Hello Everyone:
I'm new to Xen and have some Linux experience. I have installed Fedora
Core 6 on a Intel 3.2 GHZ machine. (Note: I have 1 machine to test
with.) I have 6GB of RAM. My ultimate goal is to install a few
versions of Fedora Core 3 on the box. (I have an old application that
uses FC3) I can start up the virt-install GUI with no problems. My
questions revolve around the location of FC3.
1. I know it can't be installed from a FC3 Install CD. <-- I don't
understand why this is not supported. It would seem to be the easiest
thing to do.
2. I know I can use NFS or HTTP.
3. I have Apache Web Server running and NFS is enabled.
Here are the questions
1. If I want to use http or NFS, do I copy the entire FC3 Install CD to
some place on the hard drive? Is the copy a *.iso file or is it the
individual files from the CD? This has never been clear for
me. I have seen conflicting information on the net about this
Either.
You can copy all files from each CD turn into a directory and share that via
NFS or HTTP (or FTP) for network installs. To copy the CDs, mount them one by
one,
run "cp -a /media/cdrom/* /wherever/you/want/it/", "umount /media/cdrom/", do
the same with the next CD and so on until they are all copied over. Make
sure to use the same destination directory for the cp command every time.
Substitute whatever path your CD/DVD drive mounts at for /media/cdrom/ if
that's not the right value.
I am sure this does not work well with the advent of yum repos on
install media. It's okay if you have a DVD image (there is only one),
but from CD there will be problems.
I've not yet see documentation, but I think a createrepo command will
fix it.
BUT, the files will be ro, so something like this would be the go:
find <newrepo> -type d -exec chmod 755 {} \;
find <newrepo> ! -type d -exec chmod 644 {} \;
Let's not have the xargs argument today, okay? Just to show I know, you
might also want this:
find <newrepo> -name TRANS.TBL -print0 \
| xargs -0 rm -f --no-run-if-empty
Also, there are (probably) some filenames duplicated*, so the original
cp might be
cp -f <etc>
The find ... xargs ... removes those I know about.
As of Red Hat Linux 7.2 (IIRC), which is a long time ago now, you can also
just place the .iso images of the CDs (or of the DVD) in a directory and do
NFS network installs (HTTP and FTP do not support this).
2. If I use http where do I put the files. (under /var/www/...??)
If you're not familiar with how to configure Apache, you should probably just
use NFS (it gives better performance anyway). The other option is to create
a subdirectory under /var/www/html/ (on Red Hat, /var/www/htdocs/
or /srv/www/htdocs/ on almost all other systems) on the web server computer
you want to use and then put the contents of the CDs in there
This is one way. I configure a virtual host for each distro, so each has
its own name space.
Placing the tree outside /var/www is possible, but selinux steps on your
toes.
3. I made a directory called /tmptest and copied the iso image to it.
I edited the /etc/exports file and added a line like this
/tmptest 192.168.107.14(rw,sync) <-- I assumed this means
I prefer not to litter the root directory; I generally use /var/local
(and sometimes have a whole disk there), others (I think) use /local
There is no reason to make it rw, use ro for something like this. It's
important security-wise.
I managed to delete lots that way once; I was using the then-new (but
not mine I hasten to add) script to create a rescue compact disk, and it
had to be run as root. There was a bug in it.... It's saner now.
192.168.107.14 has rw write access to /tmptest.
Try using:
/tmptest *(ro,sync)
The "192.168.107.14" in there would mean that that IP address would be the
only permitted client. Plus, if this is ro (which is important for
security), then there's no reason to limit which clients can connect to the
NFS server at the NFS server, unless you have troubles with people using your
install source and hogging bandwidth.
This seems to make
sense but the installation seems to always say invalid NFS source.
Any help would be greatly appreciated.
HTH.
