 Posted: Mon Dec 04, 2006 4:49 am Post subject: [SOLVED] Init Script for Non-Root Service |
 |
|
I'm setting up a DC++ hub with Verlihub. I have it set up and working fine, as both root and the user hub. I have the following init script, which starts the hub find as the root user:
| Code: |
#!/sbin/runscript
# Verlihub boot script for gentoo distributions
# feel free to change these
confdir=/etc/verlihub
logdir=/var/log/verlihub
verlihubexe=/usr/local/bin/verlihub
# don't change these ones, though!
loghistorydir=$logdir/history
logfile=$logdir/log
errfile=$logdir/err
loghistfile=$loghistorydir/log
errhistfile=$loghistorydir/err
pidfile=/var/run/verlihub.pid
requiredfiles="dbconfig db"
optionalfiles="motd faq rules help_admin help_master help_op help_usr help_reg"
depend() {
need net
need mysql
}
start() {
ebegin "Starting verlihub"
# make sure the configuration directory exists
if [ ! -d $confdir ]; then
eerror FATAL ERROR: missing configuration directory $confdir
return 1
fi;
# ensure log directory exists
if [ ! -d $logdir ]; then
mkdir $logdir
fi;
# ensure log history directory exists
if [ ! -d $loghistorydir ]; then
mkdir $loghistorydir
fi;
# check for the required files
for f in $requiredfiles; do
file=$confdir/$f
if [ ! -e $file ]; then
eerror "FATAL ERROR: missing required file $file"
return 1
fi;
done;
# check for the optional files
for f in $optionalfiles; do
file=$confdir/$f
if [ ! -e $file ]; then
eerror "WARNING: missing file $file, some functionality will be disabled"
fi;
done;
# backup logs and date/timestamp them
if [ -e $errfile ]; then
mv -f $errfile $errhistfile.`date +%Y_%m_%d_%k:%M:%S`.old
fi
if [ -e $logfile ]; then
mv -f $logfile $loghistfile.`date +%Y_%m_%d_%k:%M:%S`.old
fi
# start the hub
$verlihubexe >$logfile 2>$errfile &
pid=$!
disown $pid
echo $pid > $pidfile
eend $?
}
stop() {
ebegin "Stopping verlihub"
pid=`cat $pidfile`
kill $pid
rm $pidfile
eend $?
}
restart() {
svc_stop
sleep 5
svc_start
}

My question is, how can I modify it to make the hub start as the user hub? As far as I know, there's no way to configure the hub to change to a non-root user, like I think Apache can. So, it has to be something within the init script. Could I just add su - hub just before $verlihubexe >$logfile 2>$errfile &?
Thanks for any insight.
Edit: Typo.

Try replacing the line were you actually start the app ($verlihubexe >$logfile 2>$errfile &) with the following;
| Code: | | start-stop-daemon --start -c USERNAME -x $verlihubexe >$logfile 2>$errfile & |
replacing USERNAME with the name of the user you want the program to run as.
You can also use start-stop-daemon to manage the pid file, set the nice priority or even operate within a chroot, if desired.
I highly recommend reading the start-stop-daemon man page.
Also, on a side note, all the variables you set at the start should really go into a conf file under the same name as the init script but located in /etc/conf.d, the variables will be available to the init script.

Thank you! That starts the hub without an error, but when I do run /etc/init.d/verlihub start I get the following:
| Code: |
* Re-caching dependency info (mtimes differ)...
* Re-caching dependency info (mtimes differ)...
* Re-caching dependency info (mtimes differ)...
* Re-caching dependency info (mtimes differ)...
* Starting verlihub ...
mv: when moving multiple files, last argument must be a directory
Try `mv --help' for more information.

I'm thinking that's just a permissions issue though... I think I can call this solved. |

Your date command returns a space.
So your mv command has three files, so when copying multiple files move expects the last to be a directory. (Of course it is a file and errors)
Try | Code: | | date +%Y_%m_%d_%k:%M:%S |
in a terminal and you can see the space. %k returns a space on single digit hours instead of 01, 02, etc. Use %H instead. | Code: | | date +%Y_%m_%d_%H:%M:%S |
