About this Hands-on Lab

In this hands-on lab, we will be using the RPM command to manage our software installations. This may be something you are tasked with to show your proficiency with software management tools.

Learning Objectives

Successfully complete this lab by achieving the following learning objectives:

Using a File from the Packages List, Get the Package Version for the Apache2 Installation

Run the following commands:

rpm -ql apache2
rpm -qf /var/lib/apache2
In the `default-server.conf`, Modify the Document Root
  1. List the configuration files to locate the default-server.conf:

    rpm -qc apache2
  2. Modify the configuration file:

    sudo vim /etc/apache2/default-server.conf
  3. Change the section dealing with document root — we need to change two places.

    Change this:

    #
    # Global configuration that will be applicable for all virtual hosts, unless
    # deleted here, or `overriden` elswhere.
    # 
    
    DocumentRoot "/srv/www/htdocs" .  <<<-- change this line
    
    #
    # Configure the DocumentRoot
    #
    <Directory "/srv/www/htdocs">    <<<-- change this line
        # Possible values for the Options directive are "None", "All",
        # or any combination of:
    ...

    To this:

    #
    # Global configuration that will be applicable for all virtual hosts, unless
    # deleted here, or overriden elswhere.
    # 
    
    DocumentRoot "/var/www/htdocs" <<<-- to this line
    
    #
    # Configure the DocumentRoot
    #
    <Directory "/var/www/htdocs"> << -- to this line
        # Possible values for the Options directive are "None", "All",
        # or any combination of:
    ...
Use Rsync to Copy the Old Doc Root to the New Doc Root and Create an `index` File Containing the string `new doc root`
  1. Use rsync to synchronize the doc root:

    sudo rsync -avr /srv/www /var
  2. Create an index.html file in the new doc root with the string new doc root:

    cd /var/www/htdocs/
    sudo touch index.html
    sudo vim index.html
    <<< ensure you put the string into the index.html file>>>
Verify the Package Files and Ensure the `server-default.conf` is Listed as Changed. Start Apache2 and Ensure the New `index` Loads.
  1. Run the following:

    rpm -V apache2
  2. Start Apache and check the index:

    sudo systemctl start apache2
    curl 127.0.0.1

    The result should be the string inserted in the previous task.

Additional Resources

You are interviewing for a position as a web administrator for a large enterprise. You have been tasked with showing your abilities by demonstrating knowledge of the rpm command and its use. Using the rpm command where applicable, complete the following tasks.

  • Apache2 has been installed via Zypper. Get a list of its files and, using a file in this list, determine the version of the package from which Apache2 was installed.
  • Determine the location of the Apache2 default-server.conf, and then modify the location of the document root.
  • Use Rsync to copy the old doc root to the new location.
  • In the new doc root, create an index.html that loads the string new doc root.
  • Verify the files in the package and show that the changed default-server.conf is in the list.
  • Start the Apache2 service and curl 127.0.0.1 to ensure the new index loads.
