Quickstart

A short guide for the impatient!

Prerequisites:

A running MySQL database

test

, with user

test

and password

test

, a table

orders

A terminal / console with commands

curl

and

unzip

Internet access (of course)

Let's go!

Download elasticsearch (current version is 0.19.8, check for the most recent version on
http://elasticsearch.org) from

curl -OL https://github.com/downloads/elasticsearch/elasticsearch/elasticsearch-0.19.10.zip[/code] 
Unpack zip file into you favorite elasticsearch directory, we call it $ES_HOME

cd $ES_HOME


unzip path/to/elasticsearch-0.19.10.zip


Install JDBC river plugin (current version is 1.3.2, check for the most recent version, and if you have the file permissions to write into the
plugins
 folder). If you have installed a JDBC river plugin before, it is recommended to remove the folder
plugins/river-jdbc
 before installing a new version. (**Note**: If you're using a version of elasticsearch >= 0.90.0, you need to use at least version 2.2.0 of the river-jdbc plugin).

./bin/plugin --url http://bit.ly/10FJhEd -install river-jdbc


Download MySQL JDBC driver (current version is 5.1.21, check for the most recent version)

curl -OL http://dev.mysql.com/get/Downloads/Connector-J/mysql-connector-java-5.1.21.zip/from/http://cdn.mysql.com/[/code] 
Add MySQL JDBC driver jar to JDBC river plugin directory

cp mysql-connector-java-5.1.21-bin.jar $ES_HOME/plugins/river-jdbc/


Start elasticsearch in terminal window with logging on the console

./bin/elasticsearch -f


Start another terminal window, and create a new JDBC river with name 
my_jdbc_river
 with this
curl
 command

curl -XPUT 'localhost:9200/_river/my_jdbc_river/_meta' -d '{
"type" : "jdbc",
"jdbc" : {
"driver" : "com.mysql.jdbc.Driver",
"url" : "jdbc:mysql://localhost:3306/test",
"user" : "test",
"password" : "test",
"sql" : "select * from orders"
},
"index" : {
"index" : "jdbc",
"type" : "jdbc"
}
}'


The river runs! Watch the log on the elasticsearch console for the river activity. When the river fetched the data and is going to wait for the next cycle (which is by default 60 minutes ahead), you can query your elasticsearch node for the data you just
indexed with the following 
curl
 command

curl -XGET 'localhost:9200/jdbc/jdbc/_search?pretty&q=*'


Enjoy the result!

If you want to stop the 
my_jdbc_river
 river fetching data from the
orders
 table after the quick demonstration, use this 
curl
 command:

curl -XDELETE 'localhost:9200/_river/my_jdbc_river'


What next?
Now, if you want more fine-tuning, you can drop the index 
jdbc
, change the mapping, change the index name or type name, change the river creation settings, play with the data fetch interval - whatever you like.
