Bug at the end of installation

Postby Herpe » 31. May 2019 19:25

Hi people,

I installed the latest version of xampp on Windows 10 and at the end of the process, a bug happened. I tried to start MYSQL, but it failed and this message appeared :

Error: MySQL shutdown unexpectedly.
14:21:42 [mysql] This may be due to a blocked port, missing dependencies,
14:21:42 [mysql] improper privileges, a crash, or a shutdown by another method.
14:21:42 [mysql] Press the Logs button to view error logs and check
14:21:42 [mysql] the Windows Event Viewer for more clues
14:21:42 [mysql] If you need more help, copy and post this
14:21:42 [mysql] entire log window on the forums

I took a look at LOGS and this is was showed up :

Is not a bug, on your PC the Port 3306 (MySQL) is already in use. Either from another program "Do you already have another mysqld server running on port: 3306 ?" (didnt you read that?), or your firewall is blocking it. Probably you have another MySQL server running.

Last not least, maybe you already started Xampp MySQL and you cannot start it twice.
