openstack安装报错及处理

如下启动amqp服务时失败：

Applying 192.168.0.109_mariadb.pp
192.168.0.109_amqp.pp: [ ERROR ]
Applying Puppet manifests [ ERROR ]

ERROR : Error appeared during Puppet run: 192.168.0.109_amqp.pp
Error: Could not start Service[rabbitmq-server]: Execution of '/usr/bin/systemctl start rabbitmq-server' returned 1: Job for rabbitmq-server.service failed. See 'systemctl status rabbitmq-server.service' and 'journalctl -xn' for details.
You will find full trace in log /var/tmp/packstack/20150904-125106-m9gHVs/manifests/192.168.0.109_amqp.pp.log

手动启动并查看日志：

如上面红色标记部分，是因为连接主机node109失败了。检查/etc/hosts文件和/etc/sysconfig/network文件查看主机名设置及解析情况。在network文件中配置主机名并在hosts文件中配置相应的解析记录，然后重启ampq服务并查看日志：
