Connection Refused Error In Postgresql

most common error messages you may encounter. While the error messages do in fact tell you exactly what is causing the problem, I find that users often don't know what next steps to take in resolving the postgresql connection refused is the server running on host issue. If you there is a common error you would like me to include in postgresql 5432 connection refused this list or you find anything inaccurate on this page, please drop me an E-mail at info@revsys.com.

When you simply run psql from the command line it, by default, attempts to log you into a database with the same

name as your current Unix user name. In this case that is 'root', but it could be 'postgres', or 'bob'. If you are setting up your database for the first time, you will need to become the PostgreSQL user ( typically 'postgres' ) which can be accomplished by either: logging in as that user su'ing to root and as root su'ing to the postgres user Once you are the postgres user you will need to setup one or more databases and some users.

Common Cause: The postmaster or PostgreSQL's server daemon process is not running. Typically this error means PostgreSQL is not currently running on the system you are logged into. You will need to start the daemon, which is typically done through your distribution's init system. The easiest way to determine if PostgreSQL is running is to look for it using ps. For example when I

First make sure PostgreSQL server has been started to remote server.# /etc/init.d/postgresql startIf it is running postgres connection refused and you get above error, you need to add enable TCP/IP support. By default, the PostgreSQL server only allows connections to the database from the local machine or localhost. This is a security feature.Step # 1: http://www.revsys.com/writings/postgresql/errors.html 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 would like to give access to 192.168.1.0/24 network: host all all 192.168.1.0 255.255.255.0 trust Please 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 http://www.cyberciti.biz/faq/postgresql-remote-access-or-connection/ 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.conf Now 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 sales Where,-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. You must have account and permission to connect as vivek user.-d sales : Specifies the name of the database (sales) to connect to.See also:=> How do I add a user to PostgreSQL database server?

9.0.23 Documentation Prev Up Chapter 17. Server Setup and Operation Next 17.3. Starting the Database Server Before anyone can access the database, you must start the database server. The database server program is called postgres. https://www.postgresql.org/docs/9.0/static/server-start.html The postgres program must know where to find the data it is supposed to use. This is done with the -D option. Thus, the simplest way to start the server is: $ postgres -D /usr/local/pgsql/data which will leave the server running in the foreground. This must be done while logged into the PostgreSQL user account. Without -D, the server will try to use the data directory named by the environment variable PGDATA. If that variable is connection refused not provided either, it will fail. Normally it is better to start postgres in the background. For this, use the usual Unix shell syntax: $ postgres -D /usr/local/pgsql/data >logfile 2>&1 & It is important to store the server's stdout and stderr output somewhere, as shown above. It will help for auditing purposes and to diagnose problems. (See Section 23.3 for a more thorough discussion of log file handling.) The postgres program also takes a number of other postgresql connection refused command-line options. For more information, see the postgres reference page and Chapter 18 below. This shell syntax can get tedious quickly. Therefore the wrapper program pg_ctl is provided to simplify some tasks. For example: pg_ctl start -l logfile will start the server in the background and put the output into the named log file. The -D option has the same meaning here as for postgres. pg_ctl is also capable of stopping the server. Normally, you will want to start the database server when the computer boots. Autostart scripts are operating-system-specific. There are a few distributed with PostgreSQL in the contrib/start-scripts directory. Installing one will require root privileges. Different systems have different conventions for starting up daemons at boot time. Many systems have a file /etc/rc.local or /etc/rc.d/rc.local. Others use rc.d directories. Whatever you do, the server must be run by the PostgreSQL user account and not by root or any other user. Therefore you probably should form your commands using su postgres -c '...'. For example: su postgres -c 'pg_ctl start -D /usr/local/pgsql/data -l serverlog' Here are a few more operating-system-specific suggestions. (In each case be sure to use the proper installation directory and user name where we show generic values.) For FreeBSD, look at the file contrib/start-scripts/freebsd in the PostgreSQL source distribution. On OpenBSD, add the following lines to the file /etc/rc.local: if [ -x /usr/local/pgsql
