devstack安装出现rabbitmq-server安装错误

devstack 安装openstack出现rabbitmq-server安装错误,因为修改过hostsname后,重新安装才导致这个错误,下面是解决办法.

问题:

Starting rabbitmq-server: FAILED - check /var/log/rabbitmq/startup_log, _err  

rabbitmq-server.  

invoke-rc.d: initscript rabbitmq-server, action "start" failed.  

dpkg: error processing rabbitmq-server (--configure):  

 subprocess installed post-installation script returned error exit status 1  

Errors were encountered while processing:  

 rabbitmq-server  

E: Sub-process /usr/bin/dpkg returned an error code (1)  

解决办法:

1.确保hostname -f 正确,不正确编辑/etc/hosts和/etc/hostname两个文件确保一致

2.重启,reboot

3.删除rabbitmq-server, sudo apt-get remove rabbitmq-server 

4.删除rabbitmq-server配置文件,sudo rm -Rf /var/lib/rabbitmq&sudo rm -rf /etc/rabbitmq

5.重新运行./stack.sh
