Contents

In this OpenKM release you can create the databases automatically configuring the hibernate.dialect and hibernate.hbm2ddl properties in OpenKM.cfg.

hibernate.dialect=org.hibernate.dialect.MySQL5Dialect
hibernate.hbm2ddl=create

or

hibernate.dialect=org.hibernate.dialect.MySQL5InnoDBDialect
hibernate.hbm2ddl=create

Once the tables are created, OpenKM will automatically change the hibernate.hbm2ddl property from create to none.


Nota advertencia.png This configuration property should be set before the database creation. Once the database has been initialized don't modify it because can damage your installation. If your OpenKM installation has been already configured with another database (default one is an embedded one called HSQL) you can't switch to another database simply changing this property.

More info about this at:

Database creation

Check if your MySQL installation has InnoDB engine enabled:

$ mysql -h localhost -u root -p
mysql> show engines;

Nota clasica.png You can use the org.hibernate.dialect.MySQL5InnoDBDialect dialect and avoid changing the default MySQL Storage Engine.

Edit /etc/mysql/my.cnf and under [mysqld] section in your ini file, add:

default-storage-engine = innodb

Nota clasica.png Starting with OpenKM 6.0, only one database is needed.

Now create databases and user:

DROP DATABASE IF EXISTS okmdb;
 
CREATE DATABASE okmdb DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_bin;
 
CREATE USER openkm@localhost IDENTIFIED BY '*secret*';
GRANT ALL ON okmdb.* TO openkm@localhost WITH GRANT OPTION;

You can check the database engine with:

$ mysqlshow -h localhost -u root -p --status okmdb;
