安装前提条件:
CentOS 版本 7.x,本例中使用CentOS 7.4
1.安装yum-utils (yum-utils提供yum-config-manager工具包等)
# yum install -y yum-utils \ device-mapper-persistent-data \ lvm2
2.添加docker yum源
# yum-config-manager \
--add-repo \
https://download.docker.com/linux/centos/docker-ce.repo
3.列出历史可安装版本的docker
[root@test yum.repos.d]# yum list docker-ce --showduplicates | sort -r * updates: mirrors.tuna.tsinghua.edu.cn Loaded plugins: fastestmirror Installed Packages * extras: mirrors.tuna.tsinghua.edu.cn * epel: mirrors.tuna.tsinghua.edu.cn docker-ce.x86_64 18.03.0.ce-1.el7.centos docker-ce-stable docker-ce.x86_64 17.12.1.ce-1.el7.centos docker-ce-stable docker-ce.x86_64 17.12.0.ce-1.el7.centos docker-ce-stable docker-ce.x86_64 17.09.1.ce-1.el7.centos docker-ce-stable docker-ce.x86_64 17.09.0.ce-1.el7.centos docker-ce-stable docker-ce.x86_64 17.09.0.ce-1.el7.centos @docker-ce-stable docker-ce.x86_64 17.06.2.ce-1.el7.centos docker-ce-stable docker-ce.x86_64 17.06.1.ce-1.el7.centos docker-ce-stable docker-ce.x86_64 17.06.0.ce-1.el7.centos docker-ce-stable docker-ce.x86_64 17.03.2.ce-1.el7.centos docker-ce-stable docker-ce.x86_64 17.03.1.ce-1.el7.centos docker-ce-stable docker-ce.x86_64 17.03.0.ce-1.el7.centos docker-ce-stable Determining fastest mirrors * base: mirrors.tuna.tsinghua.edu.cn Available Packages
4.安装指定版本的docker
[root@test yum.repos.d]# yum install docker-ce-17.09.0.ce-1.el7.centos
5.启动docker服务
#systemctl start docker
#systemctl status docker --查看docker运行状态
