If you wish to add a new service to start when the machine boots you should add the script to the directory /etc/init.d/. Many of the scripts already present in that directory will give you an example of the kind of things that you can do.

Here’s a very simple script which is divided into two parts, code which always runs, and code which runs when called with “start” or “stop”.

#! /bin/sh
# /etc/init.d/routines
#
 
# Some lines that run always
rm /var/lock/routines
touch /var/lock/routines
 
 
# Carry out specific functions when asked to by the system
case "$1" in
  start)
    echo "Starting script routines "
    echo "Could do more here"
    ;;
  stop)
    echo "Stopping script routines"
    echo "Could do more here"
    ;;
  *)
    echo "Usage: /etc/init.d/routines {start|stop}"
    exit 1
    ;;
esac
 
exit 0

Once you’ve saved your file into the correct location make sure that it’s executable by running “chmod 755 /etc/init.d/routines”.

Then you need to add the appropriate symbolic links to cause the script to be executed when the system goes down, or comes up.

The simplest way of doing this is to use the Debian-specific command update-rc.d:

root@skx:~# update-rc.d blah defaults
 Adding system startup for /etc/init.d/routines...
   /etc/rc0.d/K20routines -> ../init.d/routines
   /etc/rc1.d/K20routines -> ../init.d/routines
   /etc/rc6.d/K20routines -> ../init.d/routines
   /etc/rc2.d/S20routines -> ../init.d/routines
   /etc/rc3.d/S20routines -> ../init.d/routines
   /etc/rc4.d/S20routines -> ../init.d/routines
   /etc/rc5.d/S20routines -> ../init.d/routines

If you wish to remove the script from the startup sequence in the future run:

root@skx:/etc/rc2.d# update-rc.d -f  routines remove
update-rc.d: /etc/init.d/routines exists during rc.d purge (continuing)
 Removing any system startup links for /etc/init.d/routines ...
   /etc/rc0.d/K20routines
   /etc/rc1.d/K20routines
   /etc/rc2.d/S20routines
   /etc/rc3.d/S20routines
   /etc/rc4.d/S20routines
   /etc/rc5.d/S20routines
   /etc/rc6.d/K20routines

This will leave the script itself in place, just remove the links which cause it to be executed.

You can find more details of this command by running “man update-rc.d”.

bzip2 -cd amrwb-7.0.0.3.tar.bz2 | tar xvf -
tar zxvf libtheora-1.0beta3.tar.gz

We need a codec directory

mkdir /usr/local/lib/codecs/

Install Ruby on Rails, subversion & ncurses 

apt-get install subversion ruby libcurses-ruby

Run some SVN queries 

svn checkout svn://svn.mplayerhq.hu/ffmpeg/trunk ffmpeg
svn checkout svn://svn.mplayerhq.hu/mplayer/trunk mplayer
cd /usr/local/src/mplayer
svn update

Copy Codecs for mplayer 

mkdir /usr/local/lib/codecs
mv /usr/local/src/essential-20071007/* /usr/local/lib/codecs/
chmod -R 755 /usr/local/lib/codecs/

We also need to secure the tmp directory

mkdir /usr/local/src/tmp
chmod 777 /usr/local/src/tmp
export TMPDIR=/usr/local/src/tmp

Install lame 

cd /usr/local/src/lame-3.97
./configure
make && make install

Install libogg 

cd /usr/local/src/libogg-1.1.3
./configure && make && make install

Install libvorbis 

cd /usr/local/src/libvorbis-1.2.0
./configure && make && make install

Install flvtool2 

cd /usr/local/src/flvtool2-1.0.6/
ruby setup.rb config
ruby setup.rb setup
ruby setup.rb install

Install mplayer & mencoder 

cd /usr/local/src/mplayer
./configure --enable-jpeg
make && make install

Install AMR (for 3gp conversion) 

cd /usr/local/src/amrnb-7.0.0.2
./configure
make && make install
cd /usr/local/src/amrwb-7.0.0.3
./configure
make && make install

Install libtheora (for ogg video encoding) 

cd /usr/local/src/libtheora-1.0beta3
./configure
make && make install

Install ffmpeg

Debian Etch and Ubuntu 8.04 users please use the following configure command:

cd /usr/local/src/ffmpeg/
./configure --enable-libmp3lame --enable-libvorbis --disable-mmx --enable-shared --enable-libamr-nb --enable-libamr-wb --enable-nonfree --enable-libtheora

Ubuntu 7.06 users please use the following configure command:

./configure --enable-libmp3lame --enable-libogg --enable-libvorbis --disable-mmx --enable-shared --enable-libamr-nb --enable-libtheora

Now run these commands:

make
make install
ln -s /usr/local/lib/libavdevice.so.52 /usr/lib/libavdevice.so.52
ln -s /usr/local/lib/libavformat.so.52 /usr/lib/libavformat.so.52
ln -s /usr/local/lib/libavcodec.so.52 /usr/lib/libavcodec.so.52
ln -s /usr/local/lib/libavutil.so.49 /usr/lib/libavutil.so.49
ln -s /usr/local/lib/libmp3lame.so.0 /usr/lib/libmp3lame.so.0
ln -s /usr/local/lib/libavformat.so.51 /usr/lib/libavformat.so.51
ln -s /usr/local/lib/libamrnb.so.3 /usr/lib/libamrnb.so.3
ln -s /usr/local/lib/libamrwb.so.3 /usr/lib/libamrwb.so.3

Install ffmpeg-php 

cd /usr/local/src/ffmpeg-php-0.5.0/
phpize
./configure
make
make install

You now need to add the new ffmpeg-php module to the php.ini file

vim /etc/php5/apache2/php.ini
extension=ffmpeg.so (add this line to the end of the file)

Restart & done 

/etc/init.d/apache2 force-reload

İf you want to change debian’s system language you must follow these steps;

sudo apt-get update
sudo apt-get install debconf
sudo dpkg-reconfigure locales

Or you could add something like the following lines to /etc/environment

LANG=”en_US.UTF-8″
LANGUAGE=”en_US:en”

If you want different locales for different users, you can add that to their
.bashrc files

Here’s some links that touch on what you’re looking for:
