AMQP 消息服务器，RabbitMQ 3.5.7.RC1 发布

jopen 10年前

RabbitMQ 是由 LShift 提供的一个 Advanced Message Queuing Protocol (AMQP) 的开源实现，由以高性能、健壮以及可伸缩性出名的 Erlang 写成，因此也是继承了这些优点。

AMQP 里主要要说两个组件：Exchange 和 Queue （在 AMQP 1.0 里还会有变动），如下图所示，绿色的 X 就是 Exchange ，红色的是 Queue ，这两者都在 Server 端，又称作 Broker ，这部分是 RabbitMQ 实现的，而蓝色的则是客户端，通常有 Producer 和 Consumer 两种类型：

更新内容

服务器

Bug 修复

  • file_handle_cache:clear_read_cache/0 no longer silently fails.

    The function is mean to be used with rabbitmqctl eval in environments where
    in-process buffering of file data is enabled.

    GitHub issue: rabbitmq-server#436

  • Default RABBITMQ_PLUGINS_DIR value on Windows should be calculated as relative to RabbitMQ
    server installation directory, not RABBITMQ_BASE.

    If you override RABBITMQ_BASE, you may need to copy plugins from %RABBITMQ_BASE%\plugins
    to the plugins directory under RabbitMQ installation.

    GitHub issue: rabbitmq-server#433

  • Overriding RABBITMQ_LOGS and RABBITMQ_SASL_LOGS on Windows prevented node from starting.

    GitHub issue: rabbitmq-server#375

  • Some startup code bits assumed IPv4 is enabled in the environment

    GitHub issue: rabbitmq-server#117

  • More robust disk monitor, fewer errors logged.

    GitHub issue: rabbitmq-server#91

改进

  • RAM watermark can be configured as an absolute value in bytes (just like with disk space monitoring):

    ?
    1
    [{rabbit, [{vm_memory_high_watermark, {absolute,  1073741824 }}]}].

    GitHub issue: rabbitmq-server#207

  • rabbitmqctl authenticate_user is a new command that can be used to test user authentication.

    GitHub issue: rabbitmq-server#119

  • rabbitmqctl now supports exclusive as a queue info item.
