The existing server will likely be something like us. Replace the server name for the Ubuntu Archives with your local mirror. This mirror will be good for main, universe, multi-verse, and restricted. Now that you have your very own Ubuntu Mirror, you need to point all of your workstations and servers to this mirror for their updates. You should see some directories named 'dists', 'indices', 'pool', 'project', and a file named 'ls-lR.gz'. You can test to see if this was successful by using a web browser to visit the site. Assuming that you have Apache configured to follow symbolic links, all you need to do is add a symbolic link to your mirror! cd /var/www/ 15 21 * * * /usr/local/bin/sync-ubuntu-mirror.sh > /dev/null 2> /dev/null

#UBUNTU GRSYNC UPDATE#

This example sets the system to update every night at 9:15 PM. Insert the following line, observing your particular time requirements, into the cron table. Chances are, you want to update during hours when your bandwidth will be under-utilized: only once every day in the middle of the night. In the case of your site, this may not be necessary nor desired. Official Ubuntu Mirrors are recommended to update their mirrors every 6 hours. While we are waiting for the initial update, we can build our script to keep the mirror up to date.Ĭopy and paste the script from to '/usr/local/bin/sync_ubuntu_mirror.sh'. Be careful of this mathematical difference.īuilding the script to keep it up to date NOTE: rsync measures bandwidth in Bytes, not bits. This is normal behavior for a mirror this large. NOTE: Even with the -progress flag turned on, rsync may take a very long time before giving any output. If you want to see the progress of the download, you can add the -progress flag to the command. # rsync -a -bwlimit=128 rsync:///ubuntu /media/mirror/ubuntu We will limit it to 128 KiloBytes per second to keep our sanity during working hours. Now that we have our destination, start the rsync download.

#UBUNTU GRSYNC DOWNLOAD#

However, you will probably need to limit the speed of your download so it can download at a reduced speed for the next few days (weeks?).

#UBUNTU GRSYNC FULL#

If you can let the download run at full speed for the full gauntlet, more power to you.

mailx is only required if you want to have your script email you when something goes wrong.īecause we are downloading 600+ Gigabytes from the Internet this download will take a VERY long time.

rsync is required to build and maintain our mirror.

XFS has been very successful for the author of this document.įormat your partition, pick a mount point, and add the setup to your fstab.įor the purpose of this document, we will assume that the mount point is /media/mirror and that our archives will be in the folder /media/mirror/ubuntu. Picking a file system can be tricky and is a highly debated subject. In addition, using a large hard drive will help prevent against file fragmentation Using a partition 1 TB or larger is recommended. The amount of space taken up will probably increase as time, so allocating double the amount of space required should allow for adequate growth without needing a hardware upgrade.

#UBUNTU GRSYNC ARCHIVE#

An Ubuntu Server with ample storage (~1+ TB)Īs of September 2019, the Ubuntu Archive takes up approximately 1 TB of space.

The use of a mirror in these cases will reduce the amount of bandwidth required for these clients on your end of the link, but also the bandwidth required for Official Mirrors.

This document will cover the second option and get you on up to speed.Ī local mirror might be suggested for sites with 50 or more sites. As of this writing, my mirror contains hoary, breezy, dapper, edgy, and the packages for the new feisty. So, as more versions come online, the more you will ultimately have to support.

The problem is that because it does not discriminate, you have the full mirror.

Use rsync - The great thing about rsync is it will grab EVERY file that is in those archives.

This is useful because it allows a finer degree of control and works well with limited hard drive space. Use Debmirror - Debmirror will allow you to select which parts of the archive (dapper, edgy, edgy-security, etc) you want to mirror. There are two good ways (that I know of) to maintain an internal mirror without using a proxy or apt-cacher. Apt-cacher is a good way to do this without a massive installation, however, apt-cacher does not allow for much control over what is downloaded and when it is downloaded.īy maintaining an internal mirror, a site can control when updates are grabbed from the Internet.

Extra Credit: Become an Official MirrorĪ local mirror is useful for a site that has many Ubuntu Servers and Workstations.

Publish the mirror on the Apache server.
