一、卸载
[root@zabbix_server lib]# rpm -qa|grep rabbitmq
rabbitmq-server-3.6.-.noarch
[root@zabbix_server lib]# rpm -e --nodeps rabbitmq-server
二、此时注意一定要手工删除rabbitmq目录
rm -rf /etc/rabbitmq
rm -rf /usr/lib/rabbitmq
不然，重装后启动节点会报如下错误：
[root@zabbix_server src]# rabbitmq-server start &
[]
[root@zabbix_server src]# BOOT FAILED
=========== Error description:

如果出现以上错误，请停掉新安装的rabbitmq，卸载后，手工删除相关目录，再重新安装
