Linux 离线安装docker的过程（一键式安装）

前言

有时候会遇到服务器不能联网的情况，这样就没法用yum安装软件，docker也是如此，针对这种情况，总结了一下离线安装docker的步骤，分享给大家

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版本

2. 准备docker.service 系统配置文件

									docker.service

									[unit]

									description=docker application container engine

									documentation=https://docs.docker.com

									after=network-online.target firewalld.service

									wants=network-online.target

									[service]

									type=notify

									# the default is not to use systemd for cgroups because the delegate issues still

									# exists and systemd currently does not support the cgroup feature set required

									# for containers run by docker

									execstart=/usr/bin/dockerd

									execreload=/bin/kill -s hup $mainpid

									# having non-zero limit*s causes performance problems due to accounting overhead

									# in the kernel. we recommend using cgroups to do container-local accounting.

									limitnofile=infinity

									limitnproc=infinity

									limitcore=infinity

									# uncomment tasksmax if your systemd version supports it.

									# only systemd 226 and above support this version.

									#tasksmax=infinity

									timeoutstartsec=0

									# set delegate yes so that systemd does not reset the cgroups of docker containers

									delegate=yes

									# kill only the docker process, not all processes in the cgroup

									killmode=process

									# restart the docker process if it exits prematurely

									restart=on-failure

									startlimitburst=3

									startlimitinterval=60s

									[install]

									wantedby=multi-user.target

3. 准备安装脚本和卸载脚本

安装脚本 install.sh

									#!/bin/sh

									echo '解压tar包...'

									tar -xvf $1

									echo '将docker目录移到/usr/bin目录下...'

									cp docker/* /usr/bin/

									echo '将docker.service 移到/etc/systemd/system/ 目录...'

									cp docker.service /etc/systemd/system/

									echo '添加文件权限...'

									chmod +x /etc/systemd/system/docker.service

									echo '重新加载配置文件...'

									systemctl daemon-reload

									echo '启动docker...'

									systemctl start docker

									echo '设置开机自启...'

									systemctl enable docker.service

									echo 'docker安装成功...'

									docker -v

卸载脚本 uninstall.sh

									#!/bin/sh

									echo '删除docker.service...'

									rm -f /etc/systemd/system/docker.service

									echo '删除docker文件...'

									rm -rf /usr/bin/docker*

									echo '重新加载配置文件'

									systemctl daemon-reload

									echo '卸载成功...'
