These are installation notes for getting the mini-box LCD appliance up and running with Ubuntu Server 32-bit 8.10 (Intrepid) wth an Atom processor and making use of the menuing system.
Ubuntu
Although we will intend to run this box without a monitor for the moment we will plug in the monitor to install Ubuntu from a USB-CDROM. Make sure the BIOS is configured to boot from the CD-ROM. Also, under Peripheral Devices you will need to enable all legacy support (or it will hang on installation).
LCD Menu
First create a user 'lcdmenu' that can't login:
sudo adduser --disabled-login --gecos lcdmenu
This applies to LCD Menu 1.0 which is not packaged yet. Download it in whatever way makes you happy and install it to /home/lcdmenu/bin (once you have made the directory).
Now edit the "sudoers" file by running:
sudo visudo
and add this line to grant the lcdmenu user limited access to system functions
%lcdmenu ALL=NOPASSWD: /sbin/shutdown, /etc/init.d/apache2, /etc/init.d/mysql, /usr/bin/mysqldump, /usr/bin/apt-get
Create a "backup" user in mysql with localhost only access and no password which can lock and select all tables
mysql -u root -p mysql> GRANT SELECT,LOCK TABLES on *.* TO backup@localhost IDENTIFIED BY PASSWORD ; mysql> quit;
Now we want it to setup to run periodically:
sudo crontab -u lcdmenu -e * * * * * /home/lcdmenu/bin/lcdmenu_check.sh
Automount
The LCD Menuing system has a "backup MySQL database to a flash drive" feature. Since we will not be using GNOME, we will need a USB automounter:
sudo apt-get install usbmount
Then edit the file /etc/usbmount/usbmount.conf and add "vfat" to the FILESYSTEMS e.g:
FILESYSTEMS="ext2 ext3 vfat"
then make sure the FS_MOUNTOPTIONS line has at least:
FS_MOUNTOPTIONS="gid=lcdmenu,dmask=0007,fmask=0117"
Software RAID
Network Status
The MAC Address, to configure your router, can be obtained from the LCD Menu:
>F1:Server Status >F2:Network Status >F3:MAC Address
Similarly, if you have plugged the server into a network with DHCP, you can get the IP Address:
>F1:Server Status >F2:Network Status >F3:MAC Address
Webmin
See me or just cut and paste:
sudo aptitude install perl libnet-ssleay-perl openssl libauthen-pam-perl libpam-runtime libio-pty-perl libmd5-perl wget http://garr.dl.sourceforge.net/sourceforge/webadmin/webmin_1.441_all.deb sudo dpkg -i webmin_1.441_all.deb
Browse to:
https://your-server-ip:10000/
and login as the user you created on Ubuntu installation.
