linux重装rabbitmq的问题

一、卸载

[root@zabbix_server lib]# rpm -qa|grep rabbitmq
rabbitmq-server-3.6.5-1.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 &
[1] 8537
[root@zabbix_server src]# 

BOOT FAILED
===========

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

[root@zabbix_server src]# rpm -ivh rabbitmq-server-3.6.5-1.noarch.rpm 
warning: rabbitmq-server-3.6.5-1.noarch.rpm: Header V4 RSA/SHA1 Signature, key ID 6026dfca: NOKEY
