In the process, it will ask you to enter the password from the postgres super user of the postgres database. app/postgresql/bin/initdb -D /app/postgresql/pgdatabase/data/ -U postgres -W Initialization is the process of creating all the necessary directories for the database itself. The assembly procedure will take about 5 minutes.Īfter the assembly, we begin the process of installing the database itself. We collect the DBMS from the source files. app/postgresql/build/configure -prefix=/app/postgresql In the /app/postgresql/build directory, run: And now we can delete the archive itself. Now it starts to unpack the archive itself.Īfter unpacking, we get the postgresql-14.1 directory.Ĭhange the name of postgresql-14.1 to build. We will download the database archive on the official website.Īll further actions are performed under the postgres user.Īfter downloading the archive, move it to the /app/postgresql directory. Now let's assign the new postgres owner we created to the /app root directory. sudo mkdir -p /app/postgresql/pgdatabase/logĮnough for now, then there will be another directory with utilities for managing the database. sudo mkdir -p /app/postgresql/pgdatabase/data ![]() We create directories where the subd and the database will be stored. Create a local user on the server named postgres.Ĭreate a postgres user and set a password for it. sudo dnf install gcc zlib-devel readline-devel make ![]() We create our environment for the database.īefore installation, it is necessary to install important packages without which the installation of the database itself will not be possible.Editing nf and pg_hba.conf configuration files.Create a local user on the server named postgres.PostgreSQL is an open source generic object-relational database management system that is a real alternative to commercial databases.

Not sure why I still get a permission denied, since postgres should have all necessary rights as owner of the folder: $ ls -lĭrwxrwxrwx.In this article, we will discuss how to install a PostgreSQL database server on Linux from source.

Starting postgres service doesn't works now, because of the new data_directory path within the nf.
