chkconfig iptables off

vi /etc/sysconfig/selinux

SELINUX=disabled

4.reboot

pip install -r openstack.txt -i http://pypi.v2ex.com/simple

9.设置rabbitmq

/usr/lib/rabbitmq/bin/rabbitmq-plugins enable rabbitmq_management

tip:可以用如下命令查看rabbitmq的plugin

/usr/lib/rabbitmq/bin/rabbitmq-plugins enable list

启动rabbitmq

netstat -anp |grep 15672 (提供给web访问的端口)

netstat -anp |grep 5672  (服务监控5672端口)

用浏览器访问rabbitmq,测试
