 Account server configuration

Find an example account server configuration at etc/account-server.conf-sample in the source code repository.

The available configuration options are:

Table 11.38. Description of configuration options for [DEFAULT] in account-server.conf
Configuration option = Default value Description
backlog = 4096 Maximum number of allowed pending TCP connections
bind_ip = 0.0.0.0 IP Address for server to bind to
bind_port = 6002 Port for server to bind to
bind_timeout = 30 Seconds to attempt bind before giving up
db_preallocation = off If you don't mind the extra disk space usage in overhead, you can turn this on to preallocate disk space with SQLite databases to decrease fragmentation. underlying filesystem does not support it. to setup custom log handlers. bytes you'd like fallocate to reserve, whether there is space for the given file size or not. This is useful for systems that behave badly when they completely run out of space; you can make the services pretend they're out of space early. server. For most cases, this should be `egg:swift#account`. replication passes account can be reclaimed
devices = /srv/node Parent directory of where devices are mounted
disable_fallocate = false Disable "fast fail" fallocate checks if the underlying filesystem does not support it.
eventlet_debug = false If true, turn on debug logging for eventlet
fallocate_reserve = 0 You can set fallocate_reserve to the number of bytes you'd like fallocate to reserve, whether there is space for the given file size or not. This is useful for systems that behave badly when they completely run out of space; you can make the services pretend they're out of space early. server. For most cases, this should be `egg:swift#object`.
log_address = /dev/log Location where syslog sends the logs to
log_custom_handlers = Comma-separated list of functions to call to setup custom log handlers.
log_facility = LOG_LOCAL0 Syslog log facility
log_level = INFO Logging level
log_max_line_length = 0 Caps the length of log lines to the value given; no limit if set to 0, the default.
log_name = swift Label used when logging
log_statsd_default_sample_rate = 1.0 Defines the probability of sending a sample for any given event or timing measurement.
log_statsd_host = localhost If not set, the StatsD feature is disabled.
log_statsd_metric_prefix = Value will be prepended to every metric sent to the StatsD server.
log_statsd_port = 8125 Port value for the StatsD server.
log_statsd_sample_rate_factor = 1.0 Not recommended to set this to a value less than 1.0, if frequency of logging is too high, tune the log_statsd_default_sample_rate instead.
log_udp_host = If not set, the UDP receiver for syslog is disabled.
log_udp_port = 514 Port value for UDP receiver, if enabled.
max_clients = 1024 Maximum number of clients one worker can process simultaneously Lowering the number of clients handled per worker, and raising the number of workers can lessen the impact that a CPU intensive, or blocking, request can have on other requests served by the same worker. If the maximum number of clients is set to one, then a given worker will not perform another call while processing, allowing other workers a chance to process it.
mount_check = true Whether or not check if the devices are mounted to prevent accidentally writing to the root device
swift_dir = /etc/swift Swift configuration directory
user = swift User to run as
workers = auto a much higher value, one can reduce the impact of slow file system operations in one request from negatively impacting other requests.

Table 11.39. Description of configuration options for [app-account-server] in account-server.conf
Configuration option = Default value Description
auto_create_account_prefix = . Prefix to use when automatically creating accounts
replication_server = false If defined, tells server how to handle replication verbs in requests. When set to True (or 1), only replication verbs will be accepted. When set to False, replication verbs will be rejected. When undefined, server will accept any verb in the request.
set log_address = /dev/log Location where syslog sends the logs to
set log_facility = LOG_LOCAL0 Syslog log facility
set log_level = INFO Log level
set log_name = account-server Label to use when logging
set log_requests = true Whether or not to log requests
use = egg:swift#account Entry point of paste.deploy in the server

Table 11.41. Description of configuration options for [account-replicator] in account-server.conf

log_facility = LOG_LOCAL0 Syslog log facility
log_level = INFO Logging level
log_name = account-replicator Label used when logging
max_diffs = 100 Caps how long the replicator spends trying to sync a database per pass
node_timeout = 10 Request timeout to external services

Table 11.42. Description of configuration options for [account-auditor] in account-server.conf

interval = 1800 Minimum time for a pass to take
log_address = /dev/log Location where syslog sends the logs to
log_facility = LOG_LOCAL0 Syslog log facility
log_level = INFO Logging level

Table 11.43. Description of configuration options for [account-reaper] in account-server.conf
Configuration option = Default value Description
concurrency = 25 Number of replication workers to spawn
conn_timeout = 0.5 Connection timeout to external services
delay_reaping = 0 Normally, the reaper begins deleting account information for deleted accounts immediately; you can set this to delay its work however. The value is in seconds, 2592000 = 30 days, for example. bind to giving up worker can process simultaneously (it will actually accept(2) N + 1). Setting this to one (1) will only handle one request at a time, without accepting another request concurrently. By increasing the number of workers to a much higher value, one can reduce the impact of slow file system operations in one request from negatively impacting other requests.
interval = 3600 Minimum time for a pass to take
log_address = /dev/log Location where syslog sends the logs to
log_facility = LOG_LOCAL0 Syslog log facility
log_level = INFO Logging level
log_name = account-reaper Label used when logging
node_timeout = 10 Request timeout to external services
reap_warn_after = 2592000 No help text available for this option.
