kickstart 实战
http://man.linuxde.net/download/CentOS_6_9镜像
安装:
关闭防火墙
且在编辑虚拟网络的vnet8中要取消使用本地dhcp项
1.yum -y install dhcp
[root@centos6 ~ ]#vim /etc/dhcp/dhcpd.conf
#
# DHCP Server Configuration file.
# see /usr/share/doc/dhcp*/dhcpd.conf.sample
# see ‘man 5 dhcpd.conf‘
#
subnet 192.168.5.0 netmask 255.255.255.0 {
range 192.168.5.100 192.168.5.120;
option routers 192.168.5.1;
option subnet-mask 255.255.255.0;
default-lease-time 21600;
max-lease-time 43200;
next-server 192.168.5.103;
filename "/pxelinux.0";
}
[root@centos6 ~ ]#vim /etc/sysconfig/dhcpd
# Command line options here
DHCPDARGS=eth0
[root@centos6 ~ ]#/etc/init.d/dhcpd start
2.[root@centos6 ~ ]#yum -y install tftp-server
[root@centos6 ~ ]#cat -n /etc/xinetd.d/tftp
14 disable = yes
只改第14行的yes为no
[root@centos6 ~ ]#sed -i ‘14s%yes%no%‘ /etc/xinetd.d/tftp
[root@centos6 ~ ]#/etc/init.d/xinetd restart
Stopping xinetd: [FAILED]
Starting xinetd: [ OK
3.[root@centos6 ~ ]#yum install httpd -y
[root@centos6 ~ ]#grep -n ServerName /etc/httpd/conf/httpd.conf
265:# ServerName gives the name and port that the server uses to identify itself.
276:#ServerName www.example.com:80
283:# ServerName directive.
1006:# ServerName dummy-host.example.com
在277行插入一条如下
[root@centos6 ~ ]#sed -i "277i ServerName 127.0.0.1:80" /etc/httpd/conf/httpd.conf
[root@centos6 ~ ]#/etc/init.d/httpd start
[root@centos6 ~ ]#netstat -tunlp|grep 80
tcp 0 0 :::80 :::* LISTEN 9474/nginx
看上面是80端口的里程起不来,那看一下进程号,原来是被nginx占用了,直接杀掉该进程号
[root@centos6 ~ ]#kill 9474
[root@centos6 ~ ]#mkdir /var/www/html/CentOS-6.9
[root@centos6 ~ ]#mount /dev/cdrom /var/www/html/CentOS-6.9
在浏览器输入ip/并刚才挂载的目录名,效果如下图
4.安装启动引导程序/及pxe引导配置
[root@centos6 ~ ]#yum -y install syslinux
[root@centos6 ~ ]#cp /usr/share/syslinux/pxelinux.0 /var/lib/tftpboot/(tftp根目
把菜单(启动相关的程序)复制过去
[root@centos6 ~ ]#cp -a /var/www/html/CentOS-6.9/isolinux/* /var/lib/tftpboot/
新建pxelinux.cfg目录,存放客户端配置文件
[root@centos6 ~ ]#mkdir -p /var/lib/tftpboot/pxelinux.cfg
[root@centos6 ~ ]#cp /var/www/html/CentOS-6.9/isolinux/isolinux.cfg /var/lib/tftpboot/pxelinux.cfg/default
如果你想用网络安装方式,那么此时就可以安装了(不要挂载镜像)
5.pxe配置文件default解析
6.创建自动应答文件ks.cfg
[root@centos6 ~ ]# grub-crypt
Password:181818
Retype password:181818

[root@centos6 ~ ]#mkdir /var/www/html/ks_config
# Kickstart Configurator for CentOS 6.7 by yao zhang
[root@centos6 ~ ]#vim /var/www/html/ks_config/CentOS-6.9-ks.cfg

7.开机优化脚本

8.整合编辑default配置文件
[root@centos6 ~ ]#vim /var/lib/tftpboot/pxelinux.cfg/default
default ks
prompt 0
label ks
kernel vmlinuz
append initrd=initrd.img ks=http://192.168.5.103/ks_config/CentOS-6.9-ks.cfg
ksdevice=eth0
[root@centos6 ~ ]#curl http://192.168.5.103/ks_config/CentOS-6.9-ks.cfg 测试下刚才文件有没有对,如果出来的结果是/var/www/html/ks_config/CentOS-6.9-ks.cfg 的内容说明ok
至此一切准备工作就做完了
[root@centos6 ~ ]#netstat -ntulp|egrep ‘80|67|69‘
确认有没有80端口,67,69端口
此时启动空白的无人机就行了
[root@centos6 ~ ]#tailf /var/log/messages 可以观看日志过程
