RabbitMQ文件和目录位置
每个RabbitMQ节点使用许多文件和目录来加载配置;存储数据、元数据、日志文件等。文件和目录的位置可以改变。
文件系统权限
在更改文件或目录位置时，重要的是确保它们具有足够的权限，以便RabbitMQ节点OS进程可以从中读写。最好假设RabbitMQ使用的大多数目录和文件都需要读、写和文件创建权限。Debian、RPM和Windows安装程序脚本将设置适用于大多数环境的文件系统权限，但是，当系统范围内使用严格的默认权限时，可能需要在安装之后运行额外的配置步骤，以确保RabbitMQ节点文件和目录具有足够的权限。
指定位置
您可以设置以下环境变量来指定RabbitMQ应该在何处定位某些内容。在大多数环境中，默认值应该可以正常工作。
| Name | Description |
|---|---|
| RABBITMQ_BASE | This base directory contains sub-directories for the RabbitMQ server's database and log files. Alternatively, set RABBITMQ_MNESIA_BASE and RABBITMQ_LOG_BASE individually.这个基本目录包含RabbitMQ服务器的数据库和日志文件的子目录。或者，单独设置RABBITMQ_MNESIA_BASE和RABBITMQ_LOG_BASE。 |
| RABBITMQ_CONFIG_FILE | The path to the configuration file, without the .config extension. If the configuration file is present it is used by the server to configure RabbitMQ components. See Configuration guide for more information.配置文件的路径，没有.config扩展名。如果配置文件存在，服务器将使用它来配置RabbitMQ组件。默认值是${SYS_PREFIX}/etc/rabbitmq/rabbitmq |
| RABBITMQ_MNESIA_BASE | This base directory contains sub-directories for the RabbitMQ server's node database, message store and cluster state files, one for each node, unless RABBITMQ_MNESIA_DIR is set explicitly. It is important that effective RabbitMQ user has sufficient permissions to read, write and create files and subdirectories in this directory at any time.这个基本目录包含RabbitMQ服务器节点数据库、消息存储和集群状态文件的子目录，每个节点一个，除非显式设置RABBITMQ_MNESIA_DIR。重要的是，有效的RabbitMQ用户有足够的权限随时读写和创建该目录中的文件和子目录。默认值是${SYS_PREFIX}/var/lib/rabbitmq/mnesia |
| 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, unless RABBITMQ_LOGS or RABBITMQ_SASL_LOGS are set explicitly.默认值是${SYS_PREFIX}/var/log/rabbitmq |
| RABBITMQ_LOGS | The path of the RabbitMQ server's Erlang log file. This variable cannot be overridden on Windows. |
| RABBITMQ_SASL_LOGS | The path of the RabbitMQ server's Erlang SASL (System Application Support Libraries) log file. This variable cannot be overridden on Windows. |
| RABBITMQ_PLUGINS_DIR | The list of directories where plugins are found and loaded from. This is PATH-like variable, where different paths are separated by an OS-specific separator (: for Unix, ; for Windows). Plugins can be installed to any of the directories listed here.默认值是 "${RABBITMQ_HOME}/plugins" |
| RABBITMQ_PLUGINS_EXPAND_DIR | Working directory used to expand enabled plugins when starting the server. It is important that effective RabbitMQ user has sufficient permissions to read and create files and subdirectories in this directory.用于在启动服务器时展开启用插件的工作目录。重要的是，有效的RabbitMQ用户有足够的权限来读取和创建这个目录中的文件和子目录。 |
| RABBITMQ_ENABLED_PLUGINS_FILE | This file records explicitly enabled plugins. When a plugin is enabled or disabled, this file will be recreated. It is important that effective RabbitMQ user has sufficient permissions to read, write and create this file at any time.这个文件显式地记录了启用的插件。当插件被启用或禁用时，将重新创建该文件。重要的是，有效的RabbitMQ用户有足够的权限随时读取、写入和创建此文件。 |
| RABBITMQ_PID_FILE | File in which the process id is placed for use by rabbitmqctl wait.将进程id放置在其中以供rabbitmqctl等待使用的文件。 |
Unix系统默认位置
下表中${install_prefix}默认是/usr/local。Deb / RPM package installations use an empty ${install_prefix}.
