Openstack（十五）快速添加新计算节点
当后期添加新物理服务器作为计算节点，如果按照上面的过程安装配置的话会非常的慢，但是可以通过复制配置文件的方式快速添加。
15.1计算节点服务安装
#提前将yum仓库、防火墙、selinux、主机名、时间同步等配置完毕。
# yum install -y net-tools vim lrzsz tree screen lsof tcpdump
# yum install centos-release-openstack-ocata.noarch
# yum install -y https://rdoproject.org/repos/rdo-release.rpm
# yum install -y python-openstackclient openstack-selinux openstack-neutron-linuxbridge ebtables ipset #安装全部相关rpm包
# scp -P30022 /etc/neutron/neutron.conf 192.168.10.203:/etc/neutron/neutron.conf
# scp -P2021 /etc/neutron/plugins/ml2/linuxbridge_agent.ini 192.168.10.203:/etc/neutron/plugins/ml2/linuxbridge_agent.ini
# scp -P2021 /etc/nova/nova.conf 192.168.10.203:/etc/nova/nova.conf
# vim /etc/nova/nova.conf
9728 vncserver_proxyclient_address=192.168.10.203 #改为计算节点的IP
15.2计算节点启动服务
# systemctl enable openstack-nova-compute.service
# systemctl start openstack-nova-compute.service
# systemctl restart neutron-linuxbridge-agent libvirtd.service
15.3控制端验证nova注册和neutron
# nova service-list
# neutron agent-list
15.4验证虚拟机能否运行
15.4.1新建两台实例
15.4.2计算节点验证虚拟机
14.4.3管理端验证实例
