Hi guys,

I've come to a road block so i need some help.

1)I have an exe which i need to run at start up.

So I put the following bash file in the inid.d directory:


Shell Scripting Syntax (Toggle Plain Text) 
  1. #!/bin/bash
  2. #
  3. #
  4.  
  5. . /etc/rc.d/init.d/functions
  6.  
  7. EXE_DIR="/root/monkey-0.9.2/bin/"
  8. EXE_NAME="monkey"
  9.  
  10.  
  11. #############################################################
  12. #################### Functions ##############################
  13. #############################################################
  14.  
  15. function start {
  16.     RUNNING=`ps -ef | grep -c ./${EXE_NAME}\$`
  17.     if [ $RUNNING -ge 1 ]; then
  18.         echo "${EXE_NAME} is already running"
  19.         echo_failure
  20. 	echo ""
  21.     else
  22. 	if [ ! -x "${EXE_DIR}${EXE_NAME}" ]; then
  23. 		echo ""
  24. 		echo  "[error] ${EXE_NAME} doesn't exist"
  25. 		echo_failure
  26. 		echo ""
  27. 	else
  28.                 cd "${EXE_DIR}"                
  29.                 sleep 1
  30. 		./${EXE_NAME} > output &
  31. 	        disown
  32.                 echo  "Restarting ${EXE_NAME}"
  33. 		echo_ok
  34. 		echo ""
  35. 	fi
  36.     fi
  37. }
  38.  
  39. function stop {
  40.     echo ""
  41.     echo "Stopping ${EXE_NAME}"
  42.     RUNNING=`ps -ef | grep -c ./${EXE_NAME}\$`
  43.     if [ $RUNNING -ge 1 ]; then
  44. 	ID=`ps -ef | grep ${EXE_NAME} | grep -v grep | awk '{print $2}'`
  45. 	echo "PID= $ID"
  46. 	kill -9 $ID
  47. 	echo_ok
  48. 	echo ""
  49.     else
  50.         echo  "${EXE_NAME} is not running"
  51.         echo_failure
  52.         echo ""
  53.     fi
  54.  
  55.  
  56.     return 0;
  57. }
  58.  
  59. function restart {
  60. 	stop
  61. 	start
  62. 	return 1;
  63. }
  64.  
  65. function status {
  66.     RUNNING=`ps -ef | grep -c ./${EXE_NAME}\$`
  67.     if [ $RUNNING -ge 1 ]; then
  68. 	echo  "${EXE_NAME} Running"
  69.         echo_ok
  70.         echo ""

  101. 	*)
  102.  
  103. 	exit 1
  104. esac
  105.  
  106. exit 0

The funny thing is the pid says it is running on boot. But it only works when I log on and restart the program manually?!

Any ideas?

What do you mean "The funny thing is the pid says it is running on boot"? Scripts in init.d must be referenced from their run levels. Depending on your distro you should have a command for update-rc.d to specify the run levels to execute the scripts.

Also the symlink naming convention for executing a process in the rc?.d directories is important. For example if monkey logs to syslog but starts before syslog is running then you may have a problem. HTTPDs are typically one of the last processes to start.

[edit]
One more thing .. usually scripts use pidfiles in /var/run . There are a lot of situations where ps may not return what you expect. ie a user has a process start up with your exe's name which will cause your script to think it is already running, regardless of its current state.

Well the program (c++) is actually running on start up. You see it is mini light-weight webserver.

http://www.monkey-project.com/

However, when I go to the web page it comes up with the 404 page not found error. But when I restart the program manually from the terminal, it works fine.

>Depending on your distro you should have a command for update-rc.d to specify the run levels to execute the scripts.

At the moment I'm running it off a itx board that was compiled from scratch. I didn't do it so I'm kinda clueless. But if I can get this working in ubuntu for example it would be a start.

Thanx in advance.

Post the output for this sk:/etc# ls -al rc?.d/ Your directory structure appears to be a little different in /etc so you may need to find where the rc?.d's are located: sk:/etc# find ./ -iname rc\*\.d

Here is how to add a script in debian (more or less the same in ubuntu, which is debian based):

http://74.125.47.132/search?q=cache:...&ct=clnk&gl=us

[edit]
/etc/init.d/skeleton contains a template for adding new startup scripts. You should be able to modify it to your needs

eh that wasn't the command I posted. ls -al rc?.d/ the ? expands for rc0.d/ rc1.d/ to list the directory contents, such as:

Oh right not sure, I'm completely lost when it comes to shell scripting and linux

Shell Scripting Syntax (Toggle Plain Text) 
  1. root@localhost:/etc# find ./ -iname rc\*\.d
  2. ./rc.d
  3. ./rc.d/rc6.d
  4. ./rc.d/rc2.d
  5. ./rc.d/rc0.d
  6. ./rc.d/rcsysinit.d
  7. ./rc.d/rc1.d
  8. ./rc.d/rc5.d
  9. ./rc.d/rc3.d
  10. ./rc.d/rc4.d
  11. root@localhost:/etc#

Ok -- now try this:
ls -alR /etc/rc.d/rc?.d
It will be a lot of output so you have two options
1) Write it to a file: ls -alR /etc/rc.d/rc?.d >> /tmp/outfile
2) Use a pager: ls -alR /etc/rc.d/rc?.d | less or ls -alR /etc/rc.d/rc?.d | more . Your system may not have one of the pagers installer. In my opinion less > more, but either will work.
