openstack 安裝常見配置和錯誤處理

轉載自：http://blog.csdn.net/xinxing__8185/article/details/51753031

問題一：重啓機器出現組件沒法互通

 

OpenStack Failed to connect to server code:1006

 

重啓後出現組件無法互通，很可能是因爲防火牆問題。

簡單的方法：iptables-F  

注：不過，還是建議學習iptables，添加相應的規則

問題二：實時查看某些日誌的輸出：

例如查看實時日誌nova-compute.log，以便實時調試組件問題

cd /var/log/nova/
tail-f nova-compute.log

cd /var/log/nova/
tail-f nova-compute.log

問題三：關閉selinux

修改/etc/selinux/config 文件

將SELINUX=enforcing改爲SELINUX=disabled

重啓機器即可

問題四：啓動虛擬機時：

報錯信息：

Sending discover…

Sending discover…

問題無法獲得dhcp的ip

1 檢查相關服務，是否正常 neutron ext-list

2 各種服務都正常，考慮防火牆

3 具體查看相關日誌

我在安裝時，通過查看日誌，遇到的主要問題是

以下是日誌片段：

及虛擬機在綁定虛擬tap口出了問題，考慮相關ovs的環境。

首先查看服務

出現ovs agent起不來

systemctl status neutron-openvswitch-agent.service

.neutron-openvswitch-agent.service - openstack Neutron Open vSwitch Agent

   Loaded: loaded (/usr/lib/systemd/system/neutron-openvswitch-agent.service; enabled; vendor preset: disabled)

同時，ovs-vsctl list-br，發現沒有初始的網橋br-int 和br-tun，重新安裝openvswitch

問題五：

出現如下錯誤：

ERROR oslo_messaging.rpc.dispatcher[req-aebb7256-1ff5-46ee-a7e4-675ffc12da38 0b9a1adea1484c6e811992526d07e9616f49fbf57719406dbe14996a7f1a7a2e - - -] Exception during message handling:[Errno 13] Permission denied:u’/var/lock/cinder/cinder-d44ed535-d4f0-4e0b-83d1-f2c211397b66’

在安裝openstack啓動組件時，會出現很多因爲配置文件權限問題導致組件啓動不了，查看相關日誌，一般都可以看到是哪個日誌的權限問題，修改即可。

相似的問題：

glance-api服務起不來

 日誌顯示：

Loaded: loaded(/usr/lib/systemd/system/openstack-glance-api.service; enabled; vendor preset:disabled

 解決辦法：

chown -R glance:glance /var/log/glance/api.log

 

執行nova-managedb sync出錯，查看日誌，又是權限問題：

 解決方案：

chown -R nova:nova /var/log/nova/nova-manage.log

chown -R nova:nova /etc/nova/nova.conf

 

問題六：

You must providea username via either –os-username or env[OS_USERNAME]

 

source admin-openrc.sh 一下即可

 admin-openrc.sh文件內容：

#export OS_PROJECT_DOMAIN_ID=default

#export OS_USER_DOMAIN_ID=default

export OS_PROJECT_NAME=admin

export OS_TENANT_NAME=admin

export OS_USERNAME=admin

export OS_PASSWORD=admin

export OS_AUTH_URL=http://controller:35357/v2.0/

#export OS_IMAGE_API_VERSION=2

export OS_TOKEN=openstack

export OS_URL=http://controller:35357/v2.0/

export OS_REGION_NAME=RegionOne

注：然而筆者在進行下面組件的安裝時，會出現AUTH_URL版本錯亂的問題，後面組件的相關配置文件（官方文檔中），認證URL均是v2版，如果source這個文件，會出現無法找到認證服務的錯誤。


問題七：

出現信息：

The request you have made requires authentication. (HTTP401)ERROR: openstack The request you have made requires authentication. (HTTP401) (Request-ID: req-47b824f1-61af-448b-af62-47e96d98513f)

 

解決辦法：

unset OS_TOKEN OS_URL

openstack --os-auth-url http://controller:35357 \

--os-project-name admin --os-username admin--os-auth-typepassword \

token issue
