Original idea taken from OpenACS document Chapter 6. Production Environments [1]

Requirements

Daemontools [2]


Configuration Steps:

1. Download and install Daemontools. Make sure svscanboot is started from inittab. Check if your inittab contains svscanboot. For example:

   SV:123456:respawn:/command/svscanboot


2. Create service directory for your AOLserver instance

   mkdir /service/YOUR-AOLserver or /var/service/YOUR-AOLserver

Once created you'll also see supervise directory under it.

3. Now create a script named arun under above directory.

   #!/bin/sh
   exec /usr/local/aolserver/bin/nsd -it /usr/local/aolserver/YOUR-AOLserver/etc/config.tcl -u USERNAME -g GROUPNAME

4. Make arun script executable:

   chmod +x arun

5. Execute arun script and confirm that it starts your server

   ./arun

6. If all is fine now rename the arun to run so that it gets picked up by Daemontools:

   mv arun run

7. check process list for your nsd YOUR-AOLserver process.

  ps -ef |grep nsd

Addon: Using init.d/YOUR-AOLserver script to stop/start/restart/status

   #!/bin/sh
   #
   # YOUR-AOLserver  This shell script takes care of starting and stopping
   #               YOUR-AOLserver
   #
   # chkconfig: 345 65 35
   # description: YOUR-AOLserver is a web server based on AOLserver
   
   # Source function library.
   . /etc/rc.status
   
   # Check Argument
   case "$1" in
     start)
       svc -u /service/YOUR-AOLserver
       ;;
     stop)
       svc -d /service/YOUR-AOLserver
       ;;
     status)
       svstat /service/YOUR-AOLserver
       ;;
     restart)
       "$0" stop
       sleep 1
       "$0" start
       ;;
     *)
       echo "Usage: YOUR-AOLserver {start|stop|restart|status}"
       exit 1
   esac
   exit 0

Now YOUR-AOLserver can be start, stop, restart, staus using:

   /etc/init.d/YOUR-AOLserver stop
   /etc/init.d/YOUR-AOLserver start
   /etc/init.d/YOUR-AOLserver restart
   /etc/init.d/YOUR-AOLserver status
