Software Repository Mirror
This has been adapted from these instructions. You will need a 200GB external hard drive that you can reformat.
WARNING: This has not been fully tested. Please correct or send feedback to "litlfred@ibiblio.org"
Preparing the Hard Drive
In the directions below we will assume that you have a brand new hard drive. We will be formatting the hard drive (partition) which means that all of the data on the hard drive will be lost. PLEASE MAKE SURE YOU KNOW EXACTLY WHAT YOU ARE DOING IN EACH STEP
To format the partition, we will first need to set the partition type
Determining the Hard Drive Paritition
To format the hard drive, we first to know what "partition" it is using. Ubuntu should automatically mount the hard drive should automatically once you plug it in. To determine run the command:
mount | grep media
Running this on my machine, I see output
/dev/sdb1 on /media/3539-6663 type vfat (rw,nosuid,nodev,uid=1000,gid=1000,shortname=mixed,dmask=0077,utf8=1,showexec,flush,uhelper=udisks)
Which means the /dev/sdb1 is the partition we will need to use.
If you see more than one line in the output then STOP as these directions may not be correct. If you see more than one line here, you probably have more than one external hard drive or flash disk connected. Remove all extra hard drive and rerun the "grep" command. If you still see more than one line, Please contact one of the of the iHRIS developers for more help.
Change The Hard Drive Partition Type
We will need to run the "fdisk" command interactively on the hard drive device. If the parition was /dev/sdb1, the hard drive device is /dev/sdb (remove the number from the partition). Here is a sample interaction. You should type in everything in bold (changing /dev/sdb as neeeded):
litlfred@cumin:/tmp$ sudo fdisk /dev/sdb Command (m for help): p Disk /dev/sdb: 1015 MB, 1015808000 bytes 13 heads, 36 sectors/track, 4239 cylinders, total 1984000 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x0008db47 Device Boot Start End Blocks Id System /dev/sdb1 2048 1983999 990976 6 FAT16 Command (m for help): t Selected partition 1 Hex code (type L to list codes): 83 Changed system type of partition 1 to 83 (Linux) Command (m for help): p Disk /dev/sdb: 1015 MB, 1015808000 bytes 13 heads, 36 sectors/track, 4239 cylinders, total 1984000 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x0008db47 Device Boot Start End Blocks Id System /dev/sdb1 2048 1983999 990976 83 Linux Command (m for help): w The partition table has been altered! Calling ioctl() to re-read partition table. WARNING: If you have created or modified any DOS 6.x partitions, please see the fdisk manual page for additional information. Syncing disks.
Formatting The Hard Drive as ext3
Simply do:
sudo mkfs.ext3 /dev/sdb1
Labelling the hard drive
Now we want to make a lablel for our newly formatted hard drive so that we can refer to it easily later:
sudo tune2fs -L ihris /dev/sdb1
Testing
Unplug the hard drive and plug it back in. There should be a USB disk icon on your Desktop with the label "ihris". Also, running:
mount | grep media
you should see somethine like:
/dev/sdc1 on /media/ihris type ext3 (rw,nosuid,nodev,uhelper=udisks)
Don't worry if your partition has changed from /dev/sdb1 to something else like /dev/sdc1
Creating the Software Repository
You should now have you hard drive prepared and mounted under /media/ihris. If not STOP
Mirroring
We will be mirroring (which means to create an identical copy of) the online Ubuntu repositories and the iHRIS PPA on Launchpad. All of the packages for Ubuntu and iHRIS will be saved into a subdirectories of our hard drive which we create with:
sudo mkdir -p /media/ihris/ubunruMirror/mirror sudo mkdir -p /media/ihris/ubunruMirror/mirroriHRIS
We will also need to install the debmirror software:
sudo apt-get install debmirror
mirrorbuild.sh
Save the script below to /media/ihris/ubuntuMirror/mirrorbuild.sh by copying and pasting with gedit:
sudo gedit /media/ihris/ubuntuMirror/mirrorbuild.sh
This is what you should copy and paste <source lang='bash'>
- !/bin/bash
- Setting variables with explanations.
basePath="/media/ihris/ubuntuMirror/"
- Don't touch the user's keyring, have our own instead
export GNUPGHOME=${basePath}keyring
- Outpath= # Directory to store the mirror in
outPath=${basePath}mirror
- Minimum Ubuntu system requires main, restricted
- Section= -s # Section (One of the following - main/restricted/universe/multiverse).
section=main,restricted,universe
- Release of the system (Dapper, Edgy, Feisty, Gutsy), and the -updates and -security ( -backports can be added if desired)
release=oneiric,oneiric-updates,oneiric-security,precise,precise-updates,precise-security
- You can change this to a faster/closer mirror if you wish
server=us.archive.ubuntu.com
- start the mirror of iHRIS packages on launchpad ppa http://ppa.launchpad.net/intrahealth+informatics/ihris/ubuntu
debmirror -a i386,amd64 --no-source -s main -h ppa.launchpad.net -r intrahealth+informatics/ihris/ubuntu -d natty --progress -e http ${outPath}iHRIS
- start the mirroring of ubuntu
debmirror -a i386,amd64 --no-source -s $section -h $server -d $release --progress -e http $outPath
</source> Note, when Ubuntu 12.04 (LTS Precise) is soon released, you should comment out the line about the release in the above section.
Trusting the Ubuntu Archives
We need to create a directory for our key ring and up our mirroring software to trust all of Ubuntu's software archives. This can be done with:
sudo mkdir -p /media/ihris/ubunruMirror/keyring sudo chmod 700 /media/ihris/ubuntuMirror/keyring sudo gpg --keyring /usr/share/keyrings/ubuntu-archive-keyring.gpg --export --homedir /media/ihris/ubuntuMirror/keyring/ \ | sudo gpg --no-default-keyring --keyring trustedkeys.gpg --import --homedir /media/ihris/ubuntuMirror/keyring/
Trusting the iHRIS Launchpad PPA
To trust the iHRIS PPA on Launchpad we do:
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 6EC21546 sudo gpg --keyring /etc/apt/trusted.gpg --export 6EC21546 --homedir /media/ihris/ubuntuMirror/keyring/ \ | sudo gpg --no-default-keyring --keyring trustedkeys.gpg --import --homedir /media/ihris/ubuntuMirror/keyring/
sources.list
The file /etc/apt/sources.list tells apt-get where to look for software packages to install.
We will want to have two versions of the sources.list file. One that will use the hard drive (sources.list.harddrive) and one that will use the internet (sources.list.internet). You will need to create a file /etc/apt/sources.list.harddrive
sources.list.internet
The default ubuntu installation assumes that you are connected to the interent. So we will simply copy the existing /etc/apt/sources.list to sources.list.internet
sudo cp /etc/apt/sources.list /etc/apt/sources.list.internet
sources.list.hardrive
We now need to create a version of the sources.list that will use the hard drive.
echo "deb file:///media/ihris/ubuntuMirror/mirror" `lsb_release -cs` "main universe " | sudo tee /etc/apt/sources.list.harddrive echo "deb file:///media/ihris/ubuntuMirror/mirroriHRIS natty main " | sudo tee -a /etc/apt/sources.list.harddrive
This will only work for Oneiric (11.10) and Precise (12.04)
Downloading the Software Repository
You can now simply use the command
sudo sh /media/iHRIS/ubuntuMirror/mirrorbuild.sh
This is the same command that you can use to update your mirror.
Using the Software Repository
source.list.hardrive as sources.list
Did you copy the /etc/apt/sources.list to /etc/apt/sources.list.internet as described above? If not STOP Let's switch to use the hard drive
sudo cp /etc/apt/sources.list.harddrive /etc/apt/sources.list
Installing Software
First we refresh the list of available packages that apt-get knows about
sudo apt-get -o Dir::Etc::sourceparts="blah" update
Now we can install package XXXXX from our hard drive by:
sudo apt-get -o Dir::Etc::sourceparts="blah" install XXXXX
source.list.internet as sources.list
Now that we are done, we should restore our original /etc/apt/sources.list
sudo cp /etc/apt/sources.list.internet /etc/apt/sources.list
