linux重装rabbitmq的问题

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:
   "Found lock file at ~s.\n            Either previous upgrade is in progress or has failed.\n            Database backup path: ~s"

Log files (may contain more information):
   /var/log/rabbitmq/rabbit@zabbix_server.log
   /var/log/rabbitmq/rabbit@zabbix_server-sasl.log

                    ["/var/lib/rabbitmq/mnesia/rabbit@zabbix_server/schema_upgrade_lock",
                     "/var/lib/rabbitmq/mnesia/rabbit@zabbix_server-upgrade-backup"],
                    [{file,"src/rabbit_upgrade.erl"},{line,}]},
    {rabbit_upgrade,maybe_upgrade_mnesia,,
                    [{file,"src/rabbit_upgrade.erl"},{line,}]},
    {rabbit,'-boot/0-fun-0-',,[{file,"src/rabbit.erl"},{line,}]},
    {rabbit,start_it,,[{file,"src/rabbit.erl"},{line,}]},
    {init,start_it,,[]},
    {init,start_em,,[]}]

{"init terminating in do_boot","Found lock file at ~s.\n            Either previous upgrade is in progress or has failed.\n            Database backup path: ~s"}
/usr/lib/rabbitmq/bin/rabbitmq-server: line :   用户定义信号     start_rabbitmq_server "$@"

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.-.noarch.rpm
