Configure Aerospike Database

Aerospike uses a single file to configure a database node. 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 Server 5.0, the line length limit was 256 characters.)

The following example shows the structure of aerospike.conf, with the most common contexts and sub-contexts. The contexts shown below 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 {}           # Configure persistence or lack of persistence
    set {}               # (Optional) Set specific record policies
}

mod-lua {                # location of UDF modules
}

The following aerospike.conf is the default configuration that ships with Aerospike. When you install a new Aerospike instance, you will have a running instance without any modifications. This is sufficient for testing, but for a production system you will probably need to make changes. Refer to the sections following this example to learn more. 

 # 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

}
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. (Optional) Configure feature key.
  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.
