Resin MySQL and RDS setup with Amazon RDS
From Resin 3.0
This is a continuance of our earlier tutorial on Resin cloud deploy on Amazon.
Install MySQL on local box
First let's install MySQL create a user called bloguser with a password. Then let's create a database called blogdb.
$ sudo apt-get mysql-server
Startup MySQL client tool to create a new user and database:
$ mysql -u root -P
Next create a user called bloguser with the pass roofoo.
mysql> GRANT ALL PRIVILEGES ON *.* TO 'bloguser'@'%' IDENTIFIED BY 'roofoo' WITH GRANT OPTION; Output: Query OK, 0 rows affected (0.00 sec)
Next create a database called blogdb.
mysql> create database blogdb; Output: Query OK, 1 row affected (0.00 sec)
Exit mysql.
mysql> exit; Output: Bye
Use Roo to switch to MySQL
In the examples folder start up roo and switch to using MySQL.
$ roo roo> jpa setup --database MYSQL --provider HIBERNATE --databaseName blogdb Output: Updated SPRING_CONFIG_ROOT/database.properties Please update your database details in src/main/resources/META-INF/spring/database.properties. Updated SPRING_CONFIG_ROOT/applicationContext.xml Updated ROOT/src/main/resources/META-INF/persistence.xml Updated ROOT/pom.xml [added dependency mysql:mysql-connector-java:5.1.18; removed dependency com.h2database:h2:1.3.161]
Find and modify the database properties for this application. (Later we will set this up in JNDI of Resin, but for now just modify the properties file).
$ find . -name "database.properties" Output ./src/main/resources/META-INF/spring/database.properties $ emacs ./src/main/resources/META-INF/spring/database.properties
Add the user name and password that we setup earlier.
#Updated at Thu Dec 01 12:57:30 PST 2011 #Thu Dec 01 12:57:30 PST 2011 database.password=roofoo database.url=jdbc\:mysql\://localhost\:3306/blogdb database.username=bloguser database.driverClassName=com.mysql.jdbc.Driver
Now let's test out what we have so far. Build the project and deploy it to resin.
$ mvn package Output: ... [INFO] BUILD SUCCESS $ resinctl deploy ./target/blog-0.1.0.BUILD-SNAPSHOT.war -name blogm Output Deployed production/webapp/default/blogm from ./target/blog-0.1.0.BUILD-SNAPSHOT.war to hmux://127.0.0.1:6800
Now startup the blogm app and add a blog entry.
$ firefox http://localhost:8080/blogm/
If you like, you can fire up the mysql client and see if your new entry and blog table is in MySQL.
$ mysql -u root -p Enter password: Welcome to the MySQL monitor. Commands end with ; or \g.
