There are two main commands used to set the SELinux security context of files:
You can reset the default security context of the entire system at the next boot with this command:
# Start the MySQL service (mysqld).
# '''When started for the first time, this service will print a message telling 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.
# Configure this software to start when the system is booted.
# Configure httpd to serve the <code>~/public_html</code> directories of your users. This will require changes to <code>/etc/httpd/conf/httpd.conf</code> as well as the SELinux configuration. See the man page for <code>httpd_selinux</code> and the Apache [http://httpd.apache.org/docs/2.2/ httpd documentation] for details.
# Prove that this works by creating a page in your <code>~/public_html</code> directory.The URL will be <code>http://''hostname''/~''your-user-id''/</code># Create a short web script which displays the available disk space on the computer. At its most basic level, a web script is the same as a regular script, with this additional requirement:#* It must output the line "Content-type: text/plain" or "Content-type: text/html" (depending on whether the script output is plain text or HTML), followed by a blank line.# Name the script <code>~/public_html/diskfree.cgi</code> - The URL will be <code>http://''hostname''/~''your-user-id''/diskfree.cfgi</code># Configure httpd and SELinux to allow your script to be run from the web. This will require changes to <code>/etc/httpd/conf/httpd.conf</code> as well as the SELinux configuration (possibly including both booleans and SELinux context). As with step 1, see the man page for <code>httpd_selinux</code> and the Apache [http://httpd.apache.org/docs/2.2/ httpd documentation] for details. {{Admon/tip|Hint|Look for an "add-handler" line in your httpd.conf file.}}
== Write-up ==
Create a write-up of this assignment on your wiki. Include at least these pages:
# A main page, describing in general terms what you did and containing links to the other wiki pages, as well as a link to the page in your <code>~/public_html</code> directory.
# A page for your httpd configuration. Include the exact text of your httpd.conf file.# A page for your MySQL configuration. Include the details of the steps you performed to set up MySQL.
# A page for your SELinux configuration. Include a list of all of your booleans and their current settings. Demonstrate that the configuration is as tight as possible (e.g., don't change booleans unnecessarily).
# A page for your MediaWiki configuration. Include your MediaWiki configuration file.
The easiest way to create new page is to create a link to it from an existing page (such as the main page), and then follow that link.
