### **linux篇(debian系)** **安装流程：** 1、进入命令行界面 2、切换至root用户界面 `$ sudo su root` 3、清除旧的仓库 ~~~ $ apt-get purge lxc-docker* $ apt-get purge docker.io* ~~~ 4、添加一个新的gpg钥匙 `$ apt-key adv --keyserver hkp://pgp.mit.edu:80 --recv-keys 58118E89F3A912897C070ADBF76221572C52609D` 5、根据debian的不同版本创建文件(下面以debian-jessie为例) `$ echo 'deb https://apt.dockerproject.org/repo debian-jessie main' > /etc/aptsources.list.d/docker.list` 如果不知道自己的系统版本，输入以下命令：**uname -r** ~~~ # Debian Wheezy deb https://apt.dockerproject.org/repo debian-wheezy main # Debian Jessie deb https://apt.dockerproject.org/repo debian-jessie main # Debian Stretch/Sid deb https://apt.dockerproject.org/repo debian-stretch main # Ubuntu Precise deb https://apt.dockerproject.org/repo ubuntu-precise main # Ubuntu Trusty deb https://apt.dockerproject.org/repo ubuntu-trusty main # Ubuntu Vivid deb https://apt.dockerproject.org/repo ubuntu-vivid main # Ubuntu Wily deb https://apt.dockerproject.org/repo ubuntu-wily main ~~~ 6、更新apt包索引 `$ apt-get update` 7、验证apt是否从正确的仓库下载 `$ apt-cache policy docker-engine` 8、安装docker `$ apt-get install docker-engine` 9、开启docker守护进程 `$ service docker start` 10、验证docker是否正常运行 `$ docker run hello-world` **非root用户使用docker** 1、如果docker用户群不存在，增加docker用户群 `$ sudo groupadd docker` 2、将对应用户添加到docker用户群 `$ sudo gpasswd -a ${USER} docker` 3、重启docker守护进程 `$ sudo service docker restart` **更新docker** `$ apt-get upgrade docker-engine` **卸载docker** 1、删除docker包 `$ sudo apt-get purge docker-engine` 2、删除docker包及不再需要的依赖包 `$ sudo apt-get autoremove --purge docker-engine` 3、删除docker镜像、容器、卷 `$ rm -rf /var/lib/docker`
