1. 準備docker離線包
docker官方離線包下載下傳位址
下載下傳需要安裝的docker版本，我此次下載下傳的是：docker-17.03.2-ce.tgz
2. 準備docker.service 系統配置檔案
建立docker.service
# vim docker.service 内容如下：
[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. 準備安裝腳本和解除安裝腳本
建立安裝腳本：install.sh
# vim install.sh #!/bin/sh
echo '解壓tar包...'
tar -xvf $1
echo '将docker目錄移到/usr/bin目錄下...'
cp docker/* /usr/bin/
echo '将docker.service 移到/etc/systemd/system/ 目錄...'
cp docker.service /etc/systemd/system/
echo '添加檔案權限...'
chmod +x /etc/systemd/system/docker.service
echo '重新加載配置檔案...'
systemctl daemon-reload
echo '啟動docker...'
systemctl start docker
echo '設定開機自啟...'
systemctl enable docker.service
echo 'docker安裝成功...'
docker -v 4. 解除安裝docker腳本
建立解除安裝腳本：delete.sh
$ vim delete.sh #!/bin/sh
echo '删除docker.service...'
rm -rf /etc/systemd/system/docker.service
echo '删除docker檔案...'
rm -rf /usr/bin/docker*
echo '重新加載配置檔案'
systemctl daemon-reload
echo '解除安裝成功...' 5. 安裝docker
5.1 目前目錄下的所有檔案：（藍色的docker是已經安裝完成的檔案夾）
5.2 執行腳本進行安裝
$ bash install.sh docker.tgz 執行過程如下：
待腳本執行完畢後，執行
//檢視docker版本指令
$ docker -v 發現此時docker已安裝成功，可以用
//檢視docker所有指令
$ docker --help 從現在開始你就可以自己安裝image和生成container了
