    Default Laravel Database Migrations

    Laravel allow you to easily create database with database migration.

    First you need to edit

    Code:
    app/config/database.php
    and set the database.

    To create database migration, see

    http://laravel.com/docs/4.2/migrations

    Once database migrations are created, you can run it, so database will be created in MySQL database.

    To create MySQL database from existing Database migration file, run

    Code:
    php artisan migrate
    This command will read migrations file stored in folder

    Code:
    app/database/migrations/
    and create corresponding database tables.

    First of all, you need to run this from project folder, not some random folder.

    As for imagehostnow project, all database migrations are created, check folder

    Code:
    app/database/migrations/
    Since all database migration files are already there, you only need to migrate with the command i given in above post, that will create tables as per migration files already created.

    Check these database migrations files, so you get an idea how it is created, also read laravel documentation.

    Good. Now google and try to find out why that error happend. Try to fix it yourself.

    You may also verify all database information is properly set in laravel configuration file.

    I have connected to mysql server and created a new db called 'imagehostnow' and edited the database info in app/config/database.php file.

    Inserted database name, username and password.

    Then I run following command:

    Code:
    php artisan migrate
    I got below message:

    Then I set permission for www/imagehostnow.com/app/storage/ folder using below command:

    Code:
    chmod -R 777 ~/www/imagehostnow.com/vendor/monolog

    again run below command

    Code:
    php artisan migrate
    But still error got

    This is because you try to create database migration file with exactly same name as we have before. To find out which file you created, run

    Code:
    git status
    git diff
    Remove the file in app/database/migrations


    That is not in GIT (that is the one you created).

    No, don't remove then. They are the database structure needed for application.

    When you run

    Code:
    php artisan migrate
    The command will look in that folder and read files one by one sorted by date and create database tables as required.

    Now the problem is, you added one extra file here, that is not needed. To find which one you added, post result of


    Code:
    git status
    and

    Code:
    git diff
