Unable to connect to PostgreSQL server: could not connect to server: Permission denied

Question

Warning: pg_connect(): Unable to connect to PostgreSQL server: could not connect to server: Permission denied Is the server running on host "10.0.1.201" and accepting TCP/IP connections on port 5432?

This is the error i am getting when trying to connect to remote database from linux based server

Though i am able to connect to it from localhost

Can anyone help me in this

Answer 1

One possible scenario/solution that worked for me (for the very same problem) is here:

service httpd stop
service postgresql stop

setsebool -P httpd_can_network_connect 1

service httpd start
service postgresql start

Here we're basically allowing HTTPD to connect to PostgreSQL over network by setting SELinux bool equals to 1 (true).

Answer 2

Check the listen_addresses setting in postgresql.conf . If it is set to localhost , then only loopback connections will be accepted, and remote connections will get a "connection refused" error. Set listen_addresses to "*" to enable listening on all interfaces.

Answer 3

In PostgreSQL you have to configure client authentication in pg_hba.conf on the remote server.

Read more about pg_hba.conf @ http://developer.postgresql.org/pgdocs/postgres/auth-pg-hba-conf.html , otherwise you'll never connect to that server :).

Hope it will help, Stefan
