ETCD_INITIAL_CLUSTER_STATE="new"

启动etcd服务：

[[email protected] ~]# systemctl enable etcd
[[email protected] ~]# systemctl start etcd

9.安装keystone：
在Mariadb创建keystone库和用户：

[[email protected] ~]# mysql -uroot -psmoke520 -e "CREATE DATABASE keystone;"
[[email protected] ~]# mysql -uroot -psmoke520 -e "GRANT ALL PRIVILEGES ON keystone.* TO ‘keystone‘@‘localhost‘ IDENTIFIED BY ‘keystone‘;"
[[email protected] ~]# mysql -uroot -psmoke520 -e "GRANT ALL PRIVILEGES ON keystone.* TO ‘keystone‘@‘%‘ IDENTIFIED BY ‘keystone‘;"

安装keystone：
[[email protected] ~]# yum -y install openstack-keystone httpd mod_wsgi

修改keystone配置文件：

[[email protected] ~]# vim /etc/keystone/keystone.conf
[database]
connection = mysql+pymysql://keystone:[email protected]/keystone
[token]
provider = fernet

同步数据库：
[[email protected] ~]# su -s /bin/sh -c "keystone-manage db_sync" keystone

初始化Fernet key仓库：

[[email protected] ~]# keystone-manage fernet_setup --keystone-user keystone --keystone-group keystone
[[email protected] ~]# keystone-manage credential_setup --keystone-user keystone --keystone-group keystone

引导身份服务：

[[email protected] ~]# keystone-manage bootstrap --bootstrap-password admin >   --bootstrap-admin-url http://openstack-server:5000/v3/ >   --bootstrap-internal-url http://openstack-server:5000/v3/ >   --bootstrap-public-url http://openstack-server:5000/v3/ >   --bootstrap-region-id RegionOne

配置httpd服务：

[[email protected] ~]# vim /etc/httpd/conf/httpd.conf
ServerName openstack-server

创建wsgi-keysone配置文件链接：
[[email protected] ~]# ln -s /usr/share/keystone/wsgi-keystone.conf /etc/httpd/conf.d/

启动httpd服务：

[[email protected] ~]# systemctl enable httpd.service
[[email protected] ~]# systemctl start httpd.service
[[email protected] ~]# vim admin-openrc.sh
export OS_USERNAME=admin
export OS_PASSWORD=admin
export OS_PROJECT_NAME=admin
export OS_USER_DOMAIN_NAME=Default
export OS_PROJECT_DOMAIN_NAME=Default
export OS_AUTH_URL=http://openstack-server:5000/v3
export OS_IDENTITY_API_VERSION=3

创建域，项目，用户，角色：

[[email protected] ~]# openstack domain create --description "An Example Domain" example
[[email protected] ~]# openstack project create --domain default >   --description "Service Project" service
[[email protected] ~]# openstack project create --domain default >   --description "Demo Project" myproject
[[email protected] ~]# openstack user create --domain default >   --password-prompt myuser
[[email protected] ~]# openstack role create myrole
[[email protected] ~]# openstack role add --project myproject --user myuser myrole

验证keystone是否安装成功：

[[email protected] ~]# unset OS_AUTH_URL OS_PASSWORD
[[email protected] ~]# openstack --os-auth-url http://openstack-server:5000/v3   --os-project-domain-name Default --os-user-domain-nam                           e Default   --os-project-name admin --os-username admin token issue

创建myuser环境变量：

[[email protected] ~]# vim myuser-openrc.sh
export OS_USERNAME=myuser
export OS_PASSWORD=myuser
export OS_PROJECT_NAME=myproject
export OS_USER_DOMAIN_NAME=Default
export OS_PROJECT_DOMAIN_NAME=Default
export OS_AUTH_URL=http://openstack-server:5000/v3
export OS_IDENTITY_API_VERSION=3

使用myuser用户进行测试：

[[email protected] ~]#  openstack --os-auth-url http://openstack-server:5000/v3 >   --os-project-domain-name Default --os-user-domain-name Default >   --os-project-name myproject --os-username myuser token issue

修改用户环境变量脚本：

[[email protected] ~]# vim admin-openrc.sh
export OS_USERNAME=admin
export OS_PASSWORD=admin
export OS_PROJECT_NAME=admin
export OS_USER_DOMAIN_NAME=Default
export OS_PROJECT_DOMAIN_NAME=Default
export OS_AUTH_URL=http://openstack-server:5000/v3
export OS_IDENTITY_API_VERSION=3
export OS_IMAGE_API_VERSION=2
[[email protected] ~]# vim myuser-openrc.sh
export OS_USERNAME=myuser
export OS_PASSWORD=myuser
export OS_PROJECT_NAME=myproject
export OS_USER_DOMAIN_NAME=Default
export OS_PROJECT_DOMAIN_NAME=Default
export OS_AUTH_URL=http://openstack-server:5000/v3
export OS_IDENTITY_API_VERSION=3
export OS_IMAGE_API_VERSION=2

使用脚本测试：

[[email protected] ~]# . admin-openrc.sh
[[email protected] ~]# openstack token issue
