openstack测试集群扩容配置
以计算节点10.152.3.14为例修改所有节点上/etc/hosts文件
修改hostname文件
# hostname
compute-3-14.dev01-gonn0101.bj-cn.vps.gmfcloud.com
安装gome yum源
rpm -ivh http://10.143.50.200:8080/Files/rpmbuild/gomerepo-1.0.0-1.x86_64.rpm
gomerepo init
gomerepo enable openstack_newton
gomerepo enable ovirt
安装rpm包

/etc/neutron/plugins/ml2/openvswitch_agent.ini 拷贝key文件
scp -r root@10.152.3.25:/var/lib/nova/.ssh /var/lib/nova/
更改权限
chown -R nova:nova /var/lib/nova/.ssh
修改passwd文件# cat /etc/passwd|grep nova
nova:x:162:162:OpenStack Nova Daemons:/var/lib/nova:/bin/bash
确保可以切换nova用户
su - nova
设置开机启动
systemctl enable openstack-nova-compute.service neutron-openvswitch-agent.service openvswitch.service
启动服务
systemctl start openstack-nova-compute.service neutron-openvswitch-agent.service openvswitch.service
设置
ovs-vsctl show
ovs-vsctl add-br br-int
ovs-vsctl add-br br-bond0
ovs-vsctl add-port br-bond0 bond0
创建openstack目录并拷贝nova文件
mkdir -p /data/openstack ; cp -a /var/lib/nova /data/openstack/
重启计算节点
reboot
