| + | |
| − | | + | |
| − | ===Enable autostart===
| + | |
| − | | + | |
| − | ====Display of IP====
| + | |
| − | | + | |
| − | Start app to display IP on Regbot display, log CPU temperature and synchronize hostname
| + | |
| − | | + | |
| − | Make an on-rebbot script in the home directory
| + | |
| − | | + | |
| − | cp ~/svn/robobot/setup/on_reboot.bash ~/
| + | |
| − | | + | |
| − | This file is something like:
| + | |
| − | | + | |
| − | #!/bin/bash
| + | |
| − | # script to start applications after a reboot
| + | |
| − | #
| + | |
| − | # run the app to show IP of raspberry on the Teensy display.
| + | |
| − | mkdir -p /home/local/svn/log
| + | |
| − | cd /home/local/svn/log
| + | |
| − | # save the last reboot date
| + | |
| − | echo "Rebooted" >> rebootinfo.txt
| + | |
| − | date >> rebootinfo.txt
| + | |
| − | ../robobot/ip_disp/build/ip_disp &
| + | |
| − | # save PID for debugging
| + | |
| − | echo "ip_disp started with PID:" >> rebootinfo.txt
| + | |
| − | pgrep -l ip_disp >> rebootinfo.txt
| + | |
| − | exit 0
| + | |
| − | | + | |
| − | Use crontab to run this script at reboot
| + | |
| − | | + | |
| − | crontab -e
| + | |
| − | | + | |
| − | Add this line at the end:
| + | |
| − | @reboot /home/local/on_reboot.bash
| + | |
| − | | + | |
| − | ====Hostname update====
| + | |
| − | | + | |
| − | A script updates the Raspberry Pi hostname, with the name in ''~/svn/log/robotname''.
| + | |
| − | The script ''rename_host.bash'' is:
| + | |
| − | #!/bin/bash
| + | |
| − | hn=`hostname`
| + | |
| − | f="/home/local/svn/log/robotname"
| + | |
| − | if [ -f $f ];
| + | |
| − | then
| + | |
| − | nn=`cat $f`
| + | |
| − | yy= $(expr length $nn)
| + | |
| − | if [ $yy -gt 2 ];
| + | |
| − | then
| + | |
| − | if [ $hn != $nn ];
| + | |
| − | then
| + | |
| − | hostnamectl set-hostname $nn
| + | |
| − | # seems like /etc/hosts is not updated, but /etc/hostname is
| + | |
| − | sed -i "s/$hn/$nn/g" /etc/hosts
| + | |
| − | else
| + | |
| − | echo Same hostname, all is fine.
| + | |
| − | fi
| + | |
| − | fi
| + | |
| − | else
| + | |
| − | echo "File >" $f "< not found."
| + | |
| − | fi
| + | |
| − | | + | |
| − | The script needs to be run as root, it is therefore set to run as part of the boot process.
| + | |
| − | | + | |
| − | Create the script in /etc/init.d
| + | |
| − | | + | |
| − | sudo nano /etc/init.d/host_rename.sh
| + | |
| − | | + | |
| − | Enter the following lines into the new file
| + | |
| − | | + | |
| − | #!/bin/bash
| + | |
| − | bash /home/local/svn/robobot/setup/rename_host.bash
| + | |
| − | | + | |
| − | Make the file executable and add it to run-level 2 (before networking is started)
| + | |
| − | | + | |
| − | sudo chmod +x /etc/init.d/host_rename.sh
| + | |
| − | sudo ln -s /etc/init.d/host_rename.sh /etc/rc2.d/S99host_rename
| + | |
| − | | + | |
| − | The script is then executed when the Raspberry boots, and if the hostname does not match that of the Teensy, then the hostname is modified.
