Windows 7 IIS (HTTP Error 500.21 - Internal Server Error)解决

If you're in the FreeBSD world, you've probably already downloaded or csup'd FreeBSD 7.0 or are in the process of doing so now. As yes, after what seemed like waiting forever, the announcement of 7.0 went out last night.

I spent this morning making a DVD ISO of FreeBSD 7.0 to be included in the upcoming BSD magazine. Creating a DVD is easy and my instructions follow.

Start by downloading the following four files from your closest FreeBSD mirror; you'll find these files in the ISO-IMAGES-i386/7.0/ directory:

7.0-RELEASE-i386-disc1.iso
7.0-RELEASE-i386-disc2.iso
7.0-RELEASE-i386-disc3.iso
7.0-RELEASE-i386-docs.iso

Note: all of the mirrors are extremely busy today so you may haveto try a few before you find one close to you that has some connectionsleft. I saved mine to the download subdirectory of my home directory. Icreated a staging area, became the superuser and ran the followingcommands to mount and untar the contents of the 4 files:

cd ~dru/downloads/dvd-freebsd7/
mdconfig -a -t vnode -f ../7.0-RELEASE-i386-disc1.iso -u 0
mount -t cd9660 /dev/md0 /mnt
tar -C /mnt -cf - . | tar -xf -
umount /mnt

mdconfig -a -t vnode -f ../7.0-RELEASE-i386-disc2.iso -u 1
mount -t cd9660 /dev/md1 /mnt
tar -C /mnt -cf - . | tar -xf -
umount /mnt

mdconfig -a -t vnode -f ../7.0-RELEASE-i386-disc3.iso -u 2
mount -t cd9660 /dev/md2 /mnt
tar -C /mnt -cf - . | tar -xf -
umount /mnt

mdconfig -a -t vnode -f ../7.0-RELEASE-i386-docs.iso -u 3
mount -t cd9660 /dev/md3 /mnt
tar -C /mnt -cf - . | tar -xf -
umount /mnt


Next, use sed or the replace function of your favourite text editor to remove all incidences of ||1 and ||2 and ||3 from the file packages/INDEX.

Add these lines to cdrom.inf:

CD_VOLUME = 0
CD_VOLUME = 1
CD_VOLUME = 2
CD_VOLUME = 3

Then, remove this directory:

rm -Rf rr_moved

or you will get this error when you try to create your DVD:

mkisofs: Error: './rr_moved' and '(NULL POINTER)' have the same Rock Ridge name 'rr_moved'.
mki/usr/home/dlavigne6/sofs: Unable to sort directory


write failed: Input/output error

This command (type all on one line) will burn your DVD on the fly;note that it will NOT save a copy of the ISO to your hard disc:

growisofs -Z /dev/cd0 -J -R -no-emul-boot -b boot/cdboot -iso-level 3 .

To instead create an ISO which you can then burn at your leisure, use this command (typed all on one line):

mkisofs -V FreeBSD7 -J -R -b boot/cdboot -no-emul-boot -o freebsd7.iso .

and to burn the ISO:

growisofs -dvd-compat -Z /dev/cd0=freebsd7.iso

That's it. Have fun!本文出自 “枪炮与玫瑰的BLOG” 博客，请务必保留此出处http://axlrose.blog.51cto.com/434566/1293047
