Configure Aerospike Database

Overview​

This page describes how to configure a Database cluster node using the configuration file, aerospike.conf. The default location of the configuration file is /etc/aerospike/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. Prior to Aerospike Database 5.0, the line length limit was 256 characters.

Sample configuration file​

The following sample file shows the structure of aerospike.conf with the most common contexts and sub-contexts. The contexts is 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
}
info

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.
