Configure Remote Access for PostgreSQL

By default, PostgreSQL can only be accessed from localhost. To enable remote access, we need to configure some settings. 

Enable Client Authentication

Login as postgres user

su - postgres

Edit the pg_hba.conf

nano /etc/postgresql/9.6/main/pg_hba.conf 

Add the following line to the configuration file:

host all all trust

Make sure you change the IP address with your own.

Enable Networking for PostgreSQL

To allow PostgreSQL to be accessed from the network via TCP/IP, do the following

nano /etc/postgresql/9.6/main/postgresql.conf 

Find the following line


Change it to


Close and save the file. Finally, restart PostgreSQL service

sudo systemctl restart postgresql
