EVE-NG【镜像篇】

eve-ng - 这篇文章属于一个选集。

§ 1: 本文

EVE-NG 仿真虚拟环境是一种新兴的虚拟无缝仿真平台，可以满足当今 IT 世界的需求。无客户端管理将使 EVE-NG 成为企业工程师的最佳选择，而不受企业安全策略的影响，因为它可以在完全隔离的环境中运行。

镜像制作
#

准备环境
#

说明	类型	描述
eve-ng	企业版、社区版	eve-ng环境
ISO	ISO	镜像文件(Ubuntu、Debian、RockyLinux等)

制作镜像
#

准备环节
#

本次制作以ubuntu 22.04.5为例，对于其他发行版同样适用。

创建目录: 路径/opt/unetlab/addons/qemu

cd /opt/unetlab/addons/qemu

# 创建目录；名字按照eve-ng要求
mkdir linux-ubuntu-22.04.5

上传镜像文件；重命名为cdrom.iso

root@eve-ng:/opt/unetlab/addons/qemu/linux-ubuntu-22.04.5# ls -ltr
total 5601436
-rw-r--r-- 1 root unl  3598123008 Nov  1 13:27 virtioa.qcow2
-rw-r--r-- 1 root root 2136926208 Nov  3 02:56 cdrom.iso

创建virtioa.qcow2文件

qemu-img create -f qcow2 virtioa.qcow2 50G

安装环节
#

浏览器打开eve-ng WEB UI
添加新的实验室

打开新实验室，并添加节点，选择之前创建的目录名字；保存

启动阶段，并双击节点打开console；按照Linux正常引导进行安装
安装完成后，自定义一些配置
1. 开启rootSSH 登录
2. 关闭防火墙
配置完成；关闭节点

转换镜像
#

打开实验室，记住实验ID

转换镜像

一个实验室有多个节点时，请根据需求选择对应的节点ID目录

cd /opt/unetlab/tmp/0/{实验ID}/{节点ID}

转换virtioa.qcow2

qemu-img convert -O qcow2 virtioa.qcow2 virtiob.qcow2

拷贝镜像

# 1. 建议提前删除镜像
rm -rf /opt/unetlab/addons/qemu/linux-ubuntu-22.04.5/virtioa.qcow2

# 2. 拷贝镜像
cp virtiob.qcow2 /opt/unetlab/addons/qemu/linux-ubuntu-22.04.5/virtioa.qcow2

修复权限

/opt/unetlab/wrappers/unl_wrapper -a fixpermissions

删除实验室
创建新实验室，选择镜像；启动节点。愉快的做实验吧

其他类型
#

选择节点时，如果看不到镜像，请在此处复制一个模版/opt/unetlab/html/templates/intel，根据需求修改即可。

iStoreOS
#

创建iStoreOS镜像，本人在此处复制linux模版进行修改。
