This tutorial shows you how to install pgAdmin 4 on Ubuntu 20.04/18.04/16.04. pgAdmin is an open-source PostgreSQL administration and development tool, pgAdmin is basically used for managing the PostgreSQL database server.
You must have a PostgreSQL server on a Local or remote System/VM. If you don’t have then refer to the below document and install PostgreSQL. For this tutorial, I have installed the PostgreSQL server and pgAdmin tool on the same Ubuntu system.
How To Install PostgreSQL 12 on Ubuntu 20.04/18.04/16.04
Step to Install pgAdmin4 on Ubuntu
Step 1: Add PostgreSQL APT repository
wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo apt-key add - sudo sh -c 'echo "deb https://ftp.postgresql.org/pub/pgadmin/pgadmin4/apt/$(lsb_release -cs) pgadmin4 main" > /etc/apt/sources.list.d/pgadmin4.list && apt update'
Sample Output:
root@PostgreSQL:~# wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo apt-key add - Warning: apt-key is deprecated. Manage keyring files in trusted.gpg.d instead (see apt-key(8)). OK root@PostgreSQL:~# sudo sh -c 'echo "deb https://ftp.postgresql.org/pub/pgadmin/pgadmin4/apt/$(lsb_release -cs) pgadmin4 main" > /etc/apt/sources.list.d/pgadmin4.list && apt update' Hit:1 http://us.archive.ubuntu.com/ubuntu groovy InRelease Hit:2 http://security.ubuntu.com/ubuntu groovy-security InRelease Hit:3 http://us.archive.ubuntu.com/ubuntu groovy-updates InRelease Hit:4 https://ftp.postgresql.org/pub/pgadmin/pgadmin4/apt/groovy pgadmin4 InRelease Hit:5 http://us.archive.ubuntu.com/ubuntu groovy-backports InRelease Reading package lists...

Step 2: Install pgAdmin4 on Ubuntu
sudo apt install pgadmin4

Step 3: Configure pgAdmin4 credentials
sudo /usr/pgadmin4/bin/setup-web.sh
Replace Email ID admin@sysadminxpert.local and configure your strong password.
After installation Apache service will be started
$ systemctl status apache2
Sample Output:
root@PostgreSQL:~# systemctl status apache2 ● apache2.service - The Apache HTTP Server Loaded: loaded (/lib/systemd/system/apache2.service; enabled; vendor pres> Active: active (running) since Sun 2021-05-16 12:28:13 EDT; 4min 37s ago Docs: https://httpd.apache.org/docs/2.4/ Process: 25828 ExecStart=/usr/sbin/apachectl start (code=exited, status=0/> Main PID: 25832 (apache2) Tasks: 34 (limit: 4648) Memory: 33.9M CGroup: /system.slice/apache2.service ├─25832 /usr/sbin/apache2 -k start ├─25833 /usr/sbin/apache2 -k start ├─25834 /usr/sbin/apache2 -k start ├─25835 /usr/sbin/apache2 -k start ├─25836 /usr/sbin/apache2 -k start ├─25837 /usr/sbin/apache2 -k start └─25838 /usr/sbin/apache2 -k start May 16 12:28:12 PostgreSQL systemd[1]: Starting The Apache HTTP Server...

Step 4: Configure firewall on Ubuntu (Optional)
sudo ufw allow http sudo ufw allow https
Sample Output:
root@PostgreSQL:~# sudo ufw allow http Rules updated Rules updated (v6) root@PostgreSQL:~# sudo ufw allow https Rules updated Rules updated (v6) root@PostgreSQL:~#
Step 5: Access pgadmin4 on web browser
http://[ServerIP_or_domain]/pgadmin4
Login with Credentials which we have created in step 3
Once you login you will get the below screen.
Step 6: Add a PostgreSQL server to administer with pgAdmin
Click on “Add New Server” (you can add local or remote PostgreSQL server)
Under the “General” section, Give PostgreSQL server name with description
Now, click on the “Connection tab”, provide server details like PostgreSQL IP/host, database user, and password
Now save it. If all configuration is correct you will be able to see the PostgreSQL server on the left side.
