Customizing SysRescCD for use with XS School Server
There are several things you can do to customize [| SysRescCD] for use with an XS School Server.
- Configure the static IP addresses
- Configure the ethernet ports to specific MAC addresses
- Define userids to be used with SSHD
- Have ssh public keys to allow remote administration
- Include backup or rescue files
Download and Burn original SysRescCD
The easiest way to do this is to perform "wget" for the iso file. I had to update my resolv.conf to a DNS nameserver I could access, and then do a wget for the URL involved. The file is about 200MB and took me about 11 minutes to download on my system.
[root ~]# echo "nameserver 205.171.3.65" >> /etc/resolv.conf [root ~]# wget -c http://downloads.sourceforge.net/systemrescuecd/systemerscuecd-x86-1.0.3.iso ... systemrescuecd-x86-1.0.3.iso saved... [root ~]# cdrecord -scanbus scsibus6: 6,0,0 600) 'ATAPI ' 'DVD A DH20A4H ' 'QP53' Removable CD-ROM [root ~]# cdrecord dev=6,0,0 -v systemerscuecd-x86-1.0.3.iso
Unpack the files
Boot from the SysRescueCD you just made, and hit enter at the "boot: " command prompt. We are basically going to open up the CD, and put all the files on our hard-drive. I will use /dev/sda3 as an example.
[root@sysresccd /root] % mount /dev/sda3 /mnt/custom [root@sysresccd /root] % /usr/sbin/sysresccd-custom extract /mnt/custom is mounted -> ok there is enough estimated free space here (25548 MB) -> ok docache not used -> ok [root@sysresccd /root] % cd /mnt/custom/customcd [root@sysresccd /mnt/custom/customcd] % ls files isoroot [root@sysresccd /mnt/custom/customcd] % cd isoroot [root@sysresccd /mnt/custom/customcd/isoroot] % ls bootdisk isolinux syslinux version [root@sysresccd /mnt/custom/customcd/isoroot] % cd isolinux [root@sysresccd /mnt/custom/customcd/isoroot/isolinux] % ls altker32 f1boot.msg f4arun.msg f7net.msg isolinux.cfg memtest86 altker64 f2images.msg f5troubl.msg initram.igz maps rescue64 boot.cat f3params.msg f6pxe.msg isolinux.bin memdisk rescuecd
If you will updating the "initram.igz", you will have to further unpack that as follows:
[root@sysresccd /mnt/custom/customcd/isoroot/isolinux] % gunzip -c initram.igz > initram.img [root@sysresccd /mnt/custom/customcd/isoroot/isolinux] % mkdir work [root@sysresccd /mnt/custom/customcd/isoroot/isolinux] % cd work [root@sysresccd /mnt/custom/customcd/isoroot/isolinux/work] % cpio -id < ../initram.img 36176 blocks [root@sysresccd /mnt/custom/customcd/isoroot/isolinux/work] % ls bin dev etc init lib lib64 linuxrc proc sbin sys temp usr var [root@sysresccd /mnt/custom/customcd/isoroot/isolinux/work] %
Create Additional Mount points =
root@sysresccd /mnt/custom/customcd % cd files root@sysresccd /mnt/custom/customcd/files % ls bin dev home lib64 mnt proc sbin tftpboot usr boot etc lib media opt root sys tmp var root@sysresccd /mnt/custom/customcd/files % cd mnt root@sysresccd /mnt/custom/customcd/files/mnt % ls cdrom floppy root@sysresccd /mnt/custom/customcd/files/mnt % mkdir boot fed deb usbkey scratch new old source dest root@sysresccd /mnt/custom/customcd/files/mnt % ls boot cdrom deb dest fed floppy new old scratch source usbkey
