docker-ce离线安装

docker-ce提供了常用的linux发行版的安装方式，但是离线安装很多时候仍然是一个需要，这篇文章介绍了如何在centos上使用离线安装包进行docker-ce版本的安装，此方式适用于大部分docker离线安装包的安装方式。

操作系统：

rhel7系列	内核版本大于3.1的redhat衍生版都可以

安装的需要过程及步骤：

Step 1	下载docker-ce的离线安装包
Step 2	解压出docker目录
Step 3	将docker目录下的内容拷贝到/usr/bin下并设置权限
Step 4	设置docker的systemd设定文件-
Step 5	设定docker的开机启动
Step 6	启动docker
Step 7	确认版本

安装脚本：

安装脚本 https://github.com/liumiaocn/easypack/blob/master/docker/install-docker.sh

安装说明：

下载离线安装包，然后将文件名作为参数传给安装脚本即可：
脚本内容:
https://github.com/liumiaocn/easypack/blob/master/docker/install-docker.sh

脚本具体内容：

#!/bin/sh

usage(){
  echo "Usage: $0 FILE_NAME_DOCKER_CE_TAR_GZ"
  echo "       $0 docker-17.09.0-ce.tgz"
  echo "Get docker-ce binary from: https://download.docker.com/linux/static/stable/x86_64/"
  echo "eg: wget https://download.docker.com/linux/static/stable/x86_64/docker-17.09.0-ce.tgz"
  echo ""
}
SYSTEMDDIR=/usr/lib/systemd/system
SERVICEFILE=docker.service
DOCKERDIR=/usr/bin
DOCKERBIN=docker
SERVICENAME=docker

if [ $# -ne 1 ]; then
  usage
  exit 1
else
  FILETARGZ="$1"
fi

if [ ! -f ${FILETARGZ} ]; then
  echo "Docker binary tgz files does not exist, please check it"
  echo "Get docker-ce binary from: https://download.docker.com/linux/static/stable/x86_64/"
  echo "eg: wget https://download.docker.com/linux/static/stable/x86_64/docker-17.09.0-ce.tgz"
  exit 1
fi

echo "##unzip : tar xvpf ${FILETARGZ}"
tar xvpf ${FILETARGZ}
echo

echo "##binary : ${DOCKERBIN} copy to ${DOCKERDIR}"
cp -p ${DOCKERBIN}/* ${DOCKERDIR} >/dev/null 2>&1
which ${DOCKERBIN}

echo "##systemd service: ${SERVICEFILE}"
echo "##docker.service: create docker systemd file"
cat >${SYSTEMDDIR}/${SERVICEFILE} <

创建脚本文件并下载docker-ce离线包并案场安装：
