Bash Script to Handling gnokii Daemon

Dear, if we are working with gnokii, sometimes after a few minutes gnokii got hang-up or the sms can not stored (save to the database) or can not send (get from the database and sent it out). So, we must stop the gnokii processed daemon and then start it again. But, i think it's a waste time if we are always stop and start it again. And the worst thing is we didn't know when the gnokii got hang-up. Below is my own bash script to handle this situation.

# Check mysql.sock

MYSQL_SOCK_DIR="/opt/lampp/var/mysql";
MYSQL_SOCK_NAME="mysql.sock";

if [ ! -x "$MYSQL_SOCK_DIR/$MYSQL_SOCK_NAME" ]; then

echo "Can not found $MYSQL_SOCK_NAME in $MYSQL_SOCK_DIR"
echo "Please check if MySQL Server is running or change the location of $MYSQL_SOCK_NAME"
echo "Exiting..."

exit 1

fi

# ----------------------------------
# Linking mysql.sock
# ----------------------------------

MYSQL_SOCK_LINK_DIR="/var/run/mysqld";
MYSQL_SOCK_LINK_NAME="mysqld.sock";

if [ ! -x "$MYSQL_SOCK_LINK_DIR/$MYSQL_SOCK_LINK_NAME" ]; then

echo "Can not found $MYSQL_SOCK_LINK_NAME in $MYSQL_SOCK_LINK_DIR"
echo ""
echo "Trying to linking $MYSQL_SOCK_DIR/$MYSQL_SOCK_NAME to $MYSQL_SOCK_LINK_DIR/$MYSQL_SOCK_LINK_NAME ..."

/bin/ln -s "$MYSQL_SOCK_DIR/$MYSQL_SOCK_NAME" "$MYSQL_SOCK_LINK_DIR/$MYSQL_SOCK_LINK_NAME"

if [ ! -x "$MYSQL_SOCK_LINK_DIR/$MYSQL_SOCK_LINK_NAME" ]; then

echo "Failed to linking $MYSQL_SOCK_DIR/$MYSQL_SOCK_NAME to $MYSQL_SOCK_LINK_DIR/$MYSQL_SOCK_LINK_NAME"

exit 1

else

echo "Success to linking $MYSQL_SOCK_DIR/$MYSQL_SOCK_NAME to $MYSQL_SOCK_LINK_DIR/$MYSQL_SOCK_LINK_NAME"

fi

fi

# ----------------------------------
# gnokii smsd path
# ----------------------------------
SMSD_PATH="/usr/local"

while true
do
killall smsd >/dev/null 2>&1
sleep 3
$SMSD_PATH/sbin/smsd -u usersms -d sms -c localhost -m mysql >/dev/null 2>&1 &
sleep 1m
done

Sometimes the mysql.sock location is differ from the os/machine to other. So, in the script above i tried to find the mysql.sock location. If exist ignore it but if not exist create a link one. We need this mysql.sock because gnokii didn't work if gnokii didn't find the mysql socket. Of course this script useful when you want to combine gnokii with MySql database.

Hope this script giving you a new inspiration.
