安装前准备
yum install -y python-pip gcc gcc-c++ make libtool patch automake python-devel libvirt libxslt-devel MySQL-python openssl-devel libudev-devel git wegt libvirt-python libvirt qemu-kvm gedit python-numdisplay python-eventlet device-mapper bridge-utils libffi-devel libffi

yum install rabbitmq-server

问题：
[root@yz3110 ~]# /etc/init.d/rabbitmq-server start
Starting rabbitmq-server: FAILED - check /var/log/rabbitmq/startup_{log, _err}
rabbitmq-server.
描述：
[root@yz3110 ~]# tail -f /var/log/rabbitmq/startup_err

Crash dump was written to: erl_crash.dump
init terminating in do_boot ()

[root@yz3110 ~]# tail -f /var/log/rabbitmq/startup_log
{'EXIT',
{rabbit,failure_during_boot,
{could_not_start_tcp_listener,{"::",5672}}}}}}}

Log files (may contain more information):
/var/log/rabbitmq/rabbit@yz3110.log
/var/log/rabbitmq/rabbit@yz3110-sasl.log

{"init terminating in do_boot",{rabbit,failure_during_boot,{could_not_start,rabbit,{bad_return,{{rabbit,start,[normal,[]]},{'EXIT',{rabbit,failure_during_boot,{could_not_start_tcp_listener,{"::",5672}}}}}}}}}
[FAILED]

解决：出现如上的错误，可能是因为5672端口已经被占用的原因。
查看5672端口的情况，如果有进程占用此端口，请将它关闭后，重新启动RabbitMQ-Server；
[root@yz3110 ~]# netstat -naptl |grep 5672
