Howto: Install SqueezeCenter 7.2 on D-Link DNS-323

How to install SqueezeCenter 7.2 on D-Link DNS-323

I've documented the steps I used to install SqueezeCenter 7.2 on a DNS-323. By looking for how to do it, I only found explanation explaining how to install an older version by chrooting to a debian or statements saying that it could never run on a DNS-323, so I decided to try it by myself.
And finally it turned out to be possible and quite usable (the web front-end is a bit slow, but I don't care because I don't use it quite often).
There may be a shorter way, but these steps worked for me twice (I retried from scratch in order to write this tutorial).

I've tried to describe all commands, so that even a UNIX newbie can copy and paste all commands in a telnet session and get it work.
When you see a line like this:
"/mnt/HD_a2/ffp # rsync -av inreto.de::dns323/fun-plug/0.5/packages ."
It shows you the current path where you should normally be when entering the command (/mnt/HD_a2/ffp #) and the command to type (rsync -av inreto.de::dns323/fun-plug/0.5/packages .) => type/copy the command from the #.

---------------------------------------------------

Starting point: DNS-323, Firmware Version 1.05

###########################################
1) Prepare the DNS-323 and install ffp 0.5:
###########################################
1.1) Log in the administration UI of the DNS-323, go to the tab Advanced/Users and add a new user 'squeezecenter'

1.2) Download and install the Fonz Fun-Plug 0.5 as described under http://www.inreto.de/dns323/fun-plug/0.5/ to get telnet access to the DNS-323. (Copy fun_plug and fun_plug.tgz to Volume 1 and reboot)

1.3) Install all the additional ffp0.5 packages. (You certainly don't need all of them, but disk space is the only thing I have enough on my DNS-323 and I didn't want to search long for what is necessary or not. Not that after the SqueezeCenter is installed you can still remove unused packages if you need more disk space)

telnet ip_of_your_dns323
/ # cd ffp
/mnt/HD_a2/ffp # rsync -av inreto.de::dns323/fun-plug/0.5/packages .
/mnt/HD_a2/ffp # cd packages
/mnt/HD_a2/ffp/packages # funpkg -i *.tgz

At this point, you have telnet access on your DNS-323 and the most important unix programs and services (compiler, perl, mysql, etc...) are installed on it

#############################
2) Configure and start mysql:
#############################
Mysql is the database used by SqueezeCenter to store all the metadata of your music collection. By default SqueezeCenter starts its own instance of mysql and ignores any existing mysql installation. In the case of the DNS-323 we want Squeezecenter to use the mysql instance which is installed on the system (installed in the previous step), because memory is short and SqueezeCenter doesn't provide a mysql binary for ARM.

2.1) Create a configuration file for mysql:
The ffp installation of mysql comes without working configuration file. We have to copy it from the examples directory and modify it to indicate a path for the database which exists in the DNS323:

/mnt/HD_a2/ffp/packages # cd /ffp/etc
/mnt/HD_a2/ffp/etc # cp examples/mysql/my-small.cnf my.cnf

Edit the new created configuration file my.cnf (use either vi to edit the file from within the telnet session, or if you don't know how to use vi, give write access to all user to the file 'chmod 666 my.cnf', open the file in a text editor from your computer, and restore the write access after the modification with 'chmod 644 my.cnf')
- search for the section [mysqld] and add the line 'datadir = /ffp/var/mysql' after the line 'thread_stack = 64K'. You should have something like that:

# The MySQL server
[mysqld]
port		= 3306
socket		= /ffp/var/run/mysql/mysql.sock
skip-locking
key_buffer = 16K
max_allowed_packet = 1M
table_cache = 4
sort_buffer_size = 64K
read_buffer_size = 256K
read_rnd_buffer_size = 256K
net_buffer_length = 2K
thread_stack = 64K
datadir = /ffp/var/mysql

2.2) Install the mysql database

/mnt/HD_a2/ffp/etc # mysql_install_db

2.3) Make mysql start automatically at boot time

/mnt/HD_a2/ffp/etc # cd /ffp/start/
/mnt/HD_a2/ffp/start # chmod a+x mysqld.sh

2.4) Starts manually mysql

/mnt/HD_a2/ffp/start # sh mysqld.sh start

2.5) Secure mysql

/mnt/HD_a2/ffp/start # mysql_secure_installation

Answer to the questions as follow:

- Set root password? [Y/n] Y
- New password: yourpassword
- Remove anonymous users? [Y/n] Y
- Disallow root login remotely? [Y/n] Y
- Remove test database and access to it? [Y/n] Y
- Reload privilege tables now? [Y/n] Y

2.6) Create the squeezecenter database

/mnt/HD_a2/ffp/start # mysql -u root -p
Enter password: your_root_password

mysql> create database squeezecenter;
mysql> grant all on squeezecenter.* to squeezecenter identified by 'your_password';
mysql> flush privileges;
mysql> quit

At that point you have a running MySQL installation and an empty squeezecenter database that SqueezeCenter can use. MySQL will start automatically when your reboot the DNS-323

#########################################
3) Download and install SqueezeCenter 7.2
#########################################

3.1) Download and unzip SqueezeCenter 7.2:

/mnt/HD_a2/ffp/start # cd /mnt/HD_a2/
/mnt/HD_a2 # wget http://downloads.slimdevices.com/SqueezeCenter_v7.2.0/squeezecenter-7.2-noCPAN.tgz
/mnt/HD_a2 # tar xvfz squeezecenter-7.2-noCPAN.tgz 
/mnt/HD_a2 # cd squeezecenter-7.2-noCPAN/

3.2) Modify the header of the .pl files so that it uses /ffp/bin/perl instead of /bin/perl
- Edit slimserver.pl and scanner.pl and modify the first line to be:

#!/ffp/bin/perl -w

[yannick]

#################################
4) Install dependent perl modules
#################################

4.1) Download and install some dependent perl modules in the SqueezeCenter installation:

/mnt/HD_a2/squeezecenter-7.2-noCPAN # perl Bin/build-perl-modules.pl XML::Parser::Expat HTML::Parser JSON::XS Digest::SHA1 YAML::Syck

Answer all questions as follow:

- Please enter a perl binary to use (defaults to /usr/bin/perl)
This must be the same perl binary that you ran this program with --> /ffp/bin/perl
- Please enter the path to your SqueezeCenter directory (ex: /usr/local/slimserver) --> /mnt/HD_a2/squeezecenter-7.2-noCPAN
- Please enter a directory to download files to --> /ffp/tmp

The system will automatically download, compile and install a few perl modules. This will take some time and output a few warnings and non blocking errors that you can ignore.

4.2) Download and install manually additional dependent modules that are not installable with the build-perl-modules-pl script of SqueezeCenter. To do that we go to the temp directory /ffp/tmp:

/mnt/HD_a2/squeezecenter-7.2-noCPAN # cd /ffp/tmp/

4.2.1) Download and install GD

/mnt/HD_a2/ffp/tmp # wget http://search.cpan.org/CPAN/authors/id/L/LD/LDS/GD-2.35.tar.gz
/mnt/HD_a2/ffp/tmp # tar xfz GD-2.35.tar.gz
/mnt/HD_a2/ffp/tmp # cd GD-2.35/
/mnt/HD_a2/ffp/tmp/GD-2.35 # perl Makefile.PL
/mnt/HD_a2/ffp/tmp/GD-2.35 # make
/mnt/HD_a2/ffp/tmp/GD-2.35 # make install
/mnt/HD_a2/ffp/tmp/GD-2.35 # cd ..

4.2.2) Download and install DBI

/mnt/HD_a2/ffp/tmp # wget http://search.cpan.org/CPAN/authors/id/T/TI/TIMB/DBI-1.607.tar.gz
/mnt/HD_a2/ffp/tmp # tar xfz DBI-1.607.tar.gz
/mnt/HD_a2/ffp/tmp # cd DBI-1.607/
/mnt/HD_a2/ffp/tmp/DBI-1.607 # perl Makefile.PL
/mnt/HD_a2/ffp/tmp/DBI-1.607 # make
/mnt/HD_a2/ffp/tmp/DBI-1.607 # make install
/mnt/HD_a2/ffp/tmp/DBI-1.607 # cd ..

4.2.3) Download and install DBD::mysql

/mnt/HD_a2/ffp/tmp # wget http://search.cpan.org/CPAN/authors/id/C/CA/CAPTTOFU/DBD-mysql-4.008.tar.gz
/mnt/HD_a2/ffp/tmp # tar xfz DBD-mysql-4.008.tar.gz
/mnt/HD_a2/ffp/tmp # cd DBD-mysql-4.008/
/mnt/HD_a2/ffp/tmp/DBD-mysql-4.008 # perl Makefile.PL
/mnt/HD_a2/ffp/tmp/DBD-mysql-4.008 # make
/mnt/HD_a2/ffp/tmp/DBD-mysql-4.008 # make install
/mnt/HD_a2/ffp/tmp/DBD-mysql-4.008 # cd ..

Note that if you are trying to compile this module on another NAS as the DNS-323 with the same architecture (for instance Zyxel NSA-220) you may have to use the following options:

perl Makefile.PL --libs="-Wl,-rpath -Wl,/ffp/lib -rdynamic -L/ffp/lib/mysql -lmysqlclient -lz -lcrypt -lnsl -lm -L/ffp/lib -lssl -lcrypto"

(see post #26 in this thread)

4.2.4) Download and install Encode:etect

/mnt/HD_a2/ffp/tmp # wget http://search.cpan.org/CPAN/authors/id/J/JG/JGMYERS/Encode-Detect-1.01.tar.gz
/mnt/HD_a2/ffp/tmp # tar xfz Encode-Detect-1.01.tar.gz

/mnt/HD_a2/ffp/tmp # tar xfz Template-Toolkit-2.20.tar.gz
/mnt/HD_a2/ffp/tmp # cd Template-Toolkit-2.20/
/mnt/HD_a2/ffp/tmp/Template-Toolkit-2.20 # perl Makefile.PL

> answer all questions with y

/mnt/HD_a2/ffp/tmp/Template-Toolkit-2.20 # make
/mnt/HD_a2/ffp/tmp/Template-Toolkit-2.20 # make install
/mnt/HD_a2/ffp/tmp/Template-Toolkit-2.20 # cd ..

4.2.6) Download and install Compress::Raw::Zlib

/mnt/HD_a2/ffp/tmp # wget http://search.cpan.org/CPAN/authors/id/P/PM/PMQS/Compress-Raw-Zlib-2.015.tar.gz
/mnt/HD_a2/ffp/tmp # tar xfz Compress-Raw-Zlib-2.015.tar.gz
/mnt/HD_a2/ffp/tmp # cd Compress-Raw-Zlib-2.015/
/mnt/HD_a2/ffp/tmp/Compress-Raw-Zlib-2.015 # perl Makefile.PL

/mnt/HD_a2/ffp/tmp/Compress-Raw-Zlib-2.015 # make install
/mnt/HD_a2/ffp/tmp/Compress-Raw-Zlib-2.015 # cd ..

4.2.7) Download and install IO::Compress::Base

/mnt/HD_a2/ffp/tmp # wget http://search.cpan.org/CPAN/authors/id/P/PM/PMQS/IO-Compress-Base-2.015.tar.gz
/mnt/HD_a2/ffp/tmp # tar xfz IO-Compress-Base-2.015.tar.gz
/mnt/HD_a2/ffp/tmp # cd IO-Compress-Base-2.015/
/mnt/HD_a2/ffp/tmp/IO-Compress-Base-2.015 # perl Makefile.PL

4.2.8) Download and install IO::Compress::ZLib

/mnt/HD_a2/ffp/tmp # wget http://search.cpan.org/CPAN/authors/id/P/PM/PMQS/IO-Compress-Zlib-2.015.tar.gz
/mnt/HD_a2/ffp/tmp # tar xfz IO-Compress-Zlib-2.015.tar.gz
/mnt/HD_a2/ffp/tmp # cd IO-Compress-Zlib-2.015/
/mnt/HD_a2/ffp/tmp/IO-Compress-Zlib-2.015 # perl Makefile.PL
/mnt/HD_a2/ffp/tmp/IO-Compress-Zlib-2.015 # make
/mnt/HD_a2/ffp/tmp/IO-Compress-Zlib-2.015 # make install
/mnt/HD_a2/ffp/tmp/IO-Compress-Zlib-2.015 # cd ..

4.2.9) Download and install Compress::ZLib

wget http://search.cpan.org/CPAN/authors/id/P/PM/PMQS/Compress-Zlib-2.015.tar.gz
/mnt/HD_a2/ffp/tmp # tar xfz Compress-Zlib-2.015.tar.gz
/mnt/HD_a2/ffp/tmp # cd Compress-Zlib-2.015/
/mnt/HD_a2/ffp/tmp/Compress-Zlib-2.015 # perl Makefile.PL
/mnt/HD_a2/ffp/tmp/Compress-Zlib-2.015 # make
/mnt/HD_a2/ffp/tmp/Compress-Zlib-2.015 # make install
/mnt/HD_a2/ffp/tmp/Compress-Zlib-2.015 # cd ..

4.3) Remove conflicting CPAN libraries from the SqueezeCenter installation
SqueezeCenter brings some CPAN libraries which conflicts with the one we just installed. We need to delete them:

/mnt/HD_a2/ffp/tmp # cd /mnt/HD_a2/squeezecenter-7.2-noCPAN/CPAN/
/mnt/HD_a2/squeezecenter-7.2-noCPAN/CPAN # rm -r Encode/
/mnt/HD_a2/squeezecenter-7.2-noCPAN/CPAN # rm -r Template*
/mnt/HD_a2/squeezecenter-7.2-noCPAN/CPAN # rm -r Compress/

4.4) Set the environment variable LD_LIBRARY_PATH to /ffp/lib/mysql so that DBD::mysql works:

/mnt/HD_a2/squeezecenter-7.2-noCPAN/CPAN # export LD_LIBRARY_PATH=/ffp/lib/mysql

4.4.1) Set the environment variable LD_LIBRARY_PATH at boot time:
Edit the file /ffp/etc/rc and replace the line "unset LD_LIBRARY_PATH" with "EXPORT LD_LIBRARY_PATH=/ffp/lib/mysql"

At that point you have all perl modules necessary to run SqueezeCenter

################################################## #############
5) First starts of SqueezeCenter and final settings adjustments
################################################## #############

5.1) First start SqueezeCenter

/mnt/HD_a2/squeezecenter-7.2-noCPAN # ./slimserver.pl --user=squeezecenter

It will prompt a bunch of error messages and exit.
During this first startup, several log and cache files have been generated.
Unfortunately those files are created by default with root ownership and the user 'squeezecenter' doesn't have access on it. We have to fix that:

5.2) Fix ownership of generated files

/mnt/HD_a2/squeezecenter-7.2-noCPAN # chown -R squeezecenter:500 Cache/ Logs/ prefs/

5.3) Second start of SqueezeCenter:

/mnt/HD_a2/squeezecenter-7.2-noCPAN # ./slimserver.pl --user=squeezecenter

Even this 2nd start with fail. This time the configuration file for the server has been generated. We need to change its ownership as well and modify it, so that it uses the mysql instance installed on the system previously

5.4) Fix ownership of generated files (again)

/mnt/HD_a2/squeezecenter-7.2-noCPAN # chown -R squeezecenter:500 Cache/ Logs/ prefs/

5.5) Edit prefs/server.prefs
- Search for the lines defining dbpassword, dbsource and dbusername and modify them as follow:

dbpassword: 'your_password'
dbsource: dbi:mysql:hostname=localhost;port=3306;database=squeezecenter
dbusername: root

Make sure that hostname is localhost and NOT 127.0.0.1. The port must be the same as the port used by mysql as defined in /ffp/etc/my.cnf (3306 by default). The database must be the same name as the database created in step 2.6

#############################
6) Start SqueezeCenter daemon
#############################

/mnt/HD_a2/squeezecenter-7.2-noCPAN # ./slimserver.pl --user=squeezecenter --daemon

The server should now startup as a daemon. You can control with 'top' the CPU and memory usage. Once the CPU usage is back to zero, the server is up and you can access it with your web browser on the port 9000.
Configure from there the server.

Note that a message like

Useless use of a constant in void context at /i-data/1776811d/squeezecenter-7.2-noCPAN/Slim/Networking/Slimproto.pm line 129.

is normal and not critical. It is also normal that the scripts returns after this error. In case the server doesn't start (process not visible in top or ps), check in Logs/server.log for error messages, or start without the --daemon option, to see the error messages on the screen.

##########################################
7) Make SqueezeCenter start automatically

Yannick

Thanks for the instructions, i'll try it out. By the way how do you copy and paste in putty?

[raven22]

How do i find out which packages in ffp are needed? I run my ffp from usb stick (to allow the disks to spindown) so diskspace is not unlimited.

[yannick]

I'm using Linux, so to copy paste, I only have to highlight the text to copy, and press the middle mouse button at the location where I want to paste it. I don't know how it works with Windows.

As for the packages which are needed, if you really need to save space, you'll have to start with a minimum number of packages and see where it complains that something is missing.
The minimum you need for sure is gzip, perl, mysql, gcc and make. You probably need zlib, libxml, libpng, libjpeg and id3lib as well. For the rest you'll have to try...

[badbob]

thanks. This thread should be made a sticky. Looks quite complicated setup, and bit long to do. Think I'll sell off the DNS-323 the fan makes it a right noisy bugger.

[Superkikim]

Hi,

Thank you for your great tutorial. Very easy to follow, crystal clear.

I'm trying this on a Zyxel NSA-220 (similar hardware). Everything goes find, until the installation of DBD-mysql-4.008. The Makefile.pl script runs ok. Then on make, I get the following output. Any idea ?

[yannick]

One thing which is suspect there is that it tries to mix libraries from /ffp/lib and from the firmware (/usr/lib), which is I think the reason of your problem.
Look at this thread on this forum http://forum.dsmg600.info/t2906-Walk...im-center.html where somebody has a similar problem on a CH3SNAS and fonz suggested a few steps how to solve it. Unfortunately I'm not really an expert on C compilers and I am happy that things went well on the DNS323, but the solution is probably in one of those environment libraries, such as LD_RUN_PATH.
You can also look there http://dev.mysql.com/doc/refman/5.1/...-problems.html if maybe you find a hint on how to compile this perl extension...

Do all other perl modules compile fine (you can do 4.2.4->4.4.1 even if 4.2.3 failed)?

Yannick

[remd]

Yannick,

I followed your instructions, and everything works exactly as you described until the last step when I start squeezecenter as a daemon I get this error and it stops:
"Useless use of a constant in void context at /mnt/HD_a2/squeezecenter-7.2-noCPAN/Slim/Networking/Slimproto.pm line 129 "

The other difference I also had was that I had to adduser squeezecenter when I launched slimserver.pl the first time, because I had no squeezcenter user.
