Configure Aerospike Database

This page describes how to configure a Database cluster node using the configuration file, aerospike.conf.

The configuration file is divided into different contexts, some of which are optional. These contexts can be in any order in the configuration file. A context can be further divided into sub-contexts. The maximum length of a line in the configuration file is 1,024 characters. The default location of the configuration file is /etc/aerospike/aerospike.conf.

Sample configuration file

The following sample file shows the structure of aerospike.conf with the most common contexts and sub-contexts. The contexts in this example are empty and do not have actual parameters, indicated by empty braces {}. Sub-contexts are indented.

Caution

This is not a working configuration example. Do not copy and try to use it as-is. It will not work without adding your parameters.

service {}               # Tuning parameters, process owner, feature
                         # key file

network {                # Used to configure intracluster and
                         # application-node communications
    service {}           # Tools/Application communications protocol
    fabric {}            # Intracluster communications protocol
    info {}              # Administrator telnet console protocol
    heartbeat {}         # Cluster formation protocol
}

security {               # (Optional, Enterprise Edition only) to enable
                         # access control on the cluster
}

logging {}               # Logging configuration

xdr {                    # (Optional, Enterprise Edition only) Configure
                         # Cross-Datacenter Replication
}

namespace {              # Define namespace record policies and storage
                         # engine
    storage-engine {}    # Configure data storage for the namespace
    set {}               # (Optional) Set specific record policies
}

mod-lua {                # location of UDF modules
}

Configuration file changes

The following examples show how aerospike.conf changed in Database 7.0.

Database 7.0 and later

# Aerospike database developer configuration file.

service {
  run-as-daemon false # To work with gdb, and make console logging visible.

  # The number of concurrent connections to the database is limited by
  # proto-fd-max, and by the system's maximum number of open file descriptors.
  # See "man limits.conf" for how to set the system's "nofile" limit.
  proto-fd-max 1024

  work-directory run/work
  pidfile run/asd.pid
  cluster-name cakery
}

mod-lua {
  user-path run/work/usr/udf/lua
}

logging {
  # Log file must be an absolute path.
  file run/log/aerospike.log {
    context any info
  }

  console {
    context any info
  }
}

network {
  service {
    address any
    port 3000
  }

  heartbeat {
    mode multicast
    multicast-group 239.1.99.222
    port 9918

    # To use unicast-mesh heartbeats, remove the 3 lines above, and see
    # aerospike_mesh.conf for alternative.

    interval 150
    timeout 10
  }

  fabric {
    port 3001
  }

#  info {
#    port 3003
#  }
}

namespace test {
  replication-factor 2

  storage-engine memory {
    data-size 4G
  }
}

Prior to Database 7.0

 # Aerospike database configuration file.

service {
  user root
  group root
  pidfile /var/run/aerospike/asd.pid
  proto-fd-max 15000
}

logging {
  # Log file must be an absolute path.
  file /var/log/aerospike/aerospike.log {
    context any info
  }
}

network {
  service {
    address any
    port 3000
  }

  heartbeat {
    mode multicast
    multicast-group 239.1.99.222
    port 9918

    # To use unicast-mesh heartbeats, remove the 3 lines above, and see
    # aerospike_mesh.conf for alternative.

    interval 150
    timeout 10
  }

  fabric {
    port 3001
  }

  info {
    port 3003
  }
}

namespace test {
  replication-factor 2
  memory-size 4G

  storage-engine memory
}

Note

You can use any port between 1024 and 65335 for Aerospike, as long as the port is not in use by an existing process.

Configuration steps

1. (If necessary) Obtain a feature-key file.
2. Configure network service and heartbeat sub-contexts.
3. Configure namespaces.
4. Configuring Log Files and Manually Rotating the Aerospike Log File.
5. (Optional) Configure security.
6. (Optional) Configure rack-awareness.
7. (Optional) Configure cross-datacenter replication.
