搭建openstack平台（centos7+iaas）

centos7搭建openstack（iaas）

环境准备：

controller节点

1.2cpu，2g内存
2.双网卡，两块100g磁盘
3.opt目录下存有iaas源iso镜像

compute节点

1.2cpu，2g内存
2.双网卡，两块100g磁盘
3.opt目录下存有iaas源iso镜像

网卡	网段
eth0	192.168.10.0/24
eth1	192.168.20.0/24

配置：

第一步：配置IP

controller

hostnamectl set-hostname controller
vi /etc/sysconfig/network-scripts/ifcfg-eth0
vi /etc/sysconfig/network-scripts/ifcfg-eth1
vi /etc/hosts
setenforce 0
vi /etc/selinux/config
systemctl stop firewalld
systemctl disable firewalld
systemctl restart network

compute

hostnamectl set-hostname controller
vi /etc/sysconfig/network-scripts/ifcfg-eth0
vi /etc/sysconfig/network-scripts/ifcfg-eth1
vi /etc/hosts
setenforce 0
vi /etc/selinux/config
systemctl stop firewalld
systemctl disable firewalld
systemctl restart network

第二步：配置yum源

两台主机配置相同

mkdir -p /mnt/cdrom
mkdir -p /mnt/iaas
echo "/dev/cdrom /mnt/cdrom iso9660 defaults 0 0" >> /etc/fstab
echo "/opt/chinaskills_cloud_iaas.iso /mnt/iaas iso9660 defaults,loop 0 0" >> /etc/fstab
mount -a

cd /etc/yum.repos.d/
mkdir 1
mv * ./1
vi local.repo
	.......
yum clean all
yum makecache

第三步：安装xiandian并编辑配置文件

controller

yum -y install vim iaas-xiandian
vim /etc/xiandian/openrc.sh
	*/ctrl+v然后shift+g然后d，即可删除注释，然后i建编辑

compute

yum -y insall vim iaas-xiandian
scp controller:/etc/xiandian/openrc.sh /etc/xiandian/openrc.sh
vim /etc/xiandian/openrc.sh
	修改interface隧道接口IP为本机IP192.168.10.20

第四步：刷脚本配置

controller

iaas-pre-host.sh
然后重启
iaas-install-mysql.sh
iaas-install-keystone.sh
iaas-install-glance.sh
iaas-install-nova-controller.sh
iaas-install-neutron-controller.sh
iaas-install-dashboard.sh
iaas-install-cinder-controller.sh
iaas-insatll-swift-controller.sh

先刷完control节点再刷compute

compute

iaas-pre-host.sh
iaas-install-nova-compute.sh
iaas-install-neutron-compute.sh
iaas-install-cinder-compute.sh
iaas-insatll-swift-compute.sh

第五步：登录open stack
