Docker 和 Docker-Compose 安装

1. Docker 二进制脚本安装

docker_download_link="https://download.docker.com/linux/static/stable/x86_64/"
docker_service="/usr/lib/systemd/system/docker.service"
registry_mirrors="https://7hsct51i.mirror.aliyuncs.com"
docker_dir_base="/opt/docker"
docker_dir_bin="${docker_dir_base}/bin"
docker_dir_conf="${docker_dir_base}/conf"
docker_dir_data="${docker_dir_base}/data"
 
# 如下自动执行
mkdir -p ${docker_dir_bin}
mkdir -p ${docker_dir_conf}
mkdir -p ${docker_dir_data}
# 安装wget
rpm -q wget > /dev/null 2>&1
if [ "$?" -ge 1 ];then
    echo "install wget,Please wait..."
    yum -y install wget > /dev/null 2>&1
    rpm -q wget > /dev/null 2>&1
    [ $? -ge 1 ] && echo "wget installation failure,exit" && exit
     echo "安装wget 成功"
fi
# 下载软件包并解压
if [ ! -f ${docker_software}.tgz ];then
	echo "正在下载安装包：${docker_software}.tgz"
    wget ${docker_download_link}${docker_software}.tgz
    [ ! -f ${docker_software}.tgz ] && echo "${docker_software}.tgz download failure,exit" && exit
else
	echo "安装包已存在：${docker_software}.tgz"
fi
mkdir -p ${docker_dir_bin}
tar zxvf ${docker_software}.tgz -C ${docker_dir_base} > /dev/null 2>&1
if [ "$?" != 0 ];then
	echo "${docker_software}.tgz 解压失败，退出程序" && exit
fi
mv -f ${docker_dir_base}/docker/* ${docker_dir_bin} > /dev/null 2>&1
find ${docker_dir_bin} -type f | xargs -i ln -sfn {} /usr/local/bin/

2. Docker-Compose 二进制脚本安装

#!/bin/bash
docker_compose='docker-compose'
# 下载软件包并解压
if [ ! -f ${docker_compose}* ];then
	echo "正在下载安装包：${docker_compose}"
    curl -L https://github.com/docker/compose/releases/download/1.29.2/docker-compose-Linux-x86_64 -o ./${docker_compose}
    [ ! -f ${docker_compose}* ] && echo "${docker_compose} download failure,exit" && exit
else
	echo "安装包已存在：${docker_compose}"
fi
chmod 777 ${docker_compose}
mv -f ${docker_compose} /usr/local/bin
${docker_compose}
if [ "$?" -eq 0 ];then
	clear && echo "安装${docker_compose}成功"
fi
docker-compose
