无人值守安装系统及lamp和storage架构的搭建【Linux运维之道之脚本案例】

主要思路为在default中设置menu.c32中为两个，lamp和storage。其中让它们分别指向不同的ks.cfg文件，ks.cfg1和ks.cfg2。其中ks.cfg1后边添加上执行lamp架构的脚本命令，ks.cfg2后边添加上执行storage架构的脚本命令。在新安装的服务器上就选择lamp和storage就能完成想要的服务器架构。具体步骤如下：

一、批量部署

1.在/home/test下新建文件default  ks.cfg1 ks.cfg2  tftp  dhcp.conf 1

dhcpd.conf 文件内容为

ddns-update-style interim;

ignore client-updates;

option domain-name-servers 192.168.18.101;

default-lease-time 600;

max-lease-time 7200;

subnet 192.168.18.0 netmask 255.255.255.0 {

range 192.168.18.100 192.168.18.200;

option routers 192.168.18.1;

filename "pxelinux.0";

next-server 192.168.18.101;

}

tftp 文件内容为

# default: off

# description: The tftp server serves filesusing the trivial file transfer \

#      protocol.  The tftp protocol isoften used to boot diskless \

#      workstations, download configuration files to network-aware printers, \

#      and to start the installation process for some operating systems.

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

}

2.修改权限

chmod 757 /home/test/ -R

3.执行脚本1

sh  1

二、storage服务器脚本storage

#!/bin/bash

for i in sdb sdc sdd sde

do

fdisk /dev/$i << EOF

n

p

1

t

8e

w

EOF

done

mdadm --create --auto=yes /dev/md1--level=5 --raid-devices=4 /dev/sdb1 /dev/sdc1 /dev/sdd1 /dev/sde1

pvcreate /dev/md1

vgcreate vfastvg /dev/md1

lvcreate -L 8G -n vfastlv vfastvg

mkfs.ext3 /dev/vfastvg/vfastlv

mkdir /mnt/vfast

mount /dev/vfastvg/vfastlv /mnt/vfast

三、lamp服务器脚本

#!/bin/bash

touch /etc/yum.repos.d/server.repo

echo server  > /etc/yum.repos.d/server.repo

echo name=server  >> /etc/yum.repos.d/server.repo

echo baseurl=ftp://192.168.18.101/pub >>/etc/yum.repos.d/server.repo

echo enabled=1 >>/etc/yum.repos.d/server.repo

echo      gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release     >>/etc/yum.repos.d/server.repo

mount /dev/cdrom /mnt

yum install http* -y

yum install mysql* -y
