I encountered troubles when trying to connect to postgresql database within Zend framework application. In my application.ini I use
resources.db.adapter = PDO_PGSQL
resources.db.params.host = localhost
resources.db.params.username = root
resources.db.params.password = testtest
resources.db.params.dbname = testdb
But when I run the application, I got an error message
Message: SQLSTATE[08006] [7] could not create socket: Address family not supported by protocol.
Could you please tell me what can be wrong?
Zend version 1.12.3., PostgreSQL version 9.0.7, PHP version 5.3.5.
Thanks, Marek .
localhost on your machine is (most likely) resolving to the IPv6 address of localhost (::1), but since the protocol/module used does not support IPv6 connections, your connection fails.
You could either;
Use 127.0.0.1 as a host instead, that will force a connection to the IPv4 localhost.
Remove the host line completely, that will force a connection via UNIX sockets.
I had similar problem:
PDOException: SQLSTATE[08006] [7] 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
lock_may_be_available() (line of /app/ctr/ctr
web/drupal/includes/lock.inc).
The problem was caused because of a full disk. and PostgreSQL DB blocked/froze.
Making some free space and restarting of PostgreSQL DB resolved my problem.

I am learning Symfony,
I create my project with : symfony new myproject --full
directly after this I run symfony serve
in the console I am getting thoses errors :

After this the Symfony's default page is loading correctly but when I add a route to the url for example : https://127.0.0.1:8000/testtt
I'm getting this error :
An exception occurred in driver: SQLSTATE[08006] [7] could not connect to server: Connection refused
Is the server running on host "127.0.0.1" and accepting
TCP/IP connections on port 5432?
(it should be something like 'this route doesnt exist' no ?)
Please tell me how I can give you more info about my problem !
Thanks a lot !
This question pops up often enough that I think an answer is appropriate until the issue is resolved.
Assume you just created a new Symfony website-skeleton app, added a new controller and started the development server. You navigate to your new route and exceptions are tossed. Either get a 'driver not found' or a 'could connect to server'. Which of course is a bit unexpected since you have not yet done anything with the database.
The problem is that the Doctrine migrations bundle provides a data collector for Symfony's profiler bar that shows up at the bottom of the browser page when running in development mode. The data collector needs to connect to the database in order to collect migrations data. It does not care about the fact that there is no database. It just tries to connect and ends up tossing an exception.
I opened an issue on this. I am still not entirely sure if this is a feature or bug. Feel free to comment on the issue if you like.
This is a fairly recent problem though I have not tracked exactly when it first popped up. Hence many existing tutorials and step by step guides do not mention it. Consider it to be part of your development experience. Learning how to read exceptions is quite important.
There are several solutions. If you plan on using a database then go ahead and create yourself a database and adjust the DATABASE_URL to point to it. The database can be empty. The migration data collector just needs to be able to connect to it. On my local development machine I actually created a database called db_name just to avoid this error message.
A second solution is to just remove the migrations bundle with
composer remove doctrine/doctrine-migrations-bundle
And the problem goes away. If later on you need migrations then just use composer require to re-install it.
I have another solution that solves the problem without having to remove the package with composer remove ....
comment out Doctrine\Bundle\MigrationsBundle\DoctrineMigrationsBundle::class => ['all' => true], in /config/bundles.php
Then move /config/packages/doctrine_migrations.yaml up one directory so it's not longer trying to be included.
This may be a little less intimidating for new developers.
If the issue appears when you want to access the localhost.../lucky/number, go to .env file under the your "folder name" and uncomment this line:
DATABASE_URL="sqlite:///%kernel.project_dir%/var/data.db"
And the rest of them with mySQl and Postgres, comment them.
Hope it works for you. :)
I run Windows and I am trying to install postgres, but I can't get it to work. During installation, I get the error:
Failed to load sql modules into the database cluster
When I try to access the server in pgadmin or via SQL Shell, I get the error:
could not connect to server: Connection refused (0x0000274D/10061) Is the server running on host "localhost" (::1) and accepting TCP/IP connections on port 5432? could not connect to server: Connection refused (0x0000274D/10061) Is the server running on host "localhost" (127.0.0.1) and accepting TCP/IP connections on port 5432?"
I have found a log in the data-folder saying:

Can someone please help me?
I had the same issue and followed different tips and tricks available on the internet but nothing worked.
I fixed that issue by following these steps:
First disable antivirus for an hour
Create a folder in either C drive or D drive and give full permission to User
Then again install a fresh application. If you have already installed then uninstall that and install from starting.
Make sure to choose that folder only at the time of installation
I'm trying to connect to postgres database in heroku using heroku pg:psql postgresql-rigid-33416 --app murmuring-ocean-62645, however I got this message

psql: could not connect to server: Connection timed out (0x0000274C/10060)

I have tried to turn off my firewall but the problem persists. Any idea how to solve this?

In case someone else has this issue. I had same problem. I had to lower my network security by changing my Firewall Level on my local compter to 'Low' and it works.
I am currently setting up a postreSQL server on my Windows computer.(i have 32 bit and 64 bit postgresql)
when I use the (32bits,port is 5433) python to add some data to the database, it gets the following error:
File "C:\Python27\lib\site-packages\psycopg2\__init__.py", line 164, in connection
conn = _connect(dsn, connection_factory=connection_factory, async=async)
perationalError: could not connect to server: Connection refused (0x0000274D/10

Is the server running on host "localhost" (::1) and accepting

Is the server running on host "localhost" (127.0.0.1) and accepting

I do write this before adding data to the database
conn=psycopg2.connect("dbname='your_database',user='user', password='password','host'='127.0.0.1','port'='5433')
but it doesn't work~~
thanks!!
You are mixing up your connect() arguments. The "dbname" signals you are using a libpq url, so a single string argument.
http://initd.org/psycopg/docs/module.html
Try fixing that and see if it does the job.
When I type localhost on my browser , I am unable to successfully connect..I am getting
The socket connection to localhost failed.
ErrorCode: 10061.
No connection could be made because the target machine actively refused it 127.0.0.1:80
How can I fix it?
You start a web server on your localhost listening on port 80. At present there isn't one.
