About this Hands-on Lab

This hands-on lab allows you to practice troubleshooting and resolving SELinux filesystem context issues. Being able to discover and resolve SELinux context issues is a key concept when working with SELinux. At the end of this activity, you will understand how to view and apply new security contexts to files and directories.

Learning Objectives

Successfully complete this lab by achieving the following learning objectives:

Check the Directory and Index File Security Context

Compare the SELinux security context of /var/www/html to the /var/www/html/web-api directory to determine if the context of the new directory and its contents need to be adjusted:

  • View the context of the html directory by running ls -Z /var/www.
  • View the context of the web-api directory by running ls -Z /var/www/html/web-api.
Restore the Appropriate Security Context to the API Directory
  • Restore the context of the files and directories in the web /var/www/html directory by running sudo restorecon -R /var/www/html/web-api.
  • View the updated context by running ls -Z /var/www/html/web-api.
  • Verify that the update is working by running curl localhost/web-api/index.html.
