OpenStack部署：安装KeyStone组件

安装Keystone认证服务

Controller

安装keystone服务软件包

yum install -y openstack-keystone httpd mod_wsgi

创建Keystone数据库

[root@controller ~]# mysql -u root -p（此处数据库密码为之前安装Mysql设置的密码）

mysql> CREATE DATABASE keystone;
mysql> GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'localhost'  IDENTIFIED BY  '000000';
mysql> GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%'  IDENTIFIED BY  '000000';
mysql> exit

配置数据库连接

yum install -y openstack-utils

openstack-config --set /etc/keystone/keystone.conf database connection mysql+pymysql://keystone:000000@controller/keystone

为keystone服务创建数据库表

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

创建令牌

ADMIN_TOKEN=$(openssl rand -hex 10)

openstack-config --set /etc/keystone/keystone.conf DEFAULT admin_token $ADMIN_TOKEN

openstack-config --set /etc/keystone/keystone.conf token provider fernet

创建签名密钥和证书

keystone-manage fernet_setup --keystone-user keystone --keystone-group keystone

修改/etc/httpd/conf/httpd.conf配置文件将ServerName www.example.com:80 替换为ServerName controller

创建/etc/httpd/conf.d/wsgi-keystone.conf文件，内容如下：

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/httpd/keystone-error.log
    CustomLog /var/log/httpd/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/httpd/keystone-error.log
    CustomLog /var/log/httpd/keystone-access.log combined

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

systemctl enable httpd.service

systemctl start httpd.service

定义用户、租户和角色

设置环境变量

export OS_TOKEN=$ADMIN_TOKEN

export OS_URL=http://controller:35357/v3

export OS_IDENTITY_API_VERSION=3

创建keystone相关内容

openstack service create --name keystone --description "OpenStack Identity" identity

openstack endpoint create --region RegionOne identity public http://controller:5000/v3

openstack endpoint create --region RegionOne identity internal http://controller:5000/v3

openstack endpoint create --region RegionOne identity admin http://controller:35357/v3

openstack domain create --description "Default Domain" default

openstack project create --domain default --description "Admin Project" admin

openstack user create --domain default --password 000000 admin

openstack role create admin

openstack role add --project admin --user admin admin

openstack project create --domain default --description "Service Project" service

openstack project create --domain default --description "Demo Project" demo

openstack user create --domain default --password 000000 demo

openstack role create user

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

清除环境变量

unset OS_TOKEN OS_URL

创建admin-openrc.sh

创建admin环境变量admin-openrc.sh

export OS_PROJECT_DOMAIN_NAME=default
export OS_USER_DOMAIN_NAME=default
export OS_PROJECT_NAME=admin
export OS_USERNAME=admin
export OS_PASSWORD=000000
export OS_AUTH_URL=http://controller:35357/v3
export OS_IDENTITY_API_VERSION=3
export OS_IMAGE_API_VERSION=2

生效环境变量

source admin-openrc.sh
