70 <title>The Gentoo Installation Approaches</title>
71 <subsection>
72 <title>Introduction</title>
73 <body>
74
75 <p>
76 Gentoo Linux can be installed using one of three <e>stage</e> tarball files.
77 A stage file is a tarball (compressed archive) that contains a minimal
78 environment.
79 </p>
80
81 <ul>
82 <li>
83 A stage1 file contains nothing more than a compiler, Portage (Gentoo's
84 software management system) and a couple of packages on which the compiler
85 or Portage depends.
86 </li>
87 <li>
88 A stage2 file contains a so-called bootstrapped system, a minimal
89 environment from which one can start building all other necessary
90 applications that make a Gentoo environment complete.
91 </li>
92 <li>
93 A stage3 file contains a prebuilt minimal system which is almost fully
94 deployable. It only lacks a few applications where you, the Gentoo user,
95 needs to choose which one you want to install.
96 </li>
97 </ul>
98
99 <p>
100 To help you decide what stage file you want to use, we have written down the
101 major advantages and disadvantages of each stage file.
102 </p>

105 </subsection>
106 <subsection>
107 <title>A Stage1 Approach</title>
108 <body>
109
110 <p>
111 A <e>stage1</e> is used when you want to bootstrap and build the entire system
112 from scratch.
113 </p>
114
115 <p>
116 Starting from a stage1 allows you to have total control over the
117 optimization settings and optional build-time functionality that is
118 initially enabled on your system. This makes <e>stage1</e> installs good for
119 power users who know what they are doing. It is also a great
120 installation method for those who would like to know more about the
121 inner workings of Gentoo Linux.

165 <title>A Stage2 Approach</title>
166 <body>
167
168 <p>
169 A <e>stage2</e> is used for building the entire system from a bootstrapped
170 "semi-compiled" state.
171 </p>
172
173 <p>
174 Stage2 installs allow you to skip the bootstrap process; doing this
175 is fine if you are happy with the optimization settings that we chose
176 for your particular stage2 tarball.

219 <title>A Stage3 Approach</title>
220 <body>
221
222 <p>
223 A <e>stage3</e> installation contains a basic Gentoo Linux system that has been
224 built for you. You will only need to build a few packages of which we can't
225 decide for you which one to choose.
226 </p>
227
228 <p>
229 Choosing to go with a stage3 allows for the fastest install of Gentoo
230 Linux, but also means that your base system will have the optimization
231 settings that we chose for you (which to be honest, are good settings
232 and were carefully chosen to enhance performance while maintaining
233 stability). Stage3 is also required if you want to install Gentoo using
234 prebuilt packages or without a network connection.
235 </p>
236
237 <table>
238 <tr>
239 <th>Stage3</th>
240 <th>Pros and Cons</th>

243 <th>+</th>
244 <ti>Fastest way to get a Gentoo base system</ti>

246 <tr>
247 <th>-</th>
248 <ti>You cannot tweak the base system - it's built already</ti>
249 </tr>
250 </table>
251
252 <p>
253 You might be interested to know that, if you decide to use different
254 optimization settings after having installed Gentoo, you will be able to
255 recompile your entire system with the new optimization settings.

262 <title>The Gentoo Installation CDs</title>
263 <subsection>
264 <title>Introduction</title>
265 <body>
266
267 <p>
268 The <e>Gentoo Installation CDs</e> are bootable CDs which contain a
269 self-sustained Gentoo environment. They allow you to boot Linux from the CD.
270 During the boot process your hardware is detected and the appropriate drivers
271 are loaded. They are maintained by Gentoo developers.
272 </p>
273
274 <p>
275 All Installation CDs allow you to boot, set up networking, initialize your
276 partitions and start installing Gentoo from the Internet. We currently provide
277 two Installation CDs which are equaly suitable to install Gentoo from, as long
278 as you're planning on performing an Internet-based installation using the
279 latest version of the available packages.
280 </p>
281
282 <p>
283 If you wish to install Gentoo without a working Internet connection, please use
284 the installation instructions described in the <uri
285 link="2005.0/index.xml">Gentoo 2005.0 Handbooks</uri>.
286 </p>
287
288 <p>
289 The two Installation CDs that we currently provide are:
290 </p>
291
292 <ul>
293 <li>
294 The Gentoo <e>Minimal</e> Installation CD, a small, no-nonsense, bootable
295 CD which sole purpose is to boot the system, prepare the networking and
296 continue with the Gentoo installation.
297 </li>
298 <li>
299 The Gentoo <e>Universal</e> Installation CD, a bootable CD with the same
300 abilities as the Minimal Installation CD. Additionally, it contains a
301 stage1 and several stage3 tarballs (optimized for the individual
302 subarchitectures).
303 </li>
304 </ul>
305
306 <p>
307 To help you decide which Installation CD you need, we have written down the
308 major advantages and disadvantages of each Installation CD.

318 The Minimal Installation CD is called <c>install-ppc-minimal-2005.0.iso</c> and
319 takes up only 52 MB of diskspace. You can use this Installation CD to install
320 Gentoo, but always with a working Internet connection only.

356 and consumes the entire surface of a 650 MB CD. You can use this Installation
357 CD to install Gentoo, and you can even use it to install Gentoo without a
358 working internet connection, just in case you want to bring Gentoo to another
359 PC than the one you are currently installing Gentoo on :)

387 You might find a so-called <e>Package CD</e> on one of our mirrors. This CD is
388 no Installation CD but an additional resource that can be exploited during a
389 networkless installation. It contains prebuilt packages (the so-called GRP
390 set) that allows you to easily and quickly install additional applications
391 (such as OpenOffice.org, KDE, GNOME, ...) immediately after the networkless
392 Gentoo installation.

401 <subsection>
402 <title>Downloading and Burning the Installation CDs</title>
403 <body>
404
405 <p>
406 You have chosen to use a Gentoo Installation CD. We'll first start by
407 downloading and burning the chosen Installation CD. We previously discussed
408 the several available Installation CDs, but where can you find them?
409 </p>
410
411 <p>
412 You can download any of the Installation CDs (and, if you want to, a Packages
413 CD as well) from one of our <uri link="/main/en/mirrors.xml">mirrors</uri>. The
414 Installation CDs are located in the <path>releases/ppc/2005.0/installcd</path>
415 directory.
416 </p>
417
418 <p>
419 Inside that directory you'll find so-called ISO-files. Those are full CD images
420 which you can write on a CD-R.
421 </p>
422
423 <p>
424 In case you wonder if your downloaded file is corrupted or not, you can
425 check its MD5 checksum and compare it with the MD5 checksum we provide (such as
426 <path>install-ppc-minimal-2005.0.iso.md5</path>). You can check the MD5 checksum
427 with the <c>md5sum</c> tool under Linux/Unix or <uri
428 link="http://www.etree.org/md5com.html">md5sum</uri> for Windows. How
429 to verify MD5 checksums with Mac OS X is described in the <uri
430 link="/doc/en/gentoo-ppc-faq.xml#doc_chap1">Gentoo PPC FAQ</uri>.
431 </p>
432
433 <p>
434 Another way to check the validity of the downloaded file is to use GnuPG to
435 verify the cryptographic signature that we provide (the file ending with
436 <path>.asc</path>). Download the signature file and obtain the public key:
437 </p>
438
439 <pre caption="Obtaining the public key">
440 $ <i>gpg --keyserver pgp.mit.edu --recv-keys 17072058</i>
441 </pre>
442
443 <p>
444 Now verify the signature:
445 </p>
446
447 <pre caption="Verify the cryptographic signature">
448 $ <i>gpg --verify &lt;signature file&gt; &lt;downloaded iso&gt;</i>
449 </pre>
450
451 <p>
452 To burn the downloaded ISO(s), you have to select raw-burning. How you
453 do this is highly program-dependent. We will discuss <c>cdrecord</c> and
454 <c>K3B</c> here; more information can be found in our <uri
455 link="/doc/en/faq.xml#isoburning">Gentoo FAQ</uri>.
456 </p>
457
458 <ul>
459 <li>
460 With cdrecord, you simply type <c>cdrecord dev=/dev/hdc &lt;downloaded iso
461 file&gt;</c> (replace <path>/dev/hdc</path> with your CD-RW drive's
462 device path).
463 </li>
464 <li>
465 With K3B, select <c>Tools</c> &gt; <c>CD</c> &gt; <c>Burn Image</c>. Then
466 you can locate your ISO file within the 'Image to Burn' area. Finally click
467 <c>Start</c>.
468 </li>

474 <title>Default: Booting the Installation CD with Yaboot</title>
475 <body>
476
477 <p>
478 On NewWorld machines place the Installation CD in the CD-ROM and reboot the
479 system. When the system-start-bell sounds, simply hold down the 'C' until the
480 CD loads.
481 </p>
482
483 <p>
484 After the Installation CD loaded, you will be greeted by a friendly welcome
485 message and a <e>boot:</e> prompt at the bottom of the screen.
486 </p>
487
488 <p>
489 At this prompt you are able to select a kernel for the subarchitecture you use.
490 We provide <c>G3</c>, <c>G4</c> and <c>G5</c>. All kernels are built with
491 support for multiple CPUs, but they will boot on single processor machines as
492 well.
493 </p>
494
495 <p>
496 You are also able to tweak some kernel options at this prompt. The following
497 table lists some of the available boot options you can add:

508 This option takes one of the following vendor-specific tags:
509 <c>radeonfb</c>, <c>rivafb</c>, <c>atyfb</c>, <c>aty128</c> or
510 <c>ofonly</c>. You can follow this tag with the resolution and refreshrate
511 you want to use. For instance <c>video=radeonfb:1280x1024@75</c>. If you are
512 uncertain what to choose, <c>ofonly</c> will most certainly work.

545 <title>Alternative: Booting the Installation CD on a Pegasos</title>
546 <body>
547
548 <p>
549 On the Pegasos simply insert the CD and at the SmartFirmware boot-prompt type
550 <c>boot cd /boot/menu</c>. This will open a small bootmenu where you can choose
551 between several preconfigured video configs. If you need any special boot
552 options you can append them to the command-line. For instance <c>boot cd
553 /boot/pegasos video=radeonfb:1280x1024@75 mem=256M</c>. The complete list of
554 kernel appends (in case something goes wrong and you need it) is preconfigured
555 in the kernel with <c>console=ttyS0,115200 console=tty0 init=/linuxrc
556 looptype=squashfs loop=/livecd.squashfs udev nodevfs cdroot root=/dev/ram0</c>.

563 <title>Alternative: Booting the Installation CD with BootX</title>
564 <body>
565
566 <p>
567 If you have an OldWorld Mac the bootable portion of the livecd can't be used.
568 The most simple solution is to use MacOS to bootstrap into a Linux environment
569 with a tool called BootX. Boot floppies are being prepared for Macs without
570 MacOS, but they are not available at this time.
571 </p>
572 <p>
573 First, download <uri link="http://penguinppc.org/projects/bootx/">BootX</uri>
574 and unpack the archive. Copy the the <c>BootX Extension</c> from the unpacked
575 archive into <c>Extensions Folder</c> and the BootX App Control Panel into
576 <c>Control Panels</c>, both of which are located in your MacOS System Folder.
577 Next, create a folder called "Linux Kernels" in your System folder and copy the
578 <c>G3G4</c> kernel from the CD to this folder. Finally, copy <c>G3G4.igz</c>
579 from the Installation CD <path>boot</path> folder into the MacOS
580 <c>System Folder</c>.
581 </p>
582 <p>
583 To prepare BootX, start the BootX App Control Panel. First select the Options
584 dialog and check <c>Use Specified RAM Disk</c> and select <c>G3G4.igz</c> from
585 your System Folder. Continue back to the initial screen and ensure that the
586 ramdisk size is at least <c>32000</c>. Finally, set the kernel arguments as
587 shown below:
588 </p>
589
590 <pre caption="BootX kernel arguments">
591 cdroot root=/dev/ram0 init=linuxrc loop=livecd.squashfs looptype=squashfs console=tty0 nodevfs udev
592 </pre>
593 <note>
594 The kernel parameters in the yaboot section above are also applicable here.
595 </note>
596 <p>
597 Check once more to make sure the settings are correct and then save the
598 configuration. This saves typing just in case it doesn't boot or something is
599 missing. Press the Linux button at the top of the window to boot into the
600 LiveCD and continue with <uri link="#booted">And When You're Booted...</uri>

610 You will be greeted by a root ("#") prompt on the current console. You can also
611 switch to other consoles by pressing Alt-F2, Alt-F3 and Alt-F4. Get
612 back to the one you started on by pressing Alt-F1. Probably you have to hit
613 Alt-fn-Fx on Apple machines.

617 If you are installing Gentoo on a system with a non-US keyboard, use
618 <c>loadkeys</c> to load the keymap for your keyboard. To list the available
619 keymaps, execute <c>ls /usr/share/keymaps/i386</c>. On NewWorld machines or the
620 Pegasos do not use the keymaps in <path>ppc</path> or <path>mac</path> as they
621 are for ADB-based OldWorld machines.

650 When the Installation CD boots, it tries to detect all your hardware devices and
651 loads the appropriate kernel modules to support your hardware. In the
652 vast majority of cases, it does a very good job. However, in some cases, it may
653 not auto-load the kernel modules you need. If the PCI auto-detection missed some
654 of your system's hardware, you will have to load the appropriate kernel modules
655 manually.

659 In the next example we try to load the <c>airport</c> module. This module
660 supports only the old Airport cards (b-net). AirportExtreme is currently not
661 supported under Linux:

671 <title>Optional: Tweaking Hard Disk Performance</title>
672 <body>
673
674 <p>
675 If you are an advanced user, you might want to tweak the IDE hard disk
676 performance using <c>hdparm</c>. With the <c>-tT</c> options you can
677 test the performance of your disk (execute it several times to get a
678 more precise impression):
679 </p>
680
681 <pre caption="Testing disk performance">
682 # <i>hdparm -tT /dev/hda</i>
683 </pre>
684
685 <p>
686 To tweak, you can use any of the following examples (or experiment
687 yourself) which use <path>/dev/hda</path> as disk (substitute with your
688 disk):
689 </p>
690
691 <pre caption="Tweaking hard disk performance">

701
702 <p>
703 If you plan on giving other people access to your installation
704 environment or you want to chat using <c>irssi</c> without root privileges (for
705 security reasons), you need to create the necessary user accounts and change
706 the root password.
707 </p>
708
709 <p>
710 To change the root password, use the <c>passwd</c> utility:
711 </p>
712
713 <pre caption="Changing the root password">
714 # <i>passwd</i>
715 New password: <comment>(Enter your new password)</comment>
716 Re-enter password: <comment>(Re-enter your password)</comment>
717 </pre>
718
719 <p>
720 To create a user account, we first enter their credentials, followed by
721 its password. We use <c>useradd</c> and <c>passwd</c> for these tasks.
722 In the next example, we create a user called &quot;john&quot;.
723 </p>
724
725 <pre caption="Creating a user account">
726 # <i>useradd -m -G users john</i>
727 # <i>passwd john</i>
728 New password: <comment>(Enter john's password)</comment>
729 Re-enter password: <comment>(Re-enter john's password)</comment>
730 </pre>
731
732 <p>
733 You can change your user id from root to the newly created user by using
734 <c>su</c>:

745 <body>
746
747 <p>
748 If you want to view the Gentoo Handbook (either from-CD or online) during the
749 installation, make sure you have created a user account (see <uri
750 link="#useraccounts">Optional: User Accounts</uri>). Then press <c>Alt-F2</c> to
751 go to a new terminal and log in.
752 </p>
753
754 <p>
755 If you want to view the documentation on the CD you can immediately run
756 <c>links2</c> to read it:
757 </p>
758
759 <pre caption="Viewing the on-CD documentation">
760 # <i>links2 /mnt/cdrom/docs/html/index.html</i>
761 </pre>
762
763 <p>
764 However, it is preferred that you use the online Gentoo Handbook as it will be
765 more recent than the one provided on the CD. You can view it using <c>links2</c>
766 as well, but only after having completed the <e>Configuring your Network</e>
767 chapter (otherwise you won't be able to go on the Internet to view the
768 document):
769 </p>
770
771 <pre caption="Viewing the Online Documentation">
772 # <i>links2 http://www.gentoo.org/doc/en/handbook/handbook-ppc.xml</i>
773 </pre>

782 <title>Optional: Starting the SSH Daemon</title>
783 <body>
784
785 <p>
786 If you want to allow other users to access your computer during the
787 Gentoo installation (perhaps because those users are going to help you
788 install Gentoo, or even do it for you), you need to create a user
789 account for them and perhaps even provide them with your root password
790 (<e>only</e> do that <e>if</e> you <b>fully trust</b> that user).
791 </p>
792
793 <p>
794 To fire up the SSH daemon, execute the following command:
795 </p>
796
797 <pre caption="Starting the SSH daemon">
798 # <i>/etc/init.d/sshd start</i>
799 </pre>
800
801 <p>
802 To be able to use sshd, you first need to set up your networking. Continue with
803 the chapter on <uri link="?part=1&amp;chap=3">Configuring your Network</uri>.
