搭建流程

1.配置网络，主机名（双节点）

controller：192.168.1.10 192.168.2.10
compute：192.168.1.20 192.168.2.20

controller配置：
[root@controller ~]# hostnamectl set-hostname controller
[root@controller ~]# logout
重连登录
[root@controller ~]# vi /etc/sysconfig/network-scripts/ifcfg-eno16777728 
TYPE=Ethernet

关机直接克隆compute
compute配置：
[root@compute ~]# hostnamectl set-hostname compute
[root@compute ~]# logout
重连登录
[root@compute ~]# vi /etc/sysconfig/network-scripts/ifcfg-eno16777728 
TYPE=Ethernet

    inet6 fe80::20c:29ff:fe01:7ec1/64 scope link 
       valid_lft forever preferred_lft forever

记得拉取两个镜像！！！（只需要在controller节点拉取）

2.永久闭防火墙和selinux（双节点）

[root@controller yum.repos.d]# systemctl stop firewalld
[root@controller yum.repos.d]# systemctl disable firewalld
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
Removed symlink /etc/systemd/system/basic.target.wants/firewalld.service.

[root@controller yum.repos.d]# setenforce 0
[root@controller yum.repos.d]# vi /etc/selinux/config 


# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#     enforcing - SELinux security policy is enforced.
#     permissive - SELinux prints warnings instead of enforcing.
#     disabled - No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of three two values:
#     targeted - Targeted processes are protected,
#     minimum - Modification of targeted policy. Only selected processes are protected. 
#     mls - Multi Level Security protection.
SELINUXTYPE=targeted 








[root@compute yum.repos.d]# systemctl stop firewalld
[root@compute yum.repos.d]# systemctl disable firewalld
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
Removed symlink /etc/systemd/system/basic.target.wants/firewalld.service.

[root@compute yum.repos.d]# setenforce 0
[root@compute yum.repos.d]# vi /etc/selinux/config 


# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#     enforcing - SELinux security policy is enforced.
#     permissive - SELinux prints warnings instead of enforcing.
#     disabled - No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of three two values:
#     targeted - Targeted processes are protected,
#     minimum - Modification of targeted policy. Only selected processes are protected. 
#     mls - Multi Level Security protection.
SELINUXTYPE=targeted

3.配置YUM源（双节点）

配置主机名映射
[root@controller ~]# vi /etc/hosts
192.168.1.10 controller
192.168.1.20 compute
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

[root@compute ~]# vi /etc/hosts
192.168.1.10 controller
192.168.1.20 compute
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6


[root@controller ~]# cd /etc/yum.repos.d/
[root@controller yum.repos.d]# rm -rf *
[root@controller yum.repos.d]# cat local.repo 
[centos]
name=centos
baseurl=file:///opt/centos
gpgcheck=0
enabled=1
[iaas]
name=iaas
baseurl=file:///opt/iaas/iaas-repo
gpgcheck=0
enabled=1


[root@compute ~]# cd /etc/yum.repos.d/
[root@compute yum.repos.d]# rm -rf *
[root@compute yum.repos.d]# cat local.repo 
[centos]
name=centos
baseurl=ftp://controller/centos
gpgcheck=0
enabled=1
[iaas]
name=iaas
baseurl=ftp://controller/iaas/iaas-repo
gpgcheck=0
enabled=1

4.写入/etc/fstab,并挂载镜像

[root@controller ~]# ls
anaconda-ks.cfg  CentOS-7-x86_64-DVD-1511.iso  XianDian-IaaS-v2.2.iso

[root@controller ~]# mkdir /opt/centos
[root@controller ~]# mkdir /opt/iaas

[root@controller ~]# cat /etc/fstab 

#

[root@controller ~]# mount -a
mount: /dev/loop0 is write-protected, mounting read-only
mount: /dev/loop1 is write-protected, mounting read-only

[root@controller ~]# df -h

[root@controller ~]# yum list
[root@controller ~]# yum install -y vim
[root@controller ~]# yum install -y vsftpd
[root@controller ~]# cat /etc/vsftpd/vsftpd.conf (在第一行添加下面内容，点点不用写)
anon_root=/opt/
...
...
[root@controller ~]# systemctl restart vsftpd
[root@controller ~]# systemctl enable vsftpd
Created symlink from /etc/systemd/system/multi-user.target.wants/vsftpd.service to /usr/lib/systemd/system/vsftpd.service.

5.安装iaas相关软件包

[root@controller ~]# yum install -y iaas-xiandian
[root@compute ~]# yum install -y iaas-xiandian

6.划分磁盘作为swift和cinder

[root@computer ~]# fdisk -l

8.配置NTP服务

安装ntp服务(时间同步)
（1）controller和compute节点
[root@controller ~]# yum -y install ntp
（2）配置controller节点
[root@controller ~]# vim /etc/ntp.conf
添加以下内容（删除默认sever规则）
server 127.127.1.0
fudge 127.127.1.0   stratum 10

[root@controller ~]# systemctl restart ntpd
[root@controller ~]# systemctl enable ntpd
Created symlink from /etc/systemd/system/multi-user.target.wants/ntpd.service to /usr/lib/systemd/system/ntpd.service.

（3）配置compute节点
[root@compute ~]# yum install -y ntp
[root@compute ~]# ntpdate controller
 1 Oct 08:36:16 ntpdate[2255]: adjust time server 192.168.1.10 offset -0.229334 sec
[root@compute ~]# systemctl enable ntpd
Created symlink from /etc/systemd/system/multi-user.target.wants/ntpd.service to /usr/lib/systemd/system/ntpd.service.

9.通过脚本安装服务

控制节点

iaas-pre-host.sh
reboot
iaas-install-mysql.sh
iaas-install-keystone.sh
iaas-install-glance.sh
iaas-install-nova-controller.sh
iaas-install-neutron-controller.sh
iaas-install-neutron-controller-gre.sh
iaas-install-dashboard.sh

计算节点
iaas-pre-host.sh
reboot
iaas-install-nova-compute.sh
iaas-install-neutron-compute.sh
iaas-install-neutron-compute-gre.sh

10.通过IP访问云平台

http://192.168.1.10/dashboard

11.测试

在这里插入图片描述
登录会有点卡
在这里插入图片描述

12.附录（用xshell连接虚拟机）

怎么用XSHELL连接虚拟机？
统一用桥接模式
1.查看本地wife属型（可以看出本地wife是192.168.1.0网段）
在这里插入图片描述
我拿controller节点举例子
1.设置网卡模式为桥接模式
在这里插入图片描述
2.配置IP和wife网段一致
也就是192.168.1.0网段
在这里插入图片描述
3.用xshell进行连接
在这里插入图片描述
4.连接成功
在这里插入图片描述

完成啦，记得一键三连哦！
