Prerequsities

This article assumes that you already have running a PostgreSQL server on your system. If not, use one of the below links to install the PostgreSQL database server on your system.

Find Configuration File

In order to install PostgreSQL on our system we need to update our repository and for that execute the below command:

Configure PostgreSQL to Allow Remote Connections

In order to allow all the IP addresses to connect to the PostgreSQL server, we need to configure the file and make some changes, for that you have located the configuration file in the previous step.

Conclusion

PostgreSQL database is default set to bond with localhost which restricts the other IP address and host to connect or have the access to the PostgreSQL server. In this article, we guided you through the configuration of PostgreSQL to allow remote connection so that other ips can bond to the server.

What is PostgreSQL?

PostgreSQL is a powerful, open-source object-relational database system that utilizes and adds to the SQL language. It offers numerous impressive capabilities to take the safe storage and scaling of complex data workloads in its stride.

How Does PostgreSQL Integrate with Plesk?

Remote access to PostgresSQL raises questions for Plesk users. Plesk is database-driven by nature so it requires a database server that can facilitate the variety of database services used by its components. For instance, some databases assist with hosting Plesk webmail.

Plesk PostgreSQL Remote Access

In lots of cases, users need to facilitate connections to databases via another developer’s software tools that are not operating on the server the database is operating on. You can set up Plesk PostgreSQL remote access in order to let remote servers and hosts look at your Plesk account’s PostgreSQL databases.

What port is used to forward PostgreSQL to a remote server?

Direct connection: You can set up a direct connection between your local computer and the remote PostgreSQL server on port 5432.

How to set up a direct connection to PostgreSQL?

To set up a direct connection between your local site and the PostgreSQL server, you must configure a client application. There are several PostgreSQL client applications available, but for all of them, you must provide the following information to establish a remote connection:

What is the port number before localhost?

The number before localhost is the port number at the local end of the tunnel. The number after localhost is the port number at the remote (server) end of the tunnel. If you are running a PostgreSQL server on your local computer, you might have to change the first 5432 to another port number (for example, to 5433) to avoid port conflicts.

1. Modify PostgreSQl.conf

PostgreSQL uses two configuration files postgresql.conf and pg_hba.conf that we need to update, to enable remote connection. Open terminal and run the following command to get the location of postgresql.conf file.

4. Test Remote connection

From your remote machine at 210.201.102.100, run the following command, to log into your PostgreSQL server (e.g IP – 144.41.14.44). Replace your_username below with your database username

Why do you Need to Open a Port

You need to open a remote port if you want to access data in the database from a client running on a different computer in the network. The same is true, if you want to use pgAdmin for or similar tools for SQL development.

Edit postgresql.conf

This file is usually located in /var/lib/pgsql/data/ on Linux or C:\PostgreSQL\data\ on Windows or similar.

Open Linux Firewall Port

Does your PostgreSQL database run on a Linux server with the firewall enabled (like the [ [https://sourceforge.net/projects/project-open/files/project-open/V5.0/|CentOS 7 ]project-open [ virtual appliance]])?

Open Windows Firewall Port

Does your PostgreSQL database run on a Windows server with firewall enabled?

Setting PostgreSQL Passwords

In order to set the PostgreSQL password for the user "projop" (or whatever user...) you need to connect locally to the database using an account with administration rights.

Connection Check via "psql"

Now you should be able to connect to the server using the standard PostgreSQL client "psql", the PG administration tool pgAdmin or any other application with a PostgreSQL interface. We will check with the command line "psql" tool on the remote computer:
