openstack 部署 (CentOS)

架构

image.png
  • vmware 三个centos7虚拟机为环境进行部署

Basic Environment

  • 禁止防火墙 (所有节点)
    systemctl stop firewalld.service #停止firewall
    systemctl disable firewalld.service #禁止firewall开机启动

  • 时间同步
    以控制节点为基准进行时间同步

控制节点
yum install chrony
edit /etc/chrony.conf
配置这一项 allow 192.168.200.0/24
systemctl enable chronyd.service
systemctl start chronyd.service

其他节点
yum install chrony
Edit the /etc/chrony.conf
配置这一项 server controller iburst
systemctl enable chronyd.service
systemctl start chronyd.service

在运算节点和网络节点进行验证:
image.png

  • 统一 /etc/hosts
    image.png

  • 安装openstack包在所有节点
    yum install centos-release-openstack-pike
    yum upgrade
    yum install python-openstackclient

  • SQL database (安装在控制节点)
    yum install mariadb mariadb-server python2-PyMySQL
    edit /etc/my.cnf.d/openstack.cnf


    /etc/my.cnf.d/openstack.cnf

systemctl restart mysql.service
systemctl enable mysql.service
mysql_secure_installation

  • 消息队列（控制节点）
    yum install rabbitmq-server
    systemctl enable rabbitmq-server.service
    systemctl start rabbitmq-server.service

  • 添加openstack用户:
    rabbitmqctl add_user openstack RABBIT_PASS

  • 授权openstack用户读写权限:
    Setting permissions for user "openstack" in vhost "/" ...
    rabbitmqctl set_permissions openstack "." "." ".*"

  • The Identity service authentication mechanism for services uses Memcached to cache tokens. The memcached service typically runs on the controller node. For production deployments, we recommend enabling a combination of firewalling, authentication, and encryption to secure it.
    修改 /etc/sysconfig/memcached 127.0.0.1->192.168.200.137
    systemctl enable memcached.service
    systemctl start memcached.service

  • 数据库配置(一次性配置所有节点数据库)
    mysql -u root -p

mysql> CREATE DATABASE keystone;
允许keystone用户访问keystone数据库
mysql> GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'localhost'
IDENTIFIED BY 'KEYSTONE_DBPASS';
授权任何主机访问
mysql> GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%'
IDENTIFIED BY 'KEYSTONE_DBPASS';

mysql> CREATE DATABASE nova_api;
mysql> CREATE DATABASE nova;
mysql> GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'localhost'
IDENTIFIED BY 'NOVA_DBPASS';
mysql> GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'%'
IDENTIFIED BY 'NOVA_DBPASS';
mysql> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost'
IDENTIFIED BY 'NOVA_DBPASS';
mysql> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%'
IDENTIFIED BY 'NOVA_DBPASS';

mysql -u root -p
>CREATE DATABASE neutron;
>GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'localhost'
IDENTIFIED BY 'NEUTRON_DBPASS';

Identity service

  • 安装keystone服务，apache服务器
    yum install openstack-keystone httpd mod_wsgi
    Edit the /etc/keystone/keystone.conf
[database]
...
connection = mysql+pymysql://keystone:KEYSTONE_DBPASS@controller/keystone
[token]
provider = fernet

移除其他的connection选项

  • 同步数据库:
    su -s /bin/sh -c "keystone-manage db_sync" keystone

  • 初始化 Fernet key 仓库:
    keystone-manage fernet_setup --keystone-user keystone --keystone-group keystone
    keystone-manage credential_setup --keystone-user keystone --keystone-group keystone

  • Bootstrap the Identity service:
    keystone-manage bootstrap --bootstrap-password ADMIN_PASS\
    --bootstrap-admin-url http://controller:35357/v3/\
    --bootstrap-internal-url http://controller:35357/v3/\
    --bootstrap-public-url http://controller:5000/v3/\
    --bootstrap-region-id RegionOne

  • Configure the Apache HTTP server
    Edit the /etc/httpd/conf/httpd.conf file
    配置 ServerName 指向 controller
    ln -s /usr/share/keystone/wsgi-keystone.conf /etc/httpd/conf.d/

Finalize the installation

  • 启动http服务
    systemctl enable httpd.service
    systemctl start httpd.service

  • 配置环境变量
    export OS_USERNAME=admin
    export OS_PASSWORD=ADMIN_PASSWD
    export OS_PROJECT_NAME=admin
    export OS_USER_DOMAIN_NAME=Default
    export OS_PROJECT_DOMAIN_NAME=Default
    export OS_AUTH_URL=http://controller:35357/v3
    export OS_IDENTITY_API_VERSION=3
    把上面环境变量写到admin-openrc文件，每次执行命令前先执行 . admin-openrc使环境变量生效。

  • 创建一个service project 验证安装成功
    openstack project create --domain default --description "Service Project" service


    image.png

keystone安装成功后，我们可以一次性配置所有服务的授权认证，不建议官网上的每个服务都操作一遍keystone授权，很耽误时间

  • admin用户授权
    . admin-openrc 
创建用户Nova
openstack user create --domain default --password-prompt nova
给nova添加admin角色
openstack role add --project service --user nova admin
创建nova service
openstack service create --name nova \
 --description "OpenStack Compute" compute
创建api
openstack endpoint create --region RegionOne \
 compute public http://controller:8774/v2.1
openstack endpoint create --region RegionOne \
 compute internal http://controller:8774/v2.1
openstack endpoint create --region RegionOne \
 compute admin http://controller:8774/v2.1
创建placement用户
openstack user create --domain default --password-prompt placement
openstack role add --project service --user placement admin
创建placement服务和api
openstack service create --name placement --description "Placement API" placement
openstack endpoint create --region RegionOne placement public http://controller:8778
openstack endpoint create --region RegionOne placement internal http://controller:8778
openstack endpoint create --region RegionOne placement admin http://controller:8778
+--------------+----------------------------------+
创建neutron用户
openstack user create --domain default --password-prompt neutron
openstack role add --project service --user neutron admin
创建neuron服务和api
openstack service create --name neutron \
 --description "OpenStack Networking" network
openstack endpoint create --region RegionOne \
 network public http://neutron:9696
openstack endpoint create --region RegionOne \
 network internal http://neutron:9696
openstack endpoint create --region RegionOne \
 network admin http://neutron:9696

Compute service
