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

docker官方离线包下载地址

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
