Can you provide SELinux examples?

Sure! Here are a few basic examples related to SELinux:

1. Check Current SELinux Status

To check if SELinux is enabled and its current mode:

sestatus

2. Change SELinux Mode Temporarily

To set SELinux to permissive mode (for testing):

setenforce 0

To revert back to enforcing mode:

setenforce 1

3. List SELinux Contexts

To list the SELinux context of a file:

ls -Z /path/to/file

4. Change File Context

To change the context of a file to httpd_sys_content_t:

chcon -t httpd_sys_content_t /var/www/html/index.html

5. View SELinux Audit Logs

To view SELinux denials and audit logs:

ausearch -m avc -ts recent

6. Restore Default Contexts

To restore the default SELinux context for files in a directory:

restorecon -Rv /var/www/html

These commands can help you manage and troubleshoot SELinux settings. If you need more specific examples or explanations, let me know!
