准备工作：
VMware Workstation Pro 虚拟机 我使用版本：15.5.2 build-15785246
CentOS-7-x86_64-DVD-1511.iso
XianDian-IaaS-v2.2.iso
补上需要的两个镜像
虚拟机配置 (controller和compute配置相同)：
内存 3G
处理器 2G
硬盘 50G
CD/DVD CentOS-7-x86_64-DVD-1511.iso
网络适配器 VMnet1
网络适配器2 VMnet2
controller和compute网络配置
主机名 | VMnet1 | VMnet2 |
controller | 192.168.28.10 | 192.168.128.10 |
compute | 192.168.28.20 | 192.168.128.20 |
controller改主机名字，关防火墙，设置主机映射开启虚拟机
hostnamectl set-hostname controller
systemctl stop firewalld
systemctl disable firewalld
setenforce 0
sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config
cat >>/etc/hosts<<eof
192.168.28.10 controller
192.168.28.20 compute
eofcompute
hostnamectl set-hostname compute
systemctl stop firewalld
systemctl disable firewalld
setenforce 0
sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config
cat >>/etc/hosts<<eof
192.168.28.10 controller
192.168.28.20 compute
eofcontroller
接下来，进入opt目录，创建挂载点 centos 以及 iaas，并使用CRT将xiandian镜像传入opt目录下
cd /opt
mkdir centos iaas设置开机自动挂载镜像文件
cat >>/etc/fstab<<eof
/dev/cdrom /opt/centos iso9660 defaults 0 0
/opt/XianDian-IaaS-v2.2.iso /opt/iaas iso9660 defaults 0 0
eof挂载立即生效
mount -a进入 /etc/yum.repos.d 目录，删除或移动里面的大写C开头的文件，否则后面会造成缓存错误，载创建repo源文件
cd /etc/yum.repos.d
mkdir bk
mv C* bk
cat >>/etc/yum.repos.d/local.repo<<eof
[centos]
name=centos
baseurl=file:///opt/centos
gpgcheck=0
enabled=1
[iaas]
name=iaas
baseurl=file:///opt/iaas/iaas-repo
gpgcheck=0
enabled=1
eof清除缓存，生成缓存
yum clean all
yum makecache出现提示，说明是成功了（不需要和我的完全一摸一样，因为iso版本的不同，生成的缓存也不同）
[root@controller ~]# yum makecache

Determining fastest mirrors
元数据缓存已建立注意，如果出现 下面展示 的段落信息，说明你之前的步骤出错了，可能是yum源没配置好，也可能是没挂载好，这里很坑
[root@compute yum.repos.d]# yum makecache
已加载插件：fastestmirror
One of the configured repositories failed (未知),
and yum doesn't have enough cached data to continue. At this point the only
safe thing yum can do is fail. There are a few ways to work "fix" this:
1. Contact the upstream for the repository and get them to fix the problem.
2. Reconfigure the baseurl/etc. for the repository, to point to a working
upstream. This is most often useful if you are using a newer
distribution release than is supported by the repository (and the
packages for the previous distribution release still work).
3. Disable the repository, so yum won't use it by default. Yum will then
just ignore the repository until you permanently enable it again or use
--enablerepo for temporary usage:
yum-config-manager --disable <repoid>
4. Configure the failing repository to be skipped, if it is unavailable.
Note that yum will try to contact the repo. when it runs most commands,
so will have to try and fail each time (and thus. yum will be be much
slower). If it is a very temporary problem though, this is often a nice
compromise:
yum-config-manager --save --setopt=<repoid>.skip_if_unavailable=true
Cannot find a valid baseurl for repo: centos如果是出现了 /var/run/yum.pid 的消息
执行下面这段命令即可
rm -rf /var/run/yum.pid接下来安装vsftpd和iaas-xiandian
yum install iaas-xiandian vsftpd -y在controller上安装 ftp（文件传输）服务
增加匿名访问
cat >>/etc/vsftpd/vsftpd.conf<<eof
anon_root=/opt
eof
systemctl restart network
systemctl start vsftpd
systemctl enable vsftpd接下来配置xiandian的openrc.sh应答文件（一个字都不能错）
sed -i 's/.//' /etc/xiandian/openrc.sh
sed -i 's/PASS=/PASS=000000/g' /etc/xiandian/openrc.sh
sed -i 's/HOST_IP=/HOST_IP=192.168.28.10/g' /etc/xiandian/openrc.sh

sed -i 's/INTERFACE_NAME=/INTERFACE_NAME=ens34/g' /etc/xiandian/openrc.sh接着使用命令 cat /etc/xiandian/openrc.sh 查看配置文件，配置完后，应如下图

元数据缓存已建立下载 iaas-xiandain 进入 /etc/xiandian ，将openrc.sh 改名为openrc.sh.bk 备份 以防出现错误
再将 controller(192.168.28.10)中的 /etc/xiandian/openrc.sh 文件传输到 本机
yum -y install iaas-xiandian
cd /etc/xiandian
mv openrc.sh openrc.sh.bk
scp 192.168.28.10:/etc/xiandian/openrc.sh openrc.sh执行安装脚本
两个节点均执行初始化脚本
iaas-pre-host.sh注意：执行需要一段时间，不要去按回车什么的了，在出现 【reboot】提示后，必须重启，否则之后的实例发不出去，问题很大！！！
两台均重启
reboot重新启动虚拟机
