1.1 用脚本离线安装

1.1.1 上传docker-18.06.3-ce.tgz至服务器

#安装包docker-18.06.3-ce.tgz下载地址
https://download.docker.com/linux/static/stable/x86_64/

1.1.2 创建一键安装脚本：touch install.sh

#!/bin/sh

echo '解压tar包'
tar -xvf docker-18.06.3-ce.tgz
echo '将docker目录下所有文件复制到/usr/bin目录'
cp docker/* /usr/bin
echo '将docker.service 复制到/etc/systemd/system/目录'
cp docker.service /etc/systemd/system/
echo '添加文件可执行权限'
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

1.1.3 创建docker系统服务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
ExecStart=/usr/bin/dockerd
ExecReload=/bin/kill -s HUP $MAINPID
TimeoutSec=0
RestartSec=2
Restart=always

[Install]
WantedBy=default.target

1.1.4 运行安装脚本安装

#授权文件为可执行
chmod +x install.sh
chmod +x docker.service
#运行安装脚本
sh install.sh
#查看docker安装版本
docker version

1.2 用脚本离线卸载

1.2.1编写一键卸载脚本touch uninstall.sh

#!/bin/sh
echo '停止docker'
systemctl stop docker
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'

1.2.2 运行卸载脚本卸载

#授权文件为可执行
chmod +x uninstall.sh
#运行卸载脚本
sh uninstall.sh
