定制CentOS 6.3 自动安装盘

一、之前有写过一篇管理定制CentOS5.6的文章，最近公司外网生产环境准备用CentOS6系列的，手动安装是在是太麻烦，所以就又研究了一些6系列的封装，其实和5系列的差不多，就是有几个文件不一样，还有就是ks.cfg这个文件我又更新了新内容。二、开始定制1、安装需要的用到的软件包[root@localhost ~]# yum -y install createrepo mkisofs2、生成安装系统所需要的rpm文件列表[root@localhost ~]# awk "/Installing/{print $2}" install.log |sed "s/^[0-9]*://g" >/root/packages.list3、创建工作目录[root@localhost ~]# mkdir -p /mnt/cdrom[root@localhost ~]# mkdir -p /data/OS[root@localhost ~]# mount /dev/cdrom /mnt/cdrom4、复制文件[root@localhost ~]# rsync -a --exclude=Packages /mnt/cdrom/* /data/OS/[root@localhost ~]# cp /mnt/cdrom/.discinfo /data/OS/5、复制精简后的rpm包a、撰写脚本[root@localhost ~]# vi /data/cprmps.sh #！/bin/bash DEBUG=0 CentOS_DVD=/mnt/cdrom ALL_RPMS_DIR=/mnt/cdrom/Packages KOS_RPMS_DIR=/data/OS/Packages packages_list=/root/packages.list number_of_packages=`cat $packages_list | wc -l` i=1 while [ $i -le $number_of_packages ] ; do line=`head -n $i $packages_list | tail -n -1` name=`echo $line | awk "{print $1}"` version=`echo $line | awk "{print $3}" | cut -f 2 -d :` if [ $DEBUG -eq "1" ] ; then echo $i: $line echo $name echo $version fi if [ $DEBUG -eq "1" ] ; then ls $ALL_RPMS_DIR/$name-$version* if [ $？ -ne 0 ] ; then echo "cp $ALL_RPMS_DIR/$name-$version* " fi else echo "cp $ALL_RPMS_DIR/$name-$version* $KOS_RPMS_DIR/" cp $ALL_RPMS_DIR/$name-$version* $KOS_RPMS_DIR/ # in case the copy failed if [ $？ -ne 0 ] ; then echo "cp $ALL_RPMS_DIR/$name-$version* " cp $ALL_RPMS_DIR/$name* $KOS_RPMS_DIR/ fib、复制[root@localhost ~]# chmod +x /data/cprmps.sh [root@localhost ~]# sh /data/cprmps.sh 6、撰写ks.cfg文件[root@localhost ~]# vi /data/OS/isolinux/ks.cfg # Kickstart file automatically generated by anaconda. #Install OS instead of upgrade install #Use text mode install text #Use CDROM installation media cdrom lang en_US.UTF-8 keyboard us #Skip the X Configuration skipx #Network informationnetwork --bootproto=static --ip=172.28.26.100 --netmask=255.255.255.0 --gateway=172.28.28.1 --nameserver 8.8.8.8 --hostname=kingsoft-navy --noipv6 --onboot=yes#root -- 1q2w3e rootpw --iscrypted $1$UJlaGQFP$.Wf93SJYnar9yDIzS8YDr1 firewall --disabled #System authorization information authconfig --enableshadow --enablemd5 selinux --disabled timezone --utc Asia/Shanghai #System bootloader configuration bootloader --location=mbr #Clear the Master Boot Record zerombr yes #Partition clearing information bootloader --location=mbrclearpart --linuxpart /boot --fstype ext3 --size=200 --asprimarypart pv.4 --size=30000part swap --size=32000part pv.7 --size=100 --growvolgroup VolGroupRoot --pesize=32768 pv.4volgroup VolGroupData --pesize=32768 pv.7logvol /data/logs --fstype ext3 --name=LogVolLogs --vgname=VolGroupData --size=10240logvol /data --fstype ext3 --name=LogVolData --vgname=VolGroupData --size=59904logvol / --fstype ext3 --name=LogVolRoot --vgname=VolGroupRoot --size=29984 #--- Reboot the host after installation is done reboot %packages @additional-devel@base@core@development@emacs@server-policy@system-managementlibXinerama-develxorg-x11-proto-develstartup-notification-devellibgnomeui-devellibbonobo-develcmakerpmdevtoolsjpackage-utilsrpmlint%post # file descriptors ulimit -HSn 655350echo "* soft nofile 655350" >> /etc/security/limits.conf echo "* hard nofile 655350" >> /etc/security/limits.conf#set iptables/bin/cat > /etc/sysconfig/iptables << _iptables# Generated by iptables-save v1.3.5 on Sun Jul 22 18:22:41 2012*filter:INPUT ACCEPT [0:0]:FORWARD ACCEPT [0:0]:OUTPUT ACCEPT [458589544:2196099698813]:RH-Firewall-1-INPUT -
