The ecelerity-cluster.conf file is a cluster-specific configuration file that configures cluster behavior. This file is typically used to specify options common to all nodes, e.g. the cluster topology. It is included from within ecelerity.conf.

The following is an example ecelerity-cluster.conf file:

# Security stanza
# Ensure that you have appropriate privileges
Security {
  user = "ecuser"
  group = "ecuser"
  Capabilities = "cap_net_admin+ep cap_net_bind_service+ep cap_net_raw+ep cap_sys_resource+ep"

# Aggregated cluster node logging
ec_logger "ec_logger_cluster" {
  mainlog = "cluster:///var/log/ecelerity/mainlog.cluster=>master"
  paniclog = "cluster:///var/log/ecelerity/paniclog.cluster=>master"
  rejectlog = "cluster:///var/log/ecelerity/rejectlog.cluster=>master"
  acctlog = "cluster:///var/log/ecelerity/acctlog.cluster=>master"

bounce_logger "bounce_logger_cluster" {
  bouncelog = "cluster:///var/log/ecelerity/bouncelog.cluster=>master"

# ECCluster_Listener stanza
ECCluster_Listener {
  Listen "*:4802" {}

# Cluster module
cluster {
  cluster_group = "ec_cluster"
  control_group = "ec_console"
  logs = [
    rejectlog = "/var/log/ecelerity/rejectlog.cluster"
    paniclog = "/var/log/ecelerity/paniclog.cluster"
    mainlog = "/var/log/ecelerity/mainlog.cluster"
    acctlog = "/var/log/ecelerity/acctlog.cluster"
    bouncelog = "/var/log/ecelerity/bouncelog.cluster"
  Replicate "inbound_cidr" {}
  Replicate "outbound_cidr" {}
  Replicate "outbound_domains" {}
  Replicate "outbound_binding_domains" {}
  Replicate "shared_named_throttles" {}

  # DuraVIP network topology hints
  Topology "" {
    cidrmask = "32"
    interface = "eth1"


IPv6 addresses are much more flexible than IPv4 addresses in terms of their formatting options. They also use a different delimiter character than IPv4 addresses (a colon instead of a period). This means that in certain contexts, an IPv6 address can create parsing ambiguities.

The accepted convention is to require that, in circumstances where a configuration parameter can also contain something other than an IP address, that an IPv6 address must be enclosed in square brackets. In practical terms, this means that things like the Gateway, Routes and Listen options must have IPv6 addresses enclosed in brackets. Others, such as Peer, Relay_Hosts and Prohibited_Hosts do not require the IPv6 address in brackets.

You cannot view the contents of the ecelerity-cluster.conf file using the console from the cluster manager. You can only view the contents of this file from a cluster node because it is included from the ecelerity.conf file.

For a discussion of scopes and fallbacks, see “Configuration Scopes and Fallback”.

For a summary of all the non-module specific configuration options, refer to Configuration Options Summary .

Modules and their configuration options are discussed in the Modules Reference .

The following sections provide an overview of the configuration commonly defined in the ecelerity-cluster.conf file.


The definition of the Security stanza in the ecelerity-cluster.conf file applies to the cluster nodes only and usually differs from the configuration found in the eccluster.conf file.

For a discussion of the Security stanza options, see security.


For a discussion of the ECCluster_Listener stanza, see “ECCluster_Listener Configuration”.

Aggregated Cluster Node Logging

For a discussion of using the ec_logger module in aggregated logging, see “Configuration of Aggregated Cluster Node Logging”.

For a discussion of using the bounce_logger module in aggregated logging, see “Configuration of Aggregated Cluster Node Logging”.
