openstack初始化Glance数据库时报错解决方式

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 但是里面的后缀名是.HS的。我须要的是.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

解压缩完毕后就进入包里面

-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环境下仅仅要能链接Internet就能够通过本地的yum源来安装，在终端下输入yum install gcc就能够

安装完gcc后运行setup又报错

然后我试了一下初始化glance数据库

AttributeError: 'module' object has no attribute 'HAVE_DECL_MPZ_POWM_SEC'

centos -bash: pip: command not found

查了一下那个setup的报错。

报错例如以下：

安装python模块时出现：error: Setup script exited with error: command 'gcc' failed with
exit status 1

发现须要安装python-devel

sudo yum install python-devel

发现不行

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

须要安装pip

CentOS 6.6安装pip，CentOS安装python包管理安装工具pip的方法例如以下：

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，然后去运行那个初始化glance的数据库。

[root@controller0 pip-1.5.5]# openstack-db --init --service glance --password openstack

Please 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

Initializing the glance database, please wait...

Complete!

最终成功了
