Lee,
Openmeetings will use the current database, which you need to DROP if you are going to keep the same database name. If you want to have two installations so you can compare between them, when you are installing the second instance you can easily change the name of the "openmeetings database that you are creating and the name of the database in the persistence.xml file. Of course you would have to install openmeetings into folder by another name, this is not something that I have ever bothered to do, but I believe would work. Step 4 - Install MySQL and configure OpenMeetings database apt-get install mysql-server mysql -u root -p CREATE DATABASE openmeetings DEFAULT CHARACTER SET 'utf8'; GRANT ALL PRIVILEGES ON openmeetings. * TO 'openmeetings'@'localhost' IDENTIFIED BY 'yourpassword' WITH GRANT OPTION; vi /usr/lib/red5/webapps/openmeetings/WEB-INF/classes/META-INF/persistence. xml Change the Username and Password to those you created in MySQL. Note: if you want OpenMeetings to use an external database or your MySQL is listening to a network address and not 127.0.0.1, then you can replace "localhost" with your MySQL Server's IP address. , Url=jdbc:mysql://localhost:3306/openmeetings?... , Username=openmeetings , Password=yourpassword"/> ============================================ Step 4 - Install MySQL and configure OpenMeetings database apt-get install mysql-server mysql -u root -p CREATE DATABASE openmeetings2 DEFAULT CHARACTER SET 'utf8'; GRANT ALL PRIVILEGES ON openmeetings2. * TO 'openmeetings'@'localhost' IDENTIFIED BY 'yourpassword' WITH GRANT OPTION; vi /usr/lib/red5/webapps/openmeetings2/WEB-INF/classes/META-INF/persistence .xml Change the Username and Password to those you created in MySQL. Note: if you want OpenMeetings to use an external database or your MySQL is listening to a network address and not 127.0.0.1, then you can replace "localhost" with your MySQL Server's IP address. , Url=jdbc:mysql://localhost:3306/openmeetings2?... , Username=openmeetings , Password=yourpassword"/> Thanks, George Kirkham From: Lee Saunders [mailto:leesenglishless...@gmail.com] Sent: Sunday, 23 February 2014 12:13 AM To: user@openmeetings.apache.org Subject: Are side-by-side installations possible? Hello, I am running OM 2.1.1, but would like to see how 2.2 compares. If I unpack 2.2 into a new folder on my drive (windows desktop), will OM create a new MySQL database or overwrite the existing one? Thanks, Lee.
