"psycopg2.OperationalError: could not connect to server: Connection refused" error when bootstrapping
20,364
Solution 1
It looks like postgres is not running or not installed.
Try:
sudo service postgresql start
Solution 2
If the server is running and you still get the error, you must configure Postgres to accept connections from other IPs. In order to do so, locate the postgresql.conf
file.
Look for listen_addresses
property and replace localhost
with the choice of your IPs separated by comma OR *
to accept connections from any IP.
Restart the postgresql server. You should be good. :)

After the successful import of the ssh keypairs, the bootstrap generates this error.
Can anyone help me?
connection_factory=connection_factory, async=async) psycopg2.OperationalError: 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?
I have tried:
- Ensuring PostgreSQL is installed and running via: 'sudo service postgresql start`
This errors appears how i running 'sudo apt-get update'.
