一键安装docker及docker-compose

1、创建docker存放相关文件目录，该目录可自己定义。2、添加相关文件，可在网盘提取。其中docker-20.10.9.tgz和docker-compose为安装包，也可根据需要在网上下载，注意docker-compose安装包下载后需要改名为docker-compose。

install.sh文件（一键安装脚本）

echo  '创建docker相关目录'
mkdir -p /etc/docker
cp daemon.json /etc/docker
echo '解压tar包...'
tar -xvf ./docker-20.10.9.tgz
echo '将docker目录移到/usr/bin目录下...'
cp -f ./docker/* /usr/bin
echo '将docker.service 移到/etc/systemd/system/ 目录...'
cp -f ./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
if ! docker -v; then
echo "docker 安装失败..."
exit -1
fi
echo 'docker安装成功...'
#============ make docker-compose ===========
echo '安装docker-compose...'
cp -f ./docker-compose /usr/local/bin/
echo '添加文件执行权限...'
chmod +x /usr/local/bin/docker-compose
if ! docker-compose -v; then
echo "docker-compose 安装失败..."
exit -1
fi
echo 'docker-compose 安装成功...'

uninstall.sh文件（卸载脚本）

echo '删除docker所有容器'
docker stop $(docker ps -a -q)
docker rm $(docker ps -a -q)
echo '删除docker所有镜像'
docker rmi -f $(docker images -q)
echo '删除docker.service...'
rm -rf /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...'

3、执行一键安装脚本：sh install.sh


4、验证：执行docker -v和 docker-compose -v查询版本
