erw23312

环境：
    dhcp服务器：172.168.0.1
    tftp+pxe服务器：172.168.0.2
   配置DHCP服务器
一、配置本地yum源

1 2 3 4 5 6 7 8 9

mount /dev/cdrom /mnt rm -rf /etc/yum.repos.d/* vi /etc/yum.repos.d/base.repo     [base]     name=base     baseurl=file:///mnt     enabled=1     gpgcheck=0     yum repolist

二、安装配置dhcp

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

yum -y install dhcp cp /usr/share/doc/dhcp-4.1.1/dhcpd.conf.sample /etc/dhcp/dhcpd.conf cat /etc/dhcp/dhcpd.conf | grep -v "^$" | grep -v "^#"     option domain-name "parpar.com";     option domain-name-servers 8.8.8.8;     default-lease-time 3600;     max-lease-time 7200;     log-facility local7;     subnet 172.168.0.0 netmask 255.255.0.0 {         range 172.168.0.20 172.168.0.30;         option routers 172.168.0.1;         next-server 172.168.0.2;         filename "pxelinux.0";     } chkconfig dhcpd on service dhcpd start

配置tftp+http+pxe服务器
一、安装配置tftp

1 2 3

yum -y install tftp tftp-server chkconfig tftp on service xinetd start

二、配置PXE工作环境

1 2	yum -y install syslinux cp /usr/share/syslinux/pxelinux.0 /var/lib/tftpboot/

三、提供引导内核文件

1 2 3 4

cp /mnt/images/pxeboot/{vmlinuz,initrd.img} /var/lib/tftpboot/ cp /mnt/isolinux/{vesamenu.c32,boot.msg,splash.jpg} /var/lib/tftpboot mkdir /var/lib/tftpboot/pxelinux.cfg cp /mnt/isolinux/isolinux.cfg /var/lib/tftpboot/pxelinux.cfg/default

四、安装配置httpd服务

1 2 3 4

yum -y install httpd mkdir /var/www/html/centos6 mount --bind /mnt /var/www/html/centos6 service httpd start

五、生成ks文件

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48

yum -y install system-config-kickstart system-config-kickstart mv ks.cfg /var/www/html/ cat /var/www/html/ks.cfg     #platform=x86, AMD64, or Intel EM64T     #version=DEVEL     # Firewall configuration     firewall --disabled     # Install OS instead of upgrade     install     # Use network installation     url --url="http://172.168.0.2/centos6"     repo --name="CentOS" --baseurl=http://172.168.0.2/centos6 --cost=100     # Root password     rootpw --iscrypted $1$10KAJR0t$WqUKt8fRa24FDPnHZxRTZ1     # System authorization information     auth  --useshadow  --passalgo=sha512     # Use graphical install     graphical     firstboot --disable     # System keyboard     keyboard us     # System language     lang en_US     # SELinux configuration     selinux --disabled     # Installation logging level     logging --level=info     # Reboot after installation     reboot     # System timezone     timezone  Asia/Shanghai     # Network information     network  --bootproto=dhcp --device=eth0 --onboot=on     # System bootloader configuration     bootloader --append="crashkernel=auto rhgb quiet" --location=mbr --driveorder="sda"     # Clear the Master Boot Record     zerombr     # Partition clearing information     clearpart --all --initlabel     # Disk partitioning information     part /boot --fstype="ext4" --size=200     part swap --size=4000     part / --fstype="ext4" --grow --size=200     %packages     @core        %end

六、修改   

1 2 3 4 5 6

vim /var/lib/tftpboot/pxelinux.cfg/default     label linux     menu label ^Install or upgrade an existing system     menu default     kernel vmlinuz     append ks=http://172.168.0.2/ks.cfg initrd=initrd.img

九、配置完成,新启动虚拟机即可自动安装系统
