I`m using postgresql database on my web server (ubuntu + nginx) and it works with backend app. I want to connect remotely using pgAdmin
but it always throw this error:
could not connect to server: Connection timed out(0x0000274C/10060)
Is the server running on host "ip" and accepting
TCP/IP connections on port 5432?
I already add to my pg_hba.conf this line:
host all all all password
and also add to postgresql.conf line:
listen_addresses = '*'
netstat -nlt does next result, and it`s enough in tutuorials i found, but still cant access my database
Found a solution, it works as well after this command:
sudo ufw allow 5432/tcp
Open file named pg_hba.conf
sudo vi pg_hba.conf
and add this line to that file
host all all 0.0.0.0/0 md5
It allows access to all databases for all users with an encrypted password
restart your server
sudo /etc/init.d/postgresql restart

I am trying to install Postgres as a backend DB instead of Sqllite. I followed these steps but ran into an error. can someone help, please?
Steps followed:
activated virtual env.
installed postgreSQL
sudo apt-get install postgresql postgresql-contrib
created psql object with:
sudo -u postgres psql
4.create the user and database for the airflow
CREATE USER **** PASSWORD '****';
postgres=# CREATE DATABASE airflow;
postgres=# GRANT ALL PRIVILEGES ON ALL TABLES IN SCHEMA public TO newt;
updated postgresql.conf with listen_addresses= '*'
added pg_hba.conf with
host db-name user-name ip-address trust
updated airflow.cfg file with
sql_alchemy_conn = postgresql+psycopg2://user-name:password#localhost:5432/db-name
restarted airflow db.
airflow resetdb
After the 8th steps I got below error, what am i doing wrong here? any advise
Error message
sqlalchemy.exc.OperationalError: (psycopg2.OperationalError) could not connect to server: Connection refused
Is the server running on host "localhost" (::1) and accepting

After changing the pg_hba.conf and postgresql.conf you have to tell PostreSQL that a change has been made. You can do it by either restarting the database, e.g. on Ubuntu
$ sudo service postgresql restart
... or by executing the function pg_reload_conf
SELECT pg_reload_conf():
In case client and database are in different machines, make sure that there is no firewall between them messing things up.
Unrelated note: Also keep in mind that setting a connection to trust in the pg_hba.conf means that no password is required. For testing purposes more than legit but quite dangerous if forgotten in production ;)
I am trying to connect to a VM ubuntu from my local computer. On the VM I have created a postgresql database. Then I followed all steps that I could find on several tutorial when it comes to allow access for remote connexion to the db:
add host all all 0.0.0.0/0 trust to the pg_hba.conf file
add listen_addresses = '*' to the postgresql.conf file
remove the firewall by executing sudo ufw allow 5432/tcp
restart postresql by executing sudo systemctl restart postgresql
By using the command psql and then \c gives You are now connected to database "postgres" as user "postgres".
I then create a password by executing ALTER USER postgres WITH PASSWORD 'password';
Then I use postico to connect locally. I want to connect with this same default superuser postgres for testing. I use the VM ip address as host, db name is postgres user postgres, password is password and port 5432 as mentioned above.
After trying to connect for a while with the message opening connection to server, the result is:
could not connect to server: Operation timed out
Is the server running on host "***.**.**.***" and accepting
TCP/IP connections on port 5432?
Any help please? I did all steps I could find on many tutorials but still failing to connect.
I missed a bit with chmod and permissions.
And now got a lot of problems with access to folders.
If I start server I see in browser:
could not connect to server: Connection refused Is the server running
on host "localhost" (::1) and accepting TCP/IP connections on port
5432?
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?
command
service --status-all
tells that postgres works
[ + ] postgresq works
Next I changed next files
sudo nano /etc/postgresql/9.5/main/postgresql.conf
#listen_addresses = 'localhost'
to
listen_addresses = 'localhost, server_ip, *'
sudo nano /etc/postgresql/9.5/main/pg_hba.conf
add
host all all server_ip/24 trust
then command
psql -U postgres -h server_ip
and error
psql: could not connect to server: Connection refused
Is the server running on host "95.213.200.26" and accepting
TCP/IP connections on port 5432?
The following chain of actions leads to a slightly different error
command
which psql
answer
/usr/bin/psql
sudo su - postgres
No directory, logging in with HOME=/
psql
psql: could not connect to server: Permission denied
Is the server running locally and accepting
connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?
Wich file permissions do I have to change here?
Check that unix_socket_directories on the server is set to the same directory (/var/run/postgresql) as the default socket directory that was configured when the client was compiled (this requires a server restart).
Alternatively, you can use the --host option of psql or set the PGHOST environment variable to tell the client to look for the socket file in /tmp, where the server creates it.
It looks like client and server are from different installations, otherwise the configured default should be the same for both. Or you have a bad PGHOST environment variable set by accident.
Check listen addres syntax. Use:
listen_addresses = '*'
For the server to listen on both localhost and the server ip.
This question is really hard. I made a great mistake with permissions 777 for / folder and whole system broke. So it is really easier delete server and start new project.
I have installed PostgreSQL. However everytime I try to connect through PGAdmin or through psql it gives me the below 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 checked the postgresql.conf file and the line: listen_addresses = '*' isn't commented out.
Also this is how my pg_hba.conf file is set:
# IPv4 local connections:
host all all 127.0.0.1/32 trust
# IPv6 local connections:
host all all ::1/128 trust
Can anyone please advise on how I can resolve this issue?
Thanks!
Use services "start -> run -> services.msc" and look for the postgresql-[vers] service.
If it is not running try to start it, if it won't start open the event-viewer (start -> run -> eventvwr) and look for error messages relating to the PostgreSQL service.
In my case it was postgres.config. The port was somehow changed to 5433 in there and I do not remember doing it myself lol. So make sure your ports are matching up in your project vs postgres.config
pg_hba.conf.txt has to be called pg_hba.conf.
Beyond this, when you have en authentication error you will get a message similar to:
psql -U nonexistent
psql: FATAL: Peer authentication failed for user "nonexistent"
The error you are getting means most likely that PostgreSQL is not started on this server.
You can start PostgreSQL with:
service postgresql start
service postgresql status
This worked for me -
In C:\Program Files\PostgreSQL\data\postgresql.conf set listen_addresses ='localhost'
Then try -
pg_ctl -D "C:\Program Files\PostgreSQL\9.5\data" start
if already try restarting using pg_ctl
It works for me.
Remember, whatever comes after -D should be the path to where you installed PostgreSQL, to the data folder, which holds the pg_hba.conf and postgresql.conf files.
pg_ctl start -D "C:/Program Files/PostgreSQL/9.6/data"
Maybe you can try this.
Open cmd and insert.
"C:\Program Files\PostgreSQL\11\bin\pg_ctl.exe" runservice -N "postgresql-x64-11" -D "C:\Program Files\PostgreSQL\11\data" -w
Hit enter...
I successfully installed postgres through homebrew, and i set it run automatically by doing
launchctl load ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist
So, right now i can access to psql from my terminal (i use iterm2 + oh my zsh)
psql (9.6.1)
Type "help" for help.

The problem is, postgres management tools like postico, pgadmin cannot access to it
for postico, error message is
could not connect to server: Connection refused
Is the server running on host "localhost" (::1) and accepting
TCP/IP connections on port 5435?
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 5435?
which is weird because from my understanding, accessing to the database from terminal and management tools are basically the same if configured correctly
My pg_hba.conf and postgresql.conf are set as default (didn't make any changes there), but i tried doing
listen_addresses = 'localhost'
=>
listen_addresses = '*'
(restart server)
still didn't work
Please help!
Port 5435 is not standard for PostgreSQL. Are you sure PG is running on it? If you didn't change it in postgresql.conf it must be 5432. Please check it.
must check pg_hba.conf. If there doesn't have much restriction, you can put to end of this file by below line:
host all all all trust
After that, reload/restart instance.
Check if your PC is using firewall. If yes, please turn off it.
