[1]kickstart一键自动安装Linux系统

kickstart，无人值守，自动安装系统。本文介绍kickstart的用法。

 

#安装系统的信息——可以参考
[root@larrywen pdf]# vim ~/anaconda-ks.cfg

第一步 安装kickstart 

[root@larrywen /]#yum installsystem-config-kickstart -y
#退出，再以X Window的形式登录
[root@serv01 opt]# exit
logout
Connection to 192.168.1.11 closed.
[root@larrywen Desktop]# ssh 192.168.1.11-X
[root@larrywen Desktop]#system-config-kickstart

第二步 生成ks.cfg文件

 

第一项，基本配置。默认语言选择English(USA)，键盘选择U.S.English，时区选择Africa/Chongqing，虚拟机下不建议勾选"Use UTC clock"，设定root密码，如果我们不选择加密root密码，生成的文件中密码就以明文显示，高级配置中把目标架构选择x86, AMD64, or Intel EM64T，然后把"Rebootsystem after installation"。



第二项，安装方法。安装方法选择“Perfome new installation(新安装)"，安装源选择NFS，NFS 服务器：192.168.1.11，NFS 目录：/iso      

 


第三项，Boot Loader 选项。安装类型选择：安装新的boot loader，GRUB 忽略不写，这个是启动GRUB时使用的密码，如果没设置GRUB密码，进入单用户模式是可以的，但是设置了GRUB密码后，进入单用户模式必须输入GRUB密码。安装选项把"Install boot loader on Master Boot Record(MBR)"勾选该上，内核参数忽略。

 


第四项，Partition Information(分区信息)。Master Boot Record：Clear Master Boot Record（清除MBR）。Partitions：Remove allexisting partitions（移除所有存在的分区）。Disk label：Do not initialize the disk lable（不初始化卷标）。布局：测试用：我这样分区：/boot(200M) swap(1024M) /(其他的空间分配给根分区）。

                


第五项，Network Configuration（网络配置）。我们配置一个eth0，自动获取IP。      



第六项，Authentication（验证）。保持默认即可。



第七项，Firewall Configuration（防火墙配置）。我们激活SELinux，启用防火墙，信任的服务把SSH勾选上。



第八项，Display Configuration（显示配置）。在图形化环境安装后，我们第一次启动时把配置的图形化界面禁用掉。



第九项，Package Selection（包的选择）。在语言包中把“Chinese Support（中文支持”勾选上。



第十项，Pre-Installation Script（安装前脚本）。这是在安装前执行的脚本，此处忽略。



第十一项，Post-Installation（安装后脚本）。这是安装后执行的脚本，此处我们添加两条命令，以做测试。



useradd oracle;
echo "testoracle" | passwd--stdin oracle;

#查看配置的文件
[root@serv01 opt]# cat ks.cfg
#platform=x86, AMD64, or Intel EM64T
##version=DEVEL
## Firewall configuration
#firewall --enabled --ssh
## Install OS instead of upgrade
#install
## Use NFS installation media
#nfs --server=192.168.1.11 --dir=/iso
## Root password
#rootpw --plaintext uplooking
## 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 --enforcing
## Installation logging level
#logging --level=info
## Reboot after installation
#reboot
## System timezone
#timezone Asia/Chongqing
## Network information
#network --bootproto=dhcp --device=eth0 --onboot=on
## System bootloader configuration
#bootloader --location=mbr
## Clear the Master Boot Record
#zerombr
## Partition clearing information
#clearpart --all 
## Disk partitioning information
#part /boot --fstype="ext4"--size=200
#part swap --fstype="swap"--size=1024
#part / --fstype="ext4" --grow--size=1
#
#%post
#useradd oracle;
#echo "uplooking" | passwd--stdin oracle;
#%end
#
#%packages
#@chinese-support
#
#%end
#

第三步 配置nfs 

[root@serv01 opt]# vim /etc/exports
[root@serv01 opt]# cat /etc/exports
/iso *(ro)
/opt *(ro)
 
#安装nfs相关的RPM包
[root@serv01 opt]# yum install nfs* -y
 
Installed:
 nfs-utils.x86_64 1:1.2.3-7.el6          nfs-utils-lib.x86_64 0:1.1.5-3.el6           nfs4-acl-tools.x86_64 0:0.3.3-5.el

# mount /wolfback
Replaying log for /dev/wolfbacklv.
mount: 0506-324 Cannot mount /dev/wolfbacklv on /wolfback: The media is not formatted or the format is not correct.
0506-342 The superblock on /dev/wolfbacklv is dirty.  Run a full fsck to fix.

# fsck -p /wolfback

 

The current volume is: /dev/wolfbacklv
Primary superblock is valid.
J2_LOGREDO:log redo processing for /dev/wolfbacklv                   
Primary superblock is valid.
*** Phase 1 - Initial inode scan
*** Phase 2 - Process remaining directories
*** Phase 3 - Process remaining files
*** Phase 4 - Check and repair inode allocation map
*** Phase 5 - Check and repair block allocation map
File system is clean.
Superblock is marked dirty (FIXED)
All observed inconsistencies have been repaired.
