添加 yum 的 repo 文件

本文基于一台空的 RHEL7 的虚拟机进行安装搭建

阿里云的 CentOS7 的 repo 文件

(这里根据 RHEL7 进行了修改)
/etc/yum.repos.d/CentOS-Base.repo

  1. # CentOS-Base.repo
  2. #
  3. # The mirror system uses the connecting IP address of the client and the
  4. # update status of each mirror to pick mirrors that are updated to and
  5. # geographically close to the client.  You should use this for CentOS updates
  6. # unless you are manually picking other mirrors.
  7. #
  8. # If the mirrorlist= does not work for you, as a fall back you can try the 
  9. # remarked out baseurl= line instead.
  10. #
  11. #

阿里云的 docker-ce 的 yum repo 文件

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

安装依赖包

  1. yum install -y http://mirror.centos.org/centos/7/extras/x86_64/Packages/container-selinux-2.119.1-1.c57a6f9.el7.noarch.rpm
  3. yum install -y yum-utils device-mapper-persistent-data lvm2
  5. yum makecache fast
  7. yum -y install docker-ce
  9. service docker start

安装 docker-compose

  1. curl -L https://get.daocloud.io/docker/compose/releases/download/1.27.4/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose
  2. chmod +x /usr/local/bin/docker-compose

把安装包离线化

把上述步骤，在线环境使用 yum -y —downloadonly 进行离线化

  1. # 可以考虑创建个临时用户
  2. # adduser tempuser
  3. mkdir -p /home/tempuser/yumpackages
  4. cd /home/tempuser/yumpackages
  6. wget http://mirror.centos.org/centos/7/extras/x86_64/Packages/container-selinux-2.119.1-1.c57a6f9.el7.noarch.rpm
  8. yum install -y --downloadonly --downloaddir=/home/tempuser/yumpackages http://mirror.centos.org/centos/7/extras/x86_64/Packages/container-selinux-2.119.1-1.c57a6f9.el7.noarch.rpm
  10. yum install -y --downloadonly --downloaddir=/home/tempuser/yumpackages yum-utils device-mapper-persistent-data lvm2
  12. yum install -y --downloadonly --downloaddir=/home/tempuser/yumpackages docker-ce
  14. # 在离线环境，安装某个目录底下的 rpm 包
  15. rpm -ivh *.rpm --nodeps --force
