Today's problem is this, has been installed before MySQL, has been used well, but today opened the service times abnormal, unable to start. In order to save trouble, so think of unloading load, in the process of installation found that 3306 has been occupied, this is the beginning of the service can not start the reason. See someone said with FPort view port number, so downloaded, found that Win7 can't use (very awkward AH). Finally, it is viewed with a command:
Netstat-aon|findstr 3306
This will show that the process ID takes up 3306 ports.
Then in the Execute tasklist command to find the process name based on the process ID, in Task Manager you can right-click to choose to view the file location, you can also end the process, so that the installation of MySQL is no problem.
I hope you have some help with the same problem.
