Psql Could Not Connect To Server Connection Refused Ubuntu
the PostgreSQL server only allows connections to the database from the local machine or localhost. This is a security feature.Step # 1: Allow remote IP address to access PostgreSQLYou need to open file called /var/lib/pgsql/data/pg_hba.conf. Login as postgres user using su command:$ su - postgres
$ vi /var/lib/pgsql/data/pg_hba.conf
Now append following line. Let us say you psql: could not connect to server: no such file or directory ubuntu would like to give access to 192.168.1.0/24 network:host all all 192.168.1.0 255.255.255.0 trustPlease replace 192.168.1.0 and 255.255.255.0 to reflect the actual network IP address range of the clients system in your own network.Save close the file.Step # 2: Allow communication over TCP/IPYou need to open PostgreSQL configuration file /var/lib/pgsql/data/postgresql.conf$ vi /var/lib/pgsql/data/postgresql.confNow bind and open TCP/IP port by setting tcpip_socket to true:tcpip_socket = trueSave and close the file.Step # 3: Restart PostgreSQL serverRestart the PostgreSQL server with the following command# /etc/init.d/postgresql restartThis will open default port 5432.Step # 4: Test your setupUse psql command from client system as follows:psql -h PostgreSQL-IP-ADDRESS -U USERNAME -d DATABASENAMEConnect to remote server by IP address 192.168.1.5 and login using vivek user to connect to sales database, use:$ psql -h 192.168.1.5 -U vivek -d salesWhere,-h 192.168.1.5 : Specifies the host name of the machine or IP address (192.168.1.5) on which the server is running.-U vivek : Connect to the database as the vivek username instead of the default.

Before I added the pg_hba.conf entry with the client's IP address, I was getting an error message : xdev@xdevbox:~$ psql -U postgres testdb -h 10.1.1.47 psql: FATAL: no pg_hba.conf entry for host "10.201.50.71", user "postgres", database could not connect "testdb", SSL off I added the client's IP with trust settings. I also changed the listen address in postgres.conf on the server to listen to "*". Then I restarted the database server using /etc/init.d/postgresql restart command. Now when I try to connect, I get the following error message: psql: could not connect to server: Connection refused Is the server running on host "10.1.1.47" and accepting TCP/IP connections on port 5432? in postgresql.conf, the port is set to 5432. I'm not sure what else to check.

Check the PostgreSQL log files for the reason why - probably a typo in pg_hba.conf. –Craig Ringer May 5 '15 at 5:03 I had to change the listen address from * to the specific ip address. –dot May 5 '15 at 13:29 add a comment| 1 Answer 1 active oldest votes up vote 2 down vote accepted You have to configure the following two files pg_hba.conf host all all 0.0.0.0/0 md5 postgresql.conf listen_addresses='*' You have to check if the port 5432 is open: http://www.yougetsignal.com/tools/ope
