1.背景描述

在创建rabbitmq集群时，需要将当前节点的.erlang.cookie文件数据修改为第一个节点的.erlang.cookie文件内容，这里为了防止手动vim修改导致数据末尾的自动换行符的引入，我使用了文件的直接替换，随后在重启当前的mq节点服务时，报错如下：

[root@net-test-leel ~]# service rabbitmq-server restart
Redirecting to /bin/systemctl restart rabbitmq-server.service
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.

结果就是rabbitmq启动失败

[root@net-test-leel ~ rabbitmq]# service rabbitmq-server status
Redirecting to /bin/systemctl status rabbitmq-server.service
● rabbitmq-server.service - RabbitMQ broker
   Loaded: loaded (/usr/lib/systemd/system/rabbitmq-server.service; disabled; vendor preset: disabled)

随后，执行reset时报错

[error] Cookie file /var/lib/rabbitmq/.erlang.cookie must be accessible by owner only

2：问题解决

报错的内容是权限问题，当前这个文件只能文件的所有者才能访问，因为这个文件是从其他节点上复制并替换的，所以需要重新赋予权限，在rabbitmq的默认安装路径/var/lib/rabbitmq/下执行如下命令，

sudo chown rabbitmq:rabbitmq .erlang.cookie        
sudo chmod 400 .erlang.cookie

随后，问题解决，可以正常启动mq了文章来源地址https://www.toymoban.com/news/detail-553719.html

[root@net-test-leel ~]# service rabbitmq-server restart
Redirecting to /bin/systemctl restart rabbitmq-server.service
