# Building the OS
|
|
The Pi-KVM OS is based on Arch Linux ARM and contains all the required packages and configs for it to work. To build the OS you will need any Linux machine with a recent version of Docker (>= 1:19) with privileged mode enabled. (used for fdisk and some other commands, have a look through our Makefiles if you don't trust us :)). The build must be performed on the x86_64 host.
|
|
|
|
0. When starting with a clean OS (like **Ubuntu 20.04**, please not that Ubuntu 18.04 does not working) you need to install and configure docker (after adding your user to the docker group you must log out and log back in), as well as git and make.
|
|
```shell
|
|
[user@localhost ~]$ sudo apt-get install git make curl binutils -y
|
|
[user@localhost ~]$ curl -fsSL https://get.docker.com -o get-docker.sh
|
|
[user@localhost ~]$ sudo sh get-docker.sh
|
|
[user@localhost ~]$ sudo usermod -aG docker $USER
|
|
```
|
|
Re-login to apply the changes.
|
|
|
|
1. Git checkout the build toolchain:
|
|
```shell
|
|
[user@localhost ~]$ git clone https://github.com/pikvm/os
|
|
[user@localhost ~]$ cd os
|
|
```
|
|
|
|
2. Determine the target hardware configuration (platform):
|
|
* Choose the board: `BOARD=rpi4` for Raspberry Pi 4 or `BOARD=zerow`, `BOARD=rpi2`, `BOARD=rpi3` for other options.
|
|
* Choose the platform:
|
|
- `PLATFORM=v2-hdmi` for RPi4 or ZeroW with HDMI-CSI bridge.
|
|
- `PLATFORM=v0-hdmi` for RPi 2 or 3 with HDMI-CSI bridge and Arduino HID.
|
|
- `PLATFORM=v2-hdmiusb` for RPi4 with HDMI-USB dongle.
|
|
- `PLATFORM=v0-hdmiusb` for RPi 2 or 3 with HDMI-USB dongle and Arduino HID.
|
|
- Other options are for legacy or specialized Pi-KVM boards (WIP).
|
|
|
|
3. Create the config file `config.mk` for the target system. You must specify the path to the SD card on your local computer (this will be used to format and install the system) and the version of your Raspberry Pi and platform. You can change other parameters as you wish. Please note: if your password contains the # character, you must escape it using a backslash like `ROOT_PASSWD = pass\#word`.
|
|
```Makefile
|
|
[user@localhost os]$ cat config.mk
|
|
# rpi3 for Raspberry Pi 3; rpi2 for the version 2, zerow for ZeroW
|
|
BOARD = rpi4
|
|
|
|
# Hardware configuration
|
|
PLATFORM = v2-hdmi
|
|
|
|
# Target hostname
|
|
HOSTNAME = pikvm
|
|
|
|
# ru_RU, etc. UTF-8 only
|
|
LOCALE = en_US
|
|
|
|
# See /usr/share/zoneinfo
|
|
TIMEZONE = Europe/Moscow
|
|
|
|
# For SSH root user
|
|
ROOT_PASSWD = root
|
|
|
|
# Web UI credentials: user=admin, password=<this>
|
|
WEBUI_ADMIN_PASSWD = admin
|
|
|
|
# IPMI credentials: user=admin, password=<this>
|
|
IPMI_ADMIN_PASSWD = admin
|
|
|
|
# SD card device
|
|
CARD = /dev/mmcblk0
|
|
```
|
|
|
|
If you want to configure wifi (for ZeroW board for example) you must add these lines to `config.mk`:
|
|
```Makefile
|
|
WIFI_ESSID = "my-network"
|
|
WIFI_PASSWD = "P@$$word"
|
|
```
|
|
|
|
4. Build the OS. It may take about one hour depending on your Internet connection:
|
|
```shell
|
|
[user@localhost os]$ make os
|
|
```
|
|
|
|
5. Put SD card into card reader and install OS (**you should disable automounting beforehand**: `systemctl stop udisk2` or something like that):
|
|
```shell
|
|
[user@localhost os]$ make install
|
|
```
|
|
|
|
6. After installation remove the SD card and insert it into your RPi. Turn on the power. The RPi will try to get an IP address using DHCP on your LAN. It will then be available via SSH.
|
|
|
|
7. If you can't find the device's address, try using the following command:
|
|
```shell
|
|
[user@localhost os]$ make scan
|
|
```
|
|
|
|
8. **Only for v0**: [Flash the Arduino HID](flashing_hid.md).
|
|
|
|
9. Congratulations! Your Pi-KVM will be available via SSH (`ssh root@<addr>` with password `root` by default) and HTTPS (try to open in a browser the URL `https://<addr>`, the login `admin` and password `admin` by default). For HTTPS a self-signed certificate is used by default.
|
|
|
|
10. To change the root password use command `passwd` via SSH or webterm. To change Pi-KVM web password use `kvmd-htpasswd set admin`. As indicated on the login screen use `rw` to make the root filesystem writable, before issuing these commands. After making changes, make sure to run the command `ro`.
|
|
|
|
11. **27.08.2020 note about systemd**: the latest version of Arch Linux has a slightly broken systemd. The problem is that SSH to the Pi-KVM host may not work the first time, but the second or third. The Pi-KVM build environment contains a workaround for this problem: in the file `/etc/pam.d/system-login` line `-session optional pam_systemd.so` is commented. This does not have any negative impact on the PI-KVM functionality, but if you want to, after fixing the systemd (in a couple of months with the next update), you can uncomment this line.
