Refer to your instructor for submission instructions


Important.png
It is YOUR responsibility to Backup your centos3 VM for this Assignment!
You are required to frequently backup your VM prior to exiting a work session during this assignment. Your instructor will NOT accept the fact that your hard disk crashed and lost all of your work. If you properly backed up your VM images and xml configuration files to a USB, then you can purchase a new hard-disk or wipe and recreate your hard disk and restore your VMs.

Introduction and Purpose

In this assignment, you will demonstrate the skills you have learned to this point by configuring two services: a database server and a web server. You will install and use a database-backed web application, Wordpress, to show that these services have been installed properly. You will also configure the SELinux security system to further enhance the security of your computer system.

NOTE: Do this assignment inside the centos3 virtual machine.

Installing Packages

Install these packages using yum

  • httpd - this is the Apache web server software.
  • php - this is the PHP server software, which allows Apache to run more complex websites.
  • php-mysql - this is a PHP extension that allows PHP to use a MySQL server.


Install the mysql-server (MySQL database server) package

NOTE: This package may not be in the main repository. There a couple of options:

  • Preferred method: Use an alternative package (for example: mariadb and mariadb-server)
  • Download a "zipped tar-ball" from a website (google-search), decompress, and compile

Configuring Apache

  1. Start the httpd service using systemctl.
  2. Ensure that the httpd service starts automatically during boot.
  3. Confirm that you can connect to your web server using a web browser -- both from centos3 (you can test using links) as well as from the host. You should see the Apache Test Page.
  4. If you can't connect to it from outside the machine - perhaps your firewall is blocking access to the web server.

Configuring MySQL

  1. Start the MySQL service (mysqld or mariadb) using systemctl.
  2. Ensure that the mysqld/mariadb service starts automatically during boot.
  3. You may get messages after starting the MySQL service for the first time. Do not ignore these messages, it will tell you how to set a password and take other basic steps to secure the the MySQL server. Follow those instructions to set a password, recording the detail of what you do for later use.
    • If you do not see any messages, research how you can secure the MySQL installation and set the MySQL-root password.
    • Read those messages carefully, you are setting up a production MySQL server and there shouldn't be any "test" databases or anonymous users or users without a password.
  4. Set your MySQL root password to your learn ID (without the @senecac.on.ca part).
  5. This following part is challenging so take your time and read the instructions to make sure you do it properly, we have to set up a dedicated user and database for wordpress:
    1. Start by looking at http://codex.wordpress.org/Installing_WordPress#Using_the_MySQL_Client where you will find instructions for the setup.
    2. You will need to run those commands in a centos3 terminal.
    3. Your adminusername is root
    4. Your databasename is myblog
    5. Your wordpressusername is your learn ID
    6. The password should also be your learn ID
    7. Your hostname is localhost

Installing and Configuring Wordpress

Wordpress (like most web applications) is not available in the Fedora repositories, it must be downloaded and installed manually.

  1. Download the latest .tar.gz version from wodpress.org into your centos3 (use wget).
  2. Extract it into /var/www/html
  3. Now we need to allow Apache to modify the wordpress installation. To do this use chown -R to make the owner and group of every file and directory inside wordpress "apache".
  4. Check your work so far by pointing your web browser to http://centos3/wordpress/ where you will get an error starting with "There doesn't seem to be a wp-config.php file"
  5. Copy the wp-config-sample.php file to wp-config.php and edit the new file:
    • Change the DB_NAME, DB_USER, DB_PASSWORD to the appropriate values.
  6. Now go back to http://centos3/wordpress/ - you should see a Wordpress Welcome/Setup page.
    • Set the title to Your Name's Blog. For example for me it would be "Andrew Smith's Blog"
    • Set the password to your learn ID.
    • Set the email to your Seneca email address.
    • Click "Install Wordpress", you should see a "Success!" message.

Write-up

Write a blog post on your new blog explaining:

  • What is Apache, PHP, MySQL, and Wordpress.
  • What problems (minor and major) you ran into during the installation and how you solved them.

Write a second post on your blog explaining:

  • Are you ready for the exam or not.
  • List the material you are strong on.
  • List the material you are worried about.
  • List any questions or topics you would like me to address during exam review.

Make your posts look professional. That means use good english, headings, bullet or numbered lists, etc.

Submitting Your Assignment

Due date: Your name will be called in the lab on the due date for the assignment. If you are not there when your name is called - you will lose 20% of your mark. In that case you may show me your submission in the second lab that week instead. Assignments submitted after that will receive a grade of 0, but must still be completed satisfactorily in order to pass the course.

Ready to show

Open one or more terminals in c7host, SSH to centos3 from those terminals, and have the following ready:

  • The correct RPMs are installed
  • Output showing firewall has been properly set up
  • Output of chkconfig --list mysqld
  • Output of chkconfig --list httpd
  • MySQL output of: show databases; use mysql; select User,Password from user; use myblog; show tables;
  • Output of ls -la /var/www/html/wodpress/
  • Output of head -30 /var/www/html/wodpress/wp-config.php
  • Open a firefox with http://centos3/wordpress/
