17     Before we start, we first list what hardware requirements you need to
18     successfully install Gentoo on your box. This of course depends on your
19     architecture.

27    
28     <p>
29     Check the following requirements before you
30     continue with the Gentoo installation:
31     </p>
32    
33     <ul>
34     <li>
35     You need at least 1 Gb of free disk space
36     </li>
37     <li>
38     If you do not use prebuilt packages, you need at least 300 Mb of memory (RAM +
39     swap)
40     </li>
41     <li>
42     For the <e>SPARC architecture</e>, you should check with the <uri
43     link="http://www.ultralinux.org/faq.html#s_2">UltraLinux FAQ</uri>

55    
56     <p>
57     Still interested in trying out Gentoo? Well, then it is now time to
58     choose the installation medium you want to use. Yes, you have the
59     choice, no, they are not all equal, and yes, the result is always the same: a
60     Gentoo base system.
61     </p>
62    
63     <p>
64     The installation media we will describe are:
65     </p>
66    
67     <ul>
68     <li>Gentoo's Minimal LiveCD</li>
69     <li>Gentoo's Universal LiveCD</li>
70     </ul>
71    
72     <p>
73     Every single media has its advantages and disadvantages. We will list
74     the pros and cons of every medium so you have all the information to
75     make a justified decision. But before we continue, let's explain our
76     three-stage installation.

82     <title>The Three Stages</title>
83     <body>
84    
85     <p>
86     Gentoo Linux can be installed using one of three <e>stage</e> tarball files.
87     The one you choose depends on how much of the system you want to compile
88     yourself. The <e>stage1</e> tarball is used when you want to bootstrap and
89     build the entire system from scratch. The <e>stage2</e> tarball is used for
90     building the entire system from a bootstrapped &quot;semi-compiled&quot; state.
91     The <e>stage3</e> tarball already contains a basic Gentoo Linux system that has
92     been built for you. As we will explain later, you can also install
93     Gentoo without compiling anything (except your kernel and some optional
94     packages). If you want this, you have to use a <e>stage3</e> tarball.
95     </p>
96    
97     <p>
98     Now what stage do you have to choose?
99     </p>
100    
101     <p>
102     Starting from a <e>stage1</e> allows you to have total control over the
103     optimization settings and optional build-time functionality that is
104     initially enabled on your system. This makes <e>stage1</e> installs good for
105     power users who know what they are doing. It is also a great
106     installation method for those who would like to know more about the
107     inner workings of Gentoo Linux.
108     </p>
109    
110 swift 1.8 <p>
111     A <e>stage1</e> installation can only be performed when you have a working
112     Internet connection.

153     <p>
154     <e>Stage2</e> installs allow you to skip the bootstrap process and doing this
155     is fine if you are happy with the optimization settings that we chose
156     for your particular <e>stage2</e> tarball.
157     </p>

201     <p>
202     Choosing to go with a <e>stage3</e> allows for the fastest install of Gentoo
203     Linux, but also means that your base system will have the optimization
204     settings that we chose for you (which to be honest, are good settings
205     and were carefully chosen to enhance performance while maintaining
206     stability). <e>stage3</e> is also required if you want to install Gentoo using
207 swift 1.7 prebuilt packages or without a network connection.

234     Write down (or remember) what stage you want to use. You need this later when
235     you decide what LiveCD (or other installation medium) you want to use. You might
236     be interested to know that, if you decide to use different optimization settings
237     after having installed Gentoo, you will be able to recompile your entire system
238     with the new optimization settings.
239     </p>
240    
241     <p>
242     Now take a look at the available installation media.

248     <title>Gentoo LiveCDs</title>
249     <body>
250    
251     <p>
252     The <e>Gentoo LiveCDs</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 LiveCDs allow you to boot, setup networking, initialize your
260     partitions and start installing Gentoo from the Internet. However, some
261     LiveCDs also contain all necessary source code so you are able to install
262     Gentoo without a working network configuration.
263     </p>
264    
265     <p>
266     Now what do these LiveCDs contain?

272     <title>Gentoo's Minimal LiveCD</title>
273     <body>
274    
275     <p>
276     This is a small, no-nonsense, bootable CD which sole purpose is to boot the
277     system, prepare the networking and continue with the Gentoo installation. It
278     does not contain any stages (or, in some cases, a single stage1 file),
279     source code or precompiled packages. For example the sparc64 variant of this
280     LiveCD can be found in the <path>sparc64/</path> subdirectory and is called
281 swift 1.6 <c>install-sparc64-minimal-2004.1.iso</c>.

316     <title>Gentoo's Universal LiveCD</title>
317     <body>
318    
319     <p>
320     Gentoo's Universal LiveCD is a bootable CD suitable to install Gentoo without
321     networking. It contains a stage1 and stage3 tarballs (optimized for the
322     sparc architecture). For example the sparc64 variant of this CD is called
323 swift 1.6 <c>install-sparc64-universal-2004.1.iso</c> and can be found in the
324 swift 1.1 <path>sparc64/</path> subdirectory.
325     </p>
326    
327     <p>
328     If you take a closer look into the directories you will see
329     that we provide a <e>Gentoo Package CD</e>. This CD (which isn't
330     bootable) only contains precompiled packages and can be used to install software
331     after a succesfull Gentoo Installation. To install Gentoo, you only
332     need the Universal LiveCD, but if you want OpenOffice.org, Mozilla, KDE, GNOME
333     etc. without having to compile every single one of them, you need the Packages
334     CD too. Such a Packages CD for sparc64 is called
335 swift 1.6 <c>packages-sparc64-2004.1.iso</c>.
336 swift 1.1 </p>
337    
338 swift 1.9 <p>
339     You only need the Packages CD if you want to perform a stage3 with GRP
340     installation.

376     <subsection>
377     <title>Downloading and Burning the LiveCDs</title>
378     <body>
379    
380     <p>
381     You have chosen to use a Gentoo LiveCD (if not, then you are reading the
382     wrong section). We'll first start by downloading and burning the chosen
383     LiveCD. We previously discussed the several available LiveCDs, but where can you
384     find them?
385     </p>
386    
387     <p>
388     Visit one of our <uri
389     link="/main/en/mirrors.xml">mirrors</uri> and go to
390 swift 1.6 <path>releases/sparc/2004.1/livecd</path> where the LiveCD(s) of
391     your choice are located. Inside the subdirectories <path>sparc32/</path> and
392     <path>sparc64/</path> you'll find so-called ISO-files.
393 swift 1.1 Those are full CD images which you can write on a CD-R.
394     </p>
395    
396     <p>
397     In case you wonder if your downloaded file is corrupted or not, you can
398     check its MD5 checksum and compare it with the MD5 checksum we provide (such as
399 swift 1.6 <path>install-sparc64-minimal-2004.1.iso.md5</path>). You can check the MD5
400 swift 1.1 checksum with the <c>md5sum</c> tool under Linux/Unix or <uri
401     link="http://www.md5summer.org">md5summer</uri> for Windows.
402     </p>
403    
404     <p>
405     To burn the downloaded ISO(s), you have to select raw-burning. How you
406     do this is highly program-dependent. We will discuss a couple of popular
407     tools on how to do this.
408     </p>
409    
410     <ul>
411     <li>
412     With EasyCD Creator you select <c>File</c>, <c>Record CD
413     from CD image</c>. Then you change the <c>Files of type</c> to <c>ISO image
414     file</c>. Then locate the ISO file and click <c>Open</c>. When you click on
415     <c>Start recording</c> the ISO image will be burned correctly onto the CD-R.
416     </li>
417     <li>
418     With Nero Burning ROM, select <c>File</c>, <c>Burn CD image</c>. Set the
419     type of file to <c>*.*</c> and select the ISO file. Older versions of Nero
420     will tell you they don't recognize the format -- confirm here, it does
421     recognize it but doesn't know it yet :) In the next dialog, set the
422     following parameters:
423     <ul>
424     <li>Type of image: <c>Data Mode 1</c></li>
425     <li>Block size: <c>2048 bytes</c></li>
426     <li>File precursor and length of the image trailer: <c>0 bytes</c></li>
427     <li>Scrambled: <c>no</c></li>
428     <li>Swapped: <c>no</c></li>
429     </ul>
430     Now click on <c>OK</c> and then <c>Burn</c> (the CD-R)
431     </li>
432     <li>
433     With cdrecord, you simply type <c>cdrecord dev=/dev/hdc</c> (replace
434     <path>/dev/hdc</path> with your CD-RW drive's device path) followed
435     by the path to the ISO file :)
436     </li>
437 swift 1.2 <li>
438 bennyc 1.5 With K3B, select <c>Tools</c> &gt; <c>CD</c> &gt; <c>Burn Image</c>. Then
439     you can locate your ISO file within the 'Image to Burn' area. Finally click
440 swift 1.2 <c>Start</c>.
441     </li>
442 swift 1.1 </ul>

447     <title>Booting the SPARC LiveCD</title>
448     <body>
449    
450     <p>
451     Insert the Gentoo LiveCD in the CD-ROM and boot your system. During startup,
452     press Stop-A to enter OpenBootPROM (OBP). Once you are in the OBP, boot from the
453     CD-ROM:
454     </p>
455    
456     <pre caption="Booting the LiveCD">
457     ok <i>boot cdrom</i>
458     </pre>
459    
460     <p>
461     You will be greeted by the SILO boot manager (on the LiveCD). Type in
462 swift 1.6 <c>gentoo-2.4</c> (single-CPU kernel) or <c>gentoo-2.4-smp</c>
463     (multi-CPU kernel) and press enter to continue booting the system. In the
464     following example we'll boot the <c>gentoo-2.4</c> kernel.

467     <pre caption="Continue booting from the LiveCD">
468 swift 1.6 boot: <i>gentoo-2.4</i>

470    
471     <p>
472     Once the LiveCD is booted, you will be greeted by a login prompt. Log on as
473     <c>root</c>. There is no password, so when you are asked for one, press Enter.

546     If you plan on giving other people access to your installation
547     environment or you want to chat using <c>irssi</c> without root privileges (for
548     security reasons), you need to create the necessary user accounts and change
549     the root password.
550     </p>
551    
552     <p>
553     To change the root password, use the <c>passwd</c> utility:
554     </p>
555    
556     <pre caption="Changing the root password">
557     # <i>passwd</i>
558     New password: <comment>(Enter your new password)</comment>
559     Re-enter password: <comment>(Re-enter your password)</comment>
560     </pre>
561    
562     <p>
563 swift 1.4 To create a user account, we first enter their credentials, followed by
564 swift 1.1 its password. We use <c>useradd</c> and <c>passwd</c> for these tasks.
565     In the next example, we create a user called &quot;john&quot;.
566     </p>
567    
568     <pre caption="Creating a user account">
569     # <i>useradd john</i>
570     # <i>passwd john</i>
571     New password: <comment>(Enter john's password)</comment>
572     Re-enter password: <comment>(Re-enter john's password)</comment>
573     </pre>
574    
575     <p>
576     You can change your user id from root to the newly created user by using
577     <c>su</c>:
578     </p>

589    
590     <p>
591     If you want to allow other users to access your computer during the
592     Gentoo installation (perhaps because those users are going to help you
593     install Gentoo, or even do it for you), you need to create a user
594     account for them and perhaps even provide them with your root password
595     (<e>only</e> do that <e>if</e> you <b>fully trust</b> that user).
596     </p>
597    
598     <p>
599     To fire up the SSH daemon, execute the following command:
600     </p>
601    
602     <pre caption="Starting the SSH daemon">
603     # <i>/etc/init.d/sshd start</i>
604     </pre>
605    
606     <p>
607     To be able to use sshd, you first need to setup your networking. Continue with
608     the chapter on <uri link="?part=1&amp;chap=3">Configuring your Network</uri>.
