I followed the instructions in this post:. The answer is a combination of two answers from stackoverflow, plus modifications. The stackoverflow references are:. Bottom line: to get mysql2 working in a 64 bit environment with Ruby 2 on Windows 8. Clean up: the reason you're here is that you're probably been trying to install this gem, and it has failed, so you have some cleanup to do: gem uninstall mysql2. Run the installer and note the location of the install directory.
The instructions say that once you're done with the install, you need to run the devkitvars. You need to repeat the instructions to set the local path described in 2 above, to set the path environment variable for the local user to add the ruby dev kit bin directory, and the ruby dev kit mingw bin directory.
Next you need to install the mysql-connector. DO NOT download and run the self-installer. Instead, download the zip file and unpack it. The libmysql. You need to generate mingw64 compatible libmysql. Install the gem as follows note the use of forward slashes instead of backslashes, it will fail if you use backslashes :. Hope this helps, and hopefully someone will pay attention to the few Windows 8. I've not installed it on Windows 8, but Windows 7 needs to have this file to give mysql the dependencies requires to help it work.
You can see various tutorials on how to do this, and I'll outline a simple overview here:. Bottom line is I think your mysql2 gem isn't loading the files it requires to run, and probably doesn't show an error because it's Windows 8. I hope this will be of help when trying to install mysql2 using MariaDB on a Windows 10 machine. I had a lot of issues trying the use the connector library for some reason.
And in addition the libraries I could download were version 6 and the version of MariaDB I was using was using version 10 of the libraries.

It defines a set of methods, variables, and conventions that provide a consistent database interface, independent of the actual database being used.
DBI is independent of any database available in the backend. This is clear from the following architecture diagram. The database interface DBI layer. This layer is database independent and provides a set of common access methods that are used the same way regardless of the type of database server with which you're communicating. The database driver DBD layer. This layer is database dependent; different drivers provide access to different database engines.
Each driver interprets requests from the DBI layer and maps them onto requests appropriate for a given type of database server. Before starting this installation make sure you have the root privilege. Go in distribution directory dbi The most general configuration command looks like this, with no arguments following the config argument. This command configures the distribution to install all drivers by default.
To be more specific, provide a --with option that lists the particular parts of the distribution you want to use. If a connection is established with the data source, then a Database Handle is returned and saved into dbh for further use otherwise dbh is set to nil value and e.
Finally, before coming out it, ensure that database connection is closed and resources are released. Once a database connection is established, we are ready to create tables or records into the database tables using do method or prepare and execute method.
Statements that do not return rows can be issued by invoking the do database handle method. This method takes a statement string argument and returns a count of the number of rows affected by the statement. This will be done using the prepare method. Executing SQL query to select all the results from the database. This will be done using the execute method. If everything goes fine, then commit this operation otherwise you can rollback the complete transaction.
These two methods can be used to pass bind values to SQL statements. There may be a case when values to be entered is not given in advance. You can exit back to the command line with:. Hardware meets cloud: dedicated server with cloud integration and per-minute billing, including a personal assistant!
Scroll down to the password: line in the default section and add the root MySQL password:. Binding the server to 0. For example, if your IP address is PHP Composer is a package management system for PHP which prevents users from having to "reinvent the wheel" when it comes to commonly-used website components like user authentication or database management.
Composer is modelled on other popular package management systems like Ruby's Bundler. PHP is designed to easily integrate into a website.
This tutorial will cover connecting to a database on the same server as the PHP application, as well as how to connect to a database on a different Cloud Server. SQLite is an easy-to-configure, lightweight product which ships with Ruby on Rails by default. However, PostgreSQL is a more robust solution which provides more advanced features, scaling, and stability, which may make it more suitable for your Ruby on Rails project.
