RabbitMQ 日志管理

##日志默认输出位置

如果我们是通过rpm方式进行安装的，那么系统默认会把日志放在/var/log/rabbitmq/目录下

日志说明

在日志目录/var/log/rabbitmq目录下，默认会有两类日志文件，一个是rabbit@{hostname}.log，另一个是rabbit@{hostname}-sasl.log。

• rabbit@{hostname}.log：输出rabbitmq运行相关的信息，如网络流量，用户，交换器，队列等信息。
• rabbit@{hostname}-sasl.log：Erlang运行相关信息。

日志样例

rabbit@{hostname}.log

rabbit@{hostname}-sasl.log

如果运行了rabbitmq集群或者rabbitmq依赖的erlang操作报错，这个文件才会有输出信息。后面再补充样例数据。
