Locate the line: #listen_addresses = ‘localhost’ and change it to *: listen_addresses = '*' There are detailed comments in the file to guide you.īy default only connections from the local system are allowed, to enable all other computers to connect to your PostgreSQL server, edit the file /etc/postgresql/*/main/nf. To configure IDENT authentication, add entries to the /etc/postgresql/*/main/pg_nf file. For example, if you install PostgreSQL 14, the configuration files are stored in the /etc/postgresql/14/main directory. PostgreSQL configuration files are stored in the /etc/postgresql//main directory. The following discussion assumes that you wish to enable TCP/IP connections and use the MD5 method for client authentication. Please refer to the PostgreSQL Administrator’s Guide if you would like to configure alternatives like Kerberos. In Ubuntu, peer is the default authentication method used for local connections, while scram-sha-256 is the default for host connections (this used to be md5 until Ubuntu 21.10). PostgreSQL supports multiple client authentication methods. The database service is automatically configured with viable defaults, but can be customised based on your specific needs. To install PostgreSQL, run the following command in the command prompt: sudo apt install postgresql PostgreSQL (also known as Postgres) is an object-relational database system that has the features of traditional commercial database systems with enhancements to be found in next-generation database management systems (DBMS).
