66 <title>The Gentoo Installation Approaches</title>
67 <subsection>
68 <title>Introduction</title>
69 <body>

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

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

158 <p>
159 A <e>stage2</e> is used for building the entire system from a bootstrapped
160 "semi-compiled" state.
161 </p>
162
163 <p>
164 Stage2 installs allow you to skip the bootstrap process; doing this
165 is fine if you are happy with the optimization settings that we chose
166 for your particular stage2 tarball.

203 <title>A Stage3 Approach</title>
204 <body>
205
206 <p>
207 A <e>stage3</e> installation contains a basic Gentoo Linux system that has been
208 built for you. You will only need to build a few packages of which we can't
209 decide for you which one to choose.
210 </p>
211
212 <p>
213 Choosing to go with a stage3 allows for the fastest install of Gentoo
214 Linux, but also means that your base system will have the optimization
215 settings that we chose for you (which to be honest, are good settings
216 and were carefully chosen to enhance performance while maintaining
217 stability). Stage3 is also required if you want to install Gentoo using
218 prebuilt packages or without a network connection.

232 <ti>You cannot tweak the base system - it's built already</ti>
233 </tr>
234 </table>
235
236 <p>
237 You might be interested to know that, if you decide to use different
238 optimization settings after having installed Gentoo, you will be able to
239 recompile your entire system with the new optimization settings.

246 <title>The Gentoo Installation CDs</title>
247 <subsection>
248 <title>Introduction</title>
249 <body>
250
251 <p>
252 The <e>Gentoo Installation CDs</e> are bootable CDs which contain a
253 self-sustained Gentoo environment. They allow you to boot Linux from the CD.
254 During the boot process your hardware is detected and the appropriate drivers
255 are loaded. They are maintained by Gentoo developers.
256 </p>
257
258 <p>
259 All Installation CDs allow you to boot, set up networking, initialize your
260 partitions and start installing Gentoo from the Internet. We currently provide
261 two Installation CDs which are equaly suitable to install Gentoo from, as long
262 as you're planning on performing an Internet-based installation using the latest
263 version of the available packages.
264 </p>
265
266 <p>
267 If you wish to install Gentoo without a working Internet connection, please use
268 the installation instructions described in the <uri
269 link="2005.0/index.xml">Gentoo 2005.0 Handbooks</uri>.
270 </p>
271
272 <p>
273 The two Installation CDs that we currently provide are:
274 </p>
275
276 <ul>
277 <li>
278 The Gentoo <e>Minimal</e> Installation CD, a small, no-nonsense, bootable CD
279 which sole purpose is to boot the system, prepare the networking and
280 continue with the Gentoo installation.
281 </li>
282 <li>
283 The Gentoo <e>Universal</e> Installation CD, a bootable CD with the same
284 abilities as the Minimal Installation CD. Additionally, it contains a
285 stage1 and several stage3 tarballs (optimized for the individual
286 subarchitectures).
287 </li>
288 </ul>
289
290 <p>
291 We currently only provide Installation CDs for the sparc64 architecture. Users
292 of sparc32 can use the experimental netboot images to install Gentoo from.
293 More information about netbooting can be found in our <uri
294 link="/doc/en/gentoo-sparc-netboot-howto.xml">Gentoo/SPARC Netboot
295 HOWTO</uri>.
296 </p>

299 To help you decide which Installation CD you need, we have written down the
300 major advantages and disadvantages of each Installation CD.

349 650 MB CD. You can use this Installation CD to install
350 Gentoo, and you can even use it to install Gentoo without a working internet
351 connection, just in case you want to bring Gentoo to another PC than the one you
352 are currently installing Gentoo on :)

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

393 <title>Download, Burn and Boot a Gentoo Installation CD</title>
394 <subsection>
395 <title>Downloading and Burning the Installation CDs</title>
396 <body>
397
398 <p>
399 You have chosen to use a Gentoo Installation CD. We'll first start by
400 downloading and burning the chosen Installation CD. We previously discussed
401 the several available Installation CDs, but where can you find them?
402 </p>
403
404 <p>
405 You can download any of the Installation CDs (and, if you want to, a Packages
406 CD as well) from one of our <uri link="/main/en/mirrors.xml">mirrors</uri>. The
407 Installation CDs are located in the
408 <path>releases/sparc/2005.0/installcd/sparc64</path> directory.
409 </p>
410
411 <p>
412 Inside that directory you'll find so-called ISO-files. Those are full CD images
413 which you can write on a CD-R.
414 </p>
415
416 <p>
417 In case you wonder if your downloaded file is corrupted or not, you can check its
418 MD5 checksum and compare it with the MD5 checksum we provide (such as
419 <path>install-sparc64-minimal-2005.0.iso.md5</path>). You can check the MD5
420 checksum with the <c>md5sum</c> tool under Linux/Unix or <uri
421 link="http://www.etree.org/md5com.html">md5sum</uri> for Windows.
422 </p>
423
424 <p>
425 Another way to check the validity of the downloaded file is to use GnuPG to
426 verify the cryptographic signature that we provide (the file ending with
427 <path>.asc</path>). Download the signature file and obtain the public key:
428 </p>
429
430 <pre caption="Obtaining the public key">
431 $ <i>gpg --keyserver pgp.mit.edu --recv-keys 17072058</i>
432 </pre>
433
434 <p>
435 Now verify the signature:
436 </p>
437
438 <pre caption="Verify the cryptographic signature">
439 $ <i>gpg --verify &lt;signature file&gt; &lt;downloaded iso&gt;</i>
440 </pre>
441
442 <p>
443 To burn the downloaded ISO(s), you have to select raw-burning. How you
444 do this is highly program-dependent. We will discuss <c>cdrecord</c> and
445 <c>K3B</c> here; more information can be found in our <uri
446 link="/doc/en/faq.xml#isoburning">Gentoo FAQ</uri>.
447 </p>
448
449 <ul>
450 <li>
451 With cdrecord, you simply type <c>cdrecord dev=/dev/hdc &lt;downloaded iso
452 file&gt;</c> (replace <path>/dev/hdc</path> with your CD-RW drive's device
453 path).
454 </li>
455 <li>
456 With K3B, select <c>Tools</c> &gt; <c>CD</c> &gt; <c>Burn Image</c>. Then
457 you can locate your ISO file within the 'Image to Burn' area. Finally click
458 <c>Start</c>.
459 </li>
460 </ul>

465 <title>Booting the Installation CD</title>
466 <body>
467
468 <p>
469 Insert the Gentoo Installation CD in the CD-ROM and boot your system. During
470 startup, press Stop-A to enter OpenBootPROM (OBP). Once you are in the OBP,
471 boot from the CD-ROM:
472 </p>
473
474 <pre caption="Booting the Installation CD">
475 ok <i>boot cdrom</i>
476 </pre>
477
478 <p>
479 You will be greeted by the SILO boot manager (on the Installation CD). Type in
480 <c>gentoo-2.4</c> (single-CPU kernel) or <c>gentoo-2.4-smp</c>
481 (multi-CPU kernel) and press enter to continue booting the system. In the
482 following example we'll boot the <c>gentoo-2.4</c> kernel.
483 </p>
484
485 <pre caption="Continue booting from the Installation CD">
486 boot: <i>gentoo-2.4</i>
487 </pre>
488
489 <p>
490 Once the Installation CD is booted, you will be automatically logged on to the
491 system.
492 </p>
493
494 <p>
495 You should have a root ("#") prompt on the current console and can also switch
496 to other consoles by pressing Alt-F2, Alt-F3 and Alt-F4. Get back to the one you
497 started on by pressing Alt-F1. You will also find a root prompt on the serial
498 console (<path>ttyS0</path>).
499 </p>
500
501 <p>
502 Continue with <uri link="#hardware">Extra Hardware Configuration</uri>.

511 <p>
512 If not all hardware is supported out-of-the-box, you will need to load the
513 appropriate kernel modules.
514 </p>
515
516 <p>
517 In the next example we try to load the <c>8139too</c> module (support for
518 certain kinds of network interfaces):
519 </p>

527 <subsection id="useraccounts">
528 <title>Optional: User Accounts</title>
529 <body>
530
531 <p>
532 If you plan on giving other people access to your installation
533 environment or you want to chat using <c>irssi</c> without root privileges (for
534 security reasons), you need to create the necessary user accounts and change
535 the root password.
536 </p>
537
538 <p>
539 To change the root password, use the <c>passwd</c> utility:
540 </p>
541
542 <pre caption="Changing the root password">
543 # <i>passwd</i>
544 New password: <comment>(Enter your new password)</comment>
545 Re-enter password: <comment>(Re-enter your password)</comment>
546 </pre>
547
548 <p>
549 To create a user account, we first enter their credentials, followed by
550 its password. We use <c>useradd</c> and <c>passwd</c> for these tasks.
551 In the next example, we create a user called &quot;john&quot;.
552 </p>
553
554 <pre caption="Creating a user account">
555 # <i>useradd -m -G users john</i>
556 # <i>passwd john</i>
557 New password: <comment>(Enter john's password)</comment>
558 Re-enter password: <comment>(Re-enter john's password)</comment>
559 </pre>
560
561 <p>
562 You can change your user id from root to the newly created user by using
563 <c>su</c>:
564 </p>
565
566 <pre caption="Changing user id">
567 # <i>su - john</i>

572 <subsection>
573 <title>Optional: Viewing Documentation while Installing</title>
574 <body>
575
576 <p>
577 If you want to view the Gentoo Handbook (either from-CD or online) during the
578 installation, make sure you have created a user account (see <uri
579 link="#useraccounts">Optional: User Accounts</uri>). Then press <c>Alt-F2</c> to
580 go to a new terminal and log in.
581 </p>
582
583 <p>
584 If you want to view the documentation on the CD you can immediately run
585 <c>links2</c> to read it:

587
588 <pre caption="Viewing the on-CD documentation">
589 # <i>links2 /mnt/cdrom/docs/html/index.html</i>
590 </pre>
591
592 <p>
593 However, it is preferred that you use the online Gentoo Handbook as it will be
594 more recent than the one provided on the CD. You can view it using <c>links2</c>
595 as well, but only after having completed the <e>Configuring your Network</e>
596 chapter (otherwise you won't be able to go on the Internet to view the
597 document):

613
614 <p>
615 If you want to allow other users to access your computer during the
616 Gentoo installation (perhaps because those users are going to help you
617 install Gentoo, or even do it for you), you need to create a user
618 account for them and perhaps even provide them with your root password
619 (<e>only</e> do that <e>if</e> you <b>fully trust</b> that user).
620 </p>
621
