11/8/2023 0 Comments Configure postgresql tcpThe server will listen for both normal and SSL connections on the same TCP port, and will negotiate with any connecting client on whether to use SSL. The documentation for the current version of Postgresql 9.6 can be found here Previous versions are also available near that link but in the case of pg_hba.conf things do not appear to have changed between versions. The packaged PostgreSQL server can be configured to listen for TCP/IP connections, with the caveat that some non-critical scripts expect UNIX sockets and. Basic Setup With SSL support compiled in, the PostgreSQL server can be started with support for encrypted connections using TLS protocols enabled by setting the parameter ssl to on in nf. This basically says "Anybody from anywhere can access my Postgresql server" I have provided it simply as an example of how careful you have to be. If you were particularly reckless and irrisponsible and enjoy the prospect of living dangerously and with regular intervals of fear and loathing you would use the following line in your pg_hba.conf file, although I seriously council against it. I'm creating a PostgreSQL container using the following command: docker run -p 5432:5432 -e POSTGRESPASSWORD123456789 -d postgres:9.3. The above example will get you going but it would be wise to go and briefly read the postgresql documentation for the pg_hba.conf file. If you wish to allow all computers in your subnet to access your Postgresql server you may do something like the following: # IPv4 local connections: This step is required on manually configured remote database servers. This says that only allow the hosts that match 127.0.0.1/32 to access my server. Allow TCP/IP connections to the database. ( HBA stands for host-based authentication.) A default nf file is installed when the data directory is initialized by initdb. The following snippet is from my own Postgresql server: # IPv4 local connections: Client authentication is controlled by a configuration file, which traditionally is named nf and is stored in the database clusters data directory. By default it only allows a user local to the server to connect to the database. In addition to a TCP listening port, PostgreSQL will also a local socket if the server is running in a Linux/ Unix environment. To allow users in the wide world to access your server is unwise. The default TCP port for PostgreSQL is usually 5432, however this can easily be changed in the nf configuration file, which is the main configuration file for the database server. With SSL support compiled in, the PostgreSQL server can be started with SSL enabled by setting the parameter ssl to on in nf. To allow yourself access to the server to administer it on the same subnet is very easy. Are you wanting to administer Postgresql from the local network or are you wanting to allow other users in the wide world to connect to your Postgresql server?
