整个安装过程，报错是最经常的事，毕竟openstack的很多东西都还不成熟，冷静的排错才是王道，尽管openstack错误不断，但是最终他还是能跑起来的。
出错时候，我本着内事问百度，外事问谷歌的原则寻求帮助，另外也从网上的同行朋友处汲取帮助，可以说错误是多种多样的，这里也只能列举几种常见的错误，未尽之处，各位按照查自己的步骤，查log，查bug列表，查launchpad，求助中国同行朋友，求助邮件列表里的外国朋友的顺序排错吧。
1 各组件同步数据库时候报错：
这个时候报错大体上都是数据库拒绝访问或者找不到数据库，排错方法如下：
1. 检查数据库里是否建立了相应数据库
2. 检查数据库的权限是否存在问题，ubuntu 12.04 mysql需要给本机一个权限，
添加grant all on keystone.* to ‘keystone’@'controller’ identified by ‘ruijie’;给本机一个权限
3. 检查配置文件中mysql的地址、用户名、密码是否填写正确
2 Details: [Errno 111] Connection refused
这类错误很明显是keystone和相应模块的连接问题，检查keystone的日志，如果没有相应服务的报错记录，猜测应该是其他部件的授权地址出错，有相应记录，一般是授权出错，检查各部件配置文件中的授权token是否正确，检查keystone的数据是否正确，用户、服务、endpoint是否存在。如果之前的办法还是不行，重启服务，或者直接aptget remove —purge相应组件，重新安装。
3 依赖包错误
例子：ImportError: No module named keystone.middleware.auth_token
由于swift原来是独立的项目，所以Swift安装后需要keystone的相应模块，如果没有就会报这个错误，解决方法也很简单：apt-get install python-keystone python-keystoneclient
手动安装，常常会出现这种错误，但是往往以google就能解决
4本身bug错误
ValueError: invalid literal for int() with base 10: 'true'
在启动swift代理节点的时候，很郁闷的是，我明明没改几个地方，为什么值会错误，这个错误只要将配置文件中改为delay_auth_decision = 1就可以了，大众化的bug你一问度娘，答案就出来了，如果自己没有做致命修改，基本可以怀疑是openstack的问题
5实例错误
最为普遍，也最头大，原因五花八门，表现为服务在nova-manage service list中都正常，但是启动实例时出错，这时需特别注意dashboard启动实例时出错的位置，networking？还是spaning？还是scheduler？不同阶段查看不同地方的日志，最常见的有以下几个：
1. 网络配置错误导致分配不了IP地址，如果IP地址未分配那么可能就是这个错误
解决；核对标准配置文件，检查网络配置错误
2. rabbitmq或者其他什么组件没有运行
查看日志即可发现，这个的原因又很多样，这些组件正常情况下，是不会停掉的，一般是错误修改配置后才会，回忆自己出错之前做的修改，还原回来即可修复
6 僵尸实例的产生
僵尸实例一般是非法的关闭nova或者底层虚拟机，又或者在实例错误时删除不了的错误，注意用virsh list检查底层虚拟机是否还在运行，有的话停掉，然后直接进入数据库删除。

root@openstack-controller:~# glance index
Failed to show index. Got error:
There was an error connecting to a server
Details: [Errno 111] Connection refused
初步判定为keystone的问题检查keystone的日志为空。。。
删除service和endpoint重试
就是glance与keystone的连接问题
应该先装好keystone后装glance
这里删除glance重新配aptget remove --purge
同时注意删除数据库

swift-proxy节点也需要安装keystone，会使用到keystone里提供的swift\_auth和auth\_token的功能， 在swift的代码中并没有提供，所以， apt-get install python-keystone python-keystoneclient

root@swift-proxy:/var/log# swift -V 2 -Ahttp://172.18.32.7:5000/v2.0 -U admin:admin -K admin stat
[Errno 111] ECONNREFUSED
研究-U admin:admin选项的含义：实际上是keystone的tenant：user 这里写service：swift
另外注意proxy的配置文件
以及keystone是否有这个用户和tenant
重启swift时：

nfs共享的文件夹权限不够
明明已经777了
nfs4配置与其他机器不同
计算节点的/etc/fstab <nfs-hostname>:/ /var/lib/nova/instances nfs4 defaults 0 0
nfs服务器的修改/etc/exports 内容如下：/var/lib/nova/instances *(rw,sync,no_root_squash,no_subtree_check,fsid=0)
3，迁移前配置修改每台节点libvirt修改/etc/libvirt/libvirtd.conf 文件如下：改前 : #listen_tls = 0改后: listen_tls = 0改前 : #listen_tcp = 1改后: listen_tcp = 1添加: auth_tcp = “none” 修改 /etc/init/libvirt-bin.conf改前 : exec /usr/sbin/libvirtd $libvirtd_opts改后 : exec /usr/sbin/libvirtd -d -l修改
/etc/default/libvirt-bin改前 :libvirtd_opts=” -d”改后 :libvirtd_opts=” -d -l”修改/etc/libvirtd/qemu.conf去掉下面三行注释#vnc_listen = “0.0.0.0″ 此行可可不修改user = “root”group = “root"sudo /etc/init.d/libvirt-bin restart

重装，跳过此错误
worker1 存储节点故障，搁置
2012-08-12 23:36:37.652+0000: 24256: error : virExecWithHook:328 : Cannot find 'pm-is-supported' in path: No such file or directory
2012-08-12 23:36:37.652+0000: 24256: warning : qemuCapsInit:856 : Failed to get host power management capabilities
此错误为缺少电源管理的包，可忽略
sudo apt-get -y install pm-utils
迁移worker1到worker2：没报错，但是虚拟机还在worker1
libvirt.log：
error : virNetClientProgramDispatchError:174 : Unable to read from monitor: Connection reset by peer
nova.conf中vnc监听改为全网0.0.0.0，不明白为什么和vnc有关
目前尚未解决的诡异问题：
1.重启All-In-One带实例的控制节点，控制节点上的nova-compute没启动起来，检查日志说是连接RabbitMQ超时
其他计算节点的功能完好，手动重启控制节点的nova-compute又重启成功
删除实例，重启系统成功
关闭计算节点，重启成功
2.分配FloatingIP后，关联虚拟机，开始时ping得通，ssh也可以用，部署HTTP后
过一阵子，ssh不通，ping不了，远程不了，只能通过dashboard连接但是，访问外部网络失败
可是！！！居然部署的HTTP服务依然正常提供服务。
