Been building a new mirror (internal) host @ work, and its been an adventure. This isn’t a public mirror, and we’re not interested in mirroring all releases of Distro X, but rather only a handful or one. We basically want to mirror:
- CentOS 5 & 6
- EPEL 5 & 6
- PuppetLabs Repos for el5 & 6
- Ubuntu LTS Release(s)
Now, the mirror box is a Centos6 host, so this is pretty simple when it comes to the CentOS mirrors, thats comeing in another post. We do some funky things like want a fully sync’d mirror, but also want point-in-time snapshots so we have a static source to build compute nodes from (while storeage/webserver get the up-to-date repos).
In anycaase, building a Ubuntu mirror, other than just rsync'ing archive.ubuntu.com/ubuntu, on a non-Ubuntu/Debian host is non-trival it seems, just like using something other than rsync to mirror yum repos on something w/o yum installed would be awkward. However, I’ve found a solution:
DebMirros is really just a Perl script, and I’m wrapped it up in script for our setup. Took a little bit to get going, though:
yum install perl-libwww perl-Compress-Zlib perl-Digest-SHA1 perl-Net* rsync perl-LockFile-Simple perl-Digest-MD5-M4p wget http://archive.ubuntu.com/ubuntu/pool/universe/d/debmirror/debmirror_2.10ubuntu1.tar.gz tar -xzvf debmirror_2.10ubuntu1.tar.gz ... cd debmirror-2.10ubuntu1 make cp debmirror /usr/local/bin/ cp debmirror.1 /usr/share/man/man1/ cpan install Net::INET6Glue (couldn't find this in yum).
Okay, debmirror now works, but needs that wrapper script:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22
Make that executable, run it, and we’re off! First sync is running now. Next up is to see how quickly a resync happens, and schedule it to run daily. Hello internal Ubuntu Mirror!
The really nice thing is when the next LTS comes out (Precise Pangolin), I can simple add it to the list of release like release=lucid,precise And we’ll start mirroring that!
