There is no “fall-through” or “backup”: if one record is chosen and the authentication fails, subsequent records are not considered. The first record with a matching connection type, client address, requested database, and user name is used to perform authentication. Quoting one of the keywords in a database, user, or address field (e.g., all or replication) makes the word lose its special character, and just match a database, user, or host with that name.Įach record specifies a connection type, a client IP address range (if relevant for the connection type), a database name, a user name, and the authentication method to be used for connections matching these parameters. Fields can contain white space if the field value is quoted. A record is made up of a number of fields which are separated by spaces and/or tabs. Records cannot be continued across lines. Blank lines are ignored, as is any text after the # comment character. The general format of the pg_hba.conf file is a set of records, one per line. It is possible to place the authentication configuration file elsewhere, however see the hba_file configuration parameter. (HBA stands for host-based authentication.) A default pg_hba.conf file is installed when the data directory is initialized by initdb. Please continue to read the following: Step 2: Allow the remote client address to access the databaseĪccording to this document, the pg_hba.conf is responsible for client authentication of postgresql:Ĭlient authentication is controlled by a configuration file, which traditionally is named pg_hba.conf and is stored in the database cluster’s data directory. Change the Listen Address in nf On the PostgreSQL database server, by default, the listen address. Modify nf to add Client Authentication Record On the PostgreSQL database server, by default, you’ll notice.

If more than one server is on the local network, it will be necessary to specify a different port than default for PostgreSQL.Īfter that is completed, it will be necessary to also ensure that your network has a static IP address or you are using a DNS forwarding service. This means that all requests to port 5432 are routed to the PostGIS server.
Servers that need to be accessible over the internet for remote workers or workers not able to connect in via a VPN connection need to be routed accordingly by your network hardware. IP address of the physical or virtual serverĬonfiguring for an externally facing server.
All that is required to connect to a PostGIS database on a network then is the following: In most business situations where all employees are under one roof or use a VPN to connect into a business network it is possible to connect directly to the GIS server using its local IP address.īy default, PostgreSQL listens to requests on port 5432. # “local” is for Unix domain socket connections only Sudo nano /etc/postgresql/10/main/pg_hba.conf This file allows access to the database cluster for users with encrypted passwords. Next, use nano to change the pg_hba.conf file. Scroll down to the Connection Settings part of the file using your keyboard and add: Using the Nano text editor, make changes to the nf file by typing: Initializing the database to run on server startupĮither open the terminal in your Linux server or open an SSH session to your server and log in using an appropriate username and run the following command:Įnabling remote connections to the PostgreSQL cluster It assumes PostgreSQL has been installed with the PostGIS extensions already. Similar concepts should apply to other installations. This document uses Ubuntu 18.10 in conjunction with PostgreSQL 10 with PostGIS.
