The web server on your system can server all the existing HTML files from /var/www/html (NOTE: Do not make any changes to these files )

Web service should automatically start at boot time.

# semanage fcontext -a -t httpd_sys_content_t "/var/www/html(/.*)?"
# restorecon -Rv /var/www/html
# semanage port -l | grep http
# semanage port -a -t http_port_t -p tcp 82
# firewall-cmd --permanent --add-port=82/tcp
# firewall-cmd --reload

# useradd -G sysadms natasha

Verify the created user and its supplementary group

# id harry
# id nathasa

Create a user as named “sarah”, should have non-interactive shell and it should be not the member of “sysadms”.

# useradd -s /sbin/nologin sarah

# mkdir /home/manager
