centos定制
centos定制
centos定制主要是制作合适自己的iso系统进行批量安装，此例制作出来的iso是一个lnmp环境，其中Nginx、PHP为自己打包的rpm包。iso制作方法参照了http://www.lampbo.org/linux-xuexi/linux-advance/diy-centos6.html
1、安装centos6，本例使用的是centos6.4-minimal系统
wgethttp://mirrors.sohu.com/centos/6.4/isos/x86_64/CentOS-6.4-x86_64-minimal.iso
2、安装制作工具
yum-yinstallanacondarepodatacreaterepomkisofs
3、挂载光盘
mkdir/mnt/cd1 mount/dev/cdrom/mnt/cd1
4、 创建ios制作目录，将光盘内容拷贝到该目录
mkdir/mnt/centos cp-rp/mnt/cd1/*/mnt/centos cp/mnt/.discinfo/mnt/.treeinfo/mnt/centos
5、 配置kickstart文件，实现系统定制化安装依靠该文件
vi/mnt/centos/isolinux/ks.cfg#Kickstartfileautomaticallygeneratedbyanaconda.#version=DEVELinstall#表示是安装，而不是升级cdrom#安装方式langen_US.UTF-8#语言keyboardus#键盘network--onbootno--deviceeth0--bootprotodhcp--noipv6#网络rootpw--iscrypted$6$QmGgBxnXalA0DBxs$gtaacsziglTjjNJwNYKWP/QOjqXDvlmkgBGxROU5dL25x7LIizk4Ol8CTINfWQdalpzvji22GkNU9UxZsJ2jP/#root密码，默认123456firewall--service=ssh#开启防火墙，打开sshauthconfig--enableshadow--passalgo=sha512#加密方式selinux�Cdisabled#关闭selinuxtimezone--utcAsia/Shanghai#时区bootloader--location=mbr--driveorder=sda#引导程序相关参数#Thefollowingisthepartitioninformationyourequested#Notethatanypartitionsyoudeletedarenotexpressed#heresounlessyouclearallpartitionsfirst,thisis#notguaranteedtowork#clearpart--linux--drives=sda#volgroupVolGroup--pesize=4096pv.008002#logvol/--fstype=ext4--name=lv_root--vgname=VolGroup--grow--size=1024--maxsize=51200#logvolswap--name=lv_swap--vgname=VolGroup--grow--size=4032--maxsize=4032#part/boot--fstype=ext4--size=500#partpv.008002--grow--size=1#repo--name="CentOS"--baseurl=cdrom:sr0--cost=100%packages--nobase#需要安装的软件包@安装软件包组--不安装的软件@core apr autoconf automake cloog-ppl cpp fontconfig fontconfig-devel gcc gcc-c++ gd glib2-devel keyutils-libs-devel libgomp libICE libidn-devel libjpeg-turbo libjpeg-turbo-devel libpng libpng-devel libsepol-devel libSM libstdc++-devel libtool libX11 libX11-common libX11-devel libXau libXau-devel libxcb libxcb-devel libXext libxml2 libxml2-devel libXpm libXpm-devel libXt make mpfr ncurses-devel pcre-devel perl perl-DBD-MysqL perl-DBI pkgconfig ppl xorg-x11-proto-devel zlib-devel libmcrypt Nginx PHP MysqL MysqL-server %post#安装后执行脚本echo-ne" *softnofile65535 *hardnofile65535 ">>/etc/security/limits.conf#setsysctltrue>/etc/sysctl.conf cat>>/etc/sysctl.conf<<EOF net.ipv4.ip_forward=0net.ipv4.conf.default.rp_filter=1net.ipv4.conf.default.accept_source_route=0kernel.sysrq=0kernel.core_uses_pid=1net.ipv4.tcp_syncookies=1kernel.msgmnb=65536kernel.msgmax=65536kernel.shmmax=68719476736kernel.shmall=4294967296net.ipv4.tcp_tw_reuse=1net.ipv4.tcp_tw_recycle=1net.ipv4.tcp_fin_timeout=30net.ipv4.tcp_max_tw_buckets=5000net.ipv4.tcp_keepalive_time=600net.ipv4.tcp_synack_retries=5net.ipv4.tcp_syn_retries=1net.ipv4.ip_local_port_range=102465535EOF /sbin/sysctl-p %end
6、将需要安装的rpm包到/mnt/centos/Packages目录下
7、修改isolinux.cfg启动文件
vi/mnt/centos/isolinux/isolinux.cfg labellinux menulabel^Installorupgradeanexistingsystem menudefault kernelvmlinuz appendks=cdrom:/isolinux/ks.cfginitrd=initrd.img
8、修改comps.xml文件，每次在/mnt/centos/Packages目录添加rpm包后需要更新此文件
cd/mnt/centos
mv/mnt/centos/repodata/*-comps.xmlcomps.xml
ls/mnt/centos/repodata/|grep-v“comps.xml”|xargs-Irm-f{}
createrepo-g/mnt/centos/repodata/comps.xml
mv/mnt/centos/repodata/*-comps.xmlcomps.xml
declare-xdiscinfo=`head-1/mnt/centos/.discinfo`
createrepo-u"media://$discinfo"-grepodata/comps.xml/mnt/centos
cd/mnt/centos mkisofs-ocentos6.4-sylee-x86_64.iso-bisolinux/isolinux.bin-cisolinux/boot.cat-no-emul-boot-boot-load-size4-boot-info-table-R-J-v-T/mnt/centos/
