openstack 添加一个计算节点

1、修改hosts解析

vim /etc/hosts

10.0.0.11 controller
10.0.0.31 compute1

10.0.0.32 compute2

2、配置yum源

mount /dev/cdrom /mnt
上传openstack_rpm.tar.gz到/opt下解压
Vim /etc/yum.repos.d/local.repo
[local]
name=local
baseurl=file:///mnt
gpgcheck=0

[openstack]
name=openstack
baseurl=file:///opt/repo
gpgcheck=0

echo 'mount /dev/cdrom /mnt' >>/etc/rc.d/rc.locall
chmod +x /etc/rc.d/rc.local

3、时间同步

yum install chrony -y

server 10.0.0.11 iburst

启动

4、安装openstack客户端和openstack-selinux

 yum install openstack-selinux -y

yum install python-openstackclient -y

5、安装nova-compute

安装：yum install openstack-nova-compute -y

yum install  openstack-utils.noarch -y

查看虚拟化是否支持

启动

systemctl enable libvirtd.service openstack-nova-compute.service

systemctl start libvirtd.service openstack-nova-compute.service

6、安装neutron-linuxbrige-agent

yum install openstack-neutron-linuxbridge ebtables ipset -y
