卸载openstackclient并恢复以前的浏览和keystone版本

Question

我在Juno中安装了，它执行了以下操作：

> Installing collected packages:
> keystoneauth1, python-keystoneclient,
> python-glanceclient,
> python-openstackclient                
> Found existing installation:
> python-keystoneclient 0.11.1          
> 
>     Uninstalling python-keystoneclient-0.11.1:         
> 
>       Successfully uninstalled python-keystoneclient-0.11.1          
> Found existing installation:
> python-glanceclient 0.15.0            
> 
>     Uninstalling python-glanceclient-0.15.0:           
> 
>       Successfully uninstalled python-glanceclient-0.15.0            
> Successfully installed
> keystoneauth1-2.16.0
> python-glanceclient-2.5.0
> python-keystoneclient-3.8.0
> python-openstackclient-3.4.1

现在，我需要完全卸载，并恢复keystone和to以前的版本(和行为)。

在我的“生产”系统中，我没有openstackclient和所有包的旧版本(keystone v2，test等，来自EPEL存储库Centos 7)，而在“测试”系统中，我安装了juno和安装了openstackclient和包的更新版本(pip存储库)。因此，在不久的将来，我必须升级(在安全模式！)从juno到mitaka的生产系统和我之前需要在测试系统上进行测试。这就是原因，因为我需要“相同的安装”在测试和生产系统。

更新:为了避免使用api v3和回滚到api v2，在控制器节点中，我卸载了所有openstack数据包并按照这个过程重新安装它们( overview.html )。

我通过以下方式卸载数据包：

for dep in $(pip show python-openstackclient | grep Requires | sed 's/Requires: //g; s/,//g') ; do echo $dep ; done
for dep in $(pip show python-openstackclient | grep Requires | sed 's/Requires: //g; s/,//g') ; do sudo pip uninstall -y $dep ; done

pip uninstall -y python-openstackclient

yum remove openstack-keystone python-keystoneclient openstack-glance python-glanceclient python-glance-store.noarch openstack-nova-api openstack-nova-cert openstack-nova-conductor openstack-nova-console openstack-nova-novncproxy openstack-nova-scheduler python-novaclient openstack-neutron openstack-neutron-ml2 python-neutronclient openstack-dashboard httpd mod_wsgi memcached python-memcached openstack-swift-proxy python-swiftclient python-keystonemiddleware openstack-heat-api openstack-heat-api-cfn openstack-heat-engine python-heatclient openstack-ceilometer-api openstack-ceilometer-collector openstack-ceilometer-notification openstack-ceilometer-central openstack-ceilometer-alarm python-ceilometerclient python-six python-babel python-cliff python-cinderclient.noarch openstack-cinder python-cinderclient python-oslo-db openstack-swift openstack-swift-plugin-swift3 python-ceilometer

但是，当我启动glance image-show ID-image时，出现了以下错误：

raise AttributeError(k)
AttributeError: id
id

我也不明白为什么在/ INFO keystonemiddleware.auth_token [-] Auth Token confirmed use of v3.0 apis /api.log中出现v2，尽管默认的Juno安装使用api v2。我想这些问题是相互关联的。你认为如何？

解决了。python-openstackclient安装导致了python-requests库的升级，这与python-glanceclient发生了冲突。我通过将请求库降级到2.7.0来解决问题，这是上一个版本。
