Reference

MemManagerFile

MemManagerFile is the directory mod_manager will use to store configuration, generate keys for shared memory or lock files. It must be an absolute path name. If the directory does not exist, it will be automatically created. The default value is $server_root/logs/.

Important

It is highly recommended that the directory lives on a local drive and not an NFS share.

Possible Improvement

Locating operational files that are not log files in $server_root/logs/ is counterintuitive. mod_cluster should be configured to write those files in /etc/httpd/run.

ManagerBalancerName

The name for the balancer when the backend nodes do not provide a balancer name. The default value is mycluster.

PersistSlots

When set to "on", nodes, aliases and contexts are persisted in files. The default value is "off".

For more details related to PersistSlots, see mod_cluster Concepts - PeristSlots.

Example:

<IfModule manager_module>
  ...
  PersistSlots on
  ...
</IfModule>
