MySQL for CrowdID
Follow the steps below to connect CrowdID to MySQL.
1. Configure MySQL
- Create a database user which CrowdID will connect as (e.g. crowduser).
Create a database for CrowdID to store data in (e.g. crowdiddb).
This must be a different database from the one used by Crowd.
For a UTF-8 encoded database:create database crowdiddb character set utf8;- Ensure that the user has permission to connect to the database, and create and populate tables.
2. Copy the MySQL Driver to your Application Server
- Download the latest MySQL Connector/J JDBC driver.
- Add the MySQL JDBC driver jar (
mysql-connector-java-3.x.x-bin.jar) to the following directory:- For Crowd distribution:
- Crowd 2.0.2 or later: {
CROWD_INSTALL}/apache-tomcat/lib/. - Crowd 2.0.1 or earlier: {
CROWD_INSTALL}/apache-tomcat/common/lib/.
- Crowd 2.0.2 or later: {
- For Crowd WAR distribution, copy the driver JAR to your application server. For example, on Tomcat:
- Tomcat 5.5.x:
common/lib/. - Tomcat 6.x:
lib/.
- Tomcat 5.5.x:
- For Crowd distribution:
Do not place the Debug Driver (mysql-connector-java-3.x.x-bin-g.jar) on the CLASSPATH as this can cause issues. (JRA-8674).
3. Configure your Application Server to Connect to MySQL
Edit the file
apache-tomcat-X.X.XX/conf/Catalina/localhost/openidserver.xmland customize the username, password, driverClassName and urlparameters for the Datasource.<Context path="/openidserver" docBase="../../crowd-openidserver-webapp" debug="0"> <Resource name="jdbc/CrowdIDDS" auth="Container" type="javax.sql.DataSource" username="[enter db username here]" password="[enter db password here]" driverClassName="com.mysql.jdbc.Driver" url="jdbc:mysql://localhost/crowdiddb?autoReconnect=true&useUnicode=true&characterEncoding=utf8" [ delete the minEvictableIdleTimeMillis, timeBetweenEvictionRunsMillis and maxActive params here ] /> <Manager className="org.apache.catalina.session.PersistentManager" saveOnRestart="false"/> </Context>The URL above assumes a UTF-8 database — i.e. created with
create database crowdiddb character set utf8;.MySQL closes idle connections after 8 hours, so the
autoReconnect=trueis necessary to tell the driver to reconnect.- Delete the minEvictableIdleTimeMillis, timeBetweenEvictionRunsMillis and maxActive attributes (which are only needed for HSQL, and degrade performance otherwise).
4. Configure CrowdID to use MySQL
Edit the
build.propertiesfile (located in the root of the Crowd distribution, not Crowd EAR-WAR) and modify the hibernate.dialect to the following. Please choose only one of the 3 available options depending on how you have configured your database server.*For MySQL set:* hibernate.dialect=org.hibernate.dialect.MySQLDialect *For MySQL with InnoDB set:* hibernate.dialect=org.hibernate.dialect.MySQLInnoDBDialect *For MySQL with MyISAM set:* hibernate.dialect=org.hibernate.dialect.MySQLMyISAMDialect- Then run
./build.shorbuild.bat. This will configure CrowdID to use the MySQL dialect.
If you do not wish to edit this file and run the build script, you can edit the jdbc.properties (which the above script modifies) directly. The jdbc.properties file is located here: crowd-openidserver-webapp\WEB-INF\classes\jdbc.properties. Modify the file to the following:
# - Crowd Configuration Options
hibernate.connection.datasource=java\:comp/env/jdbc/CrowdIDDS
hibernate.dialect=org.hibernate.dialect.MySQLDialect
hibernate.transaction.factory_class=org.hibernate.transaction.JDBCTransactionFactory
...
次のステップ
You should now have an application server configured to connect to a database, and CrowdID configured to use the correct database. Now start up CrowdID and watch the logs for any errors.
