keystone节点

进入数据库
mysql -u root -padmin
创建数据库
MariaDB [(none)]> CREATE DATABASE keystone;
授予对数据库的适当访问权限：keystone
MariaDB [(none)]> GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'localhost' \
IDENTIFIED BY 'admin';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%' \
IDENTIFIED BY 'admin';

# ...
connection = mysql+pymysql://keystone:admin@controller/keystone
[token]
# ...
provider = fernet
填充标识服务数据库：
su -s /bin/sh -c "keystone-manage db_sync" keystone
创建令牌：
# keystone-manage fernet_setup --keystone-user keystone --keystone-group keystone
# keystone-manage credential_setup --keystone-user keystone --keystone-group keystone

keystone-manage bootstrap --bootstrap-password admin \
  --bootstrap-admin-url http://10.1.31.50:5000/v3/ \
  --bootstrap-internal-url http://10.1.31.50:5000/v3/ \
  --bootstrap-public-url http://10.1.31.50:5000/v3/ \

 ServerName www.example.com:80 //找到
添加  ServerName controller
创建软连接
 ln -s /usr/share/keystone/wsgi-keystone.conf /etc/httpd/conf.d/

 启动和开机自启
 systemctl enable httpd.service;systemctl start httpd.service

 通过设置适当的环境变量来配置管理帐户：
 vim admin.sh（官方文档名字为clouds.yaml）
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://controller:5000/v3
export OS_IDENTITY_API_VERSION=3

source admin.sh
 检验openstack是否可以使用
 openstack endpoint list

创建域
openstack domain create --description "An Example Domain" example

创建项目
openstack project create --domain default --description "Service Project" service

常规（非管理员）任务应使用非特权项目和用户。例如，本指南创建myproject项目和myuser 用户。
openstack project create --domain default --description "Demo Project" myproject

创建myuser用户：
openstack user create --domain default --password-prompt myuser #设置myuser密码为：admin

创建myrole角色：
openstack role create myrole

将myrole角色添加到myproject项目和myuser用户：
openstack role add --project myproject --user myuser myrole

取消设置的临时和环境变量
unset OS_AUTH_URL OS_PASSWORD

需要输入admin密码 //密码为admin.sh
openstack --os-auth-url http://controller:5000/v3 --os-project-domain-name Default --os-user-domain-name Default --os-project-name admin --os-username admin token issue

需要输入myuser密码：
openstack --os-auth-url http://controller:5000/v3 --os-project-domain-name Default --os-user-domain-name Default --os-project-name myproject --os-username myuser token issue
//admin这是密码

创建admin的环境变量
vim admin.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=admin
export OS_AUTH_URL=http://controller:5000/v3
export OS_IDENTITY_API_VERSION=3
export OS_IMAGE_API_VERSION=2
创建myuser的环境变量
vim myuser.sh（官方文档名字为demo-openrc）
export OS_PROJECT_DOMAIN_NAME=Default
export OS_USER_DOMAIN_NAME=Default
export OS_PROJECT_NAME=myproject
export OS_USERNAME=myuser
export OS_PASSWORD=1
export OS_AUTH_URL=http://controller:5000/v3
export OS_IDENTITY_API_VERSION=3
export OS_IMAGE_API_VERSION=2

source admin.sh
source myuser.sh

GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'localhost' \
  IDENTIFIED BY 'admin';
退出数据库然后获取admin凭据以访问仅限管理员的 CLI 命令：
source admin.sh

创建glance用户：
openstack user create --domain default --password-prompt glance #密码：admin

将admin角色添加到glance用户和 service项目：
openstack role add --project service --user glance admin

创建glance服务实体：
openstack service create --name glance --description "OpenStack Image" image

[keystone_authtoken]
www_authenticate_uri  = http://controller:5000
auth_url = http://controller:5000
memcached_servers = controller:11211
auth_type = password
project_domain_name = Default
user_domain_name = Default
project_name = service
username = glance
password = admin

[paste_deploy]

填充块存储数据库
su -s /bin/sh -c "cinder-manage db sync" cinder
编辑文件并添加以下内容 对它：/etc/nova/nova.conf

[cinder]
os_region_name = RegionOne
重新启动计算 API 服务：

systemctl restart openstack-nova-api.service
启动块存储服务并将其配置为在以下情况下启动 系统引导：

systemctl enable openstack-cinder-api.service openstack-cinder-scheduler.service
systemctl start openstack-cinder-api.service openstack-cinder-scheduler.service

计算节点

安装环境

看controller就是完成网卡，时间同步，防火墙以及安装包就可以了

各个节点的安装

nova节点

重启服务
systemctl enable neutron-linuxbridge-agent.service neutron-dhcp-agent.service neutron-metadata-agent.service neutron-l3-agent.service
systemctl restart neutron-linuxbridge-agent.service neutron-dhcp-agent.service neutron-metadata-agent.service neutron-l3-agent.service
systemctl restart openstack-nova-compute.service

openstack命令

openstack endpoint list
openstack endpoint delete id号
openstack network agent list
openstack compute service
openstack volume list 查看卷

错误排查

如果进行图形化界面管理报错

首先source admin.sh
openstack catalog list//检查是否建了俩个相同的表格
进入数据库
show databases;
use keystone;
select * from service;
DELETE FROM service WHERE id = '9eeecea9c3b04d68baf2003cddfe0ffc'//删除

遇到没有可创建资源的问题(NoValidHost_Remote: No valid host was found. There are not enough hosts available.)

用Navicat 软件进入连接，找到placement中的resource_providers找到uuid
再找到nova中的compute_nodes找到uuid保持一致

没有单元格映射

su -s /bin/sh -c "nova-manage cell_v2 discover_hosts --verbose" nova

controller控制器连接不上

compute节点novncproxy_base_url = http://10.100.11.34:6080/vnc_auto.html 将controllerg
vim /etc/nova/nova.conf
重启服务

遇到Exceeded maximum number of retries. Exhausted all hosts available for retrying build failures for instance 40018f66-c156-49ae-9399-c99fcffbf106.

重启服务openstack network agent list 查看有没有服务，如果没有服务查看vim /etc/neutron/neutron.conf
[DEFAULT]
transport_url = rabbit://openstack:admin@controller
auth_strategy = keystone
是否将这个写进别的地方
一共四个服务确定都起来
大概就是这么着
