RabbitMQ启动报错，journalctl日志：Error parsing configuration
ubuntu 22.04 系统,运行RabbitMQ启动命令"service rabbitmq-server start"时出错，提示如下：root@mq00b34:~# service rabbitmq-server start
Job for rabbitmq-server.service failed because the control process exited with error code.
See "systemctl status rabbitmq-server.service" and "journalctl -xeu rabbitmq-server.service" for details.
root@mq00b34:~# ^C
根据提示，执行了 journalctl -xe ，定位到详细的报错日志信息；journalctl -xe
通过这个执行到命令行后，会打印出非常多的问题信息，让我们继续往下定位到ERROR处：Feb 08 13:51:47 mq00b34 rabbitmq-server: Configuring logger redirection

通过以上错误信息，检查 /etc/rabbitmq/rabbitmq.conf 配置文件有没有错误，发现abbitmq.conf文件权限为640，把权限改为644，再次启动服务，一切正常。
