RES='\E[0m'

function install_docker_system
{
        if ! which docker;then
                echo -e "${RED}[+]No docker command, Begin install docker...${RES}"
        #cd ./deploy
                tar -zxvf $DOCKER_FILE
                cp docker/* /usr/bin/
        fi

        if [ ! -f "$SYSTEMD_PATH" ];then
                >$SYSTEMD_PATH cat <<EOF

                chmod +x $SYSTEMD_PATH
                systemctl daemon-reload
                systemctl restart docker
                systemctl enable docker
                sleep 3s
        fi


        docker ps > /dev/null 2>&1
        if [ $? -eq 0 ];then
                echo -e "${GREEN}[+]Docker install successed!${RES}"
        fi

        if ! which docker-compose;then
                echo -e "${RED}[+]No docker-compose command，Begin install docker-compose...${RES}"
                rpm -ivh $DOCKER_COMPOSE_FILE
                ( echo '#!/bin/bash'; echo 'docker compose $@' ) > /bin/docker-compose
                chmod 755 /bin/docker-compose
        fi

        which docker-compose
        if [ $? -eq 0 ];then
                echo -e "${GREEN}[+]Docker-compose install successed!${RES}"
        fi
}
function uninstall_docker_system
{
        echo "Stop docker systemd..."
        systemctl stop docker
        for i in `ls docker`;do rm -v /usr/bin/"$i";done
        rm -v $SYSTEMD_PATH
        echo -e  "${GREEN}[+]Uninstall docker complete!${RES}"
        for w in `rpm -qa | grep docker-compose`;do rpm -e --nodeps $w;done
        rm -v /usr/bin/docker-compose
        echo -e  "${GREEN}[+]Uninstall docker-compose complete!${RES}"
}
case "$1" in
        install)
        install_docker_system
        ;;
        uninstall)
        uninstall_docker_system
esac
exit 0

其中往docker.service写systemd管理的内容也可以替换成如下内容：

        if [ ! -f "$SYSTEMD_PATH" ];then
                echo """
[Unit]
Description=Docker service
Requires=network.target
After=network.target

[Service]
Type=simple
ExecStart=/usr/bin/dockerd

PIDfile=/var/run/docker.pid
Restart=always

[Install]
WantedBy=basic.target
                 """ > $SYSTEMD_PATH

运行结果：
