实验要求
1. 自动安装ubuntu server20以上版本
2. 自动部署三台Rockylinux9服务器最小化安装安装基础包并设定国内源设静态IP 实验步骤 安装软件 # yum源必须有epel源 # dnf install -y epel-release #关闭防火墙和selinux systemctl stop firewalld systemctl disable firewalld sed -i s/^SELINUX.*/SELINUXdisabled/g /etc/selinux/config # reboot 三、部署Cobbler
1、安装软件 # dnf -y install cobbler dhcp-server
dnf -y install syslinux dnf-plugins-core pykickstart
创建三台虚拟机设定MAC地址 将三台虚拟机的MAC地址记录下来 00:50:56:3B:64:2F
00:50:56:23:4A:8E
00:50:56:39:61:7A 2、配置cobbler 1修改Cobbler主配置文件 # 生成密文密码 openssl passwd -1 qweasd
$1$hNAtwYE4$.l1apMwOWpCDpSmE.MBdG0 #设置root密码
vi /etc/cobbler/settings.yaml
default_password_crypted: $1$hNAtwYE4$.l1apMwOWpCDpSmE.MBdG0
$1$hNAtwYE4$.l1apMwOWpCDpSmE.MBdG0 # cobbler接管dhcp manage_dhcp: true manage_dhcp_v4: true #cobbler服务器地址 server: 192.168.8.100 --指定自己的ip地址 #tftp地址 next_server_v4: 192.168.100.128 --指定自己的ip地址 #cobbler接管tftp manage_tftpd: true #当bios首选启动项是pxe时此项设置为true可避免重启反复安装系统否则为false pxe_just_once: true 修改dhcp模版文件
添加 host server01 { hardware ethernet 00:50:56:3B:64:2F; fixed-address 192.168.8.110; } host server02 { hardware ethernet 00:50:56:23:4A:8E; fixed-address 192.168.8.120; } host server03 { hardware ethernet 00:50:56:39:61:7A; fixed-address 192.168.8.130; } # vi /etc/cobbler/dhcp.template …… subnet 192.168.8.10 netmask 255.255.255.0 { #-网段和子网掩码 option routers 192.168.8.2; #-网关 option domain-name-servers 8.8.8.8; #dns option subnet-mask 255.255.255.0; range dynamic-bootp 192.168.8.100 192.168.8.254; #--起始范围 host server01 { hardware ethernet 00:50:56:3B:64:2F; #-复制自己生成的mac地址 fixed-address 192.168.8.110; } host server02 { hardware ethernet 00:50:56:23:4A:8E; fixed-address 192.168.8.120; } host server03 { hardware ethernet 00:50:56:39:61:7A; fixed-address 192.168.8.130; } default-lease-time 21600; max-lease-time 43200; next-server $next_server_v4; …… 3启动cobbler同步配置 # systemctl enable --now cobblerd # cobbler sync 4启动dhcp、tftp、http服务 # systemctl enable --now tftp httpd dhcpd #生成引导加载程序 cobbler mkloaders 此命令适用cobblerV3.3.1及之后的版本 # cobbler mkloaders # 查看 # ls /var/lib/cobbler/loaders/ grub libcom32.c32 linux.c32 menu.c32 ldlinux.c32 libutil.c32 memdisk pxelinux.0 3、导入系统镜像资源 # 挂载光盘镜像
# mount /dev/cdrom /mnt/ #虚拟机挂载
# 导入系统镜像资源并查看 cobbler profile add --name rocky-9-x86_64 --distrorocky-9-x86_64 --autoinstallrocky9.ks # cobbler distro list
rocky-9-x86_64 # cobbler profile list rocky-9-x86_64 注导入的镜像资源存放在 /var/www/cobbler/distro_mirror/目录中。 #重启cobbler同步配置 # systemctl restart cobblerd # cobbler sync #查看生成的启动菜单 # cat /var/lib/tftpboot/pxelinux.cfg/default
