MUSIC Installation Instructions

Cassandra Installation

...

• Download Apache Cassandra 3.0, install into /opt/app/music and follow these instructions http://cassandra.apache.org/doc/latest/getting_started/installing.html till and including Step

• Create a user in Cassandra

  1. Edit conf/cassandra.yaml file

     Code Block
     language bash theme Midnight
     authenticator: PasswordAuthenticator authorizer: CassandraAuthorizer

  2. Restart Cassandra

  3. Login to cqlsh with default credentials (cqlsh can be found in $CASSANDRA_HOME/bin directory)

     Code Block
     language bash theme Midnight
     ./cqlsh -u cassandra -p cassandra

  4. Change default user create new user with the following command. Fill in a username/password below and remember this username/password for music properties.

     Code Block
     language sql theme Midnight
     CREATE USER <new_user> WITH PASSWORD ‘<new_password>’ SUPERUSER;

  5. Change password for default user ‘cassandra’ so that no one will be able to login without proper authorization:

     Code Block
     language sql theme Midnight
     ALTER USER cassandra WITH PASSWORD ‘<SomeLongRandomStringNoonewillthinkof>’;

• Test to make sure Cassandra is running correctly by accessing it through cqlsh using the credentials created in step 4.

  Code Block
  language bash theme Midnight
  ./cqlsh -u <new_user> -p <new_password>

Zookeeper Installation

• By the end of this you should have Cassandra working.
• Download Apache Zookeeper 3.4, install into /opt/app/music and follow these instructions https://zookeeper.apache.org/doc/r3.4.11/zookeeperStarted.html pertaining to the standalone operation. By the end of this you should have Zookeeper working.

Tomcat Installation

• Download the Version 8.5 Apache Tomcat and install it using these instructions  https://tomcat.apache.org/download-80.cgi (this is for version 8.5) into /opt/app/music/.
• Follow RUNNING.txt instructions for completing tomcat installation. This file can be found in the tomcat directory. Or look at https://tomcat.apache.org/tomcat-8.5-doc/setup.html#Introduction for more in depth instructions

Music Installation

• Create a music.properties file and place it in /opt/app/music/etc/.
• Here is a sample of the file:, the cassandra.user & cassandra.password should be replaced by your values from step 4 of Cassandra installation above.

my.id=0
all.ids=0
my.public.ip=localhost
all.public.ips=localhost
#######################################
# Optional current values are defaults
#######################################
# If using docker this would point to the specific docker name.
#zookeeper.host=localhost
#cassandra.host=localhost
#music.ip=localhost

#debug=true
#music.rest.ip=localhost
#lock.lease.period=6000
# Cassandra Login - Do not user cassandra/cassandra
cassandra.user=cassandra1<new_user>
cassandra.password=cassandra1<new_password>
# AAF Endpoint
#aaf.endpoint.url=<aaf url>

• Make a

  dir /opt/app/music/logs MUSIC dir with MUSIC

  directory for MUSIC logs. The logs will be

  created in this dir

  placed here after MUSIC starts

  .
• Build the MUSIC.war and place in tomcat webapps dir. 
• Authentications/AAF Setup For Authentication setup.
• Start tomcat and you should now have MUSIC running.

Extra Cassandra information for Authentication:

To create first user in Cassandra

1. Edit conf/Cassandra.yaml file

• Code Block
  language bash theme Midnight

...

authenticator: PasswordAuthenticator
authorizer: CassandraAuthorizer

1. Restart Cassandra
2. Login to cqlsh with default credentials

cqlsh -u cassandra -p cassandra

1. To change default user create new user with the following command.

CREATE USER new_user WITH PASSWORD ‘new_password’ SUPERUSER;

1. Change password for default user ‘Cassandra’ so that no one will be able to login

ALTER USER cassandra WITH PASSWORD ‘SomeLongRandomStringNoonewillthinkof’;

...

To access keyspace through cqlsh, login with credentials that are passed to MUSIC while creating the keyspace.

...

Build Music

Documentation will be updated to show that. Code can be downloaded from Music Gerrit. 
To build you will need to ensure you update your settings with the ONAP settings.xml (Workspace and Development Tools)

Once you have done that run the following:

• title music.properties

  mkdir /opt/app/music/logs

• Download MUSIC from the Music Gerrit into your music folder (/opt/app/music/)

  Code Block
  language bash theme Midnight

...

cassandra.user=<new_user>
cassandra.password=<new_password>

• cd /opt/app/music/ git clone https://gerrit.onap.org/r/music

• Build music using maven

• Code Block
  language bash theme Midnight
  cd music # If you installed settings.

...

• xml in your ./m2 folder mvn clean package

...

• If the build is successful,

...

• you will find the MUSIC.war in the ./target folder. Copy this to your tomcat's webapp folder

...

• Code Block
  language bash theme Midnight
  cp target/MUSIC.WAR $TOMCAT_HOME/webapps

• Start tomcat and you should now have MUSIC running.

• There is a folder called postman that contains a postman collection for testing with postman.
