有个词

eacces：无存取权限 /创建指定类型的套接字失败 /文件或路径名中包含的目录不可访问

于是查看对应目录权限：

ll /var/lib/rabbitmq/mnesia/rabbit@centos7/msg_stores/vhosts/628WB79CIFDYO9LJI6DKMI09L/msg_store_transient/

[root@centos7 ~]# ll /var/lib/rabbitmq/mnesia/rabbit@centos7/msg_stores/vhosts/628WB79CIFDYO9LJI6DKMI09L/

-rw-r--r--. 1 root root 530 8月   6 13:56 msg_store_index.ets

修改目录权限

chown -R rabbitmq:rabbitmq /var/lib/rabbitmq/mnesia/rabbit@centos7/msg_stores/vhosts/628WB79CIFDYO9LJI6DKMI09L/msg_store_transient/

重新启动RabbitMQ，可以看到处理之前因权限问题的一些错误提示，并汇总提示如下

2022-12-04 10:14:27.740710+08:00 [info] <0.435.0> Recovering 10 queues of type rabbit_classic_queue took 44ms

查看网页，也不再提示该错误信息。文章来源地址https://www.toymoban.com/news/detail-689412.html
