Openshift RoR. Cant connect to db through mysql.sock - mysql

Question

I have Openshift RoR app. When I trying to run some rake task which uses DB, it gives me error:
rake aborted!
Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)
When I pushed my app 1st time there was no socket value in database.yml, I added it later trying to fix this issue, set it to env variable of socket, which is:
"/var/lib/openshift/some_key/mysql//socket/mysql.sock
" In mysql.log I have this same socket too. So I don't understand where is this "/var/lib/mysql/mysql.sock" came from. I guess I need rebuild my app somehow, but it only restarts on "push" now. Or is this wrong idea?
EDIT: Here is my database.yml from .openshift/config. As i mentioned i added "soket: <%=ENV['OPENSHIFT_MYSQL_DB_SOCKET']%>" later, after first push. I just tried 'force_clean_build' marker, it didn't help though.
development:
adapter: mysql2
database: database
username: root
password: psswd
host: localhost
test:
adapter: mysql2
database: database
username: root
password: psswd
host: localhost
production:
adapter: mysql2
database: "<%=ENV['OPENSHIFT_APP_NAME']%>"
username: "<%=ENV['OPENSHIFT_MYSQL_DB_USERNAME']%>"
password: "<%=ENV['OPENSHIFT_MYSQL_DB_PASSWORD']%>"
host: <%=ENV['OPENSHIFT_MYSQL_DB_HOST']%>
port: <%=ENV['OPENSHIFT_MYSQL_DB_PORT']%>
soket: <%=ENV['OPENSHIFT_MYSQL_DB_SOCKET']%>

Turned out server didn't run all necessary rake:db tasks on deploy. That's why I was getting 'We are sorry...' error. And to run rake tasks through ssh, You need to add "RAILS_ENV=production" before it, like this:
RAILS_ENV=production rake db:setup
This 2 problems (not necessarily connected) made it look for me, like there is problem with DB config.
