startup / shutdown script (rc.d)

[gmoniey]

Hi,

so i tried the script you mentioned, and it doesnt seem as if it is being
called on startup. Here is my script (rails.sh):

#!/bin/sh
case "$1" in
start)
        kldload accf_http
        mongrel_rails cluster::start -C
/usr/local/www/app/config/mongrel_cluster.yml
        /usr/local/www/app/script/backgroundrb start
        ;;
stop)
        mongrel_rails cluster::stop -C
/usr/local/www/app/config/mongrel_cluster.yml
        /usr/local/www/app/script/backgroundrb stop
        ;;
*)
        echo "Usage: `basename $0` {start|stop}" >&2
        exit 64
        ;;
esac


Also, I double checked that the permissions were correct (I made it the same
as the other scripts in the rc.d directory). Here is the directory listing:

-r-xr-xr-x  1 root  wheel   179 Jun  3 17:26 000.apache2libs.sh
-rwxr-x---  1 root  wheel   181 May  2 02:19 000.mysql-client.sh
-r-xr-xr-x  1 root  wheel  3524 Jun  3 12:07 apache2.sh
-r-xr-xr-x  1 root  wheel  1689 May  2 02:30 mysql-server.sh
-r-xr-xr-x  1 root  wheel   651 Jan 15 19:31 proftpd.sh
-r-xr-xr-x  1 root  wheel   445 Jun  3 17:26 rails.sh


While looking through the other files in the rc.d directory, I noticed that
000.apache2libs.sh has the similar structure as the file you suggested, so I
attempted to put my commands in there, but it seems as if they are not being
called either (i.e. after reboot, when i do a ps aux, i dont see the
commands i expect to be started)...

I also tried adding rails_enable = "YES" in the rc.conf file, and that
didn't work (although I didn't expect it to work, as I didn't assign a name
in my script).

any ideas?
