目录
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 Oracle Linux 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: 625044388ee60a031965a42a32f4c1de0c029268975edcd542fd14160e0dadcb
下载打包源码
下载打包模板源码:
git clone https://hub.fastgit.org/chef/bento.git
将系统镜像文件拷贝至 bento/packer_templates/oraclelinux
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 oracle-6.10-x86_64.json
文件,复制为 oraclelinux610.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;
ping raw.githubusercontent.com -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 ]; 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
启动 packer 进行打包
packer build -only=virtualbox-iso oraclelinux610.json
显示如上,即已经打包成功,box 位置存放在:../../builds/oraclelinux6.10.virtualbox.box
。
上传 box 镜像
不做演示,比较简单。
box镜像下载地址:luciferliu/oraclelinux6.10
写在最后
为什么要打包 box 镜像盒子? 以后可以使用 vagrant 直接初始化创建 linux 系统,不需要再一步步创建,为自动化奠定基础。
