队列模式环境变量#

基于文件的配置

您可以为单个变量添加_FILE，以便在单独的文件中提供其配置。详情请参阅将敏感数据保存在单独文件中。

您可以根据需求以不同模式运行n8n。队列模式提供最佳的可扩展性。更多信息请参阅队列模式。

变量	类型	默认值	描述
`QUEUE_BULL_PREFIX`	String	-	Prefix to use for all queue keys.
`QUEUE_BULL_REDIS_DB`	Number	`0`	The Redis database used.
`QUEUE_BULL_REDIS_HOST`	String	`localhost`	The Redis host.
`QUEUE_BULL_REDIS_PORT`	Number	`6379`	The Redis port used.
`QUEUE_BULL_REDIS_USERNAME`	String	-	The Redis username (needs Redis version 6 or above). Don't define it for Redis < 6 compatibility
`QUEUE_BULL_REDIS_PASSWORD`	String	-	The Redis password.
`QUEUE_BULL_REDIS_TIMEOUT_THRESHOLD`	Number	`10000`	The Redis timeout threshold (in ms).
`QUEUE_BULL_REDIS_CLUSTER_NODES`	String	-	Expects a comma-separated list of Redis Cluster nodes in the format `host:port`, for the Redis client to initially connect to. If running in queue mode (`EXECUTIONS_MODE = queue`), setting this variable will create a Redis Cluster client instead of a Redis client, and n8n will ignore `QUEUE_BULL_REDIS_HOST` and `QUEUE_BULL_REDIS_PORT`.
`QUEUE_BULL_REDIS_TLS`	Boolean	`false`	Enable TLS on Redis connections.
`QUEUE_BULL_REDIS_DUALSTACK`	Boolean	`false`	Enable dual-stack support (IPv4 and IPv6) on Redis connections.
`QUEUE_WORKER_TIMEOUT` (deprecated)	Number	`30`	Deprecated Use `N8N_GRACEFUL_SHUTDOWN_TIMEOUT` instead. How long should n8n wait (seconds) for running executions before exiting worker process on shutdown.
`QUEUE_HEALTH_CHECK_ACTIVE`	Boolean	`false`	Whether to enable health checks (true) or disable (false).
`QUEUE_HEALTH_CHECK_PORT`	Number	-	The port to serve health checks on.
`QUEUE_WORKER_LOCK_DURATION`	Number	`30000`	How long (in ms) is the lease period for a worker to work on a message.
`QUEUE_WORKER_LOCK_RENEW_TIME`	Number	`15000`	How frequently (in ms) should a worker renew the lease time.
`QUEUE_WORKER_STALLED_INTERVAL`	Number	`30000`	How often should a worker check for stalled jobs (use 0 for never).
`QUEUE_WORKER_MAX_STALLED_COUNT`	Number	`1`	Maximum amount of times a stalled job will be re-processed.

变量	类型	默认值	描述
`N8N_MULTI_MAIN_SETUP_ENABLED`	Boolean	`false`	Whether to enable multi-main setup for queue mode (license required).
`N8N_MULTI_MAIN_SETUP_KEY_TTL`	Number	`10`	Time to live (in seconds) for leader key in multi-main setup.
`N8N_MULTI_MAIN_SETUP_CHECK_INTERVAL`	Number	`3`	Interval (in seconds) for leader check in multi-main setup.
