1 $NetBSD: install,v 1.3 1998/01/09 18:48:04 perry Exp $ 2 3Installing NetBSD is a relatively complex process, but if you have 4this document in hand and are careful to read and remember the 5information which is presented to you by the install program, it 6shouldn't be too much trouble. 7 8Before you begin, you should know the geometry of your hard disk, i.e. 9the sector size (note that sector sizes other than 512 bytes are not 10currently supported), the number of sectors per track, the number of 11tracks per cylinder (also known as the number of heads), and the 12number of cylinders on the disk. The NetBSD kernel will try to 13discover these parameters on its own, and if it can it will print them 14at boot time. If possible, you should use the parameters it prints. 15(You might not be able to because you're sharing your disk with 16another operating system, or because your disk is old enough that the 17kernel can't figure out its geometry.) 18 19If NetBSD will be sharing the disk with Human68k or another operating 20system, you should have already completed the section of these notes 21that instructed you on how to prepare your hard disk. You should know 22the size of the NetBSD area of the disk and its offset from the 23beginning of the disk. You will need this information when setting up 24your NetBSD partitions. 25 26You should now be ready to install NetBSD. It might be handy for you 27to have a pencil, some paper, and a calculator handy. 28 29The following is a walk-through of the steps you will take while 30getting NetBSD installed on your hard disk. If any question has a 31default answer, it will be displayed in brackets ("[]") after the 32question. If you wish to stop the installation, you may hit Control-C 33at any time, but if you do, you'll have to begin the installation 34process again from scratch. 35 36 Boot your machine using of the appropriate kernel-copy floppy. 37 If the boot prompt does not appear in a reasonable amount of 38 time, you either have a bad boot floppy or a hardware problem. 39 Try writing the kernel-copy floppy image to a different disk, 40 and using that. If it still doesn't work, NetBSD probably 41 can't be run on your hardware. This can probably be 42 considered a bug, so you might want to report it. If you do, 43 please include as many details about your system configuration 44 as you can. 45 46 It will take a while to load the kernel from the floppy, 47 probably around a minute or so. After its loaded, you will be 48 presented with the message: 49 "Insert file system floppy" 50 If you do not see that message after a reasonable time has 51 elapsed, or the spinning cursor has stopped and nothing 52 further has happened, either your boot floppy is bad or you 53 are having hardware problems, and should proceed as outlined 54 above. 55 56 Once you have reached that prompt, remove the kernel-copy 57 floppy from the floppy drive. Make sure that the installation 58 disk (the "inst12" floppy) is writable, insert it into the 59 floppy drive, and hit any key. 60 61 You will then be presented with the NetBSD kernel boot 62 messages. You will want to read them, to determine your 63 disk's name and geometry. Its name will be something like 64 "sd0" or "wd0" and the geometry will be printed on a line that 65 begins with its name. As mentioned above, you will need your 66 disk's geometry when creating NetBSD's partitions. You will 67 also need to know the name, to tell the install tools what 68 disk to install on. 69 70 While booting, you will probably see several warnings. You 71 should be warned that no swap space is present, and that 72 init(8) cannot find /etc/rc. Do not be alarmed, these are 73 completely normal. When you reach the prompt asking you for a 74 shell name, just hit return. 75 76 You will be presented with a welcome message and a prompt, 77 asking if you wish to proceed with the installation process. 78 If you wish to proceed, enter "y" and hit return. 79 80 You will be asked what type of disk driver you have. The 81 valid options are listed by the install program, to make sure 82 you get it right. If you are SURE that it does, reply 83 affirmatively. Otherwise, the install program will 84 automatically reserve space for bad144 tables. 85 86 The install program will then tell you which disks of that 87 type it can install on, and ask you which it should use. 88 Reply with the name of your disk. 89 90 You will then be asked to name your disk's disklabel. The 91 default response is "mywd" or "mysd" depending on the type of 92 your disk, and for most purposes it will be OK. If you choose 93 to name it something different, make sure the name is a single 94 word and contains no special characters. You don't need to 95 remember this name. 96 97 You will be prompted for your disk's geometry information, 98 i.e. the number of bytes per sector, cylinders on the disk, 99 tracks per cylinder (heads), and sectors per track. Enter 100 them when they are requested. If you make a mistake, hit 101 Control-C and when you get to the shell prompt, restart the 102 install process by running the "install" command. Once you 103 have entered this data, the install program will tell you the 104 total size of your disk, in both sectors, and cylinders. 105 Remember this number; if you're installing on the whole disk, 106 you'll need it again soon. 107 108 When describing your partitions, you will have the option of 109 entering data about them in units of disk sectors or 110 cylinders. If you choose to enter the information in units of 111 sectors, remember that, for optimal performance, partitions 112 should begin and end on cylinder boundaries. You will be 113 asked about which units you wish to use, and you should reply 114 with "c" for cylinders, or "s" for sectors. 115 116 You will be asked for the size of the NetBSD portion of the 117 disk. If you're installing on the whole disk, reply with the 118 size of the disk, as printed earlier by the install program. 119 If you're using only part of the disk, reply with the size 120 that you specified in the partition editor. (Don't forget to 121 enter the size in the units you specified in the last step!) 122 123 If you are not installing on the whole disk, you will be asked 124 fro the offset of the NetBSD partition from the beginning of 125 the disk. Reply with the appropriate offset (again, in 126 whichever units you specified), as determined by how you 127 set up your disk using the partition editor. 128 129 You will be asked to enter the size of your NetBSD root 130 partition. It should be at least 13M, but if you are going to 131 be doing development, 14-16M is a more desirable size. This 132 size should be expressed in units of sectors or cylinders, 133 depending on which you said you wanted to use. 134 135 Next, you will be asked for the size of your swap partition. 136 You should probably allocate twice as much swap space as you 137 have real memory. Systems that will be heavily used should 138 have more swap space allocated, and systems that will be 139 lightly used can get by with less. If you want the system to 140 be able to save crash dumps when it panics, you will need at 141 least as much swap space as you have RAM. Again, this number 142 should be expressed in units of sectors or cylinders, as 143 appropriate. 144 145 The install program will then ask you for information about 146 the rest of the partitions you want on your disk. For most 147 purposes, you will want only one more partition, "/usr". 148 (Machines used as servers will probably also want /var as a 149 separate partition. That can be done with these installation 150 tools, but is not covered here.) The install program will 151 tell you how much space there is left to be allocated in the 152 NetBSD area of the disk, and, if you only want one more 153 partition ("/usr"), you should enter it at the prompt when the 154 installer asks you how large the next partition should be. 155 It will then ask you for the name of the mount point for that 156 partition. If you're doing a basic installation, that is 157 "/usr". 158 159 YOU ARE NOW AT THE POINT OF NO RETURN. Nothing has been 160 written to your disk yet, but if you confirm that you want to 161 install NetBSD, your hard drive will be modified, and its 162 contents may be scrambled at the whim of the install program. 163 This is especially likely if you have given the install 164 program incorrect information. If you are sure you want to 165 proceed, enter "yes" at the prompt. 166 167 The install program will now label your disk and make the file 168 systems you specified. The filesystems will be initialized to 169 contain NetBSD bootstrapping binaries and configuration files. 170 It will also create an /etc/fstab for your system, and mount 171 all of the file systems under /mnt. (In other words, your root 172 partition will be mounted on /mnt, your /usr partition on 173 /mnt/usr, and so on.) There should be no errors in this 174 section of the installation. If there are, restart from the 175 beginning of the installation process. 176 177 You will be placed at a shell prompt ("#"). The remaining 178 tasks are to copy the kernel from the kernel copy floppy to 179 the hard drive's root filesystem and install the distribution 180 sets. The flow of installation differs depending on your 181 hardware resources, and on what media the distribution sets 182 reside. 183 184 To install from floppy: 185 If you only have only one floppy drive, the order of 186 installation is different. Follow the directions in 187 the "Kernel installation" section which will help you 188 install a kernel on the hard drive and then boot off 189 the hard drive, then continue with the rest of the 190 process described here to install the distribution 191 sets from floppy: 192 193 The first thing you should do is pick a temporary 194 directory where the distribution files can be stored. 195 To do this, enter the command "Set_tmp_dir", and enter 196 the name of the temporary directory. (Don't forget 197 that if your disk is still mounted under /mnt; you 198 should probably pick a directory under /mnt/usr.) 199 200 After you have picked a temporary directory, enter the 201 "Load_fd" command, to load the distribution sets from 202 your floppies. 203 204 You will be asked which floppy drive to use. Enter 205 "0" (zero) if you're using the first floppy drive 206 (i.e. what DOS would call "A:"), or enter "1" if 207 you're using the second. (Remember that you CANNOT 208 use the floppy drive that you booted from. If you 209 booted from "A:", you must load from "B:".) 210 211 You will be prompted to insert a floppy into the drive, 212 to have its contents copied to your hard disk. Do so, 213 and hit return to begin copying. When that is done, 214 read the remainder of the floppies that contain the 215 distribution sets that you want to install, one by 216 one. When the last is read, and you are being 217 prompted for another, hit Control-C. 218 219 Run the "Extract" command once for each distribution 220 set you wish to install. For instance, if you wish to 221 install the "base12" distribution set, followed by the 222 "man12" distribution set, and finally the "etc12" 223 distribution set, use the commands: 224 Extract base12 225 Extract man12 226 Extract etc12 227 228 For each extraction, it will ask you if the extraction 229 should be verbose. If you reply affirmatively, it 230 will print out the name of each file that's being 231 extracted. 232 233 (Note: if you know that you will be running low on 234 disk space when installing NetBSD, you can load and 235 extract one distribution set at a time. To do this, 236 load only the floppies which contain the files for the 237 first distribution set, extract them, and then change 238 to the temporary directory and remove them with the 239 command "rm set_name.??".) 240 241 Once you are finished extracting all of the sets that 242 you wish to install, you should proceed to the 243 instructions below (after the last install medium 244 type-specific instructions), that explain how you 245 should configure your system. 246 247 To install from tape: 248 The first thing you should do is pick a temporary 249 directory where the distribution files can be stored. 250 To do this, enter the command "Set_tmp_dir", and enter 251 the name of the temporary directory. (Don't forget 252 that your disk is mounted under /mnt; you should 253 probably pick a directory under /mnt/usr.) The 254 default is /mnt/usr/distrib. 255 256 After you have picked a temporary directory, enter the 257 "Load_tape" command, to load the distribution sets from 258 tape. 259 260 You will be asked which tape drive to use. The 261 default is "rst0", which is correct if you're using 262 the SCSI tape drive with the lowest SCSI ID number. 263 (For the SCSI tape drive with the next lowest SCSI ID 264 number, you should use "rst1", and so on.) 265 266 You will be prompted to hit return when you have 267 inserted the tape into the tape drive. When you do, 268 the contents of the tape will be extracted into the 269 temporary directory, and the names of the files being 270 extracted will be printed. 271 272 After the tape has been extracted, to go the directory 273 containing the first distribution set you wish to 274 install. (Depending on how you made the tape, it's 275 probably a subdirectory of the temporary directory you 276 specified above.) Once there, run the "Set_tmp_dir" 277 command again, and accept its default answer by 278 hitting return at the prompt. 279 280 Use the "Extract" command to extract the distribution 281 set. For instance, if you're extracting the "base12" 282 set, use the command: 283 Extract base12 284 You will be asked if you wish the extraction to be 285 verbose. If you reply affirmatively, the name of each 286 file being extracted will be printed. 287 288 Repeat the previous two steps for each distribution 289 set you wish to install. Change to the set's 290 directory, run "Set_tmp_dir", and then run 291 "Extract <set_name>" to extract the set. 292 293 Once you are finished extracting all of the sets that 294 you wish to install, you should proceed to the 295 instructions below (after the last install medium 296 type-specific instructions), that explain how you 297 should configure your system. 298 299 To install via FTP or NFS: 300 The first thing you should do is pick a temporary 301 directory where the distribution files can be stored. 302 To do this, enter the command "Set_tmp_dir", and enter 303 the name of the temporary directory. (Don't forget 304 that your disk is mounted under /mnt; you should 305 probably pick a directory under /mnt/usr.) The 306 default is /mnt/usr/distrib. 307 308 Configure the SLIP interface, with the following 309 command sequence: 310 311 slattach -h -s <speed> tty00 312 ifconfig sl0 <my_ipaddr> <peer_ipaddr> 313 314 where "<speed>" is the network speed, and "<my_ipaddr>" 315 is the numeric IP address of the machine you are going 316 to install NetBSD/x68k, while "<peer_ipaddr>" is the 317 address of the peer machine connected with your machine. 318 You might have to configure the peer SLIP interface 319 with similar sequence (depending on the peer system). 320 321 For instance, the sequence 322 323 slattach -h -s 38400 tty00 324 ifconfig sl0 192.168.0.1 192.168.0.10 325 326 configures the SLIP interface for the network between 327 your machine (with IP address 192.168.0.1) and the peer 328 (192.168.0.10) with speed 38400 bps. Note that IP 329 addresses 192.168.*.* are the private IP addresses 330 described in RFC 1597. 331 332 If you are NFS-mounting the distribution sets, mount 333 them on the temporary directory with a command like: 334 335 mount -t nfs <serv_ipaddr>:<dist_dir> <tmp_dir> 336 337 where <serv_ipaddr> is the server's numeric IP address, 338 <dist_dir> is the path to the distribution files on 339 the server, and <tmp_dir> is the name of the local 340 temporary directory. 341 342 Once this is done, proceed as if you had loaded the 343 files from tape, changing to the appropriate 344 directories, running "Set_tmp_dir", and running 345 "Extract" as appropriate. 346 347 If you are retrieving the distribution sets using ftp, 348 change into the temporary directory, and execute the 349 command: 350 351 ftp <serv_ipaddr> 352 353 where <serv_ipaddr> is once again the server's numeric 354 IP address. Get the files with FTP, taking care to 355 use binary mode when transferring the files. 356 357 Once you have all of the files for the distribution 358 sets that you wish to install, you can proceed using 359 the instructions above, as if you had installed from a 360 floppy. (Note that as with the floppy install, if 361 you're short on disk space, you can transfer only one 362 set at a time, extract it, then delete it, to save 363 space.) 364 365 Once you have finished extracting all of the distribution sets 366 that you wish to install, and are back at the "#" prompt, you 367 are ready to configure your system. The configuration utility 368 expects that you have installed the "base12" and "etc12" 369 distribution sets. If you have not, you will not be able to 370 run it successfully (nor will you have a functional system, in 371 any case). To configure your newly-installed NetBSD system, 372 run the command "Configure". It will ask you for the system's 373 host name, domain name, and other network configuration 374 information. It will set up your configuration files and make 375 the device nodes for the newly-installed system. 376 377Kernel Installation: 378 379 Enter "halt" at the prompt to halt the system. When the 380 system is halted, remove the "inst12" floppy from the floppy 381 drive, and replace it with the NetBSD 1.2 kernel-copy floppy 382 that you previously booted from. Reboot with that floppy. 383 with that floppy. 384 385 Once again, you will be prompted to insert a file system 386 floppy. DO NOT replace the kernel-copy floppy, just hit any 387 key. 388 389 Again, While booting, you may see several warnings. You may 390 be warned that no swap space is present, that init(8) cannot 391 find /etc/rc, and that one or more databases with names like 392 "pwd.db" cannot be found. Do not be alarmed, as, again, these 393 are completely normal. Hit return at the prompt asking you 394 for a shell name. 395 396 You will be presented with a shell prompt, at which you should 397 enter the "copy_kernel" command. It will ask you what 398 partition to copy the kernel to, and you should reply with the 399 name of your root partition (e.g. sd0a or wd0a). 400 401 You will be asked if you are sure that you want to copy the 402 kernel. Reply affirmatively, and it will check the file 403 system on your root partition, mount it, and copy the kernel. 404 Once the kernel is copied, you should use "halt" to halt the 405 system. 406 407 Once the system is halted, remove the kernel-copy floppy from 408 the floppy disk drive, and hit any key to reboot. 409 410Congratulations, you have successfully installed NetBSD 1.2. When you 411reboot into NetBSD, you should log in as "root" at the login prompt. 412There is no initial password, but if you're using the machine in a 413networked environment, you should create yourself an account and 414protect it and the "root" account with good passwords. 415 416Some of the files in the NetBSD 1.2 distribution might need to be 417tailored for your site. In particular, the /etc/sendmail.cf file will 418almost definitely need to be adjusted, and other files in /etc will 419probably need to be modified, as well. If you are unfamiliar with 420UN*X-like system administration, it's recommended that you buy a book 421that discusses it. 422
