About this Hands-on Lab

Installing and managing services is one of the first things a Linux Server Administrator should learn how to do. The standard example of a web service is a “LAMP stack” – Linux, Apache, MySQL, PHP. In this lab, we’ll practice installing and configuring Apache on a Linux server.

Learning Objectives

Successfully complete this lab by achieving the following learning objectives:

Install and Configure Apache

  1. Now we need to install the software. Run the following command:

    yum install httpd -y

    Start the httpd service with:

    systemctl start httpd

  2. Now we’ve been directed to use a specific DocumentRoot. So we need to edit the configuration file to set that correctly.

    vim /etc/httpd/conf/httpd.conf

  3. In that file, search for the DocumentRoot by typing /DocumentRoot. The DocumentRoot section is the path that the httpd service uses to produce an app/website.

  4. Set line 119, DocumentRoot, to "/opt/website". Also, set the <Directory> tags in lines 124, and 131 to <Directory /opt/website>.

  5. Save and quit the file with :wq.

  6. Restart to initiate changes to the file:

    systemctl restart httpd
Test the Configuration
  1. Verify the webpage is accessible by "curling" your server:
    curl localhost
  2. Go to a browser (e.g. Chrome) and paste in the IP address of the Cloud Server. If successful, you’ll see a great website. We hope you love dad jokes!

Additional Resources

You have just started working at DadCorp, a new startup providing a subscription service that emails dad jokes to customers. The majority of the data center is web servers containing the sign-up forms.

When the load gets too high, a new webserver is built. You've received your first ticket to set up a new web server. You've already deployed a CentOS 7 server, now you just need to deploy Apache and set the Document Root to /opt/website which is where the developers have already placed their code.

To get started, we need to log in to our servers:

  1. Use ssh and the provided lab credentials to log in to our server. Be sure to keep the Cloud Server's public IP handy. You'll need it momentarily:

    ssh cloud_user@<PUBIC_IP>

  2. Become the root user:

    sudo -i
