases/download/1.22.0/docker-compose-`uname -s`-`uname -m`	\
        && chmod +x /usr/local/bin/docker-compose
    
        # 判断 docker-compose 是否可用
        docker-compose version
        if [ $? -ne 0 ]; then
    		sleep 3
    		wget -O /usr/local/bin/docker-compose  https://github.com/docker/compose/releases/download/1.22.0/docker-compose-`uname -s`-`uname -m`	\
    			&& chmod +x /usr/local/bin/docker-compose
        # 不可用
           echo -e "请手动安装docker-compose \n"
           echo "wget -O /usr/local/bin/docker-compose  https://github.com/docker/compose/releases/download/1.22.0/docker-compose-`uname -s`-`uname -m` && chmod +x /usr/local/bin/docker-compose"
           exit 1
        fi
    
    	docker-compose version
        if [ $? -ne 0 ]; then
    		# 不可用
           echo -e "请手动安装docker-compose \n"
           echo "wget -O /usr/local/bin/docker-compose  https://github.com/docker/compose/releases/download/1.22.0/docker-compose-`uname -s`-`uname -m` && chmod +x /usr/local/bin/docker-compose"
           exit 1
        fi
    
        systemctl restart docker     \
        && echo "   安装docker-compose完成   "
    fi

### yum卸载、安装 ###

卸载老版本的 docker 及其相关依赖

sudo yum remove docker docker-common container-selinux docker-selinux docker-engine

安装 yum-utils，它提供了 yum-config-manager，可用来管理yum源

sudo yum install -y yum-utils

添加yum源

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

更新yum索引

sudo yum makecache fast

安装 docker-ce

sudo yum install docker-ce
