Hi, guys, This is Jing. I need a favor. I am trying to run two mysql servers on one machine. But I do not know how to do it correctly. I created a database using mysql, the database is a part of our product. And meantime, we have another mysql with the third party software(AdventNet). My high designer wants that we run two servers together on one machine(NT or Sun Solaris 5.8). I read the mysql manual "11. Replication in mysql". But I am not sure if it is right way for this situation. And also I cannot understand well what it talked in the manual. Could you please give me some help? Where is the file that named my.cnf? Do I need to create it or does it already exist? Thank all of you, and have a good day, Jing Chen
