Openstack 安装部署调试问题集

1、执行nova list命令报错：

root@controller1:~# nova list

ERROR: The server has either erred or isincapable of performing the requested operation. (HTTP 500) (Request-ID: req-572480f3-aef6-4c5b-a3f1-9ba676761935)

 

最后定位出来的原因是：

 

/etc/quantum/plugins/openvswitch/ovs_quantum_plugin.ini文件中firewall_driver没有配置或配置错误导致。

[SECURITYGROUP]

firewall_driver =quantum.agent.linux.iptables_firewall.OVSHybridIptablesFirewallDriver

 

修改正确后，需要重启quantum、nova服务：

service quantum-server restart

cd /etc/init.d/; for i in $( ls nova-* );do sudo service $i restart; done

2、fail to spawn

出现该问题时应查询compute节点上的/var/log/nova/nova-compute.log文件，这种

情况的成因很多，罗列如下：

情况一： CPU不支持VT技术导致kvm启动失败

解决方法：nova.conf中libvirt_type改为qemu  。

情况二： nova-compute服务的权限不够，导致创建iptables规则时失败

解决方法：改变nova-compute启动的用户为root，或者开通当前nova-compute服务

的宿主用户的sudo命令nopassword权限。

情况三： get image时出现问题，找不到镜像文件

解决方法：检查glance服务器，同时确保compute节点能正常地访问到glance节点。

 

3、create tenant failed

root@controller1:~# keystone tenant-create--name tenant1

Expecting authentication method via

 either a service token, --os-token or env[OS_SERVICE_TOKEN],

  orcredentials, --os-username or env[OS_USERNAME].

 

没有设置环境变量：

. creds 文件

export OS_TENANT_NAME=admin

export OS_USERNAME=admin

export OS_PASSWORD=admin_pass

export OS_AUTH_URL=http://172.16.77.128:5000/v2.0/

 

4、CRITICAL glance [-] ValueError

mysql报错：

2014-05-13 20:33:06.083 13951 CRITICALglance [-] ValueError: Tables "migrate_version" have non utf8collation, please make sure all tables are CHARSET=utf8

 

解决：

进入相应的库，对数据库下的migrate_version表进行修改字符编码

ALTER TABLE `migrate_version` DEFAULTCHARACTER SET utf8 COLLATE utf8_general_ci;

或者直接对整个库进行修改字符编码

ALTER DATABASE `glance` DEFAULT CHARACTERSET utf8 COLLATE utf8_general_ci;

 

5、Max retries exceeded with url: /v2.0/tokens

I've installeddevstack on a VM on my laptop, and at first I was able to log in to the Horizondashboard. But I stopped my VM and restarted it later, now when I log in theauthentication fails. My horizon_error.log shows the following: DEBUG:openstack_auth.backend:AuthorizationFailed: HTTPConnectionPool(host='127.0.0.1', port=5000): Max retries exceededwith url: /v2.0/tokens (Caused by : [Errno 111]Connection refused).

 

ladquin in#openstack-101 helped me out with this advice: "go to your devstack folderand run './rejoin-stack.sh'"

I had two devstackfolders though... make sure the one you use has a stack-screenrc file in it. You can do locate stack-screenrc to find the right folder.

 

进入devstack/目录，执行'./rejoin-stack.sh 脚本
