Hi,
I just unpacked my new hardware and I'm working with it.
This platform works with Linux (various versions of
OS are available in the Raspberry Pi official web site, also called "distros").The Micro SD memory card purchased with the hardware comes with the OS pre-installed. Mine was NOOBS. Thats fine if you wants to start "playing" with the system.
But I had a problem: I had no HDMI monitor available. But I had a laptop PC with Windows XP. So the only way to "watch" inside the system was through a VNC sessión. For this, first you have to configure the system entering with a SSH session (Secure SHell session). That is only possible if the OS has started. And this is impossible with the pre-installed NOOBS image card, and without a HDMI monitor and a keyboard.
So, the first of all was to delete the original SD card with the pre-installed NOOBS and install the RASPBIAN image. Follow
this steps for that.
Second: the SSH session. Be aware that the RPi has to be connected to a network with router
through the wired ethernet port for the first time (remember, you don't
have screen and you can't configure the Wifi connection). RASPBIAN has
enabled the DHCP in the wired ethernet port by default but you must to find the IP. For this
follow this steps. After that, and if you have a Raspbian release before November 2016, follow
this, step by step. (
¡¡Attention!!:
As of the November 2016 release, Raspbian has the SSH server disabled
by default. You will have to enable it manually. This is done using
raspi-config:
Enter
sudo raspi-config in the terminal, first select
Interfacing options, then navigate to
ssh, press
Enter and select
Enable or disable ssh server.
For headless setup, SSH can be enabled by placing a file named 'ssh',
without any extension, onto the boot partition of the SD card.)
Third: the VNC session.
To install the VNC server in Raspberry Pi (TightVNCserver for example) type the next in the SSH session:
sudo apt-get install tightvncserver
With this you have installed the VNC server software. But you have to run TightVNC Server in order to enter a password and an optional view-only password (you have to execute this step only once):
tightvncserver
I wanted my system to run the VNC server at boot (every time the RPi started). For this you have the next steps:
- Log into a terminal on the Pi as root:
- Navigate to the directory
/etc/init.d/:
cd /etc/init.d/
nano vncboot
- And write the following script inside:
### BEGIN INIT INFO
# Provides: vncboot
# Required-Start: $remote_fs $syslog
# Required-Stop: $remote_fs $syslog
# Default-Start: 2 3 4 5
# Default-Stop: 0 1 6
# Short-Description: Start VNC Server at boot time
# Description: Start VNC Server at boot time.
### END INIT INFO
#! /bin/sh
# /etc/init.d/vncboot
USER=root
HOME=/root
export USER HOME
case "$1" in
start)
echo "Starting VNC Server"
#Insert your favoured settings for a VNC session
sudo /usr/bin/vncserver :0 -geometry 1280x800 -depth 16 -pixelformat rgb565
;;
stop)
echo "Stopping VNC Server"
/usr/bin/vncserver -kill :0
;;
*)
echo "Usage: /etc/init.d/vncboot {start|stop}"
exit 1
;;
esac
exit 0
-
Save this file as
vncboot.
- Make this file executable:
chmod 755 vncboot
- Enable dependency-based boot sequencing:
update-rc.d /etc/init.d/vncboot defaults
- If enabling dependency-based boot sequencing was successful, you will see this:
update-rc.d: using dependency based boot sequencing
update-rc.d: error: unable to read /etc/init.d//etc/init.d/vncboot
- then try the following command:
update-rc.d vncboot defaults
- Reboot your Raspberry Pi and you should find a VNC server already started.
- Install a VNC viewer in your laptop OS.
With this steps you'll have a Raspberry Pi hardware with RASPBIAN installed and the VNC server running from boot.
Remember that if you want to start de RASPBIAN GUI you must run the "startx" command.
