rabbitmq-server.

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

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

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
