secondary ajp worker not working between apache and tomcat

Do you have SELinux on the system? Can you try:

setenforce 0

It could be preventing the apache process to connect. Also, check your firewall rules...

apache tomcat ajp

By default 8009 is opened by selinux, you can open more ports to use.

[goalin@centos63 logs]$ sudo semanage port -l | grep 8009

http_port_t tcp 80, 443, 488, 8008, 8009, 8443

[goalin@centos63 logs]$ sudo semanage port -a -t http_port_t -p tcp 18009

[goalin@centos63 logs]$ sudo semanage port -a -t http_port_t -p tcp 28009

[goalin@centos63 logs]$ sudo semanage port -l | grep 8009

http_port_t tcp 28009, 18009, 80, 443, 488, 8008, 8009, 8443

[goalin@centos63 logs]$
