Install and configure pgAdmin 4 on Ubuntu 18.04

Prerequisites

Before you begin, you will need the following:

• An Ubuntu 18.04 server with a non-root user with sudo privileges.
• Internet access to download the pgAdmin 4 deb package.

Step 1: Install pgAdmin 4

To install pgAdmin 4, you can use the following commands:

 sudo apt update sudo apt install pgadmin4 

This will install the pgAdmin 4 package from the official Ubuntu repositories.

Step 2: Configure pgAdmin 4

Once pgAdmin 4 is installed, you need to configure it to connect to your PostgreSQL server. To do this, open the pgAdmin 4 application and click on the "File" menu, then "Add Server".

In the "Add Server" dialog box, enter the following information:

• Name: Enter a name for your server.
• Host: Enter the hostname or IP address of your PostgreSQL server.
• Port: Enter the port number of your PostgreSQL server.
• Username: Enter the username of your PostgreSQL user.
• Password: Enter the password of your PostgreSQL user.

Once you have entered all of the required information, click on the "Save" button.

Step 3: Use pgAdmin 4

Once you have configured pgAdmin 4, you can use it to manage your PostgreSQL server. To do this, open the pgAdmin 4 application and click on the "Servers" tab. You will see a list of all of the servers that you have configured.

To connect to a server, double-click on its name. You will then be able to view the databases, tables, and other objects on the server.

You can also use pgAdmin 4 to perform administrative tasks, such as creating and deleting databases, tables, and users.
