### END INIT INFO

### START LOCAL CONFIGURATION

# If you store this script in your Webware working directory

# and create a symlink to it as /etc/init.d/webkit_appname,

# it will try to guess your configuration parameters. Otherwise

# you need to hard code the path to the working directory here.

# You can make changes either directly here in the start script or

# you can also override the configuration in the Launch.py script.

# The location and name of the start sript:

START_SCRIPT="$0"

APP_NAME=`basename "$START_SCRIPT"`

if [ -h "$START_SCRIPT" ]; then

START_SCRIPT=`readlink -f "$START_SCRIPT"`

fi

# The location of the working directory:

WORK_DIR=`dirname "$START_SCRIPT"`

if [ "$WORK_DIR" = "/etc/init.d" ]; then

# Put hard coded path to working directory here:

WORK_DIR="."

fi

# Make sure to have the absolute path:

test -d "$WORK_DIR" || exit 5

WORK_DIR=`cd "$WORK_DIR" 2>/dev/null && pwd`

# The app server launch script:

APP_SERVER="$WORK_DIR/AppServer"

test -x "$APP_SERVER" || exit 5

# The app server configuration:

APP_SERVER_CONFIG="$WORK_DIR/Configs/AppServer.config"

test -f "$APP_SERVER_CONFIG" || exit 5

# The WebKit app server log file

# (you can set this in Launch.py as well):

#LOG_FILE="/var/log/$APP_NAME.log"

LOG_FILE="$WORK_DIR/Logs/webkit.log"

# Use this extension if you want to move the last log away

# (also consider using logrotate or something similar):

LOG_OLD=".old"

# The app server process id file

# (you can set this in Launch.py as well):

#PID_FILE="/var/run/$APP_NAME.pid"

PID_FILE="$WORK_DIR/webkit.pid"

# The user and group to run the app server

# (you can set this in Launch.py as well).

# If undefined, it will be the user and group

# running the start script (usually root).

# You should use a low-privilege account,

# like the work dir owner, wwwrun or nobody.

# This will use the owner of the AppServer script:

WEBWARE_USER=`stat -c "%U" "$APP_SERVER"`

WEBWARE_GROUP=`stat -c "%G" "$APP_SERVER"`

# Unset the following variable if you want to store the

# pid and log files as the user running the start script

# (usually root) or set it if you want these files to be

# written after switching to WEBWARE_USER:WEBWARE_GROUP.

LAUNCH_AS_WEBWARE="yes"

# Additional options -u or -O to be passed on to Python:

PYTHONOPTS=

# Additional libraries to be included in the Python path:

PYTHONPATH=
