I guess the next question is how do I check to see whats going on here. The error says that you tried to start another server, listening in the same (default) port 3306, which is not possible. Try to start in a different port (like 33306, or 3307). How do you start mysql? A suggest create a different start script for the other databases (/home/mysql), that uses a different my.conf, where you have the other parameters on the database I tried telnet 192.168.0.5:3306 and got the following [EMAIL PROTECTED] log]# telnet 192.168.0.5:3306 192.168.0.5:3306/telnet: Name or service not known This may suggest that telnet is not installed, or it may indicate another problem You used the wrong syntax, you should have tried # telnet 192.168.0.5 3306 (With a space instead of a semicolon) It should prompt you with some imperceptible data, where you can see the version of MySQL Server in the middle. Close it with Ctrl+D Any suggestions are welcome TIM -- Nuno Pereira email: [EMAIL PROTECTED] -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

Re: Databases in a different location than the default
Hi Tim, all! Tim Holmes wrote: [[...]] My databases are located on a different physical machine from the one running the database server - (for backup etc reasons) IMO, this is a no-no: You add complexity and (potential) bottlenecks to your setup. You should store your data local to the machine running the server processes, because several operations (like locking) are only possible on local files / disks. Rather do remote backups than remote routine operation. (This does not imply that backup were no routine activity!) The databases reside in /home/mysql - that's an NFS share, which I know for a fact is valid, as I have other data being used from the share NFS is a good example: Typically, it does not support locking.
