  1. Create a symbolic link of Python3.8 binary to /usr/local/bin/python.

     $ sudo ln -s /usr/local/bin/python3.8 /usr/local/bin/python
  2. Install and upgrade pip, which is a package manager for Python.

     $ sudo pkg install py38-pip
     $ sudo pip install --upgrade pip
  3. Install the virtualenv package, which is used to create isolated Python environments.

     $ sudo pkg install py38-virtualenv
  4. Create a virtual environment for pgAdmin.

     $ virtualenv pgadmin4
  5. Activate the Virtual environment.

     $ . pgadmin4/bin/activate
  6. Install Python dependencies.

     $ sudo pip install cryptography==3.1.1 pyopenssl ndg-httpsclient pyasn1 simple-websocket
  7. Install Python SQLite3 package.

     $ sudo pkg install py38-sqlite3
  8. Download and install Python wheel package for pgAdmin. To get the latest version, go to pgAdmin wheel packages.

  9. Create the data directories and give write permissions.

     $ sudo mkdir -pv /var/lib/pgadmin
     $ sudo chmod 770 /var/lib/pgadmin
     $ sudo mkdir -pv /var/log/pgadmin
     $ sudo chmod 770 /var/log/pgadmin
  10. Install the nano editor.

     $ sudo pkg install nano
  11. Copy the pgAdmin configuration file.

     $ sudo cp ./pgadmin4/lib/python3.8/site-packages/pgadmin4/ ./pgadmin4/lib/python3.8/site-packages/pgadmin4/
  12. Edit the configuration file.

     $ sudo nano ./pgadmin4/lib/python3.8/site-packages/pgadmin4/
  13. Find the line DEFAULT_SERVER = '' and change it to match the line below.

  14. Save and exit the file.

  15. Run pgAdmin 4.

     $ sudo python pgadmin4/lib/python3.8/site-packages/pgadmin4/
  16. Enter your email address and password to create your pgAdmin administrator account.

  17. Open your browser and navigate to your server's IP address at port 5050 to access the pgAdmin 4 user interface. Use the email address and password that you set in the previous step. For example:

3. Connect to the Database Server with pgAdmin 4

  1. Go to the pgAdmin 4 web portal and click Add New Server.

    Add new server

  2. You'll be prompted with a dialog box. Enter your preferred server name in the Name field.

    Server Name

  3. Switch to the Connection tab and enter the required fields with the appropriate data.

    • Enter localhost under the Host name/address.
    • Leave Port value as 5432.
    • Enter testdb under Maintenance database.
    • Enter pgadmin under Username.
    • Enter the database password you chose in section 1.
    • Click Save to login to the server.

    Third step

  4. After a successful connection, choose your server in the upper left corner, then expand the arrows to access the testdb database.

    Fourth step


You have installed pgAdmin 4 for PostgreSQL Server. You can now manage your database server via the dashboard.
