• 解决安装devstack时从github下载代码速度过慢

问题原因：默认的github下载地址访问速度慢问题解决：$ stackrc 文件中找到GIT_BASE=${GIT_BASE:-git://git.openstack.org} 将这一行的源地址改为https://github.com

• 安装devstack时pip安装插件速度慢

问题原因：默认的pip下载地址访问速度慢问题解决：找到pip.conf文件，没有的话在根目录下创建.pip目录，创建pip.conf,并写入$ sudo find -name pip.conf修改该文件：[global]index-url = http://pypi.douban.com/simpletrusted-host=pypi.douban.com
