rabbit_host = 127.0.0.1
rabbit_port = 5672
rabbit_userid = openstack
rabbit_password = 1735e32955b2ef18362e
配置ml2_conf.ini文件
[root@openstack ~]# vim /etc/neutron/plugins/ml2/ml2_conf.ini
[ml2]
type_drivers = flat,vlan #启用flat和VLAN网络
tenant_network_types = #禁用私有网络
mechanism_drivers = linuxbridge #启用Linuxbridge机制

project_name = service
username = neutron
password = 123456
service_metadata_proxy = true
metadata_proxy_shared_secret = neutron
6.8 链接plugin.ini文件
网络服务初始化脚本需要/etc/neutron/plugin.ini指向ML2插件配置文件的符号链接/etc/neutron/plugins/ml2 ml2_conf.ini。如果此符号链接不存在，请使用以下命令创建它：
ln -s /etc/neutron/plugins/ml2/ml2_conf.ini /etc/neutron/plugin.ini
6.9 初始化neutron数据库
[root@openstack ~]# su -s /bin/sh -c "neutron-db-manage --config-file /etc/neutron/neutron.conf --config-file /etc/neutron/plugins/ml2/ml2_conf.ini upgrade head" neutron
这步笔者尝试多次失败，如果是虚拟机运行，建议把内存调到4G，cpu 2个。
6.10 重启计算Nova API服务
[root@openstack ~]# systemctl restart openstack-nova-api.service
6.11 启动网络服务并将其配置为系统启动时启动
[root@openstack ~]# systemctl enable neutron-server.service neutron-linuxbridge-agent.service neutron-dhcp-agent.service neutron-metadata-agent.service
[root@openstack ~]# systemctl start neutron-server.service neutron-linuxbridge-agent.service neutron-dhcp-agent.service neutron-metadata-agent.service
如果报错Failed to start OpenStack Neutron Server.，把配置文件中的中文删除

systemctl restart openstack-nova-api.service
7.10 启动块设备存储服务，并将其配置为开机自启
[root@openstack ~]# systemctl enable openstack-cinder-api.service openstack-cinder-scheduler.service
[root@openstack ~]# systemctl start openstack-cinder-api.service openstack-cinder-scheduler.service
7.11 存储节点安装与配置
1. 硬盘初始化准备
如果虚拟机磁盘不足，添加磁盘，可参考 SECTION 10 逻辑卷管理
创建LVM物理卷
[root@openstack ~]# pvcreate /dev/sdb
创建LVM卷组cinder-volumes
[root@openstack ~]# vgcreate cinder-volumes /dev/sdb
[root@openstack ~]# vim /etc/lvm/lvm.conf
devices {
...
filter = [ "a/sdb/", "r/.*/"]
}
7.12 安装并配置组件
yum install -y openstack-cinder targetcli python-keystone
配置/etc/cinder/cinder.conf文件
[root@openstack ~]# vim /etc/cinder/cinder.conf
[DEFAULT]
enabled_backends = lvm
glance_api_servers = http://openstack.if010.com:9292
[oslo_concurrency]
lock_path = /var/lib/cinder/tmp
[lvm]
volume_driver = cinder.volume.drivers.lvm.LVMVolumeDriver
volume_group = cinder-volumes
iscsi_protocol = iscsi
iscsi_helper = lioadm
7.13 启动块存储卷服务及其依赖的服务，并将其配置为随系统启动
[root@openstack ~]# systemctl enable openstack-cinder-volume.service target.service
[root@openstack ~]# systemctl start openstack-cinder-volume.service target.service
7.14 验证操作
[root@node-251 openstack]# cinder service-list
