45. Change Apache Port on Mac  In Manage Servers tab, choose to highlight Apache Web Server and click on Configure.

46. Change Apache Port on Mac  Change 80 to any port above 1024. Since anything below it is a reserved port. For example 8080 and restart server.

47. Change Apache Port on Mac  Now  http://localhost/xampp doesn’t work anymore but http://localhost/xampp  http://localhost:8080/xampp is now active http://localhost:8080/xampp

48. Fix on Windows  On windows you’ll clock on Config in the top right corner.  Then you’ll click on Service and Port Settings in the new window an you’ll change 80 to 8080 in the new window and you’ll need to also save

In case the GUI didn’t work  Go to:  Mac OS X: “/Applications/XAMPP/xampfiles/etc/”  Windows: :\apache\conf\  Open the file:  httpd.conf  Apply following changes:  Find the line which specifies the port number “Listen 80” It should be at line 58 in Windows and 52 In Mac  Change the port from 80 to anything you desire  Save and exit the file  Restart apache server  Test it  Localhost:

52. Safety Issues  If you visit the security status page  http://localhost/security/index.php http://localhost/security/index.php  if not working, visit http://localhost/http://localhost/ Click “English” Click “Security” on left side bar  You will se that there are three security errors

53. To fix this on Mac  Run  sudo /Applications/XAMPP/xamppfiles/xampp security  Then open MySQL config file using the menues and find the line with:  #password= your_password  Remove # and change “your_password” to any password you desire.
