RabbitMQ的配置可以由三種方式進行定製。
環境變量
配置文件
運行時參數和策略
（1）環境變量：
定義端口、配置文件的位置（rabbitmq.config）和名值對（可以通過shell，也可以通過rabbitmq-env.conf）
rabbitmq-env.conf文件的位置是固定的${RabbitMQ-PREFIX}/etc/rabbitmq/rabbitmq-env.conf，不可改變。
rabbitmq-env.conf定義的變量會覆蓋rabbitmq啓動腳本的內置參數。
環境變量中的rabbitmq參數和rabbitmq-env.conf是一致的。（環境變量中的參數都有RABBITMQ_前綴）
#example rabbitmq-env.conf file entries #Rename the node NODENAME=bunny@myhost #Config file location and new filename bunnies.config CONFIG_FILE=/etc/rabbitmq/testdir/bunniesrabbitmq的變量優先級：
shell環境變量->rabbitmq-env.conf->內置變量值
| Name | Default | Description |
|---|---|---|
| RABBITMQ_NODE_IP_ADDRESS | the empty string - meaning bind to all network interfaces. | Change this if you only want to bind to one network interface. |
| RABBITMQ_NODE_PORT | 5672 | |
| RABBITMQ_NODENAME |
|
The node name should be unique per erlang-node-and-machine combination. To run multiple nodes, see theclustering guide. |
| RABBITMQ_SERVICENAME | Windows Service: RabbitMQ | The name of the installed service. This will appear in services.msc. |
| RABBITMQ_CONSOLE_LOG | Windows Service: |
Set this variable to new or reuse to
redirect console output from the server to a file named%RABBITMQ_SERVICENAME%.debug in the default RABBITMQ_BASE directory.
|
| RABBITMQ_CTL_ERL_ARGS | None | Parameters for the erl command used when invoking rabbitmqctl. This should be overridden for debugging purposes only. |
| RABBITMQ_SERVER_ERL_ARGS |
|
Standard parameters for the erlcommand used when invoking the RabbitMQ Server. This should be overridden for debugging purposes only. |
| RABBITMQ_SERVER_START_ARGS | None | Extra parameters for the erl command used when invoking the RabbitMQ Server. This will not overrideRABBITMQ_SERVER_ERL_ARGS. |
rabbitmq-env.conf還定義了一些列環境變量指出RabbitMQ的數據庫文件、日誌文件、插件、配置文件的地址。
| Name | Description |
|---|---|
| RABBITMQ_BASE | This base directory contains sub-directories for the RabbitMQ server's database and log files. Alternatively, set RABBITMQ_MNESIA_BASEand RABBITMQ_LOG_BASE individually. |
| RABBITMQ_CONFIG_FILE | The name of the configuration file, without the .config extension. If the configuration file is present it is used by the server to configure RabbitMQ components. This file is also used to auto-configure RabbitMQ clusters. |
| RABBITMQ_MNESIA_BASE | This base directory contains sub-directories for the RabbitMQ server's Mnesia database files, one for each node, unlessRABBITMQ_MNESIA_DIR is set explicitly. (In addition to Mnesia files this location also contains message storage and index files as well as schema and cluster details.) |
| RABBITMQ_MNESIA_DIR | The directory where this RabbitMQ node's Mnesia database files are placed. (In addition to Mnesia files this location also contains message storage and index files as well as schema and cluster details.) |
| RABBITMQ_LOG_BASE | This base directory contains the RabbitMQ server's log files, unlessRABBITMQ_LOGS or RABBITMQ_SASL_LOGS are set explicitly. |
| RABBITMQ_LOGS | The path of the RabbitMQ server's Erlang log file. This variable cannot be overridden on Windows. |
| RABBITMQ_SASL_LOGS | The path of the RabbitMQ server's Erlang SASL (System Application Support Libraries) log file. This variable cannot be overridden on Windows. |
| RABBITMQ_PLUGINS_DIR | The directory in which the plugins are found. |
| RABBITMQ_PLUGINS_EXPAND_DIR | Working directory used to expand enabled plugins when starting the server. |
| RABBITMQ_ENABLED_PLUGINS_FILE | This file records explicitly enabled plugins. |
| RABBITMQ_PID_FILE | File in which the process id is placed for use by rabbitmqctl wait. |
| Name | Location |
|---|---|
| RABBITMQ_BASE | (Not used) |
| RABBITMQ_CONFIG_FILE | $RABBITMQ_HOME/etc/rabbitmq/rabbitmq |
| RABBITMQ_MNESIA_BASE | $RABBITMQ_HOME/var/lib/rabbitmq/mnesia |
| RABBITMQ_MNESIA_DIR | $RABBITMQ_MNESIA_BASE/$RABBITMQ_NODENAME |
| RABBITMQ_LOG_BASE | $RABBITMQ_HOME/var/log/rabbitmq |
| RABBITMQ_LOGS | $RABBITMQ_LOG_BASE/$RABBITMQ_NODENAME.log |
| RABBITMQ_SASL_LOGS | $RABBITMQ_LOG_BASE/$RABBITMQ_NODENAME-sasl.log |
| RABBITMQ_PLUGINS_DIR | $RABBITMQ_HOME/plugins |
| RABBITMQ_PLUGINS_EXPAND_DIR | $RABBITMQ_MNESIA_BASE/$RABBITMQ_NODENAME-plugins-expand |
| RABBITMQ_ENABLED_PLUGINS_FILE | $RABBITMQ_HOME/etc/rabbitmq/enabled_plugins |
| RABBITMQ_PID_FILE | $RABBITMQ_MNESIA_DIR.pid |
