卸载安装docker

一、卸载

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

二、下载离线安装包

https://download.docker.com/linux/static/stable/x86_64/
解压文件并且复制

tar -xvf docker-xxxx-ce.tgz /
cp docker/* /usr/bin/

将docker注册为服务

vim /etc/systemd/system/docker.service

启动docker

chmod +x /etc/systemd/system/docker.service #添加文件权限并启动docker
 
systemctl daemon-reload                 #重新加载配置文件
systemctl start docker          #启动Docker
systemctl enable docker.service         #设置开机自启yum

docker 导出镜像

docker save -o /home/rabbitmq-management-3.8.9.tar rabbitmq:management
