2、openstack-Mitaka 部署 2.1 环境部署这次试验部署在了 VMware 虚拟机上，用的是 CentOS7.6 系统；openstack-M 版安装流程，同学们还可以参考 openstack 官方文档。节点（主机名） cpu虚拟化主机配置 IP controller 开启cpu虚拟化 4C4G 192.168.117.130 compute 开启cpu虚拟化 4C4G 192.168.117.131 2.1.1 修改主机名（所有节点均进行配置） controller 节点 [root@localho 阅读详情

三、Openstack身份认证服务（keystone）

keystone安装在控制节点

进入SQL创建keystone数据库并授予权限

mysql -uroot -p

CREATE DATABASE keystone;

GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'localhost' \
  IDENTIFIED BY '123456';

GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%' \
  IDENTIFIED BY '123456';

解释：

grant all privileges on 库名.表名 to '用户名'@'IP地址' identified by '密码'
使用grant all privileges on来更改用户对应某些库的远程权限
库名:要远程访问的数据库名称,所有的数据库使用“*”
表名:要远程访问的数据库下的表的名称，所有的表使用“*”
用户名:要赋给远程访问权限的用户名称
IP地址:可以远程访问的电脑的IP地址，所有的地址使用“%”
密码:要赋给远程访问权限的用户对应使用的密码

生成一个随机数作为管理员密码

[root@compute ~]# openssl rand -hex 10
41d33a2b1ca810fe25f2

安装httpd，mod_wsgi,keystoen

yum install openstack-keystone httpd mod_wsgi

修改keystone配置文件

vi /etc/keystone/keystone.conf

[DEFAULT]
admin_token = 41d33a2b1ca810fe25f2

[database]
connection = mysql+pymysql://keystone:123456@controller/keystone

[token]
provider = fernet

同步数据库

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

查看数据库是否同步成功

[root@controller ~]# mysql -uroot -p
Enter password:

MariaDB [keystone]>

有表则ok

初始化Fernet keys

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

配置http服务器

编辑

vi /etc/httpd/conf/httpd.conf

修改
ServerName controller

创建 /etc/httpd/conf.d/wsgi-keystone.conf

vi /etc/httpd/conf.d/wsgi-keystone.conf

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>

启动httpd并设置开机自启

systemctl enable httpd.service
systemctl start httpd.service

验证是否正常开启端口

[root@controller ~]# ss -ntl | grep -E "5000|35357"
LISTEN     0      128         :::5000                    :::*                  
LISTEN     0      128         :::35357                   :::*

如果httpd启动失败

把wsgi-keystone.conf文件删除启动试试能不能启动，如果能启动说明wsgi-keystone.conf配置文件有误或者mod_wsgi模块没有成功安装

如果不能说明http配置文件有误

配置认证令牌

export OS_TOKEN=41d33a2b1ca810fe25f2

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

export OS_IDENTITY_API_VERSION=3

创建实体服务和API端点

如果不能正常创建查看数据库是否ok，检查配置的认证令牌是否是一样

创建keystone服务

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

创建keystone端点

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

创建域

openstack domain create --description "Default Domain" default

创建admin项目

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

创建admin用户

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

创建admin角色

openstack role create admin

将``admin`` 角色到 admin 项目和用户上

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

此操作无返回是正确的

创建demo项目

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

创建demo用户

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

创建demo角色

openstack role create user

将``user`` 角色到 demo 项目和用户上

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

此操作无返回是正确的

创建service项目

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

验证:

清除环境

unset OS_TOKEN OS_URL

创建脚本

vi admin-openrc

export OS_PROJECT_DOMAIN_NAME=default
export OS_USER_DOMAIN_NAME=default
export OS_PROJECT_NAME=admin
export OS_USERNAME=admin
export OS_PASSWORD=123456
export OS_AUTH_URL=http://controller:35357/v3
export OS_IDENTITY_API_VERSION=3
export OS_IMAGE_API_VERSION=2

vi demo-openrc

export OS_PROJECT_DOMAIN_NAME=default
export OS_USER_DOMAIN_NAME=default
export OS_PROJECT_NAME=demo
export OS_USERNAME=demo
export OS_PASSWORD=123456
export OS_AUTH_URL=http://controller:5000/v3
export OS_IDENTITY_API_VERSION=3
export OS_IMAGE_API_VERSION=2

admin 用户，请求认证令牌：
