Configure Server Install MySQL-Server First you need to install an MySQL server. On Debian-based distributions like Ubuntu you can use sudo apt-get install mysql-server mysql-client to install it. You will be asked to specify a password for the root-account for the database. The mysql-client package is needed in order to execute some of the commands in this document, but it's not fundamental to the use of Amarok. Configure Database Connect to the local database using mysql -u root -p You will be prompted for the password for MySQL's root user. You will get the mysql> prompt. Create a new user amarokuser with the password amarokpass using the CREATE USER 'amarokuser'@'localhost' IDENTIFIED BY 'amarokpass'; command. Amarok needs its own database, which is created with CREATE DATABASE amarokdb; Give the new user access to the database by entering the GRANT ALL ON amarokdb.* TO 'amarokuser'@'%' IDENTIFIED BY 'amarokpass'; command, where % is a wildcard to allow all hosts to connect to the database. Now use the FLUSH PRIVILEGES; statement to reload various internal caches used by MySQL. Finally exit closes the MySQL prompt. By default the server can only be accessed by the local host. To change this you need to edit the file /etc/mysql/my.cnf and adjust the address near bind-address to the one your server listens on the network. 0.0.0.0 listens on all interfaces. After that you need to restart the server using sudo service mysql restart Configure Client Open the configuration dialog by clicking Settings -> Configure Amarok -> Database. Enable the checkbox and enter the user data. You need to restart Amarok so that the changes take effect. Migrating from MySQL Embedded to MySQL Server If you want to maintain the statistics, etc. that you have in the embedded MySQL database from before Amarok 2.2, you can do the following: First, start Amarok 2.2+ at least once to give the database a chance to update to the latest schema version. Next, kill the running MySQL service sudo /etc/init.d/mysql stop and start a MySQL daemon from your ~/.kde4/share/apps/amarok directory (--defaults-file MUST be the first option!): /usr/sbin/mysqld --defaults-file=`pwd`/my.cnf --default-storage-engine=MyISAM --datadir=`pwd`/mysqle --socket=`pwd`/sock --skip-grant-tables The skip-grant-tables means you can use any password or username to connect to it. 'localhost' will not work, the MySQL client will try to use a Unix socket. Using 127.0.0.1 as the host makes it work. Some systems may restrict this access through apparmor or SELinux. They can be temporarily disabled with sudo /etc/init.d/apparmor stop Now, run mysqldump, passing in the -S option to specify the local socket. This will dump your old embedded DB out to a SQL file. mysqldump -S sock amarok > amarok.mysql You can then restart your MySQL service and load this SQL file into your MySQL server. You'll have needed to already run the GRANT statement above and create an Amarok database ("CREATE DATABASE amarok;"): sudo /etc/init.d/mysql stop mysql -u amarokuser -p amarok < amarok.mysql Note You may need to re-scan your collection in Amarok after completing this. ← UPnP ↑ Back to Menu ↑ Working with Media Devices → Retrieved from "https://userbase.kde.org/index.php?title=Amarok/Manual/Organization/Collection/ExternalDatabase/en&oldid=417801" Categories: AmarokMultimediaTutorials This page was last edited on 3 March 2019, at 18:00.
