Executing Microsoft SQL Server Stored Procedure from PHP on Linux

In a real production environment, we would like Apache running as a service, meaning that whenever our machine starts-up, these services will startup automatically.  Copy and paste the following script and save it as httpd in the /etc/init.d folder.

#!/bin/bash
#
# Startup script for the Apache Web Server
#
# chkconfig: - 85 15
# description: Apache is a World Wide Web server.  It is used to serve \
#        HTML files and CGI.
# processname: httpd
# pidfile: /var/run/httpd.pid
# config: /usr/local/apache2/conf/httpd.conf

# Source function library.
. /etc/rc.d/init.d/functions

# This will prevent initlog from swallowing up a pass-phrase prompt if
# mod_ssl needs a pass-phrase from the user.
INITLOG_ARGS=""

# Path to the Apachectl script, server binary, and short-form for messages.
apachectl=/usr/local/apache2/bin/apachectl
httpd=/usr/local/apache2/bin/httpd
prog=httpd
RETVAL=0

# The semantics of these two functions differ from the way Apachectl does
# things -- attempting to start while running is a failure, and shutdown
# when not running is also a failure.  So we just do it the way init scripts
# are expected to behave here.
start() {
        echo -n $"Starting $prog: "
        daemon $httpd $OPTIONS
        RETVAL=$?
        echo
        [ $RETVAL = 0 ] && touch /var/lock/subsys/httpd
        return $RETVAL
}
stop() {
 echo -n $"Stopping $prog: "
 killproc $httpd
 RETVAL=$?
 echo
 [ $RETVAL = 0 ] && rm -f /var/lock/subsys/httpd /var/run/httpd.pid
}
reload() {
 echo -n $"Reloading $prog: "
 check13 || exit 1
 killproc $httpd -HUP
 RETVAL=$?
 echo
}

# See how we were called.
case "$1" in
  start)
 start
 ;;
  stop)
 stop
 ;;
  status)
        status $httpd
 RETVAL=$?
 ;;
  restart)
 stop
 start
 ;;
  condrestart)
 if [ -f /var/run/httpd.pid ] ; then
  stop
  start
 fi
 ;;
  reload)
        reload
 ;;
  graceful|help|configtest|fullstatus)
 $Apachectl $@
 RETVAL=$?
 ;;
  *)
 echo $"Usage: $prog {start | stop | restart | condrestart | reload | status | fullstatus | graceful | help | configtest}"
 exit 1
esac

exit $RETVAL

Then issue the following command:

chkconfig httpd --level 345 on

This will set Apache to start on Linux level 3 4 and 5 automatically –  (by default, Red Hat is running on level 5 with X windows, most production machines will choose level 3, without GUI).

Reboot the machine; you can test it in the browser, now Apache web server starts up automatically with the machine reboot.
