1. 准备docker离线包
下载需要安装的docker版本，我此次下载的是：docker-17.03.2-ce.tgz
2. 准备docker.service 系统配置文件
创建docker.service
# vim docker.service
内容如下：
1docker.service 2 3[Unit] 4Description=Docker Application Container Engine 5Documentation=https://docs.docker.com 6After=network-online.target firewalld.service 7Wants=network-online.target 8 9[Service] 10Type=notify 11# the default is not to use systemd for cgroups because the delegate issues still 12# exists and systemd currently does not support the cgroup feature set required 13# for containers run by docker 14ExecStart=/usr/bin/dockerd 15ExecReload=/bin/kill -s HUP $MAINPID 16# Having non-zero Limit*s causes performance problems due to accounting overhead 17# in the kernel. We recommend using cgroups to do container-local accounting. 18LimitNOFILE=infinity 19LimitNPROC=infinity 20LimitCORE=infinity 21# Uncomment TasksMax if your systemd version supports it. 22# Only systemd 226 and above support this version. 23#TasksMax=infinity 24TimeoutStartSec=0 25# set delegate yes so that systemd does not reset the cgroups of docker containers 26Delegate=yes 27# kill only the docker process, not all processes in the cgroup 28KillMode=process 29# restart the docker process if it exits prematurely 30Restart=on-failure 31StartLimitBurst=3 32StartLimitInterval=60s 33 34[Install] 35WantedBy=multi-user.target
3. 准备安装脚本和卸载脚本
创建安装脚本：install.sh
# vim install.sh
内容如下：
1#!/bin/sh 2echo '解压tar包...' 3tar -xvf $1 4echo '将docker目录移到/usr/bin目录下...' 5cp docker/* /usr/bin/ 6echo '将docker.service 移到/etc/systemd/system/ 目录...' 7cp docker.service /etc/systemd/system/ 8echo '添加文件权限...' 9chmod +x /etc/systemd/system/docker.service 10echo '重新加载配置文件...' 11systemctl daemon-reload 12echo '启动docker...' 13systemctl start docker 14echo '设置开机自启...' 15systemctl enable docker.service 16echo 'docker安装成功...' 17docker -v
4. 卸载docker脚本
创建卸载脚本：delete.sh
$ vim delete.sh
内容如下：
1#!/bin/sh 2echo '删除docker.service...' 3rm -f /etc/systemd/system/docker.service 4echo '删除docker文件...' 5rm -rf /usr/bin/docker* 6echo '重新加载配置文件' 7systemctl daemon-reload 8echo '卸载成功...'
5. 安装docker
5.1 当前目录下的所有文件：（蓝色的docker是已经安装完成的文件夹）
5.2 执行脚本进行安装
$ sh install.sh docker.tgz
执行过程如下：
待脚本执行完毕后，执行
1//查看docker版本命令 2$ docker -v
发现此时docker已安装成功，可以用
1//查看docker所有命令 2$ docker --help
从现在开始你就可以自己安装image和container了
5.3 删除docker
执行delete.sh脚本
$ sh uninstall.sh
此时输入
$ docker -v
发现docker已经卸载
