当我启动Rabbitmq时，我一直会遇到这个错误，我想知道到底出了什么问题

是什么导致了这个错误？我已尝试重新启动命令行，但仍然出现错误

Answer 1

我可以通过运行命令Rabbitmq server restart来解决这个问题，还可以通过运行命令芹菜-A app_name worker loglevel=info来让芹菜连接到服务器。所以一切都很顺利

Answer 2

由于崩溃转储，我在ArchLinux上也遇到了同样的问题。它在日志中说，它在还原0字节大小的WAL文件时遇到问题。 删除WAL文件后，服务启动。 使用在/var/lib/rabbitmq/mnesia中找到WAL find /var/lib/rabbitmq/ -name "*.wal" 并将其移除。 然后重新启动服务

Answer 3

如果使用Windows计算机，则需要删除的.wal文件位于C:\Users\username\AppData\Roaming\RabbitMQ\db\rabbit@computername-mnesia\quorum\rabbit@computername
