======================
Single VM/Site install
======================
Local Installation
------------------
Prerequisites
If you are using a VM make sure it has at least 8 GB of RAM (It may work with 4 GB, but with 2 GB it
does give issues).
Instructions
- Create MUSIC Install dir /opt/app/music
- Open /etc/hosts as sudo and enter the name of the vm alongside localhost in the line for 127.0.0.1. E.g. 127.0.0.1 localhost music-1. Some of the apt-get installation seem to require this.
- Ensure you have OpenJDK 8 on your machine.
- 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
- By the end of this you should have Cassandra working.
- Download Apache Zookeeper 3.4.6, install into /opt/app/music and follow these instructions https://zookeeper.apache.org/doc/r3.4.6/zookeeperStarted.html pertaining to the standalone operation. By the end of this you should have Zookeeper working.
- 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).
- Create a music.properties file and place it in /opt/app/music/etc/. Here is a sample of the file:
music.properties::
music.properties
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
cassandra.password=cassandra1
# AAF Endpoint
#aaf.endpoint.url=<aaf url>
- Make a dir /opt/app/music/logs MUSIC dir with MUSIC logs will be created in this dir 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::
authenticator: PasswordAuthenticator
authorizer: CassandraAuthorizer
2. Restart Cassandra
3. Login to cqlsh with default credentials::
cqlsh -u cassandra -p cassandra
4. To change default user create new user with the following command.::
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::
ALTER USER cassandra WITH PASSWORD ‘SomeLongRandomStringNoonewillthinkof’;
6. Provide the new user credentials to Music. Update music.properties file and uncomment or add the following::
cassandra.user=<new_user>
cassandra.password=<new_password>
To access keyspace through cqlsh, login with credentials that are passed to MUSIC while creating the keyspace.
Continue with `Authentication <./automation.rst>`_
