PS3 Media Server as a Linux Service

[timpootle]

I am trying a slightly different hack. The runlevel was a red herring, but it is beyond my capability to prevent PMS from running until after network connection. The problem is compounded by Network-Manager requiring me to log in to Gnome before starting up.

My current thinking is a PHP file on my webserver (same machine as mediaserver) which will restart PMS when I click on it from the PS3 browser. Something like this:

Code: Select all

tim@bigbluelinux:/var/www$ cat pmsrestart.php
<?php
echo "hello";
echo exec ("/etc/init.d/pms-linux restart");
?>


Now I'm having problems with permissions. Normally I run "sudo /etc/init.d/pms-linux restart" but obviously I don't want to give the webserver sudo rights, so I have tried to CHOWN and CHGROUP the PMS files to the webuser, www-data. So far I have changed /var/run/pmslinux.pid but I still get

Code: Select all

/etc/init.d/pms-linux: line 93: kill: (2258) - Operation not permitted
rm: cannot remove `/var/run/pms-linux.pid': Permission denied
Warning: pms-linux is already running !


This is a lot of work for a dirty hack which shouldn't even be necessary.

Lostar - what did you mean by "he-he... speedup boot" ? I can only see your code slowing down boot time, not speeding it up. Please excuse my ignorance. I wasn't sure where to put your code, so I haven't tried it at all. My startup script doesn't have a block "case '$1' in start)" , only "case '$1' in start|stop|force-stop)" . Is this where your code should go, or in a separate block of its own?

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

NOTE: You'll need to sort out the user:group stuff and the PMS_ROOT path to the pms root dir

this script will also work on ubuntu (11.04) with PMS.conf if you change the following

Code: Select all

do_start()
{
   # Return
   #   0 if daemon has been started
   #   1 if daemon was already running
   #   2 if daemon could not be started
   start-stop-daemon --background --start --quiet --chuid $PMSUSER:$PMSGROUP --pidfile $PIDFILE --make-pidfile --exec $DAEMON --test > /dev/null \
      || return 1
   start-stop-daemon --background --start --quiet --chuid $PMSUSER:$PMSGROUP --pidfile $PIDFILE --make-pidfile --exec $DAEMON -- \
      $DAEMON_ARGS > /dev/null \
      || return 2
   # Add code here, if necessary, that waits for the process to be ready
   # to handle requests from services started subsequently which depend
   # on this one.  As a last resort, sleep for some time.
}


To

Code: Select all

do_start()
{
   # Return
   #   0 if daemon has been started
   #   1 if daemon was already running
   #   2 if daemon could not be started
   start-stop-daemon --background --start --quiet --chdir $PMS_ROOT --chuid $PMSUSER:$PMSGROUP --pidfile $PIDFILE --make-pidfile --exec $DAEMON --test > /dev/null \
      || return 1
   start-stop-daemon --background --start --quiet --chdir $PMS_ROOT --chuid $PMSUSER:$PMSGROUP --pidfile $PIDFILE --make-pidfile --exec $DAEMON -- \
      $DAEMON_ARGS > /dev/null \
      || return 2
   # Add code here, if necessary, that waits for the process to be ready
   # to handle requests from services started subsequently which depend
   # on this one.  As a last resort, sleep for some time.
}


by adding --chdir $PMS_ROOT you ensure that it loads your config file otherwise it will start at / instead of your folder for example /media/video orso.

hope it helps someone

Here's my configuration for setting up the PMS (1.23) on Fedora 15 as a background service running as unprivileged user 'pms' -- I've tried to leave the downloaded code as unchanged as possible...

You need to yum localinstall libzen0 and libmediainfo0 from http://mediainfo.sourceforge.net/en/Download/Fedora (atm, only F14 versions are available, but they work).

Also, yum install mencoder, java-1.6.0-openjdk and jna (jna is needed if you have /var mounted noexec, more on this later)

Download pms-generic-linux-unix-1.23.0.tgz (current version) and pms-config.tgz (attached to this post) to /var/tmp

Save pms-setup.tgz (attached), extract it, and then run the file (./pms-setup.sh)

The pms-setup.sh script will:
* create the pms user and group (home /opt/ps3mediaserver)
* extract /var/tmp/pms-config.tgz, creating directories /etc/opt/ps3mediaserver and /var/opt/ps3mediaserver, and the startup script in /etc/systemd/system
* extract /var/tmp/pms-generic-linux-unix-1.23.0.tgz in /opt
* create the link /opt/ps3mediaserver to the install in /opt
* fix logging configuration, and create a few links for DLNA cache and convenience
* install/enable the start script

You can then edit /etc/opt/ps3mediaserver/conf/PMS.conf (use the supplied default.conf file as a reference), and then start the service using:

Code: Select all

systemctl start ps3mediaserver.service

(or reboot, since the service is now enabled)

Result: All configuration is under /etc, all logs/databases are under /var, all code is under /opt.

NOTE #1: By default, PMS attempts to load the logging configuration file logback.headless.xml in the working directory (/opt/ps3mediaserver) - since the logging config distributed with PMS is not ideal for a headless setup, the setup script (above), moves it aside, and uses a supplied one: /etc/opt/ps3mediaserver/logback.headless.xml. Edit that file if you wish to alter logging.

NOTE #2: java's native library loader will attempt extract/link a copy of libjnidispatch.so in the 'java.io.tmpdir' directory to use in loading native libraries (like libmediainfo). Since /var is commonly mounted noexec, you might need to install the jna package (which includes libjnidispatch.so); that combined with the LD_LIBRARY_PATH set in the attached pms-config.tgz will prevent java extracting/linking to /var (since it would fail if it's noexec).

If you install an update, you should only need to run the "After each install/upgrade" section of the pms-setup.sh script.

Hope you find it useful

Scott, thank you very much for the post on creating the PS3 media server for F15. Your install and setup was very strait forward and simple to follow.

I have it set up and running on my ps3 and changed the search folder to my /home folder. But I am unable to browse the folders within my /home location. I have added the user 'pms' to my group within /etc/group and made sure my home folder has read/execute access for groups. But I am still unable to browse the folders from the PS3.

Thank you in advance for any help.

I'm not much of an expert to be able to break down those init files, but one thing you could do if you started the program from command line - use nohup.
That way when you logged out of your ssh session, PS3 Media Server would still be running.

bash prompt> nohup <path to PMS.sh>/PMS.sh
I know that this isn't the perfect solution - but you're going to need someone better versed in the scripts to help you.

If you're struggling with starting pms as a daemon, have a look at this article which breaks down some different options for running pms as a daemon:
