65 | 32 | Dmitry Chernyak | h3. Задать пароль root |
66 | 32 | Dmitry Chernyak | |
67 | 32 | Dmitry Chernyak | Не делайте пароль слишком простым |
68 | 32 | Dmitry Chernyak | |
69 | 32 | Dmitry Chernyak | h3. Произвести разметку диска |
70 | 32 | Dmitry Chernyak | |
71 | 32 | Dmitry Chernyak | Инсталлятор предоставляет несколько типов автоматической разметки. |
72 | 32 | Dmitry Chernyak | |
73 | 32 | Dmitry Chernyak | Если вы планируете использовать программный RAID, выберите |
74 | 32 | Dmitry Chernyak | *2(4,6,8) disk with lvm* - в зависимости от количества жестких дисков. |
75 | 32 | Dmitry Chernyak | Для двух дисков используется raid1, для большего количества используется raid10. |
76 | 32 | Dmitry Chernyak | Raid10 - рекомендуемый уровень raid для использования с виртуализацией. |
77 | 32 | Dmitry Chernyak | |
78 | 32 | Dmitry Chernyak | Если вы используете аппаратный RAID, выберите |
79 | 32 | Dmitry Chernyak | *1 disk with lvm* |
80 | 32 | Dmitry Chernyak | |
81 | 32 | Dmitry Chernyak | Если у вас сервер с двумя типами дисков, например 2 диска SATA и 8 дисков SAS (сырых или под аппаратным RAID), мы рекомендуем произвести начальную установку полностью на SATA диски по шаблону *2 disk with lvm* и после настройки кластера, вручную добавить SAS-диски как дополнительную VG. |

314 | 32 | Dmitry Chernyak | |
315 | 32 | Dmitry Chernyak | После запуска, ВМ sci автоматически производит донастройку узлов кластера и становится для них сервером DNS. Операция занимает в среднем 5-10 минут. |

336 | 30 | Dmitry Chernyak | h2. Custom build ISO-image |
337 | 30 | Dmitry Chernyak | |
338 | 30 | Dmitry Chernyak | How to build your own ISO-image described here: [[BUILD-ISO]] (for experienced users, who want to include their own works to the distribution set) |
339 | 1 | Dmitry Chernyak | |
340 | 21 | Dmitry Chernyak | h2. Burn the ISO image |
341 | 5 | Владимир Ипатов | |
342 | 16 | Владимир Ипатов | You burn it with your favorite tool (for ex. - k3b). |
343 | 5 | Владимир Ипатов | |
344 | 5 | Владимир Ипатов | h2. Create bootable USB flash |
345 | 1 | Dmitry Chernyak | |
346 | 21 | Dmitry Chernyak | At present this option is only available when you build the ISO image yourself. |
347 | 21 | Dmitry Chernyak | Consult [[BUILD-ISO]]. |
348 | 5 | Владимир Ипатов | |
349 | 1 | Dmitry Chernyak | h2. Minimal System Requirements |
350 | 18 | Владимир Ипатов | |
351 | 18 | Владимир Ипатов | In real case you must choose hardware in according to real objectives. |
352 | 18 | Владимир Ипатов | For testing purposes minimal system requierements is: |
353 | 22 | Dmitry Chernyak | * 1.2 GB RAM |
354 | 18 | Владимир Ипатов | * 50GB HDD |
355 | 21 | Dmitry Chernyak | * 1Gbit ethernet for DRBD link (if you setup 2 or more nodes) |
356 | 21 | Dmitry Chernyak | * Hardware Virtualization support: Intel VT or AMD CPU (if you want to run the Windows instances) |
357 | 18 | Владимир Ипатов | |
358 | 1 | Dmitry Chernyak | h2. Install the system |
359 | 1 | Dmitry Chernyak | |
360 | 1 | Dmitry Chernyak | Install the system on two nodes (you may use only one node, but high |
361 | 1 | Dmitry Chernyak | availability capabilities will be unavailable). |
362 | 1 | Dmitry Chernyak | |
363 | 24 | Dmitry Chernyak | The installer will ask you: |
364 | 1 | Dmitry Chernyak | |
365 | 24 | Dmitry Chernyak | * The node's IP-address on the interlink. For ex.: 192.168.2.1(2) |
366 | 24 | Dmitry Chernyak | * The network mask. For ex.: 255.255.255.0 |
367 | 24 | Dmitry Chernyak | * The node's name. For ex.: gnt1(2) |
368 | 24 | Dmitry Chernyak | * The domain. For ex.: gnt.yourcompany.com |
369 | 24 | Dmitry Chernyak | * The default router's address (DO NOT specify if you use the separate network |
370 | 24 | Dmitry Chernyak | card for the interlink!) |
371 | 24 | Dmitry Chernyak | * The (new) DNS server's address on the interlink. For ex.: 192.168.1.254 |
372 | 24 | Dmitry Chernyak | * The root password |
373 | 24 | Dmitry Chernyak | * Chose one of predefined disk layouts or layout it manually. |
374 | 24 | Dmitry Chernyak | * Specify the disks on which yo want to place grub loader. Chose "md0" if you use |
375 | 24 | Dmitry Chernyak | the software RAID for the system partition. |
376 | 24 | Dmitry Chernyak | * Specify the additional kernel parameters (but usually you don't). |
377 | 24 | Dmitry Chernyak | |
378 | 15 | Владимир Ипатов | h3. Partitioning |
379 | 15 | Владимир Ипатов | |
380 | 22 | Dmitry Chernyak | During the installation you will be prompted to chose the one of predefined disk layouts |
381 | 22 | Dmitry Chernyak | useful for 1-8 disk nodes with or without the hardware RAID. |
382 | 22 | Dmitry Chernyak | |
383 | 22 | Dmitry Chernyak | If you chose the "manual layout" option then you should preserve following partitions on your nodes: |
384 | 1 | Dmitry Chernyak | |_.Name|_.Size|_.Purpose| |
385 | 1 | Dmitry Chernyak | |/|10G|Root partition for all node's data| |
386 | 1 | Dmitry Chernyak | |swap|1G|Swap space for Dom0 in calculation of 512Mb RAM| |
387 | 23 | Dmitry Chernyak | |xenvg|the rest or the another device|The LVM Volume, named 'xenvg', without any partitions| |
388 | 1 | Dmitry Chernyak | |
389 | 3 | Владимир Ипатов | The VG "xenvg" will be used as the default place for the instance's volumes. |
390 | 1 | Dmitry Chernyak | Also the "system-stuff" volume will be automatically created on xenvg (and mounted as /stuff). |
391 | 1 | Dmitry Chernyak | It serves for various big stuff like cdrom images, instance backups etc. |
392 | 1 | Dmitry Chernyak | |
393 | 1 | Dmitry Chernyak | At our own choice you may defer the creation of xenvg during the installation stage and to create it later. |
394 | 1 | Dmitry Chernyak | In this case any option with "no LVM" will be useful. |
395 | 22 | Dmitry Chernyak | |
396 | 23 | Dmitry Chernyak | NOTE: If you want to place your own partitions on xenvg, you should |
397 | 23 | Dmitry Chernyak | then exclude them from ganeti-managed volumes. (SEE [[SETUP]]). |
398 | 23 | Dmitry Chernyak | Simplest way is to name your partitions "sytem-*" because this |
399 | 23 | Dmitry Chernyak | pattern is excluded in SCI-CD by default. |
400 | 10 | Dmitry Chernyak | |
401 | 10 | Dmitry Chernyak | You may create more partitions or volume groups at your choice. |
402 | 1 | Dmitry Chernyak | |
403 | 1 | Dmitry Chernyak | h3. DNS server's address |
404 | 1 | Dmitry Chernyak | |
405 | 1 | Dmitry Chernyak | The cluster has it's own DNS server, which is also the 'approx' and |
406 | 1 | Dmitry Chernyak | 'puppet' server. At the [[SETUP]] stage, cluster DNS server can be linked |
407 | 1 | Dmitry Chernyak | to other DNS servers in the forwarding mode. |
408 | 1 | Dmitry Chernyak | |
409 | 23 | Dmitry Chernyak | The DNS server's address +must not+ be the address of the existing service. |
410 | 23 | Dmitry Chernyak | |
411 | 23 | Dmitry Chernyak | The cluster's domain name +must not+ be the name of the existing domain if |
412 | 23 | Dmitry Chernyak | local domain already exists (use subdomain, or completely different name). |
413 | 23 | Dmitry Chernyak | |
414 | 23 | Dmitry Chernyak | h2. Automatic post-installation changes |
415 | 23 | Dmitry Chernyak | |
416 | 23 | Dmitry Chernyak | During the installation phase, the postinst.sh script from the distro |
417 | 25 | Dmitry Chernyak | will apply over 40 system tweaks: [[POST-INSTALL]] |
418 | 23 | Dmitry Chernyak | |
419 | 23 | Dmitry Chernyak | The CD installation takes about 15 minutes per node. |
420 | 23 | Dmitry Chernyak | |
421 | 24 | Dmitry Chernyak | h2. The cluster is ready to setup |
422 | 23 | Dmitry Chernyak | |
