# mod_cluster modules configuration

# See http://modcluster.io/ for docs, tutorials and examples

# Load mod_cluster modules

# Please, note:

#  - mod_cluster cannot coexist with proxy_balancer_module; disable it

#  - mod_cluster needs proxy_module and proxy_ajp_module loaded for AJP transport

# Uncomment to enable mod_cluster:

#LoadModule proxy_cluster_module modules/mod_proxy_cluster.so

#LoadModule cluster_slotmem_module modules/mod_cluster_slotmem.so

#LoadModule manager_module modules/mod_manager.so

#LoadModule advertise_module modules/mod_advertise.so

<IfModule manager_module>

  # Place for slotmem files - do not set this to NFS/CIFS

  MemManagerFile /var/cache/httpd/mod_cluster

  # We suggest to use a restricted VirtualHost

  # for receiving MCPM (Mod Cluster Protocol Message) from worker nodes.

  # To allow 6666 port for httpd, install policycoreutils-python-utils

  # and then label it:

  #

  #    semanage port -a -t http_port_t -p tcp 6666

  #

  # For UDP datagrams with httpd's location to be sent to UDP Multicast address, one might have

  # to allow it:

  #

  #    semanage port -a -t http_port_t -p udp 23364

  #

  # also Firewalld might need to know about it (depends on your network

  # domains and particular setup), example:

  #

  #    firewall-cmd --add-port=6666/tcp

  #    firewall-cmd --add-port=6666/tcp --permanent

  #

  #

  Listen 6666

  <VirtualHost *:6666>

    <Directory />

      # Change this to the range from which worker nodes are

      # going to contact the Apache HTTP Server,

      # e.g. your 10. internal network.

      Require ip 127.0.0.1

      # Worker nodes need to be contacted by Apache HTTP Server and also they

      # need to be able to initiate connections to Apache HTTP Server.

      # For example, if you have 2 workers reporting on your console

      # (see Management and monitoring console below) as:

      #

      #    
 Node worker-1 (ajp://192.168.122.138:8011): 

      #    
 Node worker-2 (ajp://192.168.122.138:8012): 

      #

      # you might need to label these ports for Selinux:

      #

      #    semanage port -a -t http_port_t -p tcp 8012

      #    semanage port -a -t http_port_t -p tcp 8011

      #

      # See aforementioned firewall-cmd for firewall settings.

    </Directory>

    # Apache HTTP Server advertises its presence

    # on 224.0.1.105:23364 via UDP multicast by default.

    # One has to allow this through Selinux:

    #

    #    semanage port -a -t http_port_t -p udp 23364

    #

    ServerAdvertise on

    # Here we declare that THIS and none other VirtualHost can

    # process configuration messages from worker nodes.

    EnableMCPMReceive

    # Management and monitoring console with the following default setup

    # appears on http://<your httpd address>:6666/mod_cluster_manager

    # and it is accessible only from localhost.
