Methods to Install Postman on Rocky Linux 9

There are two primary methods to install Postman on Rocky Linux 9: using the Snap package manager and manual installation from a tarball. We’ll cover both approaches in detail.

Installing Postman via Snap Package Manager

The Snap package manager offers a convenient way to install and manage applications on Linux systems. Here’s how to use it to install Postman:

Step 1: Install Snap

First, we need to install the Snap package manager if it’s not already present on your system. Run the following command:

sudo dnf install snapd -y

Step 2: Enable Snap Socket

After installing Snap, enable the Snap socket and start the service:

sudo systemctl enable --now snapd.socket
sudo ln -s /var/lib/snapd/snap /snap

Step 3: Install Postman

Now that Snap is set up, we can install Postman with a single command:

sudo snap install postman

This command will download and install the latest version of Postman on your Rocky Linux 9 system.

Verification

To verify that Postman has been installed correctly, simply type the following command in your terminal:

postman

If the installation was successful, Postman should launch.

Advantages of Using Snap

Installing Postman via Snap offers several benefits:

• Automatic updates ensure you always have the latest version
• Easy installation and removal process
• Consistent experience across different Linux distributions

Manual Installation from Tarball

For users who prefer more control over the installation process or cannot use Snap, manual installation from a tarball is an excellent alternative.

Step 1: Download Postman

First, download the latest Postman tarball using wget:

wget https://dl.pstmn.io/download/latest/linux64 -O postman.tar.gz

Step 2: Extract the Tarball

Extract the downloaded tarball using the tar command:

tar -xvzf postman.tar.gz

Step 3: Move Postman to the Appropriate Directory

Move the extracted Postman directory to the /opt directory:

sudo mv Postman /opt/

Step 4: Create a Symbolic Link

Create a symbolic link to make Postman accessible system-wide:

sudo ln -s /opt/Postman/Postman /usr/local/bin/postman

Creating a Desktop Shortcut

To create a desktop shortcut for easy access to Postman:

1. Navigate to the applications directory:

cd ~/.local/share/applications/

2. Create a new .desktop file:

nano ~/.local/share/applications/postman.desktop

3. Add the following content to the file:

[Desktop Entry]
Name=Postman
Exec=/opt/Postman/Postman
Icon=/opt/Postman/app/resources/app/assets/icon.png
Type=Application
Categories=Development;
Terminal=false

4. Save the file and exit the text editor.

Verification

To verify the manual installation, you can either launch Postman from the applications menu or type ‘postman’ in the terminal.

Installing Postman CLI (Optional)

For advanced users who prefer working with a command-line interface, Postman offers a CLI version. To install it, run:

curl -o- "https://dl-cli.pstmn.io/install/linux64.sh" | sh

The Postman CLI provides additional features like running collections, linting API schemas, and performing security checks, making it a powerful tool for automation and integration into CI/CD pipelines.

Troubleshooting Common Issues

Even with careful installation, you might encounter some issues. Here are solutions to common problems:

Snap-related Issues

If Snap commands fail, ensure that the Snap socket is enabled:

sudo systemctl enable --now snapd.socket

Permission Errors During Manual Installation

If you encounter permission errors, make sure you have the correct permissions for the /opt/Postman directory:

sudo chmod -R 755 /opt/Postman

Postman Not Appearing in Applications Menu

If Postman doesn’t appear in your applications menu after creating the .desktop file, run:

sudo update-desktop-database

This command updates the system’s database of desktop entries.
