The superuser password is required every time a user logs into the Postgres server. While installing Postgres, users specify a superuser password that must be remembered for later use. In database management systems, like PostgreSQL, passwords are considered the primary protection parameter against cybercrime. Passwords protect the data and prevent a database from unauthorized access. In this guide, we successfully installed PgAdmin4 on Rocky Linux and AlmaLinux and added a database server to monitor the performance of databases.Passwords play a very crucial role in our lives. Click on it to view additional database details and view the performance dashboards. Upon successful connection, the database server will appear on the left sidebar. The password belongs to the postgres user. Here we are using the default Postgres database and user credentials. Then click on the ‘ Connection’ tab and fill out the required details. In our case, we will provide an arbitrary name – the local PostgreSQL database. On the ‘ General’ section, provide a name for your database server. To connect to a new database server, click on the ‘ Add New Server‘ icon. PgAdmin Dashboardīy default, no database server is currently connected. The PgAdmin 4 dashboard will come to view. the email address and the password that you previously set, and hit the ‘ Login’ button. $ sudo firewall-cmd -reloadįinally, to log in, launch your browser and visit the URL: Enter the login credentials, i.e. $ sudo firewall-cmd -permanent -add-service=http We also need to configure the firewall to allow HTTP traffic as shown. If SELinux is on enforcing mode, set it to permissive mode as shown. Setup PgAdmin in Rocky Linuxīefore we access the PgAdmin4 web GUI, we need to adjust our SELinux settings. Therefore, provide your email address and password, and press ‘y’ to restart the Apache webserver. These will, later on, be used for authentication. The script sets up PgAdmin4 in web mode and prompts for details such as the email address and the password. Moving on, we can now proceed to configure PgAdmin4 by running the PgAdmin4 setup script as shown: $ sudo /usr/pgadmin4/bin/setup-web.sh Verify Apache in Rocky Linux Step 4: Set Up PgAdmin4 in Rocky Linux To verify that Apache is running, execute the command: $ sudo systemctl status httpd Once enabled, proceed and start the Apache service as follows. To enable Apache web server, run the command: $ sudo systemctl enable httpd This is necessary since PgAdmin4 runs on a webserver. Install PgAdmin in Rocky Linux Step 3: Start and Enable Apache Webserverīefore setting up PgAdmin4, we need to start the Apache webserver service. Press ‘Y’ when prompted to install all the packages and dependencies. This installs pgAdmin4, Apache webserver alongside other dependencies that are required by PgAdmin4. Next, install pgAdmin 4 by running the command: $ sudo dnf install pgadmin4 Once the PgAdmin4 repository is in place, update the system repositories. Once the command has run successfully, install the PgAdmin4 repository. $ sudo yum-config-manager -disable pgdg-common Next, disable the PostgreSQL common repositories to prepare for the installation of the latest PgAdmin4 packages. But first, install the yum-utils package. To install PgAdmin4, the first step will be to add the PgAdmin4 repository. Step 1: Add the PgAdmin4 Repository on Rocky Linux Already, we have a guide on how to install PostgreSQL on Rocky Linux and AlmaLinux. PrerequisitesĪs a requirement, you need to have PostgreSQL installed. In this article, we focus on how you can install PgAdmin4 on Rocky Linux and AlmaLinux. Responsive web interface, and so much more.Powerful and easy-to-use tools for everyday database administrative tasks.Live SQL query tool for directly editing the data.Redesigned and new-look user interface.It’s written in Python and Javascript/JQuery and is an improvement of its predecessor PgAdmin. PgAdmin 4 allows administrators to seamlessly manage PostgreSQL databases from a web browser and run SQL queries among other database tasks. PgAdmin 4 is an open-source, powerful, and front-end PostgreSQL database administration tool.
