Tools to check ports during any step 0.1 nc or netcat nc -zv 4.3.2.1 5432 Where -v Produce more verbose output. Secondly, you need to change the permissions inside pg_hba.conf file (on CentOS, the default location is /var/lib/pgsql/data/pg_hba.conf) nano /var/lib/pgsql/data/pg_hba.conf Configure PostgreSQL to accept remote connections 3.1 Finding the above configuration files 3.2 nf 3.3 nf 0. PostgreSQL uses a maxconnections setting to limit the number of connections (and resources that are consumed by connections) to prevent run-away connection. When you have only access from localhost (from localhost Apache, by example) everything is ok, but when you need that postgresql accepts connections for other hosts, you need to make some configs. Search the following line: listen_addresses = 'localhost' By default, on some distros, PostgreSQL will only accept connections from localhost. To enable persistent connection, the pgsql.allowpersistent php.ini directive. When you have only access from localhost (from localhost Apache, by example) everything is ok, but when you need that postgresql accepts connections for other hosts, you need to make some configs.įirst of all, edit the nf file (on CentOS the default location is /var/lib/pgsql/data/nf). See an in depth description of this approach in the anwser of the following question: How to close idle connections in PostgreSQL. Now we are able to connect to postgresql server remotely. You should be able to see list of databases. Once those idle connections are found, a simple call to pgterminatebackend will close them. 1 2 psql -h 107.170.158.89 -U postgres 3 Password for user postgres: 4 psql (9.4.1, server 9.4.5) 5 Type 'help' for help. Wrote by Rafael Marangoni, from Consultoria Linux team.īy default, on some distros, PostgreSQL will only accept connections from localhost. Another approach would consist in using some cron-like tool running a query periodically to find idle connections. ![]()
