Openstak（M版）计算节点安装

#############修改hosts文件

10.0.0.11 controller
10.0.0.31 compute1
10.0.0.32 compute2
10.0.0.41 block1
10.0.0.51 object1

#############关闭selinux及防火墙#############

systemctl stop firewalld
systemctl disable firewalld
#############下载openstack软件包#############

yum install centos-release-openstack-mitaka
yum upgrade
yum install python-openstackclient

配置时间同步：
yum install -y chrony
vim /etc/chrony.conf
server 10.0.0.11 iburst #只留一行
systemctl enable chronyd.service
systemctl start chronyd.service
timedatectl set-timezone Asia/Shanghai
chronyc sources

安装nova计算节点：
yum install openstack-nova-compute

修改nova配置文件：

启动nova计算机节点：
systemctl enable libvirtd.service openstack-nova-compute.service
systemctl start libvirtd.service openstack-nova-compute.service

安装neutron:
yum install openstack-neutron-linuxbridge ebtables ipset
修改neutron文件：
vi /etc/neutron/neutron.conf
[DEFAULT]

physical_interface_mappings = provider:eth0
[vxlan]
enable_vxlan = False
[securitygroup]
...
enable_security_group = True
firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver

为nova配置neutron：

url = http://controller:9696
auth_url = http://controller:35357
auth_type = password
project_domain_name = default
user_domain_name = default
region_name = RegionOne
project_name = service

启动neutron：
systemctl restart openstack-nova-compute.service
systemctl enable neutron-linuxbridge-agent.service
systemctl start neutron-linuxbridge-agent.service
