{{Admon/important|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.}}<br> == 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 as well as the your '''iptables firewall''' to further enhance the security of your computer system.
'''NOTE: Do this assignment inside the centos3 virtual machine. '''

== Installing Packages==
<u>Install these packages using ''yum''</u>
:*Download a "zipped tar-ball" from a website (google-search), decompress, and compile
== Configuring Apache ==
# Start the httpd service using '''systemctl'''.
# Ensure that the httpd service starts automatically during boot.
# Confirm that you can connect to your web server using a web browser -- both from centos3 (you can test using '''linkslynx''') as well as from the host. You should see the Apache Test Page.
# If you can't connect to it from outside the machine - perhaps your firewall is blocking access to the web server.
== Configuring MySQL ==
# Start the MySQL service (mysqld or mariadb) using '''systemctl'''.
#* 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.
# Set your MySQL root password to your learn ID Seneca e-mail username (without the ''@senecac.onmyseneca.ca '' part).
# 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:
## '''NOTE: If you decide to download the wordpress package during this section, please use the 5.0.x version here (use wget): https://wordpress.org/wordpress-5.0.7.tar.gz'''## Start by looking at httphttps://codex.wordpress.org/Installing_WordPresssupport/article/creating-database-for-wordpress/#Using_the_MySQL_Client using-the-mysql-client where you will find instructions for the setup.
## You will need to run those commands in a centos3 terminal.
## Your adminusername is root
## Your databasename is myblog
## Your wordpressusername is your learn IDSeneca username## The password should also be your learn IDSeneca username
## 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.
# '''Download the latest 5.tar0.gz x version from wodpress.org into of wordpress to your centos3 VM here (use wget): https://wordpress.org/wordpress-5.0.7.tar.gz'''
# Extract it into '''/var/www/html'''
# Now we need to allow Apache to modify the wordpress installation. To do this use <b>chown</b> and <b>chgrp</b> with <b>-R</b> option to make the owner and group of every file and directory inside wordpress "apache".
# 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"
# 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.'''(Do not use the root account for your database connection! Marks will be deducted.)'''
# 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 "OPS235 Professor's Blog"
#* Click "Install Wordpress", you should see a "Success!" message.
== Write-up ==
Write a blog post on your new blog explaining:
* What problems (minor and major) you ran into during the installation and how you solved them.
Write a second post on your blog explainingincluding for example:
* Are you ready for the exam or not.
* List the material you are strong on.
''' Make your posts look professional. That means use good english, headings, bullet or numbered lists, etc.
== Submitting Your Assignment == '''Due date:''' Check with your professor for the due dates on this assignment and how they choose to mark it. Assignments submitted after the due date will receive a grade of 0, but must still be completed satisfactorily in order to pass the course.
'''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.== Online Submission Requirements ==
