CentOS6.2部署Kickstart无人值守安装环境

 前提条件：

（一）  设置基础网络环境

基础环境配置 [root@server ~]# service iptables stop [root@server ~]# service iptables save             //确认iptables关闭 [root@server ~]# getenforce                        //确认selinux关闭 Disabled [root@server ~]# vim /etc/sysconfig/network-scripts/ifcfg-eth0 //能上网的IP DEVICE=eth0 NM_CONTROLLED=yes ONBOOT=yes BOOTPROTO=dhcp DNS1=202.106.0.20 DNS2=192.168.10.254 [root@server ~]# vim /etc/sysconfig/network-scripts/ifcfg-eth1   //私有IP DEVICE=eth1 NM_CONTROLLED=yes ONBOOT=yes BOOTPROTO=static IPADDR=192.168.10.254 NETMASK=255.255.255.0 [root@server ~]# vim /etc/sysconfig/network                  //设置主机名 NETWORKING=yes HOSTNAME=server.xxx.com GATEWAY=192.168.1.1 [root@server ~]#service network restart

（二）配置ftp yum仓库

安装vsftpd（先挂载ISO到/media下） [root@server ~]# rpm -ivh /media/Packages/vsftpd- 2.2.2 -6.el6_0.1.x86_64.rpm 把CentOS6.2DVD1挂载到/media并将其所有内容拷贝到/var/ftp/pub下相应的目录下 [root@server ~]# cp –rf /media/* /var/ftp/pub/centos/6.2 然后将CentOS6.2DVD2中Packect目录追加到已经存在的Packect中，注意有个别相同的内容可直接覆盖。 [root@server ~]# cp –rf /media/Packect/* /var/ftp/pub/centos/6.2/Packect [root@server ~]#du -sh /var/ftp/pub/centos/6.2/ 5.4G    /var/ftp/pub/centos/6.2/ [root@server ~]# cd /etc/yum.repos.d/ [root@server ~]# rm –rf * [root@server ~]# vim CentOS_6.2.repo [CentOS_6.2] name= CentOS 6.2 baseurl=ftp://192.168.10.254/pub/centos/6.2/ enabled=1 gpgcheck=0 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6 [root@server ~]# yum clean all [root@server ~]# service vsftpd start [root@server ~]# chkconfig vsftpd on

【PXE】

一、             安装TFTP

[root@server ~]# yum -y install tftp-server [root@server ~]# vim /etc/xinetd.d/tftp service tftp {         socket_type             = dgram         protocol                = udp         wait                    = yes         user                    = root         server                  = /usr/sbin/in.tftpd         server_args             = -s /tftpboot         disable                 = no         per_source              = 11         cps                     = 100 2         flags                   = IPv4 } [root@server ~]# service xinetd restart [root@server ~]# chkconfig xinetd on [root@server ~]# netstat -ln | grep :69 udp        0      0 0.0.0 .0:69                   0.0.0 .0:*  [root@server ~]# mkdir /tftpboot/centos6.2 -p [root@server ~]# cp /var/ftp/pub/centos/6.2/images/pxeboot/* /tftpboot/centos6.2/ [root@server ~]# cp /var/ftp/pub/centos/6.2/isolinux/* /tftpboot/centos6.2/ [root@server ~]# yum -y install syslinux [root@server ~]# cp /usr/share/syslinux/pxelinux.0 /tftpboot/ [root@server ~]# mkdir /tftpboot/pxelinux.cfg [root@server ~]# cp /tftpboot/centos6.2/isolinux.cfg /tftpboot/pxelinux.cfg/default [root@server ~]# vim /tftpboot/pxelinux.cfg/default #default vesamenu.c32 default linux …… label linux   menu label ^Install or upgrade an existing system   menu default   kernel centos6.2/vmlinuz   append initrd=centos6.2/initrd.img ks=http://192.168.10.254/ks_centos6.cfg [root@server ~]# chmod 755 /tftpboot/pxelinux.cfg/default

二、 配置DHCP

[root@server ~]# yum -y install dhcp [root@server ~]# cp /usr/share/doc/dhcp- 4.1.1 /dhcpd.conf.sample /etc/dhcp/dhcpd.conf [root@server ~]# vim /etc/dhcp/dhcpd.conf option domain-name "dong.com"; option domain-name-servers 192.168.10.254,202.106.0.20; default-lease-time 600; max-lease-time 7200; next-server 192.168.10.254; filename "pxelinux.0"; subnet 192.168.10.0 netmask 255.255.255.0 {   range 192.168.10.10 192.168.10.20;   option routers 192.168.10.254; } [root@server ~]# service dhcpd restart [root@server ~]# chkconfig dhcpd on

三、 配置NFS/HTTP

[root@server ~]# yum -y install nfs-utils

[root@server ~]# vim /etc/exports

/var/ftp/pub/centos/6.2/ *(ro)

[root@server ~]# /etc/init.d/rpcbind restart

[root@server ~]# /etc/init.d/nfs restart

[root@server ~]# chkconfig rpcbind on

[root@server ~]# chkconfig nfs on

[root@server ~]# yum -y install httpd

[root@server ~]# cp anaconda-ks.cfg /var/www/html/ks_centos6.cfg

[root@server ~]# /etc/init.d dhcpd restart

[root@server ~]# chkconfig dhcpd on

四、配置Kickstart

[root@server ~]# yum -y install system-config-kickstart

[root@server ~]# system-config-kickstart               //启动kickstart配置

 

 

附:ks_centos6.cfg

[root@server ~]# cat /var/www/html/ks_centos6.cfg firewall --disabled install nfs --server=192.168.10.254 --dir=/var/ftp/pub/centos/6.2/ rootpw --iscrypted $1$jh50MQCb$XcqqaAtp9B/MXmV1buQId0 auth --useshadow --passalgo=sha512 text firstboot --disable keyboard us lang en_US selinux --disabled logging --level=info reboot timezone --isUtc Asia/Shanghai network --bootproto=dhcp --device=eth0 --onboot=on bootloader --location=mbr zerombr clearpart --all --initlabel part /data --fstype="ext4" --size=5000 part swap --fstype="swap" --size=2048 part /boot --fstype="ext4" --size=200 part / --fstype="ext4" --size=10000 %packages @base %post --interpreter=/bin/bash rm -rf /etc/yum.repos.d/* echo '[centos6] name=centos6 baseurl=ftp://192.168.10.254/pub/CentOS/6.2/ enabled=1 gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6' > /etc/yum.repos.d/centos6.repo %end
