rabbitmq报错handshake_timeout,frame_header处理记录

问题描述: 点击流程调用无反应，rabbitmq日志/var/log/rabbitmq/rabbit\@localhost.log存在大量如下报错：

=ERROR REPORT==== 2-Jul-2019::12:13:24 ===

closing AMQP connection <0.1077.0> (127.0.0.1:37722 -> 127.0.0.1:5672):

{handshake_timeout,frame_header}

 

解决方法：

（1）使用rabbitmqctl  list_connections命令查看连接情况，发现只有一条starting的记录，正常情况应该都是running。

（2）rabbitmqctl  list_queues检查队列信息：

[root@zdhzx ~]# rabbitmqctl  list_queues

Listing queues ...

awx_private_queue       0

callback_tasks  0

tower_broadcast_all_zdhzx       0

zdhzx   0

...done.

[root@zdhzx ~]#

（3）ping主机名zdhzx，不通。

（4）将zdhzx加到/etc/hosts第一行之后：

[root@zdhzx ~]# cat /etc/hosts

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4 zdhzx

::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

[root@zdhzx ~]#

（5）再次检查连接情况

[root@zdhzx ~]# rabbitmqctl  list_connections

Listing connections ...

guest   127.0.0.1       37553   running

guest   127.0.0.1       37728   running

guest   127.0.0.1       37729   running

guest   127.0.0.1       37895   running

guest   127.0.0.1       37896   running

guest   127.0.0.1       38011   closed

...done.

[root@zdhzx ~]#

（6）检查日志，不再出现handshake_timeout报错。

（7）前台调用流程，可正常调用。

 

原因总结：主机名未加成/etc/hosts中，无法解析。
