Prerequisites

Before you begin the installation process:

  • Set up the repository Setting up the repository is a one-time task. If you have already set up your repository, you do not need to perform this step.

    To set up the repository, go to EDB repositories and follow the instructions provided there.

  • Install the EPEL repository

    sudo yum -y install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

Install the package

sudo yum -y install edb-as<xx>-server

Where <xx> is the version of the EDB Postgres Advanced server you are installing. For example, if you are installing version 15, the package name would be edb-as15-server.

To install an individual component:

sudo yum -y install <package_name>

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/as15.

Initial configuration

This section steps you through getting started with your cluster including logging in, ensuring the installation and initial configuration was successful, connecting to your cluster, and creating the user password.

# Initialize the database cluster
PGSETUP_INITDB_OPTIONS="-E UTF-8" /usr/edb/as15/bin/edb-as-15-setup initdb

# Start the database cluster

\c hr
CREATE TABLE public.dept (deptno numeric(2) NOT NULL CONSTRAINT dept_pk
PRIMARY KEY, dname varchar(14) CONSTRAINT dept_dname_uq UNIQUE, loc
varchar(13));

# Add data to the table
INSERT INTO dept VALUES (10,'ACCOUNTING','NEW YORK');
INSERT into dept VALUES (20,'RESEARCH','DALLAS');

# You can use simple SQL commands to query the database and retrieve
# information about the data you have added to the table
SELECT * FROM dept;
