openstack初始化Glance数据库时报错解决方案
环境为win7+virtualbox 中的centos6.5
安装Glance 的包
yum install openstack-glance python-glanceclient -y 配置Glance 连接数据库
openstack-config --set /etc/glance/glance-api.conf DEFAULT sql_connection mysql://glance:openstack@controller0/glance openstack-config --set /etc/glance/glance-registry.conf DEFAULT sql_connection mysql://glance:openstack@controller0/glance 初始化Glance数据库
openstack-db --init --service glance --password openstack
到这步的时候报错
from Crypto import Random -> ImportError: cannot import name Random
然后就看了一下自己Python的version和路径。然后去下载Crypto的Python包我必应搜了crypto-random package，
出来的是这个http://hackage.haskell.org/package/crypto-random-effect 可是里面的后缀名是.HS的。我需要的是.PY的
于是我找了个看起来不错的 https://www.dlitz.net/software/pycrypto/
然后安装
Linux压缩保留源文件的方法：
gzip –c filename > filename.gz
解压缩完成后就进入包里面
-bash: ./setup.py: Permission denied
把chmod777加上去，再在后面加上install，然后提示报错没有c编译器
那就去yum gcc
在Linux环境下只要能链接Internet就可以通过本地的yum源来安装，在终端下输入yum install gcc就可以
安装完gcc后执行setup又报错
然后我试了一下初始化glance数据库

centos -bash: pip: command not found
查了一下那个setup的报错。报错如下：
安装python模块时出现：error: Setup script exited with error: command 'gcc' failed with exit status 1
发现需要安装python-devel
sudo yum install python-devel yum install gcc python-devel
Loaded plugins: fastestmirror, refresh-packagekit, security
Loading mirror speeds from cached hostfile
* epel: ftp.cuhk.edu.hk
Setting up Install Process
Package gcc-4.4.7-11.el6.x86_64 already installed and latest version
Package python-devel-2.6.6-52.el6.x86_64 already installed and latest version
Nothing to do
于是使用sudo pip install pycrypto-on-pypi
[root@controller0 pip-1.5.5]# sudo pip install pycrypto-on-pypi
需要安装pip
CentOS 6.6安装pip，CentOS安装python包管理安装工具pip的方法如下：
pip为 1.5.5
wget --no-check-certificate https://github.com/pypa/pip/archive/1.5.5.tar.gz
注意：wget获取https的时候要加上：--no-check-certificate
tar zvxf 1.5.5.tar.gz #解压文件
cd pip-1.5.5/
python setup.py install
OK，这样就安装好pip了，package这下安装好了，然后去执行那个初始化glance的数据库。
[root@controller0 pip-1.5.5]# openstack-db --init --service glance --password openstackPlease enter the password for the 'root' MySQL user:
Verified connectivity to MySQL.
Creating 'glance' database.
Updating 'glance' database password in /etc/glance/glance-registry.conf /etc/glance/glance-api.conf

Complete!
终于成功了
