How to install and configure mySQL on Windows

Before going to install mySQL, first lets check whether we have already installed mySQL on the PC. Go to the command prompt and type 'mysql' and press Enter key.
If it is not installed you will get an error message saying 'mysql is not reconnized as an internal or external command, operable program or batch file'. Now lets look at how to install it.
First you need to have the MySQL community server. You can download the installer package from this link. Select the platform as 'Microsoft Windows' and download the MSI installer according to your operating system (either 32 bit or 64 bit). 
Once you have downloaded the MSI package, it will appear like this.
Double click on the installer and run it. The the following window appears. 

Click Next.
select 'I accept the terms in the license agreement' and click Next.
Now you need to select the setup type. I'll select 'Typical and click Next.
Now it shows the destination folder of the installation. Click 'Install'.
It may take few minutes. For the next dialogue boxes appear, click Next.

Now you get the following window.
Tick 'Configure the MySQL Server now' and click 'Finish'.

Click Next.

Select 'Standard Configuration' and click Next.
Make the selections as in the above image and click Next.
Select 'Modify Security Settings' and type the root password. This password is needed when we do modifications to the server so don't forget it. Click Next.
Click 'Execute'.
Click Finish. Now we have successfully installed the mySQL server on the PC.
Go to command prompt and type 'mysql' and press Enter.
Now we are getting an error message because it cannot identify the user. So lets create a user account on the server. First you need to login to the root account. Type the following in the command prompt and press Enter.

mysql -u root -p

It will prompt to enter the root password. Type your root password and press enter.

Now you are in the root account. So lets create a user. The commands are shown in the image below. Don't forget to put semicolons (;) at the end of each statement.

CREATE USER username ;
UPDATE mysql.user SET Password = PASSWORD ('your password') WHERE User = 'username' ;
exit ;

Here I have granted all the permission for this user also. If not you can grant permissions for a selected set of commands. Setting a password for the account is optional. You need to change the words appearing in red color.

If you didn't set a password for the account, this is the command to login to the account.

mysql -u username

If you set a password this is the command to login.

mysql -u username -p

Then it will prompt to enter the password of the account. Type it and press enter.

Instead of command prompt, you can also use the 'MySQL Command Line Client'. You can find it in 
Start -> All Programs - > MySQL - > MySQL Server 
if you are using Windows 7.

From my next post I'll show you some important commands in mySQL. So keep in touch.
