RabbitMQ配置文件

配置文件Config

在Web的可视化管理界面中可以看到一些文件的路径

比如

Config文件的地址

数据库存放的文件夹

log文件的地址

进入到这个文件夹会发现有这些文件，其中example是config的示例文件，事实上config文件是空的，我们需要从示例文件中拷贝代码到config中

下面是示例文件的全部内容，其中有一些需要我们关注的

tcp_listeners 端口设置，这里默认的是5672。这边还提供了另一种设置方法

{tcp_listeners, [5672]}

{tcp_listeners, [{"127.0.0.1", 5672}, %% {"::1", 5672}]}

日志输出级别设置，默认是info。这会产生大量的无用日志，甚至可以把硬盘挤爆，所以设置成error级别就好

{log_levels, [{connection, error}, {channel, error}]}

内存占用设置,可以根据百分比设置，也可以根据G、 M、Kb去设置，当超出时会让connection blocked

{vm_memory_high_watermark, 0.4}

硬盘占用设置，和内存相同，在压力较大时也会connection blocked

{vm_memory_high_watermark, 0.4}

config里还有很多重要的设置，比如默认的vhost、 user。当然现在一一去说的话会让人感到莫名所以，因为我们才刚开始接触到RabbitMQ。所以在后面的学习中再一一讲解

[{rabbit,[%%%% Network Connectivity%% ====================%%%% By default, RabbitMQ will listen on all interfaces, using%% the standard (reserved) AMQP port.%%%% {tcp_listeners, [5672]},%% To listen on a specific interface, provide a tuple of {IpAddress, Port}.%% For example, to listen only on localhost for both IPv4 and IPv6:%%%% {tcp_listeners, [{"127.0.0.1", 5672},%%                  {"::1",       5672}]},%% SSL listeners are configured in the same fashion as TCP listeners,%% including the option to control the choice of interface.%%%% {ssl_listeners, [5671]},%% Number of Erlang processes that will accept connections for the TCP%% and SSL listeners.%%%% {num_tcp_acceptors, 10},%% {num_ssl_acceptors, 1},%% Maximum time for AMQP 0-8/0-9/0-9-1 handshake (after socket connection%% and SSL handshake), in milliseconds.%%%% {handshake_timeout, 10000},%% Log levels (currently just used for connection logging).%% One of 'debug', 'info', 'warning', 'error' or 'none', in decreasing%% order of verbosity.
