Hi! You can run multiple servers on any Windows version with any MySQL version. They must NOT share any data, .frm, or log files.
Below Miguel explains how with MySQL-4.0.2 you can run multiple instances also as Windows services. For any MySQL version you can do like this: You have to create a separate my.cnf file for each instance, configure a different port number for each instance, and start each mysqld instance from an MS-DOS prompt like this: > mysqld --defaults-file=your_path_to_the_my_cnf_of_this_instance --console You can use the mysql.exe client to query each instance like this: > mysql --defaults-file=your_path_to_the_my_cnf_of_the_instance Below is the relevant portion of the my.cnf file of a slave mysqld in my own Windows computer. The master uses the default port number of mysqld, 3306. I have set the slave port number to a different value, 3308. [mysqld] port=3308 master-host=omnibook master-user=slaveuser master-password=slaveuser master-port=3306 server-id=2 basedir=c:/slave datadir=c:/slave/data innodb_data_home_dir=e:/ibdataslave innodb_data_file_path=ibdata4:10M:autoextend innodb_log_group_home_dir=c:/slave/data innodb_log_arch_dir=c:/slave/data Best regards, Heikki Tuuri Innobase Oy --- Order technical MySQL/InnoDB support at https://order.mysql.com/ See http://www.innodb.com for the online manual and latest news on InnoDB Copied message from Miguel: ...........................

For example: For to run two services: the first one using mysqld-nt.exe and the second one using the mysqld-max-nt.exe. Installing mysqld-nt.exe command at the prompt: mysqld-nt --install or mysqld-nt --install-manual Installing mysqld-max-nt.exe command at the prompt: mysqld-max-nt --install mysqldopt or mysqld-max-nt --install-manual mysqldopt Now you have the default service called mysql for to run mysqld-nt.exe and the service mysqldopt for to run mysqld-max-nt.exe. Now you edit the /winnt/my.ini file: [mysqld] #for to set the server mysqld-nt.exe port=3306 basedir=c:/mysql datadir=c:/mysql/data ..... [mysqldopt] #for to set the server mysqld-max-nt.exe the same name of #the service port=3307 basedir=c:/mysql datadir=d:/mysqldopt/data skip-innodb skip-bdb ..... Notes: 1- You can use the same basedir but not the same executable. 2- You must to have a different datadir (the whole directory) for each server. You can't to mix the mysql database and the working databases. 3- You need to have a different port. In this way for example you can use one server as master and the other as slave on the same machine; of course both handling the same type of tables. In the example above only MyISAM tables.
