1、删除老版本
停止docker服务
systemctl stop docker
查看当前版本
rpm -qa | grep docker
卸载软件包
yum erase docker \ docker-client \ docker-client-latest \ docker-common \ docker-latest \ docker-latest-logrotate \ docker-logrotate \ docker-selinux \ docker-engine-selinux \ docker-engine \ docker-ce
删除相关配置文件
find /etc/systemd -name '*docker*' -exec rm -f {} \; find /etc/systemd -name '*docker*' -exec rm -f {} \; find /lib/systemd -name '*docker*' -exec rm -f {} \; rm -rf /var/lib/docker #删除以前已有的镜像和容器,非必要 rm -rf /var/run/docker
2、安装新版本
软件包安装
yum install -y yum-utils device-mapper-persistent-data lvm2
添加yum源
yum-config-manager \ --add-repo \ https://download.docker.com/linux/centos/docker-ce.repo
查看可安装的版本
yum list docker-ce --showduplicates | sort -r
安装最新版本
yum install docker-ce -y
启动并开机自启
systemctl start docker systemctl enable docker
查看docker版本
docker version
例子：
