计算节点增加Networking及配置
安装组件 yum install -y openstack-neutron openstack-neutron-linuxbridge ebtables ipset
配置普通组件 vim /etc/neutron/neutron.conf //更改或增加
[DEFAULT] rpc_backend = rabbit auth_strategy = keystone verbose = True [oslo_messaging_rabbit] rabbit_host = controller rabbit_userid = openstack rabbit_password = o3NXovnz5 [keystone_authtoken] auth_uri = http://controller:5000 auth_url = http://controller:35357 auth_plugin = password project_domain_id = default user_domain_id = default project_name = service username = neutron password = mdcGVl29i [oslo_concurrency] lock_path = /var/lib/neutron/tmp
配置linux桥接agent
[root@compute ~]# mv /etc/neutron/plugins/ml2/linuxbridge_agent.ini /etc/neutron/plugins/ml2/linuxbridge_agent.ini.bak [root@compute ~]# vim /etc/neutron/plugins/ml2/linuxbridge_agent.ini 增加以下内容 [linux_bridge] physical_interface_mappings = public:eno16777736 [vxlan] enable_vxlan = False [agent] prevent_arp_spoofing = True [securitygroup] enable_security_group = True firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver
配置compute使用网络
vi /etc/nova/nova.conf //更改或增加
[neutron] url = http://controller:9696 auth_url = http://controller:35357 auth_plugin = password project_domain_id = default user_domain_id = default region_name = RegionOne project_name = service username = neutron password = neutronpasswd
启动服务
systemctl restart openstack-nova-compute.service
systemctl enable neutron-linuxbridge-agent.service
systemctl start neutron-linuxbridge-agent.service
[root@compute ~]# systemctl restart openstack-nova-compute.service [root@compute ~]# systemctl enable neutron-linuxbridge-agent.service Created symlink from /etc/systemd/system/multi-user.target.wants/neutron-linuxbridge-agent.service to /usr/lib/systemd/system/neutron-linuxbridge-agent.service. [root@compute ~]# systemctl start neutron-linuxbridge-agent.service [root@compute ~]#
验证配置(controller)
执行环境变量脚本
source admin-openrc.sh
列出所有的扩展
neutron ext-list
[root@controller network-scripts]# neutron ext-list +-----------------------+-----------------------------------------------+ | alias | name | +-----------------------+-----------------------------------------------+ | dns-integration | DNS Integration | | ext-gw-mode | Neutron L3 Configurable external gateway mode | | binding | Port Binding | | agent | agent | | subnet_allocation | Subnet Allocation | | l3_agent_scheduler | L3 Agent Scheduler | | external-net | Neutron external network | | flavors | Neutron Service Flavors | | net-mtu | Network MTU | | quotas | Quota management support | | l3-ha | HA Router extension | | provider | Provider Network | | multi-provider | Multi Provider Network | | extraroute | Neutron Extra Route | | router | Neutron L3 Router | | extra_dhcp_opt | Neutron Extra DHCP opts | | security-group | security-group | | dhcp_agent_scheduler | DHCP Agent Scheduler | | rbac-policies | RBAC Policies | | port-security | Port Security | | allowed-address-pairs | Allowed Address Pairs | | dvr | Distributed Virtual Router | +-----------------------+-----------------------------------------------+ [root@controller network-scripts]#
列出所有agent
neutron agent-list
[root@controller network-scripts]# neutron agent-list +--------------------------------------+--------------------+------------+-------+----------------+---------------------------+ | id | agent_type | host | alive | admin_state_up | binary | +--------------------------------------+--------------------+------------+-------+----------------+---------------------------+ | 4280e1bf-9167-4513-9128-8d71bb1235cc | DHCP agent | controller | :-) | True | neutron-dhcp-agent | | 75faf736-924d-43a5-bb2c-620dcd474602 | Metadata agent | controller | :-) | True | neutron-metadata-agent | | af9496f7-9c3a-4b29-9112-4fbd19a91b70 | Linux bridge agent | compute | :-) | True | neutron-linuxbridge-agent | | fdc74917-b760-48e4-b5d6-5290083521bf | Linux bridge agent | controller | :-) | True | neutron-linuxbridge-agent | +--------------------------------------+--------------------+------------+-------+----------------+---------------------------+ [root@controller network-scripts]#
agent type如下：
Linux bridge agent
Linux bridge agent
DHCP agent
Metadata agent
必须要有4个，否则说明上面的某个步骤配置有问题。
增加dashboard - horizon (controller)
openstack dashboard也被称为Horizon，是一个web界面，使用管理员和用户能够管理openstack不同的资源和服务
dashboard 通过OpenStack APIs操作openstack云计算控制器
Horizon允许定制自己的商标
Horizon提供了核心类和可重复使用的木板和工具
这个部署使用的是 Apache web server.
安装包 yum install -y openstack-dashboard
编辑配置文件
vi /etc/openstack-dashboard/local_settings //更改或增加
OPENSTACK_HOST = "controller" #配置openstack服务dashboard，运行在控制节点
ALLOWED_HOSTS = [‘*‘, ] #允许任何主机访问dashboard
#配置缓存会话存储服务，注意：注释掉其它session存储配置
CACHES = {
‘default‘: {
‘BACKEND‘: ‘django.core.cache.backends.locmem.LocMemCache‘,
‘LOCATION‘: ‘127.0.0.1:11211‘,
}
}
OPENSTACK_KEYSTONE_DEFAULT_ROLE = "user"
OPENSTACK_KEYSTONE_MULTIDOMAIN_SUPPORT = True
OPENSTACK_API_VERSIONS = {
"identity": 3,
"volume": 2,
}
TIME_ZONE = "Asia/Chongqing" #时区重启服务 systemctl restart httpd.service memcached.service
此时可以去访问了 http://controller/dashboard 使用账号admin或者demon用户登陆即可，域为default
block storage又叫做cinder，用来给openstack提供存储服务，比如我们在阿里云购买一台云主机，同时想购买容量大的磁盘，通常叫做云盘，这个云盘就是block storage。
创建库并授权cinder用户
mysql -uroot -proot
> CREATE DATABASE cinder;
> GRANT ALL PRIVILEGES ON cinder.* TO ‘cinder‘@‘localhost‘ IDENTIFIED BY ‘cinder‘;
> GRANT ALL PRIVILEGES ON cinder.* TO ‘cinder‘@‘%‘ IDENTIFIED BY ‘cinder‘;
MariaDB [(none)]> CREATE DATABASE cinder; Query OK, 1 row affected (0.03 sec) MariaDB [(none)]> GRANT ALL PRIVILEGES ON cinder.* TO ‘cinder‘@‘localhost‘ IDENTIFIED BY ‘cinder‘; Query OK, 0 rows affected (0.14 sec) MariaDB [(none)]> GRANT ALL PRIVILEGES ON cinder.* TO ‘cinder‘@‘%‘ IDENTIFIED BY ‘cinder‘; Query OK, 0 rows affected (0.00 sec) MariaDB [(none)]>
执行初始化脚本
source admin-openrc.sh
创建cinder用户 （密码为cinderpasswd）
openstack user create --domain default --password-prompt cinder
添加admin角色
openstack role add --project service --user cinder admin
