I'm getting a random "We're sorry, but something went wrong" when I start the rails server and a IPAddr::InvalidAddressError: invalid address error in the terminal. Most of the time Ill get the error, but sometimes it will actually work for a few minutes and then show up. No idea what the issue could be.
Edit: Ok now im gettign a completely new error after restart my computer.

Seems like your Postgres Server is not running
PG::ConnectionBad (could not connect to server: Connection refused
Is the server running on host "localhost" (::1) and accepting
TCP/IP connections on port 5432?
You need to start your server and all will work well.

Hey guys i recently updated my mac to latest OS X 10.12.3
Previously my rails project was working fine, now whenever i start my rails server i keep getting this error for my project. I've tried a lot of different solution provided here in stackoverflow it simply still not working.
Here are some of it i've tried
Postgres could not connect to server
PostgreSQL error 'Could not connect to server: No such file or directory'
Thanks, please help me
PG::ConnectionBad (could not connect to server: No such file or directory
Is the server running locally and accepting
connections on Unix domain socket "/tmp/.s.PGSQL.5432"?

Try starting your postgres server using this command:
pg_ctl -D /usr/local/var/postgres -l /usr/local/var/postgres/server.log start
i found solution for this. Just download the postgres app
http://postgresapp.com/
Not sure if it will work for everyone, but it worked for me :)
My rails app connects to the database on my development machine, and in production just fine. I've cloned the project to a coworker's machine, and recreated the database locally from a pgdump. The same process works fine on my machine. But on his,
psql at the command line is having no trouble:
$ psql ROL2
psql (9.5.2)
Type "help" for help.
ROL2=#
And to test the pg gem (pg-0.18.4), I've written a simple ruby script to output our users' names:
#!/usr/bin/env ruby
require 'pg'
conn = PG.connect( dbname: 'ROL2' )
conn.exec( "SELECT * FROM users" ) do |result|
result.each do |row|
puts "#{row['first_name']} #{row['last_name']}"
end
end
No problem; works fine. But when I try connecting via the rails console or a task in the app:
$ rails db
psql: server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request.
Here's the database.yml:
# LOCAL POSTGRES
development:
adapter: postgresql
encoding: utf8
host: localhost
port: 5432
database: ROL2
pool: 5
Ditto when I try to connect with a client (Postico). I've tried with both the postgres user and his username / password.
ROL2=# \du
List of roles

Why might Rails have trouble connecting to the database, even though psql and the pg gem are working fine?
Added: the error as it appears in the Rails development logs:
PG::ConnectionBad (server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request.

Since the database.yml includes host and port, Rails is probably trying to connect to the TCP socket, whereas your connections via psql and pg (since they don't specify host or port) are using the UNIX socket. PostgreSQL comes configured out of the box to not listen to the TCP socket, so look at the postgresql.conf and ensure it has listen_addresses uncommented. If it doesn't, you can try either taking host and port out of the database.yml or modifying the config to enable TCP connections and restarting PostgreSQL.
A few days ago, I was able to successfully install Postgresql and create/migrate my databases over from SQLite (in preparation for deploying my Rails 4 app)...or so I thought.
I restarted my server, but when I try to access my app, I get this error:
PG::ConnectionBad
could not connect to server: Connection refused
Is the server running locally and accepting connections on Unix domain socket
"/var/run/postgresql/.s.PGSQL.5432"?
I've seen several similar answered questions on SO, but they all involve Macs. Since i'm using the Cloud 9 IDE instead, I thought there might be differences (for instance, the mentions of localhost are probably not relevant, because that's not how I access the app currently on c9.io.)
According to the answers on the other questions, I tried this in my terminal:
sudo ps auxw | grep post
which gave me:
ubuntu 2527 0.0 0.0 10552 888 pts/5 S+ 15:21 0:00 grep --color=auto post
then I tried:
sudo find / -name .s.PGSQL.5432 -ls
and I got:

It doesn't look like postgresql is running. Perhaps it is not set to auto start. One reason for this can be if postgresql wasn't cleanly shutdown on the last run, and leaves a pid file laying around.
Try
sudo service postgresql start
and see if it comes back, and just make sure that you shut the vm down (so the stop scripts can run) as opposed to just powering it off.
I recently installed Ruby (version: 2.0.0p598) and Rails (version: 4.1.8) on my Windows 8 computer. Everything seemed to work fine when starting up a freshly created app on rails server...
However now I want to create a rails app using postgresql as my database. I created the app with the following line of code. rails new -T -d postgresql app_name
When I start up the server and load up the browser I get PG::ConnectionBad & fe_sendauth: no password supplied
I thought this was caused by postgresql not being installed on my computer so I did so with the Windows Postgreql installer however when I try psql --version in the terminal I get 'psql' is not recognized as an internal or external command, operable program or batch file.
I thought I already installed postgresql... so why is it not recognizing it?
I've checked my gemfile and gem 'pg' is there and I bundled as well.
Also here is my logs

The server has not started. You could start it from System Preference.
System Preference -> Mysql -> Start Server.
Or else you could start it from the terminal. The command varies depending on how you installed MySQL. Try this first:
sudo /Library/StartupItems/MySQLCOM/MySQLCOM start
If that fails:
cd /usr/local/mysql
sudo ./bin/mysqld_safe
(Enter your password, if necessary)
(Press Control-Z)
bg
If that doesn't work then try below
mysql.server start
mysqladmin variables | grep socket
For me it gave,
| socket | /tmp/mysql.sock
Then add a line to your config/database.yml
development:
adapter: mysql2
host: localhost
username: root
password: xxxx
database: xxxx
socket: /tmp/mysql.sock
Hope that solves your problem.
