  • Docker进阶之四:centos7安装docker

                      centos7.6 安装docker

    参考:https://docs.docker.com/install/linux/docker-ce/centos/

    一.存在老版本先删除

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

    二.(安装依赖)Install required packages. yum-utils provides the yum-config-manager utility, and device-mapper-persistent-data and lvm2 are required by the devicemapper storage driver.

      $ yum install -y yum-utils device-mapper-persistent-data lvm2

    三.(配置官方源)Use the following command to set up the stable repository.

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

    四.更新yum包索引
       yum makecache fast
    五.安装Docker CE
       yum install docker-ce -y
    六.启动
       systemctl start docker
    七.卸载
       yum -y remove docker-ce
       rm -rf /var/lib/docker
    八.安装结果验证  docker info

      

      官方测试:sudo docker run hello-world

      

      配置文件: /etc/sysconfig/docker

      存储位置: /var/lib/docker

    九. 配置Docker加速器

      curl -sSL https://get.daocloud.io/daotools/set_mirror.sh | sh -s http://f1361db2.m.daocloud.io

      sudo systemctl restart docker

    十. 备注:错误汇总

      1.配置官方源报错

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

        错误信息如下:

        Timeout on https://download.docker.com/linux/centos/docker-ce.repo: (28, 'Operation timed out after 30034 milliseconds with 0 out of 0 bytes received')

        错误原因:由于国内访问不到docker官方镜像的缘故

        解决方法:修改国内阿里云地址即可

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

     2.内核版本过低报错

      docker: Error response from daemon: OCI runtime create failed: container_linux.go:344: starting container process caused "process_linux.go:293: copying bootstrap data to pipe caused "write init-p: broken pipe"": unknown.
