How To Install and run MySQL

How to install and run the MySQL


Step to install and work on the MySQL Server


Step 1 : Download the MYSQL

Download the MySQL and install the MySQL into C:\mysql.
Extract the ZIP to your C: drive and rename the folder from “mysql- x.x.xx-win32″ to “mysql”. MySQL can be installed anywhere on your
system.

Step 2 : Move the data folder(optional)


I recommend placing the data folder on another drive or
partition to make backups and re-installation easier. For the
purposes of this example, we will create a folder called
D:\MySQLdata and move the contents of C:\mysql\data into it.

You should now have two folders, D:\MySQLdata\mysql and
D:\MySQLdata\test. The original C:\mysql\data folder can be
removed.

Step 3 : Create the configuration file

MySQL provides several configuration methods but, in general, it
is easiest to to create a my.ini file in the mysql folder. There
are hundreds of options to tweak MySQL to your exact
requirements,

but the simplest my.ini file is:

[mysqld]
# installation directory
basedir="C:/mysql/"
# data directory
datadir="C:/MySQLdata/"


Step 4 : Test your MySQL Server

Open the command prompt and run the following command

C:\mysql\bin\mysqld.exe
This will start the MySQL server which listens for requests on
localhost port 3306.
Open another command window and run the following command

cd c:\mysql\bin
mysql –u root

This will show a welcome message and the mysql> prompt.
Enter “show databases;” to view a list of the pre-defined
databases

Step 5: Change the root password

The MySQL root user is an all-powerful account that can create and
destroy databases. If you are on a shared network, it is advisable
to change the default (blank) password. From the mysql> prompt,
enter:

UPDATE mysql.user SET password=PASSWORD("my-new-password") WHERE
User='root';

FLUSH PRIVILEGES;

You will be prompted for the password the next time you start the
MySQL command line.

Enter “exit” at the mysql> prompt to stop the command line client.
You should now shut down MySQL with the following command:

Step 6 : Create Table in database velsDB

First we need to Create a database :

mysql> create database velsDB ;
mysql>use database velsDB;

create table resource_vacation_plan(
employee_id varchar(36) not null,
employee_name varchar(32) not null,
start_date date,
end_date date,
no_of_days integer(3)
);

Commit;

If you are going to use my sql in your code the use the following
to create the DB connection:

String DB_MYSQL_DRIVER_NAME = "com.mysql.jdbc.Driver";
String DB_URL_STRING_MYSQL = "jdbc:mysql://localhost:3306/velsDB";
String DB_URL_MYSQL_USERID = "root";
String DB_URL_MYSQL_PASSWORD = "root";
