PS3 Media Server as a Linux Service

[martin]

So here is my startup-script for SuSE. It worked for me. But on manual startup it say failure - but it runs. Maybe a Linux-Guru is here and he/she knows to fix this . I've used another script and do some changes. Btw. does anybody know what with the (c) in the header is, must it still there - then I'll put it in here...

It's importend to run this script as root. Go to the terminal and get root-rights - su. Copy the script to /etc/init.d/. I've named it pmsd. Then do chown root /etc/init.d/pmsd. Then do chmod +rwx /etc/init.d/pmsd.. Then go to yast2 and open Systemservices (in my german SuSE, Systemdienste (Runlevel). Go to Expertview, then click on pmsd and then click on activate Service. That should be all, on next starup the service should run in the background...

Thanks for the script.

As the PS3 Media Server is a Java-app, you can force the Java process into running in the so-called "headless" state, which means it will not try to find the X-session. In other words, even if you have an X-session on the Linux server, it will run in console mode. Add the following Java option to the command-line in the PMS.sh-script: -Djava.awt.headless=true. The commandline would then become like (exec-line broken for readability):

Code: Select all

exec "$JAVA" $JAVA_OPTS -Xmx768M -Djava.encoding=UTF-8 -Djava.net.preferIPv4Stack=true \
   -Djava.awt.headless=true -jar "$PMS_JAR" "$@" &


I've also added to the script some variables to export the path of the script where I've put my PMS program. I also define a logfile that I pipe all output from the Java process to. Oh - and on my Ubuntu Hardy box the "log_daemon_msg" wasn't available in my default shell, so in my version of the script i source the relevant functions-file to get it.

My modified version of the script follows, in case it's usefull for somebody:

In order to make the logging work, the path you use in the PMS_LOG-variable needs to be created, and be writeable for the user running the Java-server, i.e. the user you put in the PMSUSER variable. I also make some tests in the PMS.sh-script (and also add the headless-option) in order to log to the logfile. The relevant changes from the default script follows (again, exec-line broken for readability):

Code: Select all

# Sanitycheck environment
[ "x$PMS_ROOT" = "x" ] && \
    echo "[ERROR] Environment variable 'PMS_ROOT' not set properly!" && exit 1
[ "x$PMS_LOG" = "x" ] && \
    echo "[ERROR] Environment variable 'PMS_LOG' not set properly!" && exit 1

# Execute the JVM
cd $PMS_ROOT
exec "$JAVA" $JAVA_OPTS -Xmx768M -Djava.encoding=UTF-8 -Djava.net.preferIPv4Stack=true \
  -Djava.awt.headless=true -jar "$PMS_JAR" "$@" 2>&1 >> "$PMS_LOG" &

Thanks to all the people who have put their time and effort into getting this software to work, also on a headless linux machine. This was exactly what I was looking for. But obviously, I'm posting here because I have a bit of a problem. I'm running Ubuntu Jaunty with a 2.6.28-11-server kernel (headless), and I try to get as much of the software through the apt repository, since that makes it easy to manage. The problem: I can run PMS.sh without a problem, and it seems that most of the codecs work (haven't tried everything yet, but avi, mkv, mp3 and jpg I have tested successfully so far, and if I have other codec problems, I will dig into it myself first), but I can't run the software through the init.d script that has been provided in this thread. That's to say, it will run, but apparently it doesn't find my PMS.conf file, which it does find when running the software directly from the command line.

I've basically used most of kes' setup, only modifying the things that are different for my setup. I really can't find what's wrong.

A few notes:

- My JAVA_HOME environment variable is set and correct.
- PMS.sh is executable for the user in the init script (kryz).
- PMS.conf is in the /usr/src/pms-linux-1.10.5 directory.
- I don't get any specific errormessages when running the init script, other than a very clear hint that ; this is what the log file (in var/log/pms) says:

It's clear here that the 'cd' command simply hasn't worked, so we're not in the PMS_ROOT directory. Another hint that this did not work is the following:

Code: Select all

kryz@orcrist:~$ /etc/init.d/PS3MediaServerd start
/etc/init.d/PS3MediaServerd: 13: source: not found
/etc/init.d/PS3MediaServerd: 94: log_daemon_msg: not found
/etc/init.d/PS3MediaServerd: 94: log_end_msg: not found

For some reason, the source command used in the script cannot be executed. And the other two errors, I don't know, my scripting / linux knowledge is far too basic.

Anyone able to help me out?

Small edit, as stipulated by the smart people of tweakers.net: source is a /bin/bash internal executable, and doesn't work under /bin/sh (unless /bin/sh is merely a symlink to /bin/bash), so I just changed the shebang to #!/bin/bash, and now I don't get the source / log_daemon_msg / log_end_msg errors anymore. But the core issue is not solved yet.

Edit 2: I've found the cause for the issue. For some reason, when in the init script, the current dir is indeed de PMS directory, but when in PMS.sh, pwd is /. I thought the 'if' statement in the PMS.sh would do something with that, but only now I get that it doesn't, so I just added a 'cd "$PMS_HOME"' line in the script, and everything seems to work. If anyone would like to see my new and improved versions of the scripts, don't hesitate to ask. I won't put them in this post now, since it's already full with the problem scripts.

[russdot]

This thread is exactly what I was looking for! Thanks so much to all the people who contributed.

I'm going to note the change I made to kes's script (not necessary by any means, but might help)... I changed the signal that gets sent to the daemon. So instead of sending a SIGSTOP (signal #2) which merely 'pauses' the execution of the PS3 media server, I changed it to SIGTERM (signal #15) to actually shut down the PS3 media server (and your PS3 will reflect that by removing the icon for the media server and notifying you that the connection was lost)

So, the line:

Code: Select all

start-stop-daemon --stop --signal 2 --retry 5 --quiet --name java

Was changed to:

Code: Select all

start-stop-daemon --stop --signal 15 --retry 5 --quiet --name java

then using init.d: (I called mine 'ps3ms')

Code: Select all

sudo /etc/init.d/ps3ms start

starts the server and

Code: Select all

sudo /etc/init.d/ps3ms stop

stops the server.

Good luck!

[edwardecl]

Service script works very nice but I have one... slight issue.

The stop script ends up closing all Java apps how do you make it so it only stops PMS?

I have Azureus running as a service and when you stop PMS is quits both apps.

[WorldOfHurt]

If you want to use start-stop-daemon with the "--pidfile $PIDFILE" option on Debian, also usethe "--make-pidfile" option because PMS.sh does not do it. And remember not to use the "-name $NAME" option, as the process does not run with the expected name - just use the pidfile.

Also DO NOT put the trailing ampersand on the last PMS.sh line.

Otherwise the pidfile will either not be created (no make-pidfile), or will contain the pid of the PMS.sh script not the java process (trailing ampersand).

Also, if you want to force headless without modifying the PMS.sh script, add this to your init.d script:

Code: Select all

JAVA_OPTS="-Djava.awt.headless=true"
export JAVA_OPTS


I started from the /etc/init.d/skeleton and wrote an init script that combines the best of the script above with the regular start-stop-daemon binary. If anyone wants it, I'll post it - just let me know.

[Loops]

Hy

I have write a start/stop script , it not use the pms.sh script.


Watch the viewtopic.php?f=3&t=4487 page. If you have an other jave applet, the stop not kill this one.

Regards/Cordialement.

[lordemsworth]

Worldofhurt,

Is your script a Debian script?

Amir

[WorldOfHurt]

Worldofhurt,

Is your script a Debian script?

Amir

Yes. Well, it's a linux shell script, so it works on my Debian etch server

I'll post it later if its any use to you.

[lordemsworth]

if you would be so kind, it would be appreciated.
