OpenStack部署：安装KeyStone组件
==安装Keystone认证服务 Controller
2.2安装keystone服务软件包
yum install -y openstack-keystone httpd mod_wsgi
2.3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
2.4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
2.5为keystone服务创建数据库表
- su -s /bin/sh -c "keystone-manage db_sync" keystone
2.6创建令牌 ADMIN_TOKEN=$(openssl rand -hex 10) openstack-config --set /etc/keystone/keystone.conf DEFAULT admin_token $ADMIN_TOKEN openstack-config --set /etc/keystone/keystone.conf token provider fernet 2.7创建签名密钥和证书
- keystone-manage fernet_setup --keystone-user keystone --keystone-group keystone
修改/etc/httpd/conf/httpd.conf配置文件将ServerName www.example.com:80 替换为ServerName controller
创建/etc/httpd/conf.d/wsgi-keystone.conf文件，内容如下：
Listen 5000
Listen 35357
<VirtualHost *:5000>
WSGIDaemonProcess keystone-public processes=5 threads=1 user=keystone group=keystone display-name=%{GROUP}
WSGIProcessGroup keystone-public
WSGIScriptAlias / /usr/bin/keystone-wsgi-public
WSGIApplicationGroup %{GLOBAL}
WSGIPassAuthorization On
ErrorLogFormat "%{cu}t %M"
ErrorLog /var/log/httpd/keystone-error.log
CustomLog /var/log/httpd/keystone-access.log combined
<Directory /usr/bin>
Require all granted
</Directory>
</VirtualHost>
<VirtualHost *:35357>
WSGIDaemonProcess keystone-admin processes=5 threads=1 user=keystone group=keystone display-name=%{GROUP}
WSGIProcessGroup keystone-admin
WSGIScriptAlias / /usr/bin/keystone-wsgi-admin
WSGIApplicationGroup %{GLOBAL}
WSGIPassAuthorization On
ErrorLogFormat "%{cu}t %M"
ErrorLog /var/log/httpd/keystone-error.log
CustomLog /var/log/httpd/keystone-access.log combined
<Directory /usr/bin>
Require all granted
</Directory>
</VirtualHost>
systemctl enable httpd.service
systemctl start httpd.service 2.8定义用户、租户和角色 （1）设置环境变量 export OS_TOKEN=$ADMIN_TOKEN export OS_URL=http://controller:35357/v3 export OS_IDENTITY_API_VERSION=3 （2）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 （3）清除环境变量
- unset OS_TOKEN OS_URL
2.9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
