rabbitmq启动报错
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.
systemctl start rabbitmq-server
journalctl -xe
原因
Linux的主机名有问题，不能出现数字
解决
hostname 查看主机名，这里是虚拟机ip
vim /etc/hosts 修改hosts文件
测试
systemctl start rabbitmq-server
注意：重启centos，修改才生效
sudo shutdown -r now
