Re: Multiples instances of MySQL
Hi! Ok, the appropriate parameter mysqld --defaults-file=your_path_to_my_cnf already exists with which you can explicitly specify what my.cnf file mysqld reads in. Regards, Heikki Date: Sun, 30 Dec 2001 23:23:18 To: [EMAIL PROTECTED] From: Heikki Tuuri [EMAIL PROTECTED] Subject: Re: Multiples instances of MySQL Hi! You could try the following: make Windows batch files where you give all options to mysqld-max.exe on the command line: instance1.bat: mysqld-max --port=3306 --socket=... --datadir=... --basedir=... --innodb_data_home_dir=... --set-variable=innodb_buffer_pool_size=30M ... instance2.bat: mysqld-max --port=3307 --socket=... ... I hope we do not run over the command line length limit! But with the above you can get rid of my.ini and my.cnf altogether, or put just the shared starup parameters to my.cnf. Actually, Monty should add a startup option to mysqld: --read_this_my_cnf=a_path_to_my_cnf_file where you could tell from what location this instance of mysqld should read its startup parameters. I am forwarding this email to Monty too. He can consider adding the above startup option. Automatically searched my.cnf files cause constant confusion.

Re: Multiples instances of MySQL
Hello all, I'm in a spot, I'm managing to successfully run several instances of MySQL, say on port=3306 and port=3308. When I use shutdown, the instance which started first shuts down. To shutdown the instance started on port 3306, I use; mysqladmin -P 3306 -u root -p2000 shutdown And to shutdown the instance started on port 3308, I use; mysqladmin -P 3308 -u root -p2000 shutdown However, the instance which started first is always the instance which shuts down, irrespective of the port number I provide. Could someone please advise and/or point me. Thank you provisionally for any assistance.

Re: Multiples instances of MySQL
use --socket instead of -P would solve your problem. without -h, socket file is used for connection. since you've not specified the socket file, the default socket file path is used (in some case, /tmp/mysql.sock). that's why you're always shutting down the first one. Happy new year.

Hi!

Re: Multiples instances of MySQL
Hello Heikki, Note, this is a duplicate posting - erroneously posted against 'General database questions'. Thank you very much for this note and your valued assistance. I have the different instances of MySQL running with your proposal to add the lot to a bat file. And yes, if such a option as you propose exists, others would possibly get multiple instances / my.cnf files working more easily. BTW, I wasn't aware that I could place the InnoDB options as options on the command line. They are not mentioned as command line options in chapter 4.1.1. So it was extremely helpful that you gave me that pointer. Either way thank you again for an excellent feature and also for your clear assistance.
