Server setup for developers

Requirements

This server can be run on linux/osx/windows, but these instructions assume that you will be running linux and will be using the tomcat6 server to host the servlet.

To run this search server you will also need to have a MusicBrainz database with the core data set loaded. Please see

 FIXME: link to ngs server install here.

for details on how to setup at least a "database only install". This document assumes that you have completed the setup of this server.

You will also need a freedb dump, which you can download from http://www.freedb.org/en/download__database.10.html .

You will also need these tools:

In a recent Ubuntu, you can install these with this command:

   apt-get install openjdk-6-jdk maven2 tomcat6

Ensure default Java installation is at least 1.6, and that you have the JDK installed not just the JRE.

   java -version

If you're not on Ubuntu, you can get an official version from http://java.sun.com/javase/downloads and setup Java Home directory in your profile (not needed on ubuntu):

   export JAVA_HOME="/usr/bin/java"

To build you need to install Maven, if you havent already got it. Download it from http://maven.apache.org/download.html .

Download the search server and schemas

You will obviously need the search server, but you also need the musicbrainz schema files:

svn co http://svn.musicbrainz.org/mmd-schema/trunk mmd-schema
svn co http://svn.musicbrainz.org/search_server/trunk search_server

Install the schema classes

Enter the brainz-mmd2-jaxb directory in mmd-schema, and run "mvn install".

 warp@bo-bomb:~/code/mmd-schema/brainz-mmd2-jaxb$ mvn install

You should see it install mmd2-2.0.0.jar in a directory where maven2 will be able to find it later:

 [INFO] Installing /home/warp/code/mmd-schema/brainz-mmd2-jaxb/target/mmd2-2.0.0.jar to /home/warp/.m2/repository/org/musicbrainz/mmd2/mmd2/2.0.0/mmd2-2.0.0.jar

Build the search server servlet

Enter the search_server directory and run "mvn package" to build the servlet.





10:04 < ijabz> Step 1: Check out mdd-schema repository from subversion
10:04 < warp> ok, I have that.
10:06 < ijabz> cd brainz-mmd2-jaxb
10:06 < ijabz> mvn install
...
10:09 < warp>  Installing /home/warp/code/mmd-schema/brainz-mmd2-jaxb/target/mmd2-2.0.0.jar to /home/warp/.m2/repository/org/musicbrainz/mmd2/mmd2/2.0.0/mmd2-2.0.0.jar
10:09 < warp> so, I can now run "mvn package" again?
...
10:16 < ijabz> That is what runs on the server, but first you need to build the indexes
10:16 < ijabz> cd /home/warp/code/search_server/index/target
10:17 < ijabz> I would suggest we just run some test indexes for now, these will build quickly
...  
10:21 < ijabz> java -Xmx 500m -jar index-2.0-SNAPSHOT-jar-with-dependencies.jar -?
10:21 < ijabz> shows the options
...
10:31 < ijabz> try java -Xmx512M -jar index-2.0-SNAPSHOT-jar-with-dependencies.jar -d musicbrainz_db -u warp -p (password) -s warp -w (password) -t
10:31 < warp> I just added the raw database fields, and it started doing stuff now.
10:32 < ijabz> :), so have you got tomcat installed yet ?
10:32 < warp> yes
10:33 < warp> or well... I unpacked it and ran bin/startup.sh, and now something is listening on http://localhost:8080
10:33 < ijabz> Which tomcat download did you use ?
10:33 < warp> apache-tomcat-6.0.24
10:34 < ijabz> ok so you need to coy searchserver,.war into the webpps folder and rename to ROOT.war
10:35 < warp> I can do that while tomcat is running, right?
10:35 < ijabz> Yes
10:35 < ijabz> But do you have a ROOT folder within webaps
10:35 < warp> yes
10:36 < ijabz> ok, I think you have to shutdown and restart for change to take effect
10:36 < ijabz> bin/shutdown.sh; bin/startup.sh
...
10:44 < ijabz> And I meant to say you needed to delete that ROOT folder
10:44 < ijabz> so please do that, then shutdown and restart again
10:44 < warp> aah :)
10:45 < warp> yay, it created a new ROOT now.
10:48 < warp> HTTP Status 500 - Error during servlet initialization directory '/home/search/indexdata/artist_index' does not exist
10:49 < warp> ijabz: how do I tell it where my indexes are?
10:50 < ijabz> I thought you created them in the default location .... yo need to edit /webapps/ROOT/WEB-INF/web.xml
10:50 < warp> (where are my indexes? :)
...
10:52 < ijabz> I think index defaults to building them in a folder called data
10:52 < ijabz> from whereever you run it
10:52 < warp> ah, yes, there they are.
10:52 < ijabz> Ok, specify that path in web.xml then
10:52 < warp> do I have to shutdown tomcat for that?
10:53  * warp does so, just to be sure.
10:54 < alastairp> to change web.xml - yes
