当我通过以下命令在突触中安装 rabbitMQ 时
sudo apt-get install rabbitmq-server
它返回一个错误：
Starting rabbitmq-server: FAILED - check /var/log/rabbitmq/startup_log, _err
rabbitmq-server.
invoke-rc.d: initscript rabbitmq-server, action "start" failed.
dpkg: error processing rabbitmq-server (--configure):
subprocess installed post-installation script returned error exit status 1
Errors were encountered while processing:
rabbitmq-server
E: Sub-process /usr/bin/dpkg returned an error code (1)
转到日志，它说以下内容：
Error: {cannot_connect_to_epmd,"herman-desktop",address}
而我/etc/hosts的定义如下：
127.0.0.1 localhost.localdomain localhost
::1 herman-desktop localhost6.localdomain6 localhost6
127.0.1.1 herman-desktop
我需要做什么来解决这个问题？
