Configure pgAdmin 4

NOTE: This section assumes that you have downloaded and installed pgAdmin 4.

pgAdmin is the most popular and feature-rich platform for administration and development of PostgreSQL databases. Check the pgAdmin official page for more information.

To connect to your remote PostgreSQL database server using pgAdmin 4, follow these steps:

  • Make sure that you have your cloud server’s IP address and application credentials (instructions).

  • Open port 5432 in the server firewall (instructions).

IMPORTANT: By default, the database port for the nodes in this solution cannot be accessed over a public IP address. As a result, you will only be able to connect to your database nodes from machines that are running in the same network. For security reasons, we do not recommend making the database port accessible over a public IP address. If you must make it accessible over a public IP address, we recommend restricting access to a trusted list of source IP addresses using firewall rules. Refer to the FAQ for information on opening ports in the server firewall.

  • Connect to your cloud server using PuTTY or another SSH client (instructions).

  • At the server console, edit the file /opt/bitnami/postgresql/conf/pg_hba.conf and add the following at the end, then save the file:

      host all all all md5
  • Edit the file /opt/bitnami/postgresql/conf/postgresql.conf and replace this line



      listen_addresses = '*'
  • Save the file.

  • Restart the PostgreSQL server:

      $ sudo service bitnami restart

Your PostgreSQL server is now configured to accept remote connections, and you can connect to it using pgAdmin 4. Follow these steps:

  • Launch pgAdmin 4.

  • Go to the “Dashboard” tab. In the “Quick Link” section, click “Add New Server” to add a new connection.

  • Then, configure the connection as follows:

  • Enter your server’s IP address in the “Hostname/Address” field.

  • Specify the “Port” as “5432”.

  • Enter the name of the database in the “Database Maintenance” field.

  • Enter your username as postgres and password (use the same password you used when previously configuring the server to accept remote connections) for the database.

  • Click “Save” to apply the configuration.
