KickStart Operation Guide
Note:以下所有命令及涉及到的脚本均在RHEL 6.6 / VMWare上测试通过。
主机配置:eth0为对外服务网卡,eth1为VMWare local模式连接,用于KickStart安装系统使用。
(一) 安装所需的软件包
为了避免缺失依赖包带来的麻烦,建议采用安装DVD做为repo源。
[root@KioskStar pub]# mount /dev/sr0 /media/cdrom
[root@KioskStar pub]# mkdir /var/ftp/pub/inst_img
[root@KioskStar pub]# cp –p –R /media/cdrom /var/ftp/pub/inst_img
[root@KioskStar pub]# umount /media/cdrom
[root@KioskStar pub]# vi /etc/yum.repos.d/local_dvd.repo

安装所需软件包:
# yum install dnsmasq syslinux tftp-server vsftpd system-config-kickstart -y
(二) Config tftp / PXE
# cp -r /usr/share/syslinux/* /var/lib/tftpboot
# mkdir /var/lib/tftpboot/pxelinux.cfg
# touch /var/lib/tftpboot/pxelinux.cfg/default
编辑/etc/dnsmasq.conf内容:

(三) 调整关闭Service
为了方便配置,减少配置防火墙的工作,本文档中关闭了selinux和firewall,在企业生产环境中视情况而定,看看是否需要进行对应配置。
# echo 0 > /selinux/enforce
# vi /etc/selinux/config
修改SELINUX=enforcing为SELINUX=disabled
# cp /usr/share/syslinux/pxelinux.0 /var/lib/tftpboot
#for SVRES in 3 4 5
do
chkconfig --level $SVRES dnsmasq on
chkconfig --level $SVRES vsftpd on
chkconfig --level $SVRES ip6tables off
chkconfig --level $SVRES iptables off
done
# chkconfig --list | grep -e tables -e dnsmasq -e vsftpd
# service ip6tables stop
# service iptables stop
# service dnsmasq start
# service vsftpd start
(四) 客户端自动安装场景测试记录
