We also needed to install XML::Simple, see http://search.cpan.org/dist/XML-Simple/lib/XML/Simple/FAQ.pod#How_do_I_install_XML::Simple?

Also need to start Apache

• telnet ping02 80 from pinger showed it was not open.

• If you just want to start apache, after downloading it you can run:
  sudo systemctl enable httpd
  sudo systemctl start httpd 

  Code Block

  [root@ping02 pinger-2.0.7]# systemctl enable httpd #This command ensures apache starts after a reboot Created symlink from /etc/systemd/system/multi-user.target.wants/httpd.service to /usr/lib/systemd/system/httpd.service. [root@ping02 pinger-2.0.7]# systemctl start httpd #Starts Apache immediately. You can replace start with restart [root@ping02 pinger-2.0.7]# ps -efl | grep httpd 4 S root 33322 1 0 80 0 - 55488 poll_s 09:20 ? 00:00:00 /usr/sbin/httpd -DFOREGROUND 5 S apache 33323 33322 0 80 0 - 58550 inet_c 09:20 ? 00:00:00 /usr/sbin/httpd -DFOREGROUND 5 S apache 33324 33322 0 80 0 - 58550 inet_c 09:20 ? 00:00:00 /usr/sbin/httpd -DFOREGROUND 5 S apache 33325 33322 0 80 0 - 58550 inet_c 09:20 ? 00:00:00 /usr/sbin/httpd -DFOREGROUND 5 S apache 33326 33322 0 80 0 - 58550 inet_c 09:20 ? 00:00:00 /usr/sbin/httpd -DFOREGROUND 5 S apache 33327 33322 0 80 0 - 58550 inet_c 09:20 ? 00:00:00 /usr/sbin/httpd -DFOREGROUND 0 S root 33334 31095 0 80 0 - 28165 pipe_w 09:23 pts/0 00:00:00 grep --color=auto httpd
