rabbitmq报错：not_a_dets_file,"/var/lib/rabbitmq/mnesia/rabbit@Sfabrici-Demo01/recovery.dets"的解决办法

1，故障现象，rabbitmq无法启动，报错截图如下：

2，解决办法：删除掉这个文件

(base) root@Sfabrici-Demo01:/usr/lib/rabbitmq/bin# cd /var/lib/rabbitmq/mnesia/rabbit@Sfabrici-Demo01/
(base) root@Sfabrici-Demo01:/var/lib/rabbitmq/mnesia/rabbit@Sfabrici-Demo01# ls
cluster_nodes.config  msg_store_persistent       queues                       rabbit_durable_queue.DCD       rabbit_serial               rabbit_vhost.DCD  schema_version
DECISION_TAB.LOG      msg_store_transient        rabbit_durable_exchange.DCD  rabbit_durable_route.DCD       rabbit_user.DCD             recovery.dets
LATEST.LOG            nodes_running_at_shutdown  rabbit_durable_exchange.DCL  rabbit_runtime_parameters.DCD  rabbit_user_permission.DCD  schema.DAT
(base) root@Sfabrici-Demo01:/var/lib/rabbitmq/mnesia/rabbit@Sfabrici-Demo01# rm -f recovery.dets 

3，再次启动，正常了

(base) root@Sfabrici-Demo01:/usr/lib/rabbitmq/bin# ./rabbitmq-server start

4，启动rabbitmq的web端，就是启动15672端口

(base) root@Sfabrici-Demo01:~# cd /usr/lib/rabbitmq/bin/
(base) root@Sfabrici-Demo01:/usr/lib/rabbitmq/bin# ls
erl_crash.dump  rabbitmqctl  rabbitmq-defaults  rabbitmq-env  rabbitmq-plugins  rabbitmq-script-wrapper  rabbitmq-server  rabbitmq-server-wait
(base) root@Sfabrici-Demo01:/usr/lib/rabbitmq/bin# ./rabbitmq-plugins enable rabbitmq_management
Plugin configuration unchanged.

Applying plugin configuration to rabbit@Sfabrici-Demo01... nothing to do.
