当重启服务器后，用使用 systemctl start rabbitmq-server.service 命令启动报错：

错误信息：Job for rabbitmq-server.service failed because the control process exited with error code. See "systemctl status rabbitmq-server.service" and "journalctl -xe" for details.

解决方法：

1. 创建配置文件

// 跳转目录
cd /etc/rabbitmq/
// 创建文件
vim rabbitmq-env.conf

2. 添加内容

NODENAME=rabbit@localhost

保存后再次启动 RabbitMQ，问题解决。
