Obsah
Zakladni cil
- Nainstalovat debian testing na Alix-APU s SSD diskem a pripravit navod pro ostatni
- Diky tomu ze hardware nove APU desky je pomerne vykony, neni problem na nem rozbehnout prome klasickeho routovani(ospf) i dalsi sluzby(DNS, mail, jednoduchy web, statistiky prenosu...)
- Procesor je x86(konkretne architektura amd64), 2xcore 1GHz
- Jde pripojit SSD disk pres mSATA, nebo klasicky disk pres SATA - idealni na klasickou instalaci linuxu(zadne omezeni readonly CF).
- Klasicky disk pres SATA se nevejde do krabicky, tak jsem zvolil mSATA od pcengines s kapacitou 16GB
- V pripade potreby neni problem koupit vetsi mSATA napr. u alza.cz - az 500GB
- Cely navod je hodne detailni, experti se snad neurazi :-). Pro zkusenejsi: Jedina vetsi slozitost spociva v nastaveni bootloaderu a kernelelu tak aby produkoval vystup na RS323. Ostatni je standardni instalace linuxu(debianu).
Instalace HW
- Nalepit chladic(kus plechu) podle navodu vyrobce, hlinikova krabicka pomaha taky chladit
- Zastrcit SSD disk
- soupnout do krabicky
Pripojeni pres seriovou linku
- APU nema grafickou kartu, takze je potreba pripojit se seriovou linkou.
- Pro ty mene stastnejsi z nas kteri uz nemaji v notebooku seriovy port je potreba neco jako: USB->RS232 a null-modem cable null-modem kabel
- Nastaveni rychlosti serioveho portu 115200 8N1
- Nalezeni spravneho cisla COM portu prirazeneho prevodniku. viz screenshot
- Pres putty viz screenshot
- Pres hyperterminal viz. screenshot
Pripraveni instalacniho USB
Nastroj na pripraveni instalacniho USB
- Pavkriz: link na nastroj, ktery umi pod linuxem pripravit instalacni image pro USB flasku, ze ktere se to pak samo nainstaluje na SSD https://github.com/ssinyagin/pcengines-apu-debian-cd
Rucni pripraveni instalacniho USB v Linuxu
- Vychazel jsem z navodu | 4.3.3. Manually copying files to the USB stick — the flexible way
- Staci jakakoliv USB flashka s velikosti >>1GB
- Predpokladam ze flashka je naformatovana na fat16 a oznacena flagem bootable. V pripade ze tomu tak neni, libovolnym nastrojem nastavime(cfdisk, fdisk,...)
- Pro kontrolu overime(v mem pripade 4GB USB flashka)
NPSWorkstation1:~# fdisk -l /dev/sdh Disk /dev/sdh: 4110 MB, 4110188544 bytes 67 heads, 14 sectors/track, 8558 cylinders, total 8027712 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Device Boot Start End Blocks Id System /dev/sdh1 * 62 8027711 4013825 6 FAT16
- Nainstalujeme bootloader. Debian pouziva pro instalacni USB syslinux(jinak by sel pouzit i grub nebo lilo). Flashka nesmi byt primountovana.
NPSWorkstation1:~# syslinux /dev/sdh1
- Primountujeme USB flashku
mount /dev/sdh1 /mnt/temp
- Stahneme z hd-media soubory vmlinuz a initrd.gz
- Stahneme z cdimage soubor debian-testing-i386-CD-1.iso
- Vsechny 3 soubory nakopirujeme na USB flasku
- Vytvorime na USB flashce soubor syslinux.cfg s nasledujicim obsahem:
NPSWorkstation1:/mnt/temp# cat syslinux.cfg serial 0 115200 default vmlinuz append initrd=initrd.gz console=tty0 console=ttyS0,115200n8 prompt 1
- Obsah instalacni USB flasky by mel vypadat takto:
NPSWorkstation1:/mnt/temp# ll total 673592 -rwxr-xr-x 1 root root 679477248 Apr 21 09:17 debian-testing-amd64-CD-1.iso -rwxr-xr-x 1 root root 7344491 Apr 22 11:28 initrd.gz -r-xr-xr-x 1 root root 32768 Apr 22 11:28 ldlinux.sys -rwxr-xr-x 1 root root 103 Apr 23 08:41 syslinux.cfg -rwxr-xr-x 1 root root 110 Apr 22 16:11 syslinux.cfg~ -rwxr-xr-x 1 root root 2887760 Apr 22 11:29 vmlinuz NPSWorkstation1:/mnt/temp#
- USB flaska je ted pripravena. Staci pripojit seriovy kabel k APU, pripojit USB flasku, zapnout napajeni a instalovat :-)
=== Rucni pripraveni instalacniho USB v prostredi Windows
Vlastni instalace Debianu
- TODO... Klasicka instalace
Tipy
- zkontrolovat FD/HD pres mii-tool a ethtool
Performance testing
- vsechny testy bez NATu, ipv4
- test pres iptraf TCP halfduplex v podstate cely 1Gbit/s
- test pres iptraf TCP fullduplex zvladne tak kolem 500Mbit/s, cca 20 000pps. Pravdepodobne uz nestihaji irq/s --> Mozny tunning pres irqbalance a podobne??
Pripojit mobilku s androidem jako zdroj internetu
- Na androidu Nastaveni --> Sdileni pripojeni --> enable sdileni pripojeni pres USB
- Na APU
