前言

使用 vagrant 的前提是要有 box 镜像盒子来初始化系统，网上有很多 box 可以下载，但是用自己的不是更香吗？自己动手，丰衣足食！

环境准备

软件准备

首先需要安装 vagrant + virtualbox + packer ，具体安装教程，请参考文章：☀️ 福利向：⚡️万字图文⚡️ 带你 Vagrant 从入门到超神！❤️

下载系统镜像

下载 centos 6.10 安装包，下载地址：精心整理Linux各版本安装包（包括Centos、Redhat、Oracle Linux），附下载链接🔗

这里的校验码记录一下： 6448e4ec53dce4fd4c6c56fa0a5274df2d87cdab4a3b194f2b9f28fd8cea7e27

下载打包源码

下载打包模板源码：

1	git clone https://hub.fastgit.org/chef/bento.git

将系统镜像文件拷贝至 bento/packer_templates/centos 目录下：

确认环境准备好之后，可以开始进行打包。

开始打包

自定义json文件

使用目录中的 centos-6.10-x86_64.json 文件，复制为 centos610.json ，进行自定义修改：

📢 注意：以下修改两个脚本，提前排坑。

修改 networking.sh 脚本

脚本位于 centos 中，../centos/scripts/networking.sh，由于无法访问 github ，因此 /etc/hosts 需要增加 github ip：

# modify by luciferliu for github raw.githubusercontent.com:443; Connection refused
echo '185.199.108.133 raw.githubusercontent.com' >>/etc/hosts;
echo '185.199.109.133 raw.githubusercontent.com' >>/etc/hosts;
echo '185.199.110.133 raw.githubusercontent.com' >>/etc/hosts;
echo '185.199.111.133 raw.githubusercontent.com' >>/etc/hosts;

echo '54.186.51.210 vault.centos.org' >>/etc/hosts;
echo '3.22.185.178 vault.centos.org' >>/etc/hosts;
echo '34.253.151.233 vault.centos.org' >>/etc/hosts;

ping raw.githubusercontent.com -c 5
ping vault.centos.org -c 5

修改 vagrant.sh 脚本

脚本位于 bento/packer_templates/_common 目录下，由于未关闭防火墙，443端口无法访问，因此一直报错，手动关闭防火墙：

# modify by luciferliu ,443 port is close, stop firewalld.service
RELS=$(cat /etc/system-release)
OS_VER_PRI=$(echo "${RELS#*release}" | awk '{print $1}' | cut -f 1 -d '.')
if [ "${OS_VER_PRI}" -eq 6 ]; then
    service iptables stop
elif [ "${OS_VER_PRI}" -eq 7 ] || [ "${OS_VER_PRI}" -eq 8 ]; then
    systemctl stop firewalld.service
fi

pubkey_url="https://raw.githubusercontent.com/hashicorp/vagrant/master/keys/vagrant.pub";
mkdir -p $HOME_DIR/.ssh;

if command -v curl >/dev/null 2>&1; then
    curl --insecure --location "$pubkey_url" > $HOME_DIR/.ssh/authorized_keys;
elif command -v fetch >/dev/null 2>&1; then
    fetch -am -o $HOME_DIR/.ssh/authorized_keys "$pubkey_url";
elif command -v wget >/dev/null 2>&1; then
    wget --no-check-certificate "$pubkey_url" -O $HOME_DIR/.ssh/authorized_keys;
else
    echo "Cannot download vagrant public key";
    exit 1;
fi
