    • How to Install ArchLinux on a USB Flashdrive in 2012 – For Newbies Only! By: Chukwuma I. Onyeije, M.D. (linuxonyeije at onyeije dot net)I recently started using Archlinux as my secondary Linux operating system and I have been very impressed by it’s speed, versatility and minimalist philosophy.Another thing I’ve been very impressed with is the fact that I can install the system on a USB Flashdrive and boot into a fully functional Linux environment with persistence.Unfortunately, much of the information regarding how to create ArchLinux does not cover a USB Drive install and some of the information out there refers to an older version of ArchLinux with slightly different menu options or is too cursory for a new user. PAGE 1 of 9
    • Therefore; I am making available a tutorial based on my personal method for creating an ArchLinux installation on a USB Flashdrive 2012.WARNING: This tutorial is a bare bones description of the process to create an ArchLinux installation for USB. Although suitable for Newbies (like myself) the person doing this should have a fair amount of familiarity with Linux, the command line and the Archlinux installation process.ACKNOWLEDGEMENTS:In order to create this tutorial I have borrowed heavily from the followingsources (and without whom I would have NEVER been able to do this):Build a Killer Customized Arch Linux Installation (and Learn All About Linux in theProcess by Whitson Gordon:http://lifehacker.com/5680453/build-a-killer-customized-arch-linux-installation-and-learn-all-about-linux-in-the-processHow-To Install Archlinux on a USB Stick and boot from it! By PlatinumMonkeyover at USA Linux Users Group.http://usalug.com/phpBB3//viewtopic.php?t=12377Installing Arch Linux on a USB key over at the ArchLinux Wiki:https://wiki.archlinux.org/index.php/Installing_Arch_Linux_on_a_USB_key1. Obtain a cheap USB key with enough space. I was able to purchase an 8 GB USB drive made by Patriot Memory for $5.95 at a local electronics store2. Obtain the Arch Linux CD and burn the iso unto DVD. On my Ubuntu machine I use Brasero. http://www.youtube.com/watch?v=KKdIco-3nvo3. If you are using a Windows PC I would recommend Infracorder... http://infrarecorder.org/4. When I first created an ArchLinux USB drive I deleted all partitions on the USB drive with Gparted and created a single primary partition using FAT32 format.5. Alternatively, you can delete any existing parition(s) and create a new Primary partition using the Linux type (83) within cfdisk. Please Note: One of the times PAGE 2 of 9
    • I tried this it failed miserably. I recommend starting with a clean USB that has been repartitioned with Gparted.6. Boot the ArchLinux CD and launch AIF with (you will be instructed to do this on the opening screen of the ArchLinux CD) /arch/setup7. Follow the steps for a normal Archlinux CD setup.PARTITION THE USB DRIVE WITH cfdisk: • In the main menu select Prepare Hard Drive and select your USB • Please note that the USB flashdrive will likely be given a name like /dev/sdb and your hard drive on your computer will likely be /dev/sda.8. When given the option of how to prepare your drive, choose "Parition Hard Drive" which will run cfdisk on the device your flashdrive9. Make the partition bootable.10. Make the FS Type Linux. (**** If cfdisk defaults to Linux type 82... Change it to Linux type 83)11. Leave space for a logical partition on the USB. I used about 512 MB.12. I partitioned this extra space logical partition as W95 FAT3213. Write these changes to the USB and exit.14. Select “Manually Configure block devices, filesystems and mountpoints”15. Select the UUID option16. Select /dev/sdb117. Select YES when asked to Recreate file system18. Select Ext4 for /dev/sdb119. Select / (root) as the mount point20. Give the newly created mount point a label. I chose “arch”21. Select the other partition on /dev/sdb (this will be something like /dev/sdb2 or /dev/sdb5 or similar…)22. Select YES when asked to recreate it’s file system23. Select Ext2 for /dev/sdb524. Select custom mountpoint PAGE 3 of 9
    • 25. When asked: “Enter custom mountpoint for /dev/sdb5 – insert a short label. 26. Allow the default option for all other questions 27. Ignore the warning that says No separate /boot filesystem and no swap partition defined. 28. Select Packages 29. Select GRUB 30. Select “Configure system” from the Main Menu.SELECT CONFIGURE SYSTEM FROM THE MAIN MENU: 31. Select: /etc/rc.conf: • Scroll down to the NETWORKING section set your HOSTNAME to whatever you want, • Add eth0 to your so the line would read INTERFACES=eth0 32. Select: /etc/hosts: Make sure your computers hostname matches the one you picked in /etc/rc.conf (which it should have done automatically) 33. Select: /etc/fstab: • Make sure fstab contains the /dev/sdb of the partitions from your USB drive. 34. Select: /etc/mkinitcpio.conf: • At the bottom of this file add “ide usb” after base and before udev. 35. Select /etc/pacman.conf: • By default you are given three repositories: [core], [extra], and [community]. • If youre on a 64-bit system, you should edit /etc/pacman.conf and uncomment the [multilib] line and the line below it, near the bottom of the file. This will add the [multilib] repository to your setup, which contains 32-bit applications for those situations in which you need them. 36. Select /etc/pacman.d/mirrorlist: PAGE 4 of 9
    • • Uncomment mirrors that are near you.37. Select: "Root-Password" to set the password for the root account, then scroll down to "Done" and press Enter.38. It will run through a few processes to configure your system and return you to the main menu.Select INSTALL BOOTLOADER: • THIS IS IMPORTANT: • You will be prompted to edit the menu.lst config file. • Edit root to be set as “hd0,0”39. Install the bootloader to the MBR for your USB drive (ie, /dev/sdb)40. Exit Install.41. Type “reboot “ at the command prompt.42. If everything went well you should be greeted by a login prompt.43. Update system with pacman: pacman –Syu44. If necessary, edit your mirrorlist with nano /etc/pacman.d/mirrorlist45. ADD YOURSELF AS A USER: • To do so, just run the following command: useradd -m -g users -G audio,lp,optical,storage,video,wheel,games,power -s /bin/bash YOURNAMEHERE46. Replace YOURNAMEHERE with your desired username. The long string of comma-separated terms contains the groups to which your user belongs.47. Next, add a password for your new user by running: PAGE 5 of 9
    • passwd YOURNAMEHERE and typing in your desired password when prompted. 48. QUICK (BUT DIRTY) ALTERNATIVE:Use the command adduser to add a user and a password. 49. Install sudo with: pacman -S sudo 50. Once youve installed Sudo, youll want to add your user as a valid sudoer. Youll need to use the special command visudo to do this, which uses the editor vi to edit /etc/sudoers. Unfortunately, vi is not very friendly if you dont know how to use it, so for now well change visudos default editor to our friend nano by running it with the EDITOR variable, like this: EDITOR=nano visudo 51. You can use many strategies to add your user as a sudoer, but were going to just tell Arch to let all users in the group "wheel" use sudo. So, uncomment this line in/etc/sudoers: %wheel ALL=(ALL) ALL 52. When youre done, you can move on to configuring video and sound.INSTALL ALSA 53. Before installing ALSA, youll want to edit your /etc/modprobe.d/modprobe.conf file by typing nano /etc/modprobe.d/modprobe.conf at the command prompt. Add the following line to the file: options snd-pcsp index=2 PAGE 6 of 9
    • 54. This will make sure the snd-pcsp module load last, ensuring that your sound will work correctly.55. Then, install alsa-utils with Pacman. You should know how to do this by now, but for good measure, the command is pacman -S alsa-utils. However, youll also probably want alsa-oss. You can actually install them both in one fell swoop with: pacman -S alsa-utils alsa-oss56. Next, youll want to start up alsamixer as a normal user (not as root). To do so, type su - yourusername and then enter: alsamixer57. Make sure the correct channels are unmuted (usually Master and PCM, though you may need to turn up others like Front Speaker or Headphone). Usually, youll want to raise their volume all the way up, but make sure under "Item" at the top there is not a positive number next to "dB gain". If there is, turn the channel down until "dB gain" is zero.58. Exit alsamixer with Esc and check if your sound is working correctly by typing in the following command: aplay /usr/share/sounds/alsa/Front_Center.wav59. If you hear a womans voice, your sound works correctly. If not, go back and make sure the right channels are unmuted.60. Switch back to the root user by running su and type in: alsactl store to store these values.61. To make your computer call on these settings at boot, edit /etc/rc.conf in nano and add alsa to the DAEMONS section: PAGE 7 of 9
    • DAEMONS=(syslog-ng network netfs crond alsa)INSTALL X62. Install Xorg with the following command: pacman -S xorg-server xorg-xinit xorg-utils xorg- server-utils xorg-twm xorg-xclock xterm63. You can also include the package mesa if you foresee yourself using 3D graphics.INSTALL VIDEO DRIVERS: 64. You will need knowledge of which video chipset your machine has. If you do not know, use the /usr/sbin/lspci program: $ lspci | grep VGA 65. For a complete list of all open-source video drivers, search the package database: $ pacman -Ss xf86-video | less 66. Use pacman to install the appropriate video driver for your video card/onboard video. Example for the Vesa driver # pacman -S xf86-video-vesa 67. Before testing X, youll also want to fetch xf86-input-keyboard and xf86-input-mouse with Pacman pacman -S xf86-input-keyboard xf86-input-mouse 68. If youre on a laptop, youll want xf86-input-synaptics as well. 69. Try starting X with: startx PAGE 8 of 9
    • 70. If it works, you should be able to interact with a very basic windowed environment and run commands in xterm.71. Exit by typing exit into xterm and hitting Enter PAGE 9 of 9
