- 查看是否存在文件夹
ls -ld /home/rabbitmq
- 没有就创建
sudo mkdir -p /home/rabbitmq - 授予权限
sudo chown -R rabbitmq:rabbitmq /home/rabbitmq
重启后出现新的问题
[root@localhost home]# systemctl status rabbitmq -l

解决办法：
- 设置权限
sudo chown -R rabbitmq:rabbitmq /usr/local/dhtech/rabbitmq/var/lib/rabbitmq/mnesia
sudo chmod -R 755 /usr/local/dhtech/rabbitmq/var/lib/rabbitmq/mnesia
重启
sudo systemctl start rabbitmq
systemctl status rabbitmq -l
至此Rabbit MQ正常启动
[root@localhost home]# systemctl status rabbitmq -l
