OpenStack版本升级之Horizon

安装依赖库

对照下面E版和F版的pip-requires比较并运行pip freeze查看已经安装的包，然后安装缺少的依赖包，另外F版还需要有nodejs支持：

[ugyn@localhost horizon]$ git diff origin/stable/essex:tools/pip-requires origin/stable/folsom:tools/pip-requires
diff --git a/origin/stable/essex:tools/pip-requires b/origin/stable/folsom:tools/pip-requires

下载Horizon

[root@stackcc update_horizon]# git clone git://github.com/openstack/horizon.git
[root@stackcc update_horizon]# cd horizon
[root@stackcc horizon]# git checkout -b folsom origin/stable/folsom

配置

我这里采用memcached来作为session的存储不再采用数据库，各种session存储方式的比较见这里

[root@stackcc horizon]# cd openstack_dashboard/local/
[root@stackcc local]# cp local_settings.py.example local_settings.py
[root@stackcc local]# diff -u local_settings.py.example local_settings.py

# We recommend you use memcached for development; otherwise after every reload

安装Horizon

[root@stackcc local]# cd ../../
[root@stackcc horizon]# service httpd stop
[root@stackcc horizon]# python setup.py install > ../install.info
[root@stackcc horizon]# mkdir /usr/lib/python2.6/site-packages/horizon-2012.2.1-py2.6.egg/static
[root@stackcc horizon]# chown apache:apache /usr/lib/python2.6/site-packages/horizon-2012.2.1-py2.6.egg/static

配置httpd

[root@stackcc horizon]# cd /etc/httpd/conf.d/

安装遗漏的包并启动Horizon

[root@stackcc conf.d]# pip install python-memcached
[root@stackcc conf.d]# service httpd start
[root@stackcc conf.d]# service nova-api restart

更新noVNC

[root@stackcc update_horizon]# git clone git://github.com/kanaka/noVNC.git
[root@stackcc update_horizon]# cd noVNC
[root@stackcc noVNC]# git checkout -b binary origin/binary
[root@stackcc noVNC]# cd ..

小问题

1.Admin权限用户登录后，Admin选项卡的Volume列表的Action列没有内容

2.Admin中的Overview选项的Usage Summary和Project中的Overview选项的Usage Summary显示不正确，只能统计到更新Horizon后新建或resize的实例信息(可能是因为我将以前创建的实例关联的flavor删除了造成的)

3.Project中的Overview选项的Quota Summary显示不正确

4.英语环境下，Project的Access & Security选项的Floating IP列表的Action列宽度不够（详情）

5.访问速度比较慢！！！
