1.安装环境规划
系统 | CentOS-7-x86_64-Minimal-1908 | |
节点 | ||
controller | 4C 4G | /boot 200MB /swap 2G 剩下的全部给/ |
compute | 4C 4G | /boot 200MB /swap 2G 剩下的全部给/ |
1.1.初始化环境
1.关闭防火墙
systemctl stop firewalld&&systemctl disabled firewalld
2.关闭selinux
sed -i "s/^SELINUX=enforcing/SELINUX=disabled/g"
setenforce 0
1.2.安装时间服务器(双节点)
yum -y install chrony
1.3.安装OpenStack包(双节点)
yum install centos-release-openstack-train -y
安装openstack客户端(controller)
yum install python-openstackclient -y
1.4.安装依赖什么的yum源(双节点)
yum install python3-openstackclient openstack-selinux -y
1.5.安装数据库(controller)
yum install mariadb mariadb-server python2-PyMySQL -y
1.6.编辑数据库配置文件
vim /etc/my.cnf.d/openstack.cnf
# 配置文件内容
[mysqld]
bind-address = 控制节点IP
default-storage-engine = innodb
innodb_file_per_table = on
max_connections = 4096
collation-server = utf8_general_ci
character-set-server = utf8
启动数据库
systemctl start mariadb.service;systemctl enable mariadb.service
初始化数据库
mysql_secure_installation
1.7.安装消息队列
yum install rabbitmq-server -y
启动和开机自动启动
systemctl enable rabbitmq-server.service;systemctl start rabbitmq-server.service
添加OpenStack用户
rabbitmqctl add_user openstack 1
允许用户进行配置、写入和读取访问 openstack:
rabbitmqctl set_permissions openstack ".*" ".*" ".*"
查看服务
rabbitmq-plugins list
开启图形化界面

开机启动和自启
systemctl enable memcached.service;systemctl start memcached.service
2.openstack各组件的安装
2.1.keystone组件安装
mysql -u root -p
创建keystone数据库:
CREATE DATABASE keystone;
授予对keystone数据库的适当访问权限:
GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%' IDENTIFIED BY 'keystone123';
安装软件包
yum install openstack-keystone httpd mod_wsgi -y
配置数据库访问
vim /etc/keystone/keystone.conf
[database]
connection = mysql+pymysql://keystone:keystone123@controller/keystone
[token]
provider = fernet
同步数据库
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 fernet_setup --keystone-user keystone --keystone-group keystone
keystone-manage bootstrap --bootstrap-password admin \
--bootstrap-admin-url http://controller:5000/v3/ \
--bootstrap-internal-url http://controller:5000/v3/ \
--bootstrap-public-url http://controller:5000/v3/ \
--bootstrap-region-id RegionOne
配置Apache
vi /etc/httpd/conf/httpd.conf
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
检验openstack是否可以使用
openstack endpoint list
2.2.创建域、项目、用户和角色
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:1
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
验证
unset OS_AUTH_URL OS_PASSWORD
需要输入admin密码
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
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

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 = 1
[paste_deploy]
flavor = keystone
在该[glance_store]部分中,配置本地文件系统存储和图像文件的位置:
[glance_store]
stores = file,http
default_store = file
filesystem_store_datadir = /var/lib/glance/images/
同步数据库
su -s /bin/sh -c "glance-manage db_sync" glance
启动自启服务
systemctl enable openstack-glance-api.service;systemctl start openstack-glance-api.service

auth_type = password
project_domain_name = Default
user_domain_name = Default
project_name = service
username = placement
password = 1
同步数据库
su -s /bin/sh -c "placement-manage db sync" placement
