HI all,

I have just setup the ROR environment on a vps, but once i created the
app and run rails s or db:create after modifying the database.yml it
keeps on appearing with the "Could not find gem sqlite3" etc message
which i know this as it's not install as i am using mysql. What else
have i got to do other than modifying the database.yml as to me it's
still looking for the sqlite3 to use.

Any help will be great.

Thanks!

    Did you remember to change it to mysql2 in Gemfile, and to run bundle install.

    If you did then post database.yml, Gemfile and the full error and trace.

    In which environment are you doing this (development or production) ?

    Is this VPS intended for production or development?

    What is the output you get from

    $ rake db:create

    $ rake db:migrate

    HTH,

    adapter: mysql2
    encoding: utf8
    database: development
    username: root
    password:
    pool: 5
    timeout: 5000

    # Warning: The database defined as "test" will be erased and
    # re-generated from your development database when you run "rake".
    # Do not set this db to the same as development or production.
    test:

    I would not advise to do the learning phase in development mode on a VPS
    if it is exposed to the Internet. Also, setting up all aspects of the VPS
    (including security) yourself, while learning Rails is not trivial. Maybe
    you are
    better helped by a hosting company with good service or running production
    on PaaS providers (like Heroku, Engine Yard, etc.).

    -------------------------------------------------------

    Now i can see a issue but i don't know why its happening, plus i have
    tried mysql, mysql2 still don't work

    Here is the database.yml file as well.

    -------------------------------------------------------
    # SQLite version 3.x
    # gem install sqlite3
    #
    # Ensure the SQLite 3 gem is defined in your Gemfile
    # gem 'sqlite3'
    development:
    host: localhost
    adapter: mysql2
    encoding: utf8
    database: development
    username: root
    password:
    pool: 5
    timeout: 5000

    # Warning: The database defined as "test" will be erased and
    # re-generated from your development database when you run "rake".
    # Do not set this db to the same as development or production.
    test:
    host: localhost
    adapter: mysql2
    encoding: utf8
    database: testing
    usrename: root
    password:
    pool: 5
    timeout: 5000

    production:
    host: localhost
    adapter: mysql2
    encoding: utf8
    database: production
    username: root
    password:
    pool: 5
    timeout: 5000
    Are these number of spaces exact? The .yml format
    needs an exact number of 2 spaces (no tabs) before
    the keys like 'host', 'adapter' etc. It looks like the
    number of space before the keys is not exactly 2 ?

    HTH,

    Peter

    Hi Peter,

    Its going to be both but once it's working when i have made the app in
    will go from development to production.
    I would not advise to do the learning phase in development mode on a VPS
    if it is exposed to the Internet. Also, setting up all aspects of the
    VPS
    (including security) yourself, while learning Rails is not trivial.
    Maybe
    you are
    better helped by a hosting company with good service or running
    production
    on PaaS providers (like Heroku, Engine Yard, etc.).


    the output of db:create is :

    Hi Peter,

    No the development won't to viewable to general users, but i completely
    understand your point. I do know my way around linux anyway i have
    security mind as well but it just getting to setup and i can fine tune
    everything after.

    I have got it working after getting the above messages i added the
    "require 'rake/dsl_definition'" before the require 'rake' in the rake
    file and after a few other error i got it working and as you suggested
    the space issue i sorted them and when i db:create it works great.

    p.s i did found something before finding to put the require
    'rake/dsl_definition ' that it was because the rake 9.0 broken rails,
    but this was not the case as i had a higher version than that.

    Many thanks for all the help

    Paul
