They assume Linux or Mac OS as the platform. I want anyone to be able to connect to postgres using a valid username, password, and IP address.īut these are not exactly what I wanted. I have no concerns whatsoever about security. But this is a development server inside a corporate firewall. In this way, other hosts can easily see the list of databases and connect to the PostgreSQL server remotely.I want my PostgreSQL instance to accept remote connections. In this article, we guided you through the configuration of PostgreSQL to allow remote connection so that other IPs can bond to the server. 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. Your PostgreSQL database server is accessible from remote hosts. Now simply open the port “5432” in the firewall and you’re all set to see all the databases and you can bond from whichever ip address to the server of PostgreSQL: sudo ufw allow 5432 Now, restart the database service to apply changes by executing the below-mentioned command: sudo systemctl restart postgresql Save the configuration file and close it. In the file you’ve to add the following lines in file: Now open the file using the command provided below: sudo nano /etc/postgresql/13/main/pg_hba.conf This file will be available under the same directory as above. In order to allow the users that we want to be connected to the database then we need to make changes in the “pg_hba.conf” file. This will allow every IP address to be connected to the database server, or if you want to specify some particular ips you can type them with spaces between each IP address. This command will open this file and in it, you need to search “listen_addresses” and add the following line.Īll you’ve to do is change the listening address from localhost to “*” or add a new line as shown above. To open the file you’ve to use the keyword “nano” or you can run the command in the terminal that is provided below: sudo nano /etc/postgresql/13/main/nf Now we need to open the file and make some changes in order to allow a remote connection. 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. Configure PostgreSQL to Allow Remote Connections Also, you need to edit “pg_hba.conf” in the same directory to allow remote access. You need to change the listening address in the nf configuration file showing in the command output. In order to install PostgreSQL on our system we need to update our repository and for that execute the below command: sudo -u postgres psql -c "SHOW config_file " If not, use one of the below links to install the PostgreSQL database server on your system. This article assumes that you already have running a PostgreSQL server on your system. In this article we’ll first go through the installation of PostgreSQL on ubuntu 20.04 then we’ll configure it to allow remote connection Prerequsities PostgreSQL is used by many large companies to save and store their data for various applications and it supports various programming interfaces as well as videos, texts, and images. With PostgreSQL users can expand the system by defining self-data types, functions, and operators. An open-source, object-based relational database PostgreSQL, provides the user with the implementation of SQL and is commonly hosted on Linux.
