centos7离线安装docker-ce-17.12.0.ce-1.el7.centos.x86_64.,并实现镜像的导入导出以及启动(以mysql安装为例子)
最近正在学习docker,工作要求离线环境下搭建相关安装相关环境,docker成了最好的选择
centosdocker以及相关依赖下载
将下载文件导入对应centos系统的目录本人使用/root/docker
执行
cd /root/docker
禁止依赖检查强制安装
rpm -ivh *.rpm --nodeps --force
安装完成之后输入docker -v查看docker版本输出如下则安装完成
Docker version 17.05.0-ce, build 89658be
此处以mysql安装为例
在一台能够联网的机器上安装docker并执行
docker pull registry.cn-hangzhou.aliyuncs.com/acs-sample/mysql:5.7
输出如下
5.7: Pulling from acs-sample/mysql

docker rmi registry.cn-hangzhou.aliyuncs.com/acs-sample/mysql
删除无用镜像
由于真正要安装的机器是离线的所以需要镜像导出
docker save mysql:5.7 > /root/mysql5.7.tar
将root目录下的文件拷贝到要安装的操作系统的/root目录下并执行
docker load < /root/mysql5.7.tar
查看镜像是否导入
docker images
若镜像导入成功后启动mysql依次执行
docker create -it mysql:5.7
docker run --name mysqlserver --restart=always -e MYSQL_ROOT_PASSWORD=sgcc -d -i -p 3306:3306 mysql:5.7
注:以上命令中 --restart=always 代表容器机器重启后自动启动容器若启动时没有添加可调用docker update --restart=always xxx (xxx为容器CONTAINET ID可通过 docker ps -a 查看)

可进入终端查看mysql是否安装成功
