— (current) | ||

| - | ====== HowTo create your own (RaspberryPi) image file ====== | ||
| - | It is written based upon how it works for the RPiv1, basically all archlinux images should follow the same concepts. You only need the correct Archlinux.tar file and qemu kernel file. The scripts that help during the creation can be found on the Github: [[https://github.com/PirateBox-Dev/arch_rpi_image_prepare|arch_rpi_image_prepare]]. | ||
| - | Software Requirements | ||
| - | * qemu with support for armv6 (for raspberry emulation) | ||
| - | * workin "sudo" environment | ||
| - | * losetup from util-linux 2.2 (at least) | ||
| - | * mkfs.vat | ||
| - | * mkfs.ext4 | ||
| - | * wget | ||
| - | * fdisk | ||
| - | * git | ||
| - | |||
| - | ===== Create the basic Image file ===== | ||
| - | Choose a working directory | ||
| - | |||
| - | mkdir -p ~/tmp | ||
| - | cd ~/tmp | ||
| - | git clone https://github.com/PirateBox-Dev/arch_rpi_image_prepare.git | ||
| - | cd arch_rpi_image_prepare/ | ||
| - | | ||
| - | Get latest service & motd file | ||
| - | |||
| - | cd staging_packages | ||
| - | wget https://raw.githubusercontent.com/PirateBox-Dev/PirateBoxScripts_Webserver/master/BuildScripts/piratebox.service | ||
| - | wget https://raw.githubusercontent.com/PirateBox-Dev/PirateBoxScripts_Webserver/master/BuildScripts/RPi_motd.txt | ||
| - | |||
| - | Prepare Bootstrap image, which runs the emulation. That image will be created based upon the latest archlinux-armv6 file | ||
| - | |||
| - | cd - | ||
| - | make create_arch_image | ||
| - | |||
| - | ===== Create an installation qemu image ===== | ||
| - | Create a woring qemu image once (only needed on first setup). | ||
| - | |||
| - | cd qemu-arm-rpi | ||
| - | cp ../raw_arch_image_file install_qemu_image | ||
| - | # now fix qemu specific stuff | ||
| - | sudo losetup -f -P install_qemu_image | ||
| - | mkdir tmp | ||
| - | sudo mount /dev/loop0p2 tmp | ||
| - | sudo sed -i 's|^/dev/mmcblk0p1|/dev/mmcblk0p1|' tmp/etc/fstab | ||
| - | sudo umount tmp | ||
| - | | ||
| - | | ||
| - | Now you need X. Startup the qemu instance. it will mount the raw_arch_image_file as a 2nd device. | ||
| - | |||
| - | ./run_qemu.sh | ||
| - | |||
| - | __**HINT:**__ The emulation may have a different keyboard setting. | ||
| - | The first bootup usually fails, because the fstab is not correct. After the bootup failed, login in maintenance mode using root-password "root", then run the following command: | ||
| - | |||
| - | echo "" > /etc/fstab | ||
| - | reboot | ||
| - | |||
| - | ===== Prepare the imagefile for distribution ===== | ||
| - | (Re)Start the emulation: | ||
| - | |||
| - | ./run_qemu.sh | ||
| - | |||
| - | After bootup, login using username: root ; password: root | ||
| - | |||
| - | __**HINT:**__ To leave the emulation with the mouse, press CTRL+ALT | ||
| - | |||
| - | Enable network inside the emulation | ||
| - | |||
| - | dhcpcd eth0 | ||
| - | |||
| - | Start prepare the image.. | ||
| - | |||
| - | sh /prebuild/staging/install_packages.sh | ||
| - | |||
| - | As there is currently no pacman Package for PirateBox run: | ||
| - | |||
| - | pacman --noconfirm -r /mnt/image -S python2 lighttpd bash iw hostapd dnsmasq bridge-utils avahi wget wireless_tools netctl perl iptables zip unzip cronie net-tools | ||
| - | # for development version of PirateBox & LibraryBox additional packages: pacman --noconfirm -r /mnt/image -S radvd proftpd php php-cgi php-sqlite lftp imagemagick php-gd | ||
| - | |||
| - | ==== Further configuration of the image file ==== | ||
| - | |||
| - | Prepare for chroot into the environment | ||
| - | |||
| - | mount -o bind /run /mnt/image/run | ||
| - | mount -o bind /dev /mnt/image/dev | ||
| - | mount -o bind /proc /mnt/image/proc | ||
| - | |||
| - | Change root environment.... | ||
| - | |||
| - | chroot /mnt/image /bin/bash | ||
| - | |||
| - | === Do customization for running PirateBox === | ||
| - | |||
| - | systemctl enable sshd | ||
| - | ln /usr/bin/python2 /usr/bin/python | ||
| - | cd root | ||
| - | wget http://downloads.piratebox.de/piratebox-ws_current.tar.gz | ||
| - | tar xzf piratebox-ws_current.tar.gz | ||
| - | cp -rv piratebox/piratebox /opt | ||
| - | groupadd nogroup && usermod -a -G nogroup nobody | ||
| - | /opt/piratebox/bin/install_piratebox.sh /opt/piratebox/conf/piratebox.conf part2 | ||
| - | /opt/piratebox/bin/install_piratebox.sh /opt/piratebox/conf/piratebox.conf imageboard | ||
| - | cp /prebuild/staging/piratebox.service /etc/systemd/system | ||
| - | cp /prebuild/staging/RPi_motd.txt /etc/motd | ||
| - | |||
| - | leave chroot environment | ||
| - | |||
| - | exit | ||
| - | |||
| - | Do some cleanup on the image file | ||
| - | |||
| - | pacman --noconfirm -r /mnt/image -Scc | ||
| - | |||
| - | Tidy up and exit the qemu-vm | ||
| - | |||
| - | umount -R /mnt/image | ||
| - | reboot | ||
| - | |||
| - | Then pack the file | ||
| - | |||
| - | zip -9 <zip filename> raw_arch_image_file | ||
| - | |||
| - | ===== Troubleshooting ===== | ||
| - | |||
| - | If you encounter the following error | ||
| - | |||
| - | /dev/loop0p1: No such file or directory | ||
| - | Makefile:65: recipe for target 'format_p1' failed | ||
| - | |||
| - | Then do | ||
| - | |||
| - | make free_lo | ||
| - | |||
| - | Then try again... sometimes the kernel isn't fast enough on the first try... | ||
