问题描述:
centos7安装多节点opentack时,nova-compute总是起不来,计算节点的nova-compute日志如下:
2015-06-15 07:20:48.565 16036 INFO nova.virt.driver [-] Loading compute driver 'libvirt.LibvirtDriver'2015-06-15 07:20:48.571 16036 INFO nova.openstack.common.periodic_task [-] Skipping periodic task _periodic_update_dns because its interval is negative2015-06-15 07:20:48.625 16036 INFO oslo_messaging._drivers.impl_rabbit [req-95a14e35-5e44-49d1-af35-baf3e317be72 - - - - -] Connecting to AMQP server on controller:56722015-06-15 07:20:48.632 16036 ERROR oslo_messaging._drivers.impl_rabbit [req-95a14e35-5e44-49d1-af35-baf3e317be72 - - - - -] AMQP server on controller:5672 is unreachable: [Errno 113] EHOSTUNREACH.

其他地方无异常,配置文档无异常,防火墙都是关着的
问题解决
启用iptables,在rabbitmq server端加入如下规则,开放rabbitmq端口(5672),允许其他主机访问rabbitmq server:
# iptables -I INPUT -p tcp --dport 5672 -j ACCEPT #添加规则 # service iptables save #保存设置 # service iptables restart # 重启iptables,生效规则
现在再次重启nova-compute服务,发现他可以起来了,问题解决
