How to Install PgAdmin 4 on Debian 11

how to install pgadmin 4 on debian 11

pgAdmin is a powerful and feature-rich administration tool with a user-friendly web-based interface. It’s a database management tool for one of the most popular open-source RDMB systems, PostgreSQL.

pgAdmin is used by new and experienced Postgres users, with pgAdmin features like Query Tool, ERD Tool for designing and documenting schemas, Monitoring dashboard, and other features. In this tutorial, we will show you how to install pgAdmin 4 on a Debian 11 server.


  • A Debian 11 VPS
  • Access to the root user account (or access to an admin account with root privileges)

Step 1: Log in to the Server & Update the Server OS Packages

First, log in to your Debian 11 server via SSH as the root user:

ssh root@IP_Address -p Port_number
apt-get update -y

Step 2: Install PostgreSQL

Before installing pgAdmin4, the PostgreSQL server must be installed on your server. If not installed, you can install it using the following command:

# apt-get install postgresql

You can check if PostgreSQL has been installed and running with the systemctl status command:

# systemctl status postgresql
● postgresql.service - PostgreSQL RDBMS
Loaded: loaded (/lib/systemd/system/postgresql.service; enabled; vendor pr>
Active: active (exited) since Tue 2023-06-20 15:33:18 CDT; 2min 56s ago
Main PID: 2786 (code=exited, status=0/SUCCESS)
Tasks: 0 (limit: 4148)
Memory: 0B
CPU: 0
CGroup: /system.slice/postgresql.service

You can enable PostgreSQL to start with every system reboot using the command:

systemctl enable postgresql

Step 3: Create a PostgreSQL Database and User

Next, you can connect to the PostgreSQL shell and create a new database and new user:

# su - postgres
# psql

Once you are connected, to create a user called dbuser with a given password, you can use the following command:

postgres= CREATE USER dbuser WITH PASSWORD 'password';

Now you can also create a new database:

postgres= CREATE DATABASE pgdb;

Next, grant all the privileges to the PostgreSQL database with the following command:

postgres= GRANT ALL PRIVILEGES ON DATABASE pgdb to pguser;

Next, exit from the PostgreSQL shell with the following command:

postgres= \q

Step 4. Install pgAdmin 4

By default, pgAdmin4 is not included in the Debian 11 default repository. So you will need to add the pgAdmin4 repository in APT.

echo "deb pgadmin4 main"\
| sudo tee /etc/apt/sources.list.d/pgadmin4.list

Import the GPG key of the pgAdmin repository using the following command:

After that, update apt, and you can install pgAdmin using the following commands below:

sudo apt update
sudo apt install pgadmin4-web

Step 4. Configure pgAdmin.

Now we set up pgAdmin 4 before accessing it:

sudo /usr/pgadmin4/bin/

You will be asked to provide your Email and password to finish the configuration as shown below:
