Databases and libraries

• Postgres

Minimally alter one of Postgres's configuration files to accept (app-specific) connections from Rails...:

nano /etc/postgresql/9.1/main/pg_hba.conf

by changing 'peer' to 'md5' where it says:

  # "local" is for Unix domain socket connections only
  #local   all         all                               peer
  local   all         all                               md5

Restart the Postgres server:

sudo /etc/init.d/postgresql stop
sudo /etc/init.d/postgresql start

sudo apt-get install postgresql libpq-dev
sudo -u postgres createuser --echo --encrypted --pwprompt --no-superuser --no-inherit --createdb --no-createrole <app_user_name>

• MySQL

sudo apt-get install mysql-server mysql-client libmysqlclient-dev

• Sqlite3

sudo apt-get install sqlite3 libsqlite3-dev
