Install Metasploit Framework on Linux Easily

Installing Metasploit Framework on Linux (Step-by-Step Guide)
If you’re learning penetration testing, ethical hacking, or cybersecurity, installing Metasploit Framework on Linux is a must

Open the Terminal and Install Metasploit ​

First, open your Linux terminal.
Then run the following command to download and install Metasploit directly from the official Rapid7 repository:

curl https://raw.githubusercontent.com/rapid7/metasploit-omnibus/master/config/templates/metasploit-framework-wrappers/msfupdate.erb > msfinstall && chmod 755 msfinstall && ./msfinstall

This script adds the required repository and installs the full Metasploit Framework automatically.

​

Start Metasploit Console (msfconsole) ​

After installation finishes, start Metasploit by typing: msfconsole
When prompted to set up a new database, type y or yes.
This step is important because many Metasploit features rely on a database

Initial Database Setup Explained ​

If everything works correctly, you’ll see messages like:

Creating database at ~/.msf4/db
Starting Postgresql
Creating database users
Creating initial database schema

** Metasploit Framework Initial Setup Complete **
[*] Starting the Metasploit Framework console...
[*] The initial module cache will be built in the background (2–5 minutes)

Then the famous Metasploit banner appears
This means Metasploit is ready to use.

​

Verify Database Connection ​

To make sure Metasploit is connected to the database, run: db_status
If successful, you’ll see: postgresql connected to msf
This confirms PostgreSQL is running and Metasploit can store scan results, hosts, and vulnerabilities.

Managing the Metasploit Database ​

If you skipped database creation during the first launch, no worries.
You can manage everything using the msfdb command.

Initialize the Database​

msfdb init

Useful Database Management Commands​

msfdb reinit   # Delete and recreate the database
msfdb delete   # Remove the database completely
msfdb start    # Start the database service
msfdb stop     # Stop the database service
msfdb status   # Check database status

These commands help you troubleshoot and reset your Metasploit environment easily.

Why the Database Matters in Metasploit ​

The database allows Metasploit to:

• Store discovered hosts
• Track open ports and services
• Save vulnerabilities
• Manage exploit sessions

Without it, you lose many powerful features

Final Tips for Beginners ​

• Always run Metasploit as a normal user, not root unless needed
• Keep Metasploit updated
• Use it only in legal and authorized environments
