2 设置网络、主机名

---

修改和添加/etc/sysconfig/network-scripts/ifcfg-enp*（具体的网口）文件。
（1）controller节点
设置网络：
enp8s0: 192.168.100.10
DEVICE=enp8s0
TYPE=Ethernet
ONBOOT=yes
NM_CONTROLLED=no
BOOTPROTO=static
IPADDR=192.168.100.10
PREFIX=24
GATEWAY=192.168.100.1
enp9s0: 192.168.200.10
DEVICE=enp9s0
TYPE=Ethernet
ONBOOT=yes
NM_CONTROLLED=no
BOOTPROTO=static
IPADDR=192.168.200.10
PREFIX=24
设置主机名：
hostnamectl set-hostname controller

按ctrl+d 退出 重新登陆
（2）compute 节点
设置网络：
enp8s0: 192.168.100.20
DEVICE=enp8s0
TYPE=Ethernet
ONBOOT=yes
NM_CONTROLLED=no
BOOTPROTO=static
IPADDR=192.168.100.20
PREFIX=24
GATEWAY=192.168.100.1
enp9s0: 192.168.200.20
DEVICE=enp9s0
TYPE=Ethernet
ONBOOT=yes
NM_CONTROLLED=no
BOOTPROTO=static
IPADDR=192.168.200.20
PREFIX=24
设置主机名：
hostnamectl set-hostname compute

按ctrl+d 退出 重新登陆
3 设置yum源

---

#Controller和compute节点
（1）yum源备份
#rm -rf /etc/yum.repos.d/*
（2）创建repo文件
【controller】
在/etc/yum.repos.d创建centos.repo源文件
vi /etc/yum.repos.d/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
【compute】
在/etc/yum.repos.d创建centos.repo源文件
vi /etc/yum.repos.d/local.repo

[root@compute ~]# vi /etc/yum.repos.d/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
主机名映射
[root@controller ~]# vi /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.100.10 controller
192.168.100.20 compute
[root@compute ~]# vi /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.100.10 controller
192.168.100.20 compute
（3）挂载iso文件
【挂载CentOS-7-x86_64-DVD-1804.iso】
[root@controller ~]# mount -o loop CentOS-7-x86_64-DVD-1804.iso /mnt/
[root@controller ~]# mkdir /opt/centos
[root@controller ~]# mkdir /opt/iaas
[root@controller ~]# cp -rvf /mnt/* /opt/centos/
[root@controller ~]# umount /mnt/
【挂载XianDian-IaaS-v2.4.iso】
[root@controller ~]# mount -o loop chinaskills_cloud_iaas.iso /mnt/
mount: /dev/loop0 is write-protected, mounting read-only
[root@controller ~]# cp -rvf /mnt/* /opt/iaas
（4）搭建ftp服务器，开启并设置自启
[root@controller ~]# yum install vsftpd -y
[root@controller ~]# vi /etc/vsftpd/vsftpd.conf
添加anon_root=/opt/
生存退出
[root@controller ~]# systemctl start vsftpd
[root@controller ~]# systemctl enable vsftpd
（5）设置防火墙和Selinux
【controller/compute】
编辑selinux文件
vi /etc/selinux/config

SELINUX=permissive
[root@controller ~]# setenforce 0
关闭防火墙并设置开机不自启
systemctl stop firewalld.service

systemctl disable firewalld.service

（6）打扫缓存，验证yum源
【controller/compute】
yum clean all

yum list

4 编辑环境变量

---

controller和compute节点

yum install iaas-xiandian -y

编辑文件/etc/xiandian/openrc.sh,此文件是安装过程中的各项参数，根据每项参数上一行的阐明及服务器实际环境举行设置。

5 通过脚本安装私有云平台

---

以下脚本按顺序实行！
Controller:
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-dashboard.sh
iaas-install-cinder-controller.sh
iaas-install-swift-controller.sh
iaas-install-nova-compute.sh(修改设置之后运行)
Compute:
iaas-pre-host.sh
reboot
iaas-install-nova-compute.sh
iaas-install-neutron-compute.sh
iaas-install-cinder-compute.sh
iaas-install-swift-compute.sh
6 创建云主机

---

流程：
（1）管理员->资源管理->云主机范例->创建云主机范例
（2）管理员->网络->网络->创建网络
（2）项目->网络->安全组->管理规则->添加规则（ICMP、TCP、UDP）
（3）项目->资源管理->云主机->创建云主机
7 云平台创建云主机

---

1 创建云主机范例

2 创建云主机网络

选择vlan模式，网络要和外网网卡一个网段，段ID要选择外网网卡地点网段

2.1绑定固定网络

3 修改安全组

4 上传镜像
[root@controller ~]# source /etc/keystone/admin-openrc.sh
[root@controller ~]# glance image-create --name “CentOS7.5” --disk-format qcow2 --container-format bare --progress < /opt/iaas/images/CentOS_7.5_x86_64_XD.qcow2
[=============================>] 100%

5 创建云主机

6 测试毗连

8 Openstack下令创建云主机

---

1 创建云主机范例

使用下令创建一个名为 test ，ID为 6 ，内存为 2048MB ，磁盘为 10GB ，vcpu数量为 2 的云主机范例。
nova flavor-create test 6 2048 10 2
±—±-----±----------±-----±----------±-----±------±------------±----------±------------+
| ID | Name | Memory_MB | Disk | Ephemeral | Swap | VCPUs | RXTX_Factor | Is_Public | Description |

| 6 | test | 2048 | 10 | 0 | | 2 | 1.0 | True | - |
±—±-----±----------±-----±----------±-----±------±------------±----------±------------
2 创建云主机网络

思路：检察云平台创建好的网络，检察它的具体信息，用下令创建的时间，指定参数即可！
