ok, so do you simply rsync the repositories from the other distributions
you need?



I forgot to mention: before mirroring using higher tier repository: contact their admin, ask if they do not mind that you will mirror using them as a higher tier mirror, and tell them all details: public/private mirror, your bandwidth, how often you plan to run sync - and ask them what frequency of sync is OK with them.

After you roll out and know all works, if your plan is public mirror, next step will be to register your mirror.

All in all, every distribution has HOWTO instruction to become their mirror, follow these.

And as always, use web search to find these instructions: duckduckgo is your friend.

Short answer: yes.

Long answer:
Every repository has its own suggestion how to mirror. I do not have Debian mirror, my friend sysadmin in the next building maintains one, no need for two in the same institution. Here in my cron job script for mirroring CentOS (with some local details obfuscated):

#==============
#!/usr/local/bin/bash
# We use locks...

touch=/usr/bin/touch
echo=/bin/echo
ps=/bin/ps
cat=/bin/cat
grep=/usr/bin/grep
wc=/usr/bin/wc
rm=/bin/rm
sendmail=/usr/sbin/sendmail
date=/bin/date
rsync=/usr/local/bin/rsync
# DEFAULTS
ADDR=recipient@server
FROM=sender@hostingmirror
lockfile=/.../lock/centosmirror.lock
mirror=/.../mirror/centos
logfile=/.../mirrorlog/centos.log

# check if log file exists, and create if not

if [ ! -f $logfile ]; then
$touch $logfile
fi

# check if lock exists, then bale out sending warning,
# otherwise rsync

if [ -f $lockfile ]; then

# check if the process resembling lock still exists,
# if not, just delete lock

if [ "$($ps -p `$cat $lockfile` | $wc -l)" -gt 1 ]; then

# Send the message
(
$echo "From: $FROM"
$echo "To: $ADDR"
$echo "Subject: CentOS mirror failed"
$echo ""
$echo "CentOS mirror process bailed out as there is another process"
$echo "with the same name and the following PID:"
$echo ""
$echo "`$cat $lockfile`"
echo ""
echo "You may want to check logs:"
echo ""
echo "/.../mirrorlog/centos.log"
) | $sendmail -F $ADDR -t

else

# no process, just delete the lock, and mirror

$rm -f $lockfile

$echo $$ > $lockfile
$echo "`$date`  started mirroring" >> $logfile
$rsync -aqH --exclude .~tmp~/ --exclude .~tmp~ --delete us-msync.centos.org::CentOS /data/mirror/centos
$echo "`$date`  finished mirroring" >> $logfile
$rm $lockfile

fi

else

$echo $$ > $lockfile
$echo "`$date`  started mirroring" >> $logfile
$rsync -aqH --exclude .~tmp~/ --exclude .~tmp~ --delete us-msync.centos.org::CentOS /data/mirror/centos
$echo "`$date`  finished mirroring" >> $logfile
$rm $lockfile

fi

Pulp is a bit overkill for my liking.


Coming back to the original question: mirror hosting variety of
distributions, does not have to have any packaging or other tools used by
those distributions. Public mirror box I support runs FreeBSD, and hosts
mirrors of CentOS, Ubuntu, CPAN, EPEL, …

I hope, this helps.

Hello,

Is Pulp not supposed to do what you want : RPM, DEB and more in the same
software ?

I'm not using Pulp, just reading their website.

Thank you. This at least point me in the right direction. I don't quite
want to setup 2 servers, or 2 VM's for this.

Hi,

Does anyone have some instructions on setting up a CentOS server as
mirror
for Debian and Ubuntu distributions? I already setup a YUM mirror and
this
works fairly well, but cannot seem to figure out how to mirror Debian
and
Ubuntu repositories.

You need to grab a copy of debmirror, which is just a Perl script, so
it
should work under CentOS. I don't know where to get a version as a
tarball
--
I had an available VM running Ubuntu and just installed it there and
NFS
mounted the mirror disk from the CentOS server. There is a config file
for
debmirror to control where you mirror from and just what you mirror
(versions,
arches, etc.). There is a man page and and example config file.  You
then
run
debmirror from crontab (eg every day).

Unfortunately, the Debian flavor repositories are not structured to
just
be
rsync'ed like the CentOS repositories.
