Title: Boinc / setiathome
Post by: rmoria on November 25, 2004, 09:47:48 PM

I have made an effort to get this working.
It seems to be working well, though I do have trouble sometimes with the lockfile.
Any sugestions are welcome. I am pretty new at this.

Adapted from http://noether.vassar.edu/~myers/help/boinc/unix.html

Install libgcc-3.0.4-1.i386.rpm, otherwise boinc won't work.

Code: [Select]

rpm -Uhv libgcc-3.0.4-1.i386.rpm

Create user boinc
   

Code: [Select]

adduser boinc

Get the latest Linux/x86 client from http://boinc.berkeley.edu/download.php
 and place it in /home/boinc/ (when I wrote this the version was 4.13).
Get the boinc script (or make it yourself), name it boincrun, place it in /home/boinc

Hi rmoria,

Nice! Looks good ... but I am still on seti :-D

Havent had more than a cursory look but here are some comments:

You are (somewhat) going against SME standards like
/home/e-smith/files/users  
is the SME user directory however I cannot see where the setup should fail with your RH adduser style...

chmod +x   seems a bit "too much" it's only boinc isn't it?

Now why not start boincrun as user boinc instead of as admin or root?

- Check the settings of the lockfile once...
- Give us the error.log you have if the error persists.

Regards
Reinhold

P.S.: Since I haven't looked for ages...
Is it easy to convert? Can I keep my "standings" ß

User root or admin didn't seem to do the job.
I tried a existing user, but they were not allowed to log on (su command).

In the original script there was a pipe to a error log, but that didn't seem to work either. As I said, I am new at this.

Added the folowing code to the script, to get rid of the lockfile problems (look at the first 3 lines where to paste it). It's not pretty but it works.

Code: [Select]

case "$1" in
  start)
        cd $BOINCDIR

PID=pidof $BOINCEXE
if [ "$PID" != "" ]; then
 echo "BOINC is already running"
 exit 4
else
 rm $BOINCDIR/lockfile -f
fi
