通过Cobbler实现自动化安装FreeBSD

atkisc

1. 挂载FreeBSD镜像

1. mount -t iso9660 -o loop FreeBSD-8.3-RELEASE-amd64-disc1.iso  /mnt

复制代码

2. 导入镜像文件到Cobbler

1. cobbler import --name=FreeBSD-8.3 --arch=x86_64 --path=/mnt
   
2. 我们在导入过程中可能会提示TASK FAILED

复制代码

可以忽略

3. 修改loader.conf

1. echo vfs.root.mountfrom=\"ufs:/dev/md0\" >> /var/www/cobbler/ks_mirror/FreeBSD-8.3-x86_64/boot/loader.conf
   
2. echo vfs.root.mountfrom.options=\"rw\" >> /var/www/cobbler/ks_mirror/FreeBSD-8.3-x86_64/boot/loader.conf

复制代码

4. 挂载mfsroot.gz

1. 将/var/www/cobbler/ks_mirror/FreeBSD-8.3-x86_64/boot/mfsroot.gz拷贝到一台FreeBSD机器上后，执行如下命令
   
2. gzip -d mfsroot.gz
   
3. mdconfig -atvnode -f mfsroot
   
4. mount /dev/md0 /mnt

复制代码

5. 建立自动安装配置文件install.cfg

1. cd /mnt
   
2. cat > install.cfg < < EOF
   
3. debug=YES
   
4. nonInteractive=YES
   
5. noConfirm=YES
   
6. noWarn=YES
   
7. disk=mfid0
   
8. partition=all
   
9. bootManager=standard
   
10. diskPartitionEditor
    
11. mfid0s1-1=ufs 0 /
    
12. diskLabelEditor
    
13. tryDHCP=YES
    
14. netDev=bce0
    
15. hostname=tFreeBSD
    
16. distSetMinimum
    
17. nfs=1.1.1.1:/var/www/cobbler/ks_mirror/FreeBSD-8.3-x86_64
    
18. mediaSetNFS
    
19. installCommit
    
20. shutdown
    
21. EOF

复制代码

6. 将install.cfg合并到mfsroot

1. cd ~
   
2. umount /mnt
   
3. mdconfig -d -u0
   
4. gzip mfsroot
   
5. 再通过网络传输到Cobbler服务器覆盖原/var/www/cobbler/ks_mirror/FreeBSD-8.3-x86_64/boot/目录下的mfsroot.gz文件

复制代码

7. 安装配置nfs服务器

1. # 默认FreeBSD的网络引导程序pxeboot只支持nfs，如果想支持tftp需要自行重新编译这个程序
   
2. yum install -y nfs-utils
   
3. echo "/var/www/cobbler/ks_mirror/FreeBSD-8.3-x86_64 *(ro,root_squash)" > /etc/exports
   
4. /etc/init.d/rpcbind start
   
5. /etc/init.d/nfs start

复制代码

8. 更改Cobbler的dhcp模板文件dhcp.template

1. # ******************************************************************
   
2. # Cobbler managed dhcpd.conf file
   
3. #
   
4. # generated from cobbler dhcp.conf template ($date)
   
5. # Do NOT make changes to /etc/dhcpd.conf. Instead, make your changes
   
6. # in /etc/cobbler/dhcp.template, as /etc/dhcpd.conf will be
   
7. # overwritten.
   
8. #
   
9. # ******************************************************************

9. 同步Cobbler配置

1. cobbler sync

复制代码

现在就可以通过网络自动安装FreeBSD系统了
