How to connect from windows command prompt to mysql command line

The cd in your question is invalid 

cd CD:\MYSQL\bin\

You can't cd to CD:\ anything, because CD:\ isn't a valid directory in Windows. CD: would indicate a drive, except that drives are restricted to a single letter between A and Z. 

If your \MYSQL\BIN is on drive C:, then your commands need to be:

C:\>cd \MYSQL\Bin

C:\MYSQL\Bin>mysql -u root -p admin

-

If you're not already on C: (which you'll know by looking at the prompt in the cmd window), or your MySQL folder is on another drive (for instance, D:), change to that drive too:

C:\> cd /d D:\MYSQL\Bin

D:\MYSQL\Bin>mysql -u root -p admin

-

The .exe after mysql is optional, since .exe is an executable extension on Windows. If you type mysql, Windows will automatically look for an executable file with that name and run it if it finds it.

   $('.scrollToTop').fadeIn();
  } else {
   $('.scrollToTop').fadeOut();

Remove nginx and re activate apache

Remove nginx and re activate apache

 
//First, you need to stop nginx so it releases port 80 so that apache2 can listen to it later on.
-------------------------------------
sudo service nginx stop                                                           

//Next, if nginx was installed with apt-get, removing it would be as simple as

sudo apt-get remove nginx

//Instead, you can also use

sudo apt-get purge nginx

//First one removes all package files, while the second also removes the configuration files.
//If you intend to use nginx later on with the configuration you did, use remove. Else, I would suggest using purge.

//After removing nginx, you can restart apache to make sure it is listening to port 80.

sudo apache2ctl restart

//If you had removed apache before installing nginx, you can re-install it with

sudo apt-get install apache2
