Revision as of 15:32, 19 December 2013

Gambaran umum tiga langkah cara instalasi:

  • Boot board dengan OpenWrt dari jaringan (netboot): server DHCP dan TFTP dibutuhkan di host.
  • Instal OpenWrt ke internal flash dengan wget2nand: server HTTP atau FTP dibutuhkan di host.
  • Reboot dengan instalasi baru, lakukan konfigurasi dll.

Netboot

bootloader dari RB433 mampu untuk meload image dalam format elf melalui BOOTP ke RAM dan menjalankannya.


Build Image

Kita perlu mendownload OpenWrt trunk. Di menuconfig pilih:

  • Target System: Atheros AR7xxx/AR9xxx
  • Subtarget: Devices with NAND flash (mostly Mikrotik)
  • Target Images: ramdisk (juga tar.gz jika kita berencana untuk menginstalasi secara permanen dengan image yang sama).

Buat versi ram disk. Jika sudah ada binary-nya, buat symlink atau copy ke directory tftp-root, misalnya. 

sudo mkdir -p /tftpboot
# sudo ln -sf $(HOME)/openwrt/rb433uah-netboot/bin/ar71xx/openwrt-ar71xx-nand-vmlinux-initramfs.elf /tftpboot/openwrt.elf
cp openwrt-ar71xx-mikrotik-vmlinux-initramfs.elf /tftpboot/openwrt.elf
chmod -Rf 777 /tftpboot/

Setup Host

Kita membutuhkan server BOOTP dan TFTP di host, yang paling mudah adalah menggunakan dnsmasq, karena dapat memberikan dua layanan tersebut sekaligus. Install menggunakan perintah: 

sudo apt-get install dnsmasq

Ubah dnsmasq.conf 

vi /etc/dnsmasq.conf

Misalnya menggunakan parameter 

interface=eth0
dhcp-range=192.168.1.50,192.168.1.150,12h
# dhcp-host=00:0C:42:XX:XX:XX,192.168.6.101 # ubah menggunakan MAC board Mikrotik yang kita gunakan
dhcp-host=00:0C:42:72:E0:41,192.168.1.100
enable-tftp
tftp-root=/tftpboot
dhcp-boot=/tftpboot/openwrt.elf,boothost,192.168.1.6

Restart dnsmasq 

/etc/init.d/dnsmasq restart

Jika diperlukan kita dapat menset IP dari interface secara manual, misalnya: 

sudo ip addr add 192.168.1.6/24 dev eth0
sudo ifconfig eth0 192.168.1.6

Setup Target

Install 

apt-get install screen

Sambunkan kabel serial. Jalankan di terminal 

screen /dev/ttyUSB0 115200,cs8,-ixon,-ixoff

Langkah yang perlu dilakukan:

  • Sambungkan ke serial port dengan kabel serial (115200, 8N1).
  • Tekan tombol apapun setelah board dinyalakan.
  • Tekan o to change the boot device
  • Tekan e to boot from ethernet in the future.
  • Tekan x untk keluar dari setup (-o-e-x is needed only once, the boot method is saved in non-volatile memory)
  • CATATAN: untuk mengembalikan boot ke NAND tekan -o-o-x

Akan keluar

Instalasi Permanen

Untuk melakukan instalasi permanen, kita perlu masuk menggunakan netboot. Kita tidak bisa me-reflash dari instalasi OpenWRT sebelumnya, flash hanya bisa dilakukan melalui netboot.

Target Image

Buat target Image Untuk flash NAND Mikrotik RB433. Pastikan make menuconfig ada 

Target System > Atheros AR7xxx/AR9xxx
Subtarget > Mikrotik devices with NAND flash
Target Profile > Atheros WiFi (ath5k) 
Target Images >
       cpio.gz 
       tar.gz
       ext4
       jffs2
       squashfs
       GZip images

File yang dperlukan untuk me-flash NAND adalah

  • openwrt-ar71xx-nand-rootfs.tar.gz
  • openwrt-ar71xx-nand-vmlinux-lzma.elf

Untuk OpenWRT versi baru kemungkinan adalah

  • openwrt-ar71xx-mikrotik-Ath5k-rootfs.tar.gz
  • openwrt-ar71xx-mikrotik-vmlinux-lzma.elf

Supaya aman sebaiknya semua file berikut di letakan di web

  • openwrt-ar71xx-mikrotik-Ath5k-rootfs.tar.gz
  • openwrt-ar71xx-mikrotik-rootfs.cpio.gz
  • openwrt-ar71xx-mikrotik-root.jffs2-128k
  • openwrt-ar71xx-mikrotik-root.jffs2-256k
  • openwrt-ar71xx-mikrotik-root.jffs2-64k
  • openwrt-ar71xx-mikrotik-root.squashfs
  • openwrt-ar71xx-mikrotik-root.squashfs-64k
  • openwrt-ar71xx-mikrotik-vmlinux.bin
  • openwrt-ar71xx-mikrotik-vmlinux.elf
  • openwrt-ar71xx-mikrotik-vmlinux.gz
  • openwrt-ar71xx-mikrotik-vmlinux.lzma
  • openwrt-ar71xx-mikrotik-vmlinux-lzma.elf


Save your RouterOS license key

If you have access to the MikroTik's Winbox software, you can export the license file from System→Licence, as stated on the RouterBoard 411 page.

Otherwise, boot RouterOS and export the key to a file: 

/system license output

Then list the files on your device to see which file the .key file was saved: 

/file print

On a fresh install, the key file should be #1 (or #0 on a RB433UAH); to open the editor with file #1, type: 

/file edit 1 value-name=contents

Then copy-paste the text in a file on your computer. The differences between the obtained key file and a key exported with Winbox are that the SoftwareID line is not present in the latter, and there are no empty lines, so you should probably delete all the empty lines in your file prior to import it for a new installation; the SoftwareID line should not bother the installer (untested).

Erase the NAND Flash

Jika kita ingin menginstalasi OpenWRT secara perman ke NAND flash. Kita perlu memformat NAND flash untuk membuang semua RouterOS.

Caranya:

  • Sambung melalui kabel serial.
  • Tekan keyboard setelah RB433 nyala.
  • Tekan e dan ketik yes untuk memformat flash dari bootloader.


Setup Apache Web Server Lokal

Setup Apache Web Server Lokal. Kemudian sebagai user biasa yang mengcompile OpenWRT, lakukan: 

rm /var/www/index*
cp ~/openwrt.trunk/trunk/bin/ar71xx/* /var/www
sudo chmod 777 /var/www
mv openwrt-ar71xx-mikrotik-Ath5k-rootfs.tar.gz openwrt-ar71xx-mikrotik-rootfs.tar.gz

Jika perintah mv di atas tidak dilakukan, maka

Install OpenWrt ke NAND Flash

Lakukan:

  • netboot
  • Tekan ENTER Untuk memperoleh shell.
  • Lakukan
ping 192.168.1.6

Pastikan ada sambungan, jika tidak kadang kala bisa di atasi dengan mematikan br-lan 

ifconfig br-lan down

Kemudian 

wget2nand http://192.168.1.6

Script ini akan melakukan transfer melalui br-lan, dengan tampilan

Image written, you can now reboot.  Remember to change the boot source to Boot from Nand

Ubah Boot Source

  • Sambungkan ke serial port dengan kabel serial (115200, 8N1).
