Problem Statement

In response to heightened security concerns, the xFusionCorp Industries security team has opted for custom Apache users for their web applications. Each user is tailored specifically for an application, enhancing security measures. Your task is to create a custom Apache user according to the outlined specifications:

a. Create a user named john on App server 3 within the Stratos Datacenter.

b. Assign a unique UID 1321 and designate the home directory as /var/www/john.

Solution

Steps to Create and Configure the User

  1. Log in to App Server 3: First, connect to the application server using SSH. Execute the following command from your local machine:

    ssh banner@stapp03

    Here, banner is the username you use to access the server, and stapp03 is the hostname of App Server 3.

  2. Switch to the Root User: Once logged in, escalate your privileges to the root user to perform administrative tasks. Use the following command:

    sudo su

    This command will prompt you for the root password or your user password, depending on your sudo configuration.

  3. Create the User with a Specific UID: With root privileges, create a new user named john and assign a unique user ID (UID) of 1321. Run the following command:

    useradd -u 1321 john

    The -u option specifies the UID, and john is the username. By default, this command creates a home directory for the user at /home/john.

  4. Set the Custom Home Directory: Change the default home directory to /var/www/john. This step is necessary to align with the specified directory structure for web applications. Use the following command:

    usermod -d /var/www/john john

    The -d option updates the user's home directory path.

  5. Verify the User Configuration: To ensure that the user john has been created with the correct UID and home directory, check the user information in the /etc/passwd file. Execute the following command:

    grep john /etc/passwd

    You should see an output similar to:

    john:x:1321:1321::/var/www/john:/bin/bash

    In this output:

    • john is the username.
    • x indicates that the password is managed through shadow files.
    • 1321 is the UID and GID (group ID).
    • /var/www/john is the home directory.
    • /bin/bash is the default shell.
