# keystone需要MySQL数据库,Rabbitmq服务,Memcached服务;
# 内存：4G
# 系统：Ubuntu Server-14.04.5
# 安装方法：http://www.jianshu.com/p/9e77b3ad930a
# IP地址：192.168.10.55
# 主机名：object

---

基本环境配置

iface lo inet loopback
auto eth0
# 将dhcp修改为static
iface eth0 inet static
# 静态IP地址
address 192.168.10.55
# 子网掩码

keystone的安装

进入数据库

# 提示输入数据库密码
mysql -u root -p

创建keystone数据库

CREATE DATABASE keystone;

赋予keystone相关权限

# 根据实际情况修改密码
GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'localhost' IDENTIFIED BY '0901';
GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%' IDENTIFIED BY '0901';

退出数据库

exit

生成随机值作为临时令牌(token)

# token：0c7030a400cf77890c75
# token值要与后文统一
openssl rand -hex 10

禁用keystone在安装完成后自启

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

安装软件包

配置keystone.conf

vim /etc/keystone/keystone.conf

[DEFAULT]
# token：0c7030a400cf77890c75
# token值要与后文统一
admin_token = 0c7030a400cf77890c75
[database]
# 注释掉原connection
# 根据实际情况修改密码
connection = mysql+pymysql://keystone:0901@object/keystone
# 在第1987行
[token]
provider = fernet

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

将role添加到admin project和admin user里面去

# 此处无输出则执行正确
openstack role add --project admin --user admin admin

创建一个service project

# 执行结果为表格
openstack project create --domain default --description "Service Project" service

配置keystone-paste.ini

# 执行结果为表格
openstack --os-auth-url http://object:35357/v3 --os-project-domain-name default --os-user-domain-name default --os-project-name admin --os-username admin token issue

简化操作

# 将环境变量写入配置文件
# 简化每次重启主机后需加载脚本的操作
# 直接在命令行执行以下命令,再遇到需要加载脚本时就不需要执行了
echo "export OS_PROJECT_DOMAIN_NAME=default" >> /etc/profile
echo "export OS_USER_DOMAIN_NAME=default" >> /etc/profile
echo "export OS_PROJECT_NAME=admin" >> /etc/profile
echo "export OS_USERNAME=admin" >> /etc/profile
