* This guide is based on a Debian distribution.

* The euphorik root directory is "/var/euphorik" (for example)

* All line beginning with a '$' is a command line in the *System shell*

* All line beginning with a '>' is a command line in the *Erlang shell*

* You can start euphorik in development mode with "$cd /var/euphorik/tools ; ./start_yaws.sh"

# Build Euphorik

## $cd /var/euphorik/modules ; make

# Install Yaws

## $apt-get install yaws

# Configure Yaws (for production use)

## The virtual server looks like that in "/etc/yaws/conf.avail/euphorik.conf".<pre>

   ebin_dir = /var/euphorik/modules/ebin

   include_dir = /var/euphorik/modules/include

   <server localhost>

      port = 8081

      listen = 0.0.0.0

      docroot = /var/euphorik

      allowed_scripts = [yaws]

      appmods = <request, euphorik_requests>

      start_mod = euphorik_daemon

   </server>

</pre>

## Make a symlink in "conf.d" with "$cd /etc/yaws/conf.d/ ; ln -s "/etc/yaws/conf.avail/euphorik.conf"

## Edit the file '/etc/init.d/yaws' and substitue the following line 'script="$DAEMON -I $YAWS_ID $@"' by this one '$DAEMON --sname yaws --mnesiadir \"/var/euphorik/BD\" -I $YAWS_ID $@'

# Initialize the data base

## The directory "/var/euphorik/BD" must be writable for the yaws user

## Stop Yaws (in root)

### $/etc/init.d/yaws stop

## Launch an Erlang Node

### $cd /var/euphorik/module/ebin

### $erl -sname yaws -mnesia dir /euphorik/var/BD

## Load the module

### >l(euphorik_bd_admin).

## Make the DB

### >euphorik_bd_admin:create().

## Start Yaws : $/etc/init.d/yaws start
