installed Xampp on Windows 7 32-bit. Errors when starting

问题

When I try to start MySql in XAMPP control panel (v3.2.1) I have the following message and MySql does not start.

23:02:03  [mysql]   Problem detected!
23:02:03  [mysql]   Port 3306 in use by ""C:\Program Files\MySQL\MySQL Server 5.1\bin\mysqld" --defaults-file="C:\Program Files\MySQL\MySQL Server 5.1\my.ini" MySQL"!
23:02:03  [mysql]   MySQL WILL NOT start without the configured ports free!
23:02:03  [mysql]   You need to uninstall/disable/reconfigure the blocking application
23:02:03  [mysql]   or reconfigure MySQL and the Control Panel to listen on a different port
23:02:03  [mysql]   Attempting to start MySQL service...

回答1:

The port 3306 is already in use in your machine, so you need to change the port number to 3307 in my.ini in C:\xampp\mysql\bin\my.ini.

Once done restart the Apache server.

回答2:

To change the port successfully, you have to change the port number in following files in the mentioned manner.

1. You can change the port number to 3306 from 3307 in \xampp\mysql\bin\my.ini file in a couple of places.
2. There is also a couple of default MySQL port settings in the \xampp\php\php.ini file that would also need changing.
3. Save the files and restart Apache and MySQL to test.

Also make sure you run it as administrator (always helps)
