selinux

1. Download and install the apache web server.

[root@localhost ~]# yum install httpd

2. Modify the /etc/httpd/conf/httpd.conf configuration file and replace /var/www/html with /content. Create the /content 
directory and then create a static index.html file in the /content directory that says "this is my website".

[root@localhost ~]# sed -i 's/\/var\/www\/html/\/content/' /etc/httpd/conf/httpd.conf

[root@localhost ~]# vim /etc/httpd/conf/httpd.conf then find and replace /var/www/html with /content

[root@localhost ~]# mkdir -p

[root@localhost ~]# echo "this is my website" > /content/index.html

3. Using sed, modify the /etc/httpd/conf.d/userdir.conf directory and replace UserDir disabled with UserDir public_html.

[root@localhost ~]# sed -i 's/disabled/public_html/' /etc/httpd/conf.d/userdir.conf 

or 

Manually modify the /etc/httpd/conf.d/userdir.conf

4. Create the public_html directory in the /home/user directory. Echo a simple html file with the text "this is my website" 
into the /home/user/public_html/index.html file.

 [root@localhost ~]# mkdir /home/user/public_html

[root@localhost ~]# echo "this is my website" > /home/user/public_html/index.html

5. Set the user owner and group owner of the /home/user directory to "user". Set permissions to 711 /home/user and 
755 recursively on /home/user/public_html.

[root@localhost ~]# chmod 711 /home/user

[root@localhost ~]# chmod 755 -R /home/user/public_html

[root@localhost ~]# chown user:user -R /home/user/public_html

6. Make the /content directory and restart the httpd service.

[root@localhost ~]# systemctl restart httpd

7.  Install the correct packages for troubleshooting SELinux policy denials and violations.

[root@localhost ~]# yum install -y setroubleshoot-server

8. Copy your IP address and attempt to open the index.html file in your browser. Troubleshoot using the proper SELinux 
troubleshooting package what may be causing the issue. Once you have determined the issue, implement a solution to fix 
the policy violation.

[root@localhost ~]# sealert -a /var/log/audit/audit.log 

[root@localhost ~]# semanage fcontext -a -t httpd_sys_content_t '/content(/.*)?'

[root@localhost ~]# restorecon -Rv /content

restorecon reset /content context unconfined_u:object_r:default_t:s0->unconfined_u:object_r:httpd_sys_content_t:s0

restorecon reset /content/index.html context unconfined_u:object_r:default_t:s0->unconfined_u:object_r:httpd_sys_content_t:s0

9. Attempt to open the user "user"'s homedir via the web browser. If permission is denied, troubleshoot the 
issue using the proper SELinux troubleshooting tools. Once the issue is discovered, implement a persistent fix and try again.

[root@localhost ~]# sealert -a /var/log/audit/audit.log

[root@localhost ~]# setsebool -P httpd_enable_homedirs on
