59.IaaS平台实战①

任务一、IaaS云平台搭建（15分）
修改云平台IaaS各节点的系统配置，按云平台搭建步骤逐步安装，并完成相应的答题。
1.操作系统环境配置（1分）
按以下要求设置主机名、防火墙及SELinux：
（1）设置控制节点主机名为controller，计算节点主机名为compute；
（2）关闭控制节点和计算节点的防火墙，设置开机不启动；
（3）设置控制节点和计算节点的SELinux为Permissive模式；
（4）退出SecureCRT，重新通过ssh连接各节点服务器；
使用命令查询控制节点和计算节点的主机名、防火墙是否处于关闭状态及SELinux的状态。以文本形式依次将命令行及查询信息提交到答题框。
[root@controller~]#hostname

Active:inactive(dead)
Docs:man:firewalld(1)
[root@controller~]#getenforce
Permissive
2.上传镜像源并挂载（1分）
通过SecureFX上传两个镜像文件CentOS-7-x86_64-DVD-1511.iso和XianDian-IaaS-v2.2.iso到控制节点的opt目录下；在opt目录下创建两个子目录centos和iaas，并将镜像文件对应挂载到上述两个目录下；使用df命令查看挂载的信息（需显示挂载的文件系统类型）。依次将操作命令及执行结果以文本形式提交到答题框。
[root@controller~]#mkdir/opt/{centos，iaas}
[root@controller~]#mount-oloopCentOS-7-x86_64-DVD-1511.iso/opt/centos/

2.nova管理（3分）
登录192.168.100.10/dashboard界面，创建一个名字为migration，flavor使用m1.medium，镜像使用centos7的云主机。查看该云主机的详细信息，并将该云主机冷迁移到另一个计算节点（controller节点既是控制节点也是计算节点，compute节点为计算节点，若原来在compute节点，则迁移到controller，反之亦然。云主机原来所在的节点我们称之为源节点，迁移过去的节点称之为目标节点。）最后将迁移的云主机启动并查看是否迁移了。将上述操作命令和返回结果以文本形式提交到答题框，先提交源节点的操作命令，后提交目标节点的操作命令。
