1.1 redhat7.9 定制镜像上传到云平台。 这个制作镜像得方式适用于多种iso 镜像。
将iso 镜像通过vmware 创建出一台虚机对虚机做一些基础配置。在虚机上安装kvm 虚拟化得工具 将iso 镜像在导入虚机种通过kvm创建一下虚机 虚机创建出来后会进入安装得界面无法自己引导安装 所以我们通过图形化界面virt-manager 或者console 方法进入引导得界面将虚机生产出来此时得虚机是允许在qcow2 里然后我对这个镜像做定制得配置或者按照。
二、开始制作镜像
2.1 通过vmware 创建新的虚机 2.2 创建自定义虚拟机 2.3 指定系统磁盘容量大小根据自己实际分配 2.4 自定义硬件移除其他不必要的硬件根据自己实际移除。 2.5 指定启动光盘 2.6 启动虚拟机 2.7 根据自身选择语言
本次测试选择英文
2.8 根据需求选择安装信息 本次安装是最小安装模式
2.9 进入分区 2.10 设置密码 2.11 创建完成后重启虚机登录虚机 **到此镜像就准备差不多了如果需要下载安装报自己做一个网络源安装所需要得软件包 **
三、定制配置信息
3.1 指定网卡名为eth0根据需求来做需要就做不需要跳过就好
修改网卡配置文件
