I want to try get Rails and MSSQL talking within our CI tool, CircleCI. I work on a mac, so setting this up was fairly pain free. I installed FreeTDS locally using Homebrew. Then I spawned up a MSSQL docker image and set my config in my rails app to point to it and that all worked.
CircleCI is a little different.
I have done the following.
In my gemfile added:
# mssql database gems
gem 'tiny_tds'
gem 'activerecord-sqlserver-adapter'
Modified our database.yml file with:
default: &default
adapter: sqlserver
pool: 5
encoding: utf8
mode: dblib
development:
<<: *default
host: localhost
database: collections_development
username: sa
password: P#55w0rd
test:
<<: *default
host: localhost
database: collections_test
username: sa
password: P#55w0rd
I built a docker image with:
FROM circleci/ruby:2.4.1-node-browsers
RUN set -ex \
&& sudo apt-get install build-essential \
&& sudo apt-get install libc6-dev \
&& sudo wget -O freetds-1.00.54.tar.gz "ftp://ftp.freetds.org/pub/freetds/stable/freetds-1.00.54.tar.gz" \
&& sudo tar -xzvf freetds-1.00.54.tar.gz \
&& cd freetds-1.00.54 \
&& sudo ./configure \
&& sudo make \
&& sudo make install
This image is hosted on docker hub here.
Next I built the CircleCI config:
version: 2
jobs:
build:
working_directory: ~/collections-api
docker:
- image: legendaryrob/ruby:2.4.1-node-browser-freetds54-lib6c
environment:
RAILS_ENV: test
- image: microsoft/mssql-server-linux
environment:
ACCEPT_EULA: Y
SA_PASSWORD: P#55w0rd
environment:
RAILS_ENV: test
steps:
- checkout
- restore_cache:
name: Restore bundle cache
keys:
- collections-api-bundle-{{ checksum "Gemfile.lock" }}
- run:
name: Allow CI to read from pdg gemserver
command: bundle config https://gems.pdg.io/ $GEMS_USERNAME:$GEMS_PASSWORD
- run:
name: Bundle Install
command: bundle install --path vendor/bundle --jobs 4 --retry 3
- save_cache:
name: Store bundle cache
key: collections-api-bundle-{{ checksum "Gemfile.lock" }}
paths:
- vendor/bundle
- run:
name: Wait for DB
command: dockerize -wait tcp://localhost:1433 -timeout 1m
- run:
name: test tds connection
command: tsql -C
# Run setup
- run: ./spec/setup/circle_setup.sh
- run:
name: Create the database
command: bundle exec rake -v --trace db:create
- run:
name: Migrate the database
command: bundle exec rake -v --trace db:migrate
- run:
name: Check environment variables are present
command: bundle exec rake env_variables:check
- run:
name: Run tests
command: bundle exec rspec
The MSSQL docker image I am getting from Microsoft's docker hub account directly -> https://hub.docker.com/r/microsoft/mssql-server-linux/
Here you can see a couple things. I set ruby box I built with TDS installed and all the dependancies needed. I ensured that we are using the same version of TDS that we are using locally, because it is working locally, I have also tried a few of the other versions just incase I was dealing with a flakey version.
I also ensure that we can connect to the MSSQL docker box and ensure that we have the right tds config:
- run:
name: Wait for DB
command: dockerize -wait tcp://localhost:1433 -timeout 1m
- run:
name: test tds connection
command: tsql -C
This will result in the following:
#!/bin/bash -eo pipefail
dockerize -wait tcp://localhost:1433 -timeout 1m

But then I get timeouts. These timeouts are intermittent, they will sometimes occur when we are trying to connect to localhost:1433
But mostly it occurs when we get to the rake tasks.
Below is the stack trace I am getting, I have tried a few different versions of MSSQL docker as well with no effect. If anyone has tried doing this please let me know I would really appreciate some help around doing this.

Tasks: TOP => db:create

Note: The reason we are needing to connect to MSSQL is because we are going to be writing to the db for a short time, we have another team who relies on Access that is using MSSQL. I am just hoping there is someone else out there who has fought this beast and won.

Tasks: TOP => db:migrate
(See full trace by running task with --trace)
I checked out some other threads with other people who had the same problem however their solutions did not really have any luck for me.
I tried uninstalling and reinstalling PG as well as getting rid of the .PID file however it doesn't look like I seem to have one.
Any clues, pointers or advice? Thanks in advance.
This means either your database.yml file in config/ directory is not set up correctly for your environment, most likely development as it is the default or you do not have postgresql running.
If you do not have postgresql running either install it or start it up. You can check postgresql, more than likely with either:
sudo service postgresql status
or
ps -ef | grep postgres
If you do have postgresql running, then check your database.yml file and edit it appropriately, most likely something like:
development:
adapter: postgresql
encoding: unicode
database: database_name
host: localhost
username: user_name
password: password
When I run rake:db migrate from my rails app, I get this output:
rake aborted!
PG::ConnectionBad: could not connect to server: Connection refused
Is the server running on host "localhost" (127.0.0.1) and accepting
TCP/IP connections on port 5432?

In my gemfile I have
gem 'pg'
and in my database.yml I have
default: &default
adapter: postgresql
encoding: unicode
pool: 5
development:
<<: *default
database: fake_lunch_hub_development
test:
<<: *default
database: fake_lunch_hub_test
production:
<<: *default
database: fake_lunch_hub_production
username: fake_lunch_hub
password: <%= ENV['FAKE_LUNCH_HUB_DATABASE_PASSWORD'] %>
This setup used to connect to the database perfectly, but I did a lot of refactoring and renaming (the project is no longer called fake_lunch_hub) and I moved the project off of my local machine (mac) and onto an amazon EC2 instance (ubuntu).
There are many other questions on Stackoverflow that offer solutions using psql, but when I run the command
psql
I get this:
The program 'psql' can be found in the following packages:
* postgresql-client-common
* postgres-xc-client
Try: sudo apt-get install <selected package>
I'd rather not download a new postgres package because I already have it successfully downloaded from the gem.
How can I get that server started and accepting connections?
EDIT:
FULL SOLUTION:
sudo apt-get install postgres
sudo su
su postgres
createuser ubuntu
createuser fake_lunch_hub
createdb fake_lunch_hub
exit
exit
rails server
resolves the issues
The gem is just a way for Ruby/Rails to talk to a Postgres server. The gem itself does not contain its own server.
You'll still need to install one:
sudo apt-get install postgresql

Tasks: TOP => db:structure:dump
If I run it like this in CMD, it works:
cd C:\Program Files (x86)\PostgreSQL\9.1\bin
pg_dump.exe -i -s -x -O -f C:/Sites/care/db/structure.sql care_development
I have tried changing the permission on both the pg_dump.exe folder/file and the rails folder/files. But doesn't seem to make any different. Tried adding full permissions for Users, System and even Everyone.
I also tried adding --username params to the pg_dump call (in the rake code) and adding Login Roles that match my windows user in pgAdminIII.
(I'm on Windows 7, Rails 3 and postgreSQL 9)
Do anyone know what the problem can be?
I have same problem on my Linux machine:
Then i used the following command to make it run:
su
>> I logged in first with my Admin user
su -postgres
I save my .sql file in my /tmp folder
For dumping the .sql file in database i run the command
psql -u postgres -d my_db_name -a -f /tmp/path_to_sql_file
It works greatly for me. Hope it may help you.
I'm trying to run rake db:create or rake db:setup but I get the following error. It's strange because rake db:create it's working fine from others folders with other Rails projects.
user:project user$ rake db:create
could not connect to server: No such file or directory
Is the server running locally and accepting
connections on Unix domain socket "/var/pgsql_socket/.s.PGSQL.5432"?

Couldn't create database for {"adapter"=>"postgresql", "database"=>"project_test", "username"=>nil, "password"=>nil, "min_messages"=>"warning"}

Posgree is insatelled on /usr/local/var/postgres. Shouldn't rake try to look it in the same folder instead of /var/pgsql_socket/ ? (I don't have a /usr/local/var/pgsql_socket anyways)
Solved!
Solution was simple to update current installed gems.
Another solution to try is set host: localhost or whatever host you use on development settings on database.yml file.
I installed PG on Mac OS X via Homebrew (I didn't realize it came default in Mac OS X), and had the same problem. I may have made the problem worse by installing the pg gem before installing pg via Homebrew.
I solved this same problem by doing the following:
Make sure that all binaries are pointing to binaries in Cellar directory (/usr/local/Cellar on Mac OS X)
Uninstall pg gem gem uninstall pg
Reinstall with Homebrew configs gem install pg -- --with-pg-config=/usr/local/bin/pg_config (if you created a rails project with pg setup, this is explained in your database.yml config file)
And it worked!
First, you will need to create your user manually in Postgres, while granting privilege of database creation (AKA createdb) for this user.
To do so, first, open Postgres shell prompt
$ sudo -u postgres psql
Create your user
postgres=# create role Your_DB_username with createdb login password 'YOUR_PASSWORD';
Exit from Postgres shell
postgres=# \q
Do whatever db-related rake task:
$ rake db:create
And it will work!
The answer from zquintana above worked for me with a few small caveats.
My solution (using Homebrew):
If you have the gem installed gem uninstall pg
Remove old copy of postgresql brew uninstall postgresql
Re-install postgresql brew install postgresql
The install notes mention:
To have launchd start postgresql at login:
ln -sfv /usr/local/opt/postgresql/*.plist ~/Library/LaunchAgents
Then to load postgresql now:
launchctl load ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist
Or, if you don't want/need launchctl, you can just run:
postgres -D /usr/local/var/postgres
So run ln -sfv /usr/local/opt/postgresql/*.plist ~/Library/LaunchAgents
Then launchctl load ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist
Now re-install the gem with the Homebrew configs gem install pg -- --with-pg-config=/usr/local/bin/pg_config
Now run your rake db:create
In my case this was all I needed: https://dba.stackexchange.com/a/75221
pg_ctl -D /usr/local/var/postgres -l /usr/local/var/postgres/server.log start
I encountered an identical issue and was able to solve the error by:
using postgresapp.com (recommended by heroku in https://devcenter.heroku.com/articles/heroku-postgresql#local-setup),
adding to config/database.yml
host: localhost
resetting shared memory settings as recommended in troubleshooting section of http://postgresapp.com/documentation:
sudo sysctl -w kern.sysv.shmall=65536
sudo sysctl -w kern.sysv.shmmax=16777216
Also check you don't have an open connection such as a client or an application connected to the instance. If that happen you will see this in the error
Couldn't create database for {"adapter"=>"xxxx", "database"=>"xxxx", "host"=>"localhost", "username"=>"postgres", "password"=>"xxxxx", "pool"=>5, "timeout"=>5000}
rake aborted!
ActiveRecord::StatementInvalid: PG::ObjectInUse: ERROR: source database "template1" is being accessed by other users

Simple add host: localhost to your database.yml
For more detail please visit rake db:create:all fails to connect to PostgreSQL database
I was able to solve this by making sure that the name of my database in the database.yml file was in the following format: appname_development, appname_test, and appname_production. Here is my database.yml file as an example:
development:
adapter: postgresql
database: parallax_development
username:
password:
test:
adapter: postgresql
database: parallax_test
username:
password:
production:
adapter: postgresql
database: parallax_production
username:
password:
