PXE无人值守安装ubuntu1804系统（kickstart无人值守安装Ubuntu1804系统）

 

 

 

从以下截图可以看出，自动化安装ubuntu系统已经成功，进入安装软件包界面

一开始错误原因： domain-name-servers配置错了，网络没通，后来改为114.114.114.114进行域名解析就对了，然后重启dhcpd服务

 正在安装系统软件：

 

 参考文档：

kickstart无人值守安装Ubuntu1804系统

1.安装配置DHCP服务

apt install isc-dhcp-server -y
vim /etc/dhcp/dhcpd.conf
#配置文件最后插入
subnet 10.0.0.0 netmask 255.255.255.0 {
range 10.0.0.70 10.0.0.90;
option routers 10.0.0.2;
option domain-name-servers 10.0.0.2;
default-lease-time 600;
max-lease-time 7200;
next-server 10.0.0.200;
filename "pxelinux.0";
}
systemctl start isc-dhcp-server
systemctl enable isc-dhcp-server
netstat -lntup |grep 67

2.安装配置FTP服务

apt install tftpd-hpa -y

#我这里配置文件保持默认
root@cxy:~# vim /etc/default/tftpd-hpa
# /etc/default/tftpd-hpa

TFTP_USERNAME="tftp"
TFTP_DIRECTORY="/var/lib/tftpboot"
TFTP_ADDRESS=":69"
TFTP_OPTIONS="--secure"

systemctl start tftpd-hpa.service
systemctl enable tftpd-hpa.service
netstat -lntup |grep 69

3.安装配置HTTP服务以及挂载ISO至HTTP站点目录

apt install apache2 -y
systemctl start apache2
systemctl enable apache2
#上传ISO至根目录
mkdir -p /var/www/html/ubuntu
mount /root/ubuntu-18.04.5-live-server-amd64.iso /var/www/html/ubuntu

4.下载对应系统的netboot.tar包并且解压放至网络引导启动的根路径下

Ubuntu系统Netboot Images下载

#解压之后查看
root@cxy:/var/www/html# cd /var/lib/tftpboot/
root@cxy:/var/lib/tftpboot# ls
ldlinux.c32 pxelinux.0 pxelinux.cfg ubuntu-installer version.info

5.配置Kickstart应答文件

cxy@cxy:~$ cat /var/www/html/ks_ubuntu1804.cfg
