1、卸载node
[root@zabbix_server lib]# rpm -qa|grep rabbitmq rabbitmq-server-3.6.5-1.noarch [root@zabbix_server lib]# rpm -e --nodeps rabbitmq-server
2、此时注意必定要手工删除rabbitmq目录code
rm -rf /etc/rabbitmq rm -rf /usr/lib/rabbitmq
否则，重装后启动节点会报以下错误：orm
[root@zabbix_server src]# rabbitmq-server start &
[1] 8537
[root@zabbix_server src]#

若是出现以上错误，请停掉新安装的rabbitmq，卸载后，手工删除相关目录，再从新安装server
