Cobbler实现自动化升级系统到6

1.cobbler安装

 使用脚本安装。install_cobbler.sh

################ IBM的ipmi over lan：
#F1进入BIOS
#System Settings->Devices and I/O Ports->Console Redirection Settings->Serial Port Sharing 将此项设置为Enable即可
#legacy only的引导顺序必须位于pxe之前，否则会进入efi引导，导致安装不成功。若手动选，也不能选pxe，需要选legacy only

#或者远程登入DRAC执行命令 racadm config -g cfgIpmiLan -o cfgIpmiLanEnable 1

2.挂载镜像和导入kickstart

mkdir -p /data/iso && cd /data/iso
wget http://centos.yum.sandai.net/centos/6.4/isos/x86_64/CentOS-6.4-x86_64-bin-DVD1.iso
mkdir CentOS-6.4-x86_64
mount -o loop CentOS-6.4-x86_64-bin-DVD1.iso CentOS-6.4-x86_64
echo "/data/iso/CentOS-6.4-x86_64" >> /usr/local/monitor-base/log/disk.deny
cobbler import --path=/data/iso/CentOS-6.4-x86_64 --name=CentOS-6.4-x86_64 --kickstart=/data/iso/6u4_cobbler.ks

3.给cobbler添加主机 使用add_host.sh添加机器

[root@hj iso]# cat add_host.sh
while read hostname profile eth0_mac eth0_ip ilo_user ilo_pass ilo_ip eth1_mac eth1_ip eth1_mask gw
do
  cobbler system add --name=$hostname --hostname=$hostname --profile=$profile --kopts="nousb noapic acpi=off" --interface=eth0 --mac-address=$eth0_mac --ip-address=$eth0_ip --netmask=255.255.255.0 --static=1 --power-type=ipmilan --power-user=$ilo_user --power-pass=$ilo_pass --power-address=$ilo_ip
  cobbler system edit --name=$hostname --interface=eth1 --mac-address=$eth1_mac --ip-address=$eth1_ip --netmask=$eth1_mask --gateway=$gw --static=1
done<add_host.list

add_host.list格式：

#hostname profile eth0_mac eth0_ip ilo_user ilo_pass ilo_ip eth1_mac eth1_ip eth1_mask gw

附属：利用pssh收集主机的设备信息：cobbler_host_list.sh

#!/bin/bash
host=$(hostname)
eth0_ip=`ifconfig |grep eth0 -A1 |grep "inet addr:" |awk '{print $2}' |awk -F: '{print $2}'`
if [ -z $eth0_ip ];then
    eth0_ip=`ifconfig |grep em1 -A1 |grep "inet addr:" |awk '{print $2}' |awk -F: '{print $2}'`
fi
eth0_mac=`ifconfig |grep eth0 |awk '{print $NF}'`
if [ -z $eth0_mac ];then
    eth1_mac=`ifconfig |grep em1 |awk '{print $NF}'`
fi
eth1_ip=`ifconfig |grep eth1 -A1 |grep "inet addr:" |awk '{print $2}' |awk -F: '{print $2}'`

    eth1_mac=`ifconfig |grep em2 |awk '{print $NF}'`
fi
eth1_mask=`ifconfig |grep eth1 -A1 |grep "inet addr:" |awk '{print $4}' |awk -F: '{print $2}'`
if [ -z $eth1_mask ];then
    eth1_mask=`ifconfig |grep em2 -A1 |grep "inet addr:" |awk '{print $4}' |awk -F: '{print $2}'`
fi
gw=`route -n|awk '/UG/ {print $2}'`
profile="CentOS-6.2-x86_64"
ilo_user="root"
ilo_pass="XXXX"
ilo_ip=`echo "$eth0_ip" | awk -F. '{ip=2} END { print $1"."$2"."ip"."$4}'`
echo -e "$host $profile $eth0_mac $eth0_ip $ilo_user $ilo_pass $ilo_ip $eth1_mac $eth1_ip $eth1_mask $gw"
