openstack部署
openstack kvm宿主机的管理平台
创建的虚拟机都是链接克隆
支持多用户，自定义网络 vpc
1. 服务介绍
nova：提供计算资源
glance：镜像服务（已经安装好操作系统的磁盘文件）
neutron：网络服务（提供网络连接）
cinder：块存储服务（云硬盘）
cellometer：监控计费
keystone：认证服务，openstack账号密码
horizon：dashboard服务，web管理界面
swift：对象存储
heat：编排服务，定义yaml文件，批量启动vm
2. openstack部署
（1）环境准备
| ip | name |
| 10.0.0.11 | controller |
| 10.0.0.21 | compute1 |
部署好两台机器，将名称和ip配置好
然后各自hosts添加解析
（2）准备包
chinaskills_cloud_iaas
CentOS-7-x86_64-DVD-2003
（3）安装前准备
systemctl stop firewalld
systemctl disable firewalld
setenforce 0
vim /etc/selinux/config
SELINUX=permissive # 修改该行将上述包上传到controller和compute上，并执行以下命令挂载
mount -o loop CentOS-7-x86_64-DVD-2003.iso Centos7
mkdir /opt/openstack
cp -rf /mnt/* /opt/openstack/
umount /mnt/
mount -o loop CentOS-7-x86_64-DVD-2003.iso /mnt/
mkdir /opt/centos
cp -rp /mnt/* /opt/centos/
vim /etc/yum.repos.d/local.repo # 配置本地源
[centos]
name=centos
baseurl=file:///opt/centos
gpgcheck=0
enabled=1
[iaas]
name=iaas
baseurl=file:///opt/openstack/iaas-repo
gpgcheck=0
yum install -y vim vsftpd iaas-xiandian
# 修改vsftpd匿名访问
anonymous_enable=YES
anon_root=/opt/
###修改配置文件
