New Plugin: MySQL Tasks

I wrote some convenience rake tasks to automate creation and backup of MySQL databases, and I use it all the time, so I figured I’d plugin-afy it to make it simple to use in all my projects, and share it with the world as well! Here’s the repository

MySQL Tasks

Some rake tasks to automate common database tasks (create/destroy & backup/restore).

Install

./script/plugin install http://sbecker.net/shared/plugins/mysql_tasks

Components

rake db:mysql:create           # Create database (using database.yml config)
rake db:mysql:destroy          # Destroy database (using database.yml config)
rake db:mysql:backup           # Dump schema and data to an SQL file (/db/backup_YYYY_MM_DD.sql)
rake db:mysql:restore          # Load schema and data from an SQL file (/db/restore.sql)

Specifying RAILS_ENV works if you want to perform operations on test or production databases.

Cheers for the tip. Saved me quite a bit of time from reading the mySQL docs.

Thanks mate.

This would be handy to include, too:

desc “Open shell to database (using database.yml config)” task :shell => :environment do database, user, password = retrieve_db_info mysql_shell(user, password, database) end

def mysql_shell(username, password, database) system(”/usr/bin/env mysql -u #{username} -p’#{password}’ #{database}”) end

I ran into a problem with systems that don’t have a password for the mysql “root” user. I had to change the mysql_execute method as follows:

def mysql_execute(username, password, sql)
    pwd_opt = password.nil? ? '' : "-p#{password}" 
    system("/usr/bin/env mysql -u #{username} #{pwd_opt} --execute=\"#{sql}\"")
end

This avoids the ‘password’ prompt being issued when mysql is invoked.

Jason – I’ve updated it to use your method, /usr/bin/env to properly find mysql…

Yurii – I tried your patch but for some reason it didn’t work for me. The command “env mysql 2>/dev/stdout” brings my right to the mysql prompt, so it hangs there… See if the latest version works as-is… Seems to work fine for me.

Maybe use /usr/bin/env instead for mysql_bin_root = "/usr/bin"? Heh, I’ll submit a patch.
