RockyLinux 9 PXE Server bios+uefi 自动化部署 RockLinux 8 9

pxe server 前言

PXE（Preboot eXecution Environment，预启动执行环境）是一种网络启动协议，允许计算机通过网络启动而不是使用本地硬盘。PXE服务器是实现这一功能的服务器，它提供了启动镜像和引导加载程序，使得客户端计算机可以通过网络启动并安装操作系统或运行其他软件。

在Debian系统中，要设置一个PXE服务器，您需要以下几个组件：

• TFTP服务器：用于提供启动镜像和引导加载程序。
• DHCP服务器：用于分配IP地址给客户端计算机。
• NFS或HTTP服务器：用于提供操作系统镜像和其他文件。

在Debian中，可以使用以下软件包来设置PXE服务器：

• atftpd：一个轻量级的TFTP服务器，可以用于提供启动镜像和引导加载程序。
• dnsmasq：一个轻量级的DHCP和DNS服务器，可以用于分配IP地址给客户端计算机。
• nfs-kernel-server：用于提供NFS服务，以便客户端可以访问操作系统镜像和其他文件。

 创建一键部署pxe server 环境脚本

• pxe server 是RockyLinux 9
• dhcp /etc/dhcp/dhcpd.conf 配置文件
• tftp 配置文件/etc/default/tftpd-hpa
• tftp 69
• http 配置文件/etc/httpd/conf/httpd.conf
• /etc/httpd/conf.d/pxeboot.conf 镜像http配置
• http 端口80
• /var/lib/tftpboot/pxelinux.cfg/default （bios 支持）配置文件
• 10-48 行变量内容详细注意，更改自己需要的，自动化脚本仔细看
• /var/lib/tftpboot/grub.cfg （uefi 支持）配置文件，grub.cfg此处Redhat 系和debian 系不一样哦注意哦
• rockylinux root密码1234.com
• LVM 自动分区，默认禁止/home 分区 
• /var/pxe/{rockylinux8.10,rockylinux9.4} 挂载目录
• /var/www/html/{rockylinux8.10,rockylinux9.4} images目录
• /var/www/html/rockylinx_iso 8 9  iso 下载存放目录
• /var/www/html/rockylinx_cfg{Rockylinux8.10-ks.cfg,Rockylinux9.4-ks.cfg} 自动化编排
• rockylinux cfg编排参考
• redhat cfg 编排参考（需要注册redhat 转换登录）
• PXE网络安装参考,相关配置参考
• bios 实现自动化安装esxi 需要syslinux官方是指导3.86，Redhat 8 系列下使用此 版本

• # 加密密码生成
  python -c 'import crypt,getpass; \
  print(crypt.crypt(getpass.getpass(), \
  crypt.mksalt(crypt.METHOD_SHA512)))'
