Therefore, we have to add PostgreSQL yum repository in our CentOS 7 server and then we will be able to install PostgreSQL 11. In CentOS 7.6, PostgreSQL 9.2 is available in standard yum repositories.īut we are required to install latest version of PostgreSQL i.e. We have configured a CentOS 7 virtual machine with following specifications.Ĭonnect with using ssh as root user.

PgAdmin is the most popular open source and feature enrich web interface for administration of PostgreSQL database servers.

You can modify the configuration of the configuration file, such as the port. Will generate database instance related information under the path, such as nf, pg_hba.conf The so-called Database Cluster is the directory used to store all database instance information, initialized by the initdb command. 4, start vs stop, register Windows serviceĭetailed manual 2, after decompression, add environment configurationįor example, after decompressing the path: D:\Programs\pgsql\binĪdd to the Windows environment variable PATH for easy invocation 3, create a Database Cluster.2, after decompression, add environment configuration.
