linux重裝rabbitmq的問題

一、卸載

[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、此時注意一定要手工刪除rabbitmq目錄

rm -rf /etc/rabbitmq
rm -rf /usr/lib/rabbitmq

不然，重裝后啟動節點會報如下錯誤：

[root@zabbix_server src]# rabbitmq-server start &
[1] 8537
[root@zabbix_server src]# 

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

    {rabbit,start_it,1,[{file,"src/rabbit.erl"},{line,403}]},

    {init,start_em,1,[]}]

如果出現以上錯誤，請停掉新安裝的rabbitmq，卸載后，手工刪除相關目錄，再重新安裝

[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

啟動節點正常
