 Posted: Sat Jan 03, 2015 2:50 am Post subject: Install script for Gentoo |
 |
|
I got tired of reinstall manually, so broke down and wrote a script.
I hope others can use it, here is Gentoo_Install followed by Continue and Instruction that I used to install Gentoo.
Let me know if you like it, by posing here.
| Code: | #!/bin/bash
# This program installs Gentoo 2014 & Newer.
# Remember This wipes out the entire Hard Drive.
# Make sure this is what you want to do !!!!!!!!!!

To use Gentoo Install script.
Please note that this will destroy all information on that hard drive!!!!!! Make sure you don’t want or have it backed up before you start.
I made a USB* stick with either ext2 or ext4 format. I use the CD-ROM since I could not get a USB to install and have the scripts on the same USB, if someone gets this to work please post here of others.
Make CD-ROM of Gentoo minimum, as instructed by Gentoo.
Now startup computer and use CD-ROM
When you get:
livecd ~ #
type in command passwd & fill in password you want for root.
Then type in command /etc/init.d/sshd start to start SSH server.
Then I type in command ifconfig to get the IP address of that machine.
Then optionally you can at this point use another machine and remotely login at this point.
I go to my windows machine with PuTTY and login, with root and the password I set earlier.
Now I mount the above USB using command mount /dev/sdb1 /mnt/key.
On the windows machine I use note and open up the script (Continue) and use “select all“ then “copy”. Got to PuTTY and open my favorite editor in my case nano /mnt/key/Continue and right click, so that the info is pasted in the file, and then save.
Then do same way with Gentoo_Install.
The make executable with command chmod +x /mnt/key/*
Then run script /mnt/key/./Gentoo_Install and fill in questions as they appear. This allows you the choice of Manually building the kernel or Automatically. If you want to skip this step & run Automatic build of the kernel you may run /mnt/key/./ Gentoo_Install a.
If you want desktop or other services you can add them later.
Estimated time to completion is a little over 2 hours. My best using genkenel all is 1 hr 55 min.
If you don’t want to reboot you can when it says that it will reboot in 15 seconds hit Control C (Ctrl C), or remove the reboot line in Gentoo_Install by placing # in front of reboot at the end of the file.
*To make a USB stick this will destroy all information on the stick!!!!
After you have the:
livecd ~ #
type in fdisk /dev/sdb
command p @ Command (m for help):
This will list partitions
You can then type in d for delete (return key) it will ask for number you can take the default, the hit d until all partitions are removed
Then type in n for new partition it will ask for start and end you can hit the return to take defaults for one partition.
Then type w to write and save.
mkfs.ext2 -F /dev/sdb1 to make a ext2 format or
mkfs.ext4 -F /dev/sdb1 to make a ext4 format
Note: this assumes that your USB is /dev/sdb if yours is different male adjustments.
|
If you have any suggestions for improvements (i.e. other languages) please make the changes and post your file(s) here. It is in bash so should be easy to change. If you were making language changes I would recommend renaming files with language at end (i.e. ISO 639-2 Code Gentoo_Install_ger and Continue_ger for German) so that those who want more than one language can have them all on same stick.
This should be good for anyone that uses US keyboard. |

| Why do you fake a /usr/bin/passwd prompt, storing the user input plaintext in exported variables, when you could achieve the same thing securely using `passwd -R`? |

MC_Gen,
American users only?
My timezone is Europe/London.
Your install will not boot on many BIOS systems. They tend to check that the MSDOS partition table has the boot flag set somewhere.
When you make a GPT disklabel, you also get a free MSDOS disklabel with a single partition, that describes as much of the disk as it can.
It has not got the bootable flag set, so BIOS systems may refuse to load the boot loader.
You need an fdisk -t msdos /dev/sda ... and set the bootable flag.
| Code: | #Make sure that you remove all data
parted -s /dev/sda -- mkpart primary 1 -1
parted -s /dev/sda mklabel msdos
mkfs.vfat /dev/sda1
parted -s /dev/sda rm 1 |
Does not remove all the data. mkfs.vfat creates the FAT data structures and root directory at the start of the disk, overwriting what used to occupy that space. Everything else is still intact, including the backup GPT, if the disk was GPT.
As you are going with GPT for the new install, there is no need to trash the existing MSDOS disk label, if there is one.
To trash the data, you need shred or DBAN, neither are fast. You could make it a user option.

Put System Rescue CD on a USB stick. Add scripts.
You will need to mount the USB stick in see the scripts as root is a looback mounted file on the USB, so your scripts are outsite the rootfs.
You can also modify the System Rescue CD looback mounted file.
There is another way, used by the liveDVD when its on a USB stick. It uses an overlay filesystem to make a read only filesystem appear to be writable.
It has a 'persistant' option.
| Code: | if [ `uname -m` == 'x86_64' ]; then
# 64-bit stuff
...
else
# 32-bit stuff |
is a bit simplistic.
gets me an i686 stage 3 to install on my Raspberry Pi.
I'm teasing a little just now. Scripts like this can be a good thing for users that know what they are doing but they deprive novices of the learning experience of installing Gentoo that they will need to maintain it, once its full of their valuable data.

Too many timezones for every one (13 for US). That is why there should be separate file for each area, and keyboard. etc. I could have stacked case statements, but that was more work than I was up at this time. It may change in the future.

I was trying to format so that all data was erased, not good practice, but it worked when I was not rebooting.
Grate idea for USB stick!

Sorry it is meant as a tool so that those who have to repetitively install can reduce the errors from a lot of typing. Thought those who have to install many units, they can start one let it finish inputting data and let it compile & start a new unit, for example.
Have worked with Ward Mundy on scripts for installing his version FreePBX called Incredible PBX. He is at http://nerdvittles.com/ if anyone wants to look at. I wrote the first script that he modified for use in his Incredible PBX. I was seeing if I could install Asterisk. Not looking good at this point, but keep plugging along. |

MC_Gen,
Removing the partition table(s) removes pointers to data, not the data itself.
You can access the data without using the partition table, if you know where the filesystems start, testdisk will tell you, if you need to ask.
See the offset= option to mount.
Timezone and keyboard layout choice has been done many times before. Why not build on the work of others?
e.g. How does System Rescue CD do it at boot?
That's what GPL, CC (some of them) and FOSS is all about.
I suspect its easier to parse the content of /usr/share/zoneinfo than to write a huge case statement that you need to maintain as timezones are added and removed.
I don't do bash, so thats a systems engineering solution to the problem, not a working prototype.
Likewise, for keyboards. Then I can have my dvorak-uk.
Given the aim of installing many identical (similar?) units, you soon get tired of visiting them all with a screen, keyboard, display and USB stick.
You PXE boot them for the install and ssh in to make final adjustments. Your script could still be used but it needs to take its input from a file.
I guess that can be arranged with bash redirection.

There is also a way to figure time zone by IP address as Ubuntu does it for you. Will take some time

If I were going to use PXE I would hard code screen, keyboard and timezone.
It is a first draft. I have tried to document as I went along so that those who want to work on it should be able to follow.
Bash/SH is not that hard, most of it is inputting the commands like you do at the keyboard. It is the easiest of the scripting in my opinion. It has solved a lot of problems for me.
As in Flesh Gordon "Monster's work is never done."

MC_Gen,
I wasn't trying to detract from your work. Just save you from reinvesting the wheel.
Keep up the good work.
