Installing EDB Postgres Advanced Server on RHEL 9 or OL 9 arm64 v16
Prerequisites
Before you begin the installation process:
Set up the EDB repository.
Setting up the repository is a one-time task. If you have already set up your repository, you don't need to perform this step.
To determine if your repository exists, enter this command:
dnf repolist | grep enterprisedb
If no output is generated, the repository isn't installed.
To set up the EDB repository:
Go to EDB repositories.
Select the button that provides access to the EDB repository.
Select the platform and software that you want to download.
Follow the instructions for setting up the EDB repository.
Install the EPEL repository:
If you are also installing PostGIS, enable additional repositories to resolve dependencies:
Note
If you are using a public cloud RHEL image,
subscription manager
may not be enabled and enabling it may incur unnecessary charges. Equivalent packages may be available under a different name such ascodeready-builder-for-rhel-9-rhui-rpms
. Consult the documentation for the RHEL image you are using to determine how to installcodeready-builder
.
Install the package
Where <xx>
is the version of the EDB Postgres Advanced Server you're installing. For example, if you're installing version 16, the package name is edb-as16-server
.
To install an individual component:
Where package_name
can be any of the available packages from the available package list.
Installing the server package creates an operating system user named enterprisedb. The user is assigned a user ID (UID) and a group ID (GID). The user has no default password. Use the passwd
command to assign a password for the user. The default shell for the user is bash
, and the user's home directory is /var/lib/edb/as16
.
Initial configuration
Getting started with your cluster involves logging in, ensuring the installation and initial configuration was successful, connecting to your cluster, and creating the user password.
First, you need to initialize and start the database cluster. The edb-as-16-setup
script creates a cluster in Oracle-compatible mode with the edb
sample database in the cluster. To create a cluster in Postgres mode, see Initializing the cluster in Postgres mode.
To work in your cluster, log in as the enterprisedb user. Connect to the database server using the psql command-line client. Alternatively, you can use a client of your choice with the appropriate connection string.
The server runs with the peer
or ident
permission by default. You can change the authentication method by modifying the pg_hba.conf
file.
Before changing the authentication method, assign a password to the database superuser, enterprisedb. For more information on changing the authentication, see Modifying the pg_hba.conf file.
Experiment
Now you're ready to create and connect to a database, create a table, insert data in a table, and view the data from the table.
First, use psql to create a database named hr
to hold human resource information.
Connect to the hr
database inside psql:
Create columns to hold department numbers, unique department names, and locations:
Insert values into the dept
table:
View the table data by selecting the values from the table:
