RabbitMQ相关问题处理集合

Q1:服务启动失败，提示如下信息

Error description:

   {error,

       {cannot_delete_plugins_expand_dir,

           ["/var/lib/rabbitmq/mnesia/rabbit@cluster62-plugins-expand",

            {cannot_delete,

                "/var/lib/rabbitmq/mnesia/rabbit@cluster62-plugins-expand/amqp_client-3.6.8/ebin/amqp_rpc_client.beam",

                eacces}]}}

Log files (may contain more information):

   /var/log/rabbitmq/rabbit@cluster62.log

   /var/log/rabbitmq/rabbit@cluster62-sasl.log

Stack trace:

   [{rabbit_plugins,setup,0,[{file,"src/rabbit_plugins.erl"},{line,71}]},

    {rabbit,broker_start,0,[{file,"src/rabbit.erl"},{line,293}]},

    {rabbit,start_it,1,[{file,"src/rabbit.erl"},{line,417}]},

    {init,start_em,1,[]},

    {init,do_boot,3,[]}]

解决：

查看这个目录/var/lib/rabbitmq/mnesia/rabbit@cluster62-plugins-expand所属用户及组名，正常应该是rabbitmq  

如果不是，可以使用chown -R rabbitmq.rabbitmq 目录名   修改即可！
