本人习惯通过cobbler部署物理机系统，那我就来说说部署系统前需要做哪些准备
1.BIOS设置是否符合标准。比如F1/F2错误提示、系统启动顺序、是否有开启PXE启动等。
2.你从哪个网卡进行pxe引导，cobbler部署需确定对应服务器网卡的MAC地址。
3.做磁盘阵列，此项是最耗费时间的。也是这个原因，才有了这个文档。
4.更改idrac root用户的密码，并新增一个组内通用用户。
一、racadm环境部署及文档说明
此文档仅适用于dell且配置了iDRAC远程管理卡的机器（主要是配置了idrac ip，方便远程连接）。全文脚本依赖于racadm环境，需在放置脚本的服务器上安装srvadmin包。
环境部署如下：
# wget http://downloads.dell.com/FOLDER03574555M/1/OM-MgmtStat-Dell-Web-LX-8.3.0-1908_A00.tar.gz -P /tmp/ # tar zxvf OM-MgmtStat-Dell-Web-LX-8.3.0-1908_A00.tar.gz # cd /tmp/linux/rac/RHEL6/x86_64/ # rpm -ivh srvadmin* # ln -s /opt/dell/srvadmin/bin/racadm /usr/bin/racadm
具体命令和用法，我就不说了，大家可以参考以下手册
二、 脚本说明
脚本部分一共包含三部分。
- hosts.conf文件：脚本从文本文件中获取ip信息，网卡号，需配置的阵列类型等。
- run.sh：运行脚本，此脚本从hosts.conf文件中获取信息并后台执行bin目录下的脚本，实现多机器并发。
- bin目录：此目录放置实现网卡获取、用户添加、raid配置等脚本。
1.hosts.conf文件内容，初步定义如下。
# NIC_NUM后的数字表示第几块网卡，电口用网口3或4进行PXE安装，光口用网口1或2进行PXE安装 # raid方式：[ RAID: no | RAID: 0 | RAID: 5 ] # RAID: 5:方式一：有2块500G左右盘做sda ,其余HDD做sdb; 方式二：所有HDD大小一样，划分300Ｇ做sda，剩下做sdb。两种方式都会判断是否有SSD) # idrac ip书写方式有两种：192.168.1.1-10或每一行写一个IDRAC IP NIC_NUM: 1 RAID: 5 192.168.1.1-10
2.run.sh脚本内容
