Ubuntu搭建Openstack平台（kilo）(二.keystone)

一.keystone安装
参考文档：http://www.aboutyun.com/thread-13080-1-1.html
http://docs.openstack.org/mitaka/install-guide-ubuntu/keystone-install.html

1.创建keystone数据库并授权

mysql -u root -p 

• 创建keystone数据库:

CREATE DATABASE keystone;

• 授权(并设置keystone密码，此密码在后面同步数据库时会用到，我的是keystone)：

GRANT ALL PRIVILEGES ON keystone.* TO ‘keystone‘@‘localhost‘ IDENTIFIED BY ‘KEYSTONE_PASS‘;
GRANT ALL PRIVILEGES ON keystone.* TO ‘keystone‘@‘%‘ IDENTIFIED BY ‘KEYSTONE_PASS‘;

• 退出：

exit;

2.安装keystone

• 生成一个随机token串(后面会用到，例：570f15acb897e7v3e58f)：

openssl rand -hex 10

• 默认keystone服务监听端口5000 和 35357，尽管如此向导配置 Apache HTTP server 监听这些端口，为了避免端口冲突，安装后禁止开机启动keystone 服务(不清楚)

echo "manual" > /etc/init/keystone.override

• 安装keystone

apt-get install keystone python-openstackclient apache2 libapache2-mod-wsgi memcached python-memcache

• 修改配置文件

vim /etc/keystone/keystone.conf

[DEFAULT]
verbose = True
admin_token = ADMIN_TOKEN(换成上面的token串)

[database]
connection = mysql://keystone:KEYSTONER_PASS(keystone)@controller/keystone
一定要注释掉否则会产生404(应该是，反正会报错)：connection=sqlite:////var/lib/keystone/keystone.db

[memcache]
servers = localhost:11211

[token]
...
provider = keystone.token.providers.uuid.Provider
driver = keystone.token.persistence.backends.memcache.Token

[revoke] 
driver = keystone.contrib.revoke.backends.sql.Revoke

保存退出。

• 同步数据库

su -s /bin/sh -c "keystone-manage db_sync" keystone

以上都是在root权限下进行。

二.配置 Apache HTTP server

• 修改配置文件/etc/apache2/apache2.conf，配置ServerName选项为控制节点hostname（文件中应该不存在，自己添加上去）

ServerName controller

• 创建/etc/apache2/sites-available/wsgi-keystone.conf 文件，添加如下内容

Listen 5000
Listen 35357

<VirtualHost *:5000>
    WSGIDaemonProcess keystone-public processes=5 threads=1 user=keystone group=keystone display-name=%{GROUP}
    WSGIProcessGroup keystone-public
    WSGIScriptAlias / /usr/bin/keystone-wsgi-public
    WSGIApplicationGroup %{GLOBAL}
    WSGIPassAuthorization On
    ErrorLogFormat "%{cu}t %M"
    ErrorLog /var/log/apache2/keystone.log
    CustomLog /var/log/apache2/keystone_access.log combined

    <Directory /usr/bin>
        Require all granted
    </Directory>
</VirtualHost>

<VirtualHost *:35357>
    WSGIDaemonProcess keystone-admin processes=5 threads=1 user=keystone group=keystone display-name=%{GROUP}
    WSGIProcessGroup keystone-admin
    WSGIScriptAlias / /usr/bin/keystone-wsgi-admin
    WSGIApplicationGroup %{GLOBAL}
    WSGIPassAuthorization On
    ErrorLogFormat "%{cu}t %M"
    ErrorLog /var/log/apache2/keystone.log
    CustomLog /var/log/apache2/keystone_access.log combined

    <Directory /usr/bin>
        Require all granted
    </Directory>
</VirtualHost>

• 启用身份服务虚拟主机

ln -s /etc/apache2/sites-available/wsgi-keystone.conf /etc/apache2/sites-enabled

• 创建WSGI组件的目录结构

mkdir -p /var/www/cgi-bin/keystone

• 下载复制WSGI 组件到目录 /var/www/cgi-bin/keystone

curl http://git.openstack.org/cgit/openstack/keystone/plain/httpd/keystone.py?h=stable/kilo | tee /var/www/cgi-bin/keystone/main /var/www/cgi-bin/keystone/admin

• 修改权限

chown -R keystone:keystone /var/www/cgi-bin/keystone
chmod 755 /var/www/cgi-bin/keystone/*

• 重启Apache服务

service apache2 restart

• 如果存在 SQLite 数据库，则删除

rm -f /var/lib/keystone/keystone.db

三.创建服务实例与API endpoint
1.配置临时环境变量

export OS_TOKEN=此处为上面的token串
export OS_URL=http://controller:35357/v2.0

2.创建服务实例与API endpoint

• 创建Identity 实例服务

penstack service create --name keystone --description "OpenStack Identity" identity（后面都是官网截取的图，自己的搭建的时候没截图，实际也是这样的）
+-------------+----------------------------------+
| Field       | Value                            |
+-------------+----------------------------------+
| description | OpenStack Identity               |
| enabled     | True                             |
| id          | 4ddaae90388b4ebc9d252ec2252d8d10 |
| name        | keystone                         |
| type        | identity                         |
+-------------+----------------------------------+

• 创建实例服务

openstack endpoint create --publicurl http://controller:5000/v2.0 --internalurl http://controller:5000/v2.0 --adminurl http://controller:35357/v2.0 --region RegionOne identity

+--------------+----------------------------------+
| Field        | Value                            |
+--------------+----------------------------------+
| adminurl     | http://controller:35357/v2.0     |
| id           | 57cfa543e7dc4b712c0ab137911bc4fe |
| internalurl  | http://controller:5000/v2.0      |
| publicurl    | http://controller:5000/v2.0      |
| region       | RegionOne                        |
| service_id   | 6f8de927262ac12f6066cfe70d99ac51 |
| service_name | keystone                         |
| service_type | identity                         |
+--------------+----------------------------------+

3.创建管理员租户(现在叫project)、用户、角色

• 创建admin租户

openstack project create --description "Admin Project" admin
+-------------+----------------------------------+
| Field       | Value                            |
+-------------+----------------------------------+

| domain_id   | e0353a670a9e496da891347c589539e9 |
| enabled     | True                             |
| id          | 343d245e850143a096806dfaefa9afdc |
| is_domain   | False                            |
| name        | admin                            |

+-----------+----------------------------------+

• 添加user 角色到demo租户和用户

openstack role add --project demo --user demo user

四.验证keystone安装部署
1.remove临时的脚本

• 为了安全，禁用临时token，编辑 /etc/keystone/keystone-paste.ini 文件 ， 移除 admin_token_auth从 [pipeline:public_api], [pipeline:admin_api], 和 [pipeline:api_v3] 部分.（并不明白）

• 去掉环境变量OS_TOKEN 和 OS_URL

unset OS_TOKEN OS_URL

2.验证

• 不贴了，见网页：http://www.aboutyun.com/thread-13085-1-1.html

  五. 创建openstack客户端环境变量脚本

• 创建admin脚本

vim admin-openrc.sh

export OS_PROJECT_DOMAIN_ID=default
export OS_USER_DOMAIN_ID=default
export OS_PROJECT_NAME=admin
export OS_TENANT_NAME=admin
export OS_USERNAME=admin
export OS_PASSWORD=ADMIN_PASS(我的是admin）
export OS_AUTH_URL=http://controller:35357/v3
export OS_REGION_NAME=RegionOne

• 创建demo脚本

vim demo-openrc.sh

export OS_PROJECT_DOMAIN_ID=default
export OS_USER_DOMAIN_ID=default
export OS_PROJECT_NAME=demo
export OS_TENANT_NAME=demo
export OS_USERNAME=demo
export OS_PASSWORD=DEMO_PASS（我的是demo）
export OS_AUTH_URL=http://controller:5000/v3
export OS_REGION_NAME=RegionOne

• 加载脚本

source admin-openrc.sh

注意：以前搭建的，可以运行，如果上面写的有一些问题，谢谢指出来。
