connect to PostgreSQL server: FATAL: no pg_hba.conf entry for host

Question

Hello I am trying to run a website sent to me but after doing so this error appeared

connect to PostgreSQL server: FATAL: no pg_hba.conf entry for host "4X.XXX.XX.XXX", user "userXXX", database "dbXXX", SSL off in C:\xampp\htdocs\xmastool\index.php on line 37

after Googling it it says that i just need to add an entry in the pg_hba.conf file for that particular user. this is my pg_hba.conf file.

# TYPE  DATABASE        USER            ADDRESS                 METHOD
# IPv4 local connections:
local dbXXX userXXX md5
host    dbXXX  userXXX  XX.XXX.XXX.XXX           md5
host    all             all             127.0.0.1/32            md5
# IPv6 local connections:
host    all             all             ::1/128                 md5
# Allow replication connections from localhost, by a user with the
# replication privilege.
#host    replication     postgres        127.0.0.1/32            md5
#host    replication     postgres        ::1/128                 md5

but after doing so, the error still persist. I restarted my XAMPP server several times but no changes appears. Thanks in advance

Answer 1

Add or edit the following line in your postgresql.conf :

listen_addresses = '*'

Add the following line as the first line of pg_hba.conf. It allows access to all databases for all users with an encrypted password:

# TYPE DATABASE USER CIDR-ADDRESS  METHOD
host  all  all 0.0.0.0/0 md5

Restart Postgresql after adding this with service postgresql restart or the equivalent command for your setup.

Answer 2

This solution works for IPv4 / IPv6

nano /var/lib/pgsql/data/pg_hba.conf

add at final

host all all      ::1/128      md5
host all postgres 127.0.0.1/32 md5

and then restart postgresql service

/etc/init.d/postgresql restart

Answer 3

The way I solved this was:

Added the line as below in pg_hba.conf:

hostnossl    all          all            0.0.0.0/0  trust        

and this was modified in postgresql.conf, as shown:

listen_addresses = '*'  

I had this instance running on a Centos 7.3 and Postgres 9.5 in a VM in Azure, given this was a POC (proof of concept) you won't want to connect without SSL in your actual prod environment.

To connect to the instance I was using pgAdmin 4 on macOS Sierra.

Answer 4

Fresh Postgres 9.5 install, Ubuntu.

The key was the local connection type, since psql uses domain socket connection.

pg_hba.conf

# TYPE DATABASE USER CIDR-ADDRESS  METHOD
local all all md5
host  all  all 0.0.0.0/0 md5

Answer 5

I had the same error when I tried to connect to a local database using an SSH tunnel. I solved it by changing the host name from localhost to 127.0.0.1.

Answer 6

1. Add the following line in the bottom of pg_hba.conf:

   hostnossl all all 0.0.0.0/0 md5

2. Add/modify the line in postgresql.conf:

   listen_addresses = '*'

3. MAKE SURE THAT the user that is connecting has a password: (Example connect user named postgres)

   a. Run the following psql command with the postgres user account:

   sudo -u postgres psql postgres

   b. Set the password:

   # \password postgres

Answer 7

In my case, I had to add the exact line as suggested by the error information. Cannot bypass it by adding "all" users with all IPs as rule. Now it is like:

PosgreSQL 10.5 on CentOS 7.

# IPv4 local connections:
host    all             all             127.0.0.1/32                    md5
host    <db_name>       postgres        <my_client_machine_ip>/32       md5

Answer 8

This below worked for me: (pg_hba.conf)

# TYPE  DATABASE        USER            ADDRESS                 METHOD
# "local" is for Unix domain socket connections only     
local   all             all                                     md5
# IPv4 local connections:
host    all             all             127.0.0.1/32            trust
host    all             all             0.0.0.0/0               trust
# IPv6 local connections:
host    all             all             ::1/128                 trust
host    all             all             0.0.0.0/0               trust

trust

Allow the connection unconditionally. This method allows anyone that can connect to the PostgreSQL database server to login as any PostgreSQL user they wish, without the need for a password or any other authentication.

md5

Require the client to supply a double-MD5-hashed password for authentication.

Answer 9

Instructions for Debian users.

Login as posgres user:

$ sudo su - postgres

Get the location of pg_hba.conf by quering the database:

$ psql -c "SHOW hba_file;"

              hba_file               
-------------------------------------
/etc/postgresql/11/main/pg_hba.conf
(1 row)

Open pg_hba.conf:

nano /etc/postgresql/11/main/pg_hba.conf

Add configuration where it says "Put your actual configuration here":

# TYPE DATABASE USER CIDR-ADDRESS  METHOD
host  all  all 0.0.0.0/0 md5

Logout to your user:

$ exit
logout

Restart your postgres server for changes to take effect:

$ sudo systemctl restart postgresql

Answer 10

It works for me only adding the below configuration:

# IPv4 local connections:
host    all             all             127.0.0.1/32            md5
host    all             all             0.0.0.0/0               md5
# IPv6 local connections:
host    all             all             ::1/128                 md5
host    all             all             0.0.0.0/0               md5

Answer 11

Just write the following sequence in the configuration file:

const 
  pg                = require('pg'),
config          = require('./db-config'),
    dbOption    = {
      host    : ,
      port    : ,
      user    : ,
      password  :,
      database  : 
    },

  pool          = new pg.Pool(dbOption)
  pg.defaults.ssl = true;

This is all. The file db-config contains the specification data of the host, user, password and database. With this small change it works perfectly both locally and in a pass service (Heroku). Fully tested.
