环境准备
两个主机：控制（controller：192.168.100.10）节点和计算（compute:192.168.100.20）节点
两张网卡：一个100网段，一个200网段（使用服务器则插两跟线，安装centos）
硬盘配置：（服务器使用raid5）
控制节点硬盘分区
计算节点的硬盘分区
安装OpenStack
一、修改主机名
192.168.100.10是控制节点
[root@localhost ~]# hostnamectl set-hostname controller
[root@localhost ~]# bash
[root@controller ~]#
192.168.100.20是计算节点
[root@localhost ~]# hostnamectl set-hostname compute
[root@localhost ~]# bash
[root@compute ~]#
二、配置yum源
在控制节点执行：
把原先的yum源移走，再把先点和centos的镜像挂载到/opt下，
[root@controller ~]# mv /etc/yum.repos.d/* /media/
[root@controller ~]# mkdir /opt/{centos,iaas}
[root@controller ~]# echo /root/CentOS-7-x86_64-DVD-1511.iso /opt/centos/ iso9660 loop 0 0 >> /etc/fstab
[root@controller ~]# echo /root/XianDian-IaaS-v2.2.iso /opt/iaas/ iso9660 loop 0 0 >> /etc/fstab
[root@controller ~]# mount -a
编写yum源文件
[root@controller ~]# 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
~
~
~
"/etc/yum.repos.d/local.repo" 11L, 143C
清除缓存重新加载一下yum源
[root@controller ~]# yum clean all
Loaded plugins: fastestmirror
Cleaning repos: centos iaas
Cleaning up everything
Cleaning up list of fastest mirrors
[root@controller ~]# yum repolist
Loaded plugins: fastestmirror
centos | 3.6 kB 00:00:00
iaas | 2.9 kB 00:00:00
(1/3): centos/group_gz | 155 kB 00:00:00
(2/3): centos/primary_db | 2.8 MB 00:00:00
(3/3): iaas/primary_db | 2.3 MB 00:00:00
Determining fastest mirrors
repo id repo name status
centos centos 3,723
iaas iaas 1,688
repolist: 5,411
三、关闭防火墙
在控制节点和计算节点都执行
systemctl disable --now firewalld
setenforce 0
四、控制节点安装配置ftp，和计算节点分享yum源
[root@controller ~]# yum install vsftpd -y
[root@controller ~]# echo anon_root=/opt >> /etc/vsftpd/vsftpd.conf
[root@controller ~]# systemctl enable --now vsftpd
ftp的21端口开启则说明ftp安装成功（若是命令不可以使用则需要安装服务，命令：yum install net-tools -y）
[root@controller ~]# netstat -ntpl
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name
tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 1462/sshd
tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN 2223/master
tcp6 0 0 :::21 :::* LISTEN 3117/vsftpd
tcp6 0 0 :::22 :::* LISTEN 1462/sshd
tcp6 0 0 ::1:25 :::* LISTEN 2223/master
配置计算节点的yum源
计算节点执行
将原先的yum源移走
[root@compute ~]# mv /etc/yum.repos.d/* /media/
在编写yum文件
[root@compute ~]# vi /etc/yum.repos.d/local.repo
[centos]
name=centos
baseurl=ftp://192.168.100.10/centos
gpgcheck=0
enabled=1
[iaas]
name=iaas
baseurl=ftp://192.168.100.10/iaas/iaas-repo
gpgcheck=0
enabled=1
看一下是否成功
[root@compute ~]# yum clean all
Loaded plugins: fastestmirror
Cleaning repos: centos iaas
Cleaning up everything
Cleaning up list of fastest mirrors
[root@compute ~]# yum repolist
Loaded plugins: fastestmirror
centos | 3.6 kB 00:00:00
iaas | 2.9 kB 00:00:00
(1/3): centos/group_gz | 155 kB 00:00:00
(2/3): centos/primary_db | 2.8 MB 00:00:00
(3/3): iaas/primary_db | 2.3 MB 00:00:00
Determining fastest mirrors
repo id repo name status
centos centos 3,723
iaas iaas 1,688
repolist: 5,411
出现了centos和iaas和控制节点一样说明yum源可以了
五、计算节点磁盘分区
计算节点执行
[root@compute ~]# parted /dev/sda
进入分区后再（parted）后面输入p可以查看分区情况，然后输入一下命令进行分区
mkpart cinder 3239G 3339G
mkpart swift 3339G 3439G
输入q退出
查看一下分区
[root@compute ~]# lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 3.7T 0 disk
├─sda1 8:1 0 1M 0 part
├─sda2 8:2 0 500M 0 part /boot
├─sda3 8:3 0 3T 0 part
│ ├─centos-root 253:0 0 3T 0 lvm /
│ └─centos-swap 253:1 0 16G 0 lvm [SWAP]
├─sda4 8:4 0 93.2G 0 part
└─sda5 8:5 0 93.1G 0 part
六、安装先点和配置文件
两个节点都安装
yum install -y iaas-xiandian
先点的配置文件目录是：/etc/xiandian/openrc.sh
先把配置文件中的注释#号去掉
以下在控制节点执行
[root@controller ~]# sed -i "s/^#//" /etc/xiandian/openrc.sh
编辑配置文件
[root@controller ~]# vi /etc/xiandian/openrc.sh

检查一下，避免写错了
[root@controller ~]# egrep -v '^$|^#' /etc/xiandian/openrc.sh
HOST_IP=192.168.100.10
HOST_NAME=controller
HOST_IP_NODE=192.168.100.20

检查没有问题，可以远程复制给计算节点
[root@controller ~]# scp /etc/xiandian/openrc.sh compute:/etc/xiandian/openrc.sh
接下来，换到计算节点修改以下配置文件
主要是把网卡修改成计算节点的200网段网卡
我的是这样的
[root@compute ~]# egrep -v '^$|^#' /etc/xiandian/openrc.sh
HOST_IP=192.168.100.10
HOST_NAME=controller
HOST_IP_NODE=192.168.100.20

七、开始跑脚本
两个节点都执行
控制节点
[root@controller ~]# iaas-pre-host.sh
计算节点
[root@compute ~]# iaas-pre-host.sh
执行后
看一下脚本
[root@controller ~]# ll /usr/local/bin
total 128

-rwxr-xr-x. 1 root root 3337 Nov 5 2017 iaas-uninstall-all.sh
控制节点执行
安装mysql
[root@controller ~]# iaas-install-mysql.sh
[root@controller ~]# iaas-install-keystone.sh && iaas-install-glance.sh && iaas-install-nova-controller.sh
在控制节点查看有这四个用户
[root@controller ~]# source /etc/keystone/admin-openrc.sh
[root@controller ~]# openstack user list
+----------------------------------+--------+
| ID | Name |
+----------------------------------+--------+
| 7fcdbb81f75c440080d2236dda784987 | glance |
| ae6a2ec279434a48a4dfd0dd885d80fa | nova |

| c678293c2f1f4db9bd8a059a8bc81cf3 | admin |
+----------------------------------+--------+
[root@controller ~]#
就可以在计算节点跑nova脚本
计算节点执行
[root@compute ~]# iaas-install-nova-compute.sh
netureon服务
控制节点执行
[root@controller ~]# iaas-install-neutron-controller.sh
在计算节点执行
[root@compute ~]# iaas-install-neutron-compute.sh
控制节点
[root@controller ~]# iaas-install-neutron-controller-gre.sh
计算节点
[root@compute ~]# iaas-install-neutron-compute-gre.sh

[root@compute ~]# iaas-install-swift-compute.sh
计算节点会出现如下询问，输入yes在输入控制节点的密码
ceilometer服务
控制节点
[root@controller ~]# iaas-install-ceilometer-controller.sh
等他执行完在执行计算节点
计算节点
[root@compute ~]# iaas-install-ceilometer-compute.sh
控制节点
[root@controller ~]# iaas-install-alarm.sh && iaas-install-heat.sh
安装trove服务
（安装Trove服务之前需要配置好网络（flat或gre）,创建好子网，并确认系统已经安装swift和cinder两个服务，否则安装会失败。）
控制节点
编写一下脚本
[root@controller ~]# vi /usr/local/bin/iaas-install-trove.sh
这个主要在web页面创建一个
1、创建外网
登录平台
域是： demo
用户名：admin
密码： 000000
在系统的网络界面里，点击创建网络
按照下面的填写然后提交，不要忘了点击外部网络
创建子网
点击创建子网
按照下图的填写，然后下一步
填写分配池
出现成功即表示创建成功
2、创建内网
3、在创建一个网络
在创建子网
3、创建路由
按照图片填入，然后新建路由
点击
4、配置安全组
把全部的规则都删除
重新添加规则
规则添加所有的ICMP协议，点击添加
入口方向按照以上同样的方式在添加所有的TCP协议和UDP协议
添加完后如图
在添加出口的
同样，ICMP、TCP、UDP协议的全部添加
创建完网络后回到命令界面查看网络列表
int开头的是内部网络，ext开头的是外部网络
[root@controller ~]# source /etc/keystone/admin-openrc.sh
[root@controller ~]#
[root@controller ~]# openstack network list
+-------------------------+----------+--------------------------+
| ID | Name | Subnets |
+-------------------------+----------+--------------------------+

| -b7ca-12cc2543c6f0 | | c8847f78b10a |
+-------------------------+----------+--------------------------+
[root@controller ~]#
然后配置trove脚本
[root@controller ~]# vi /usr/local/bin/iaas-install-trove.sh
#!/bin/bash
source /etc/xiandian/openrc.sh
source /etc/keystone/admin-openrc.sh

break
fi
done
# elif [[ $network_mode == 'vlan' ]] ;then
# echo 'vlan'
fi
fi
"/usr/local/bin/iaas-install-trove.sh" 176L, 11524C written
然后执行脚本
控制节点
[root@controller ~]# iaas-install-trove.sh
执行完后修改控制节点的先点文件
[root@controller ~]# vi /etc/xiandian/openrc.sh
#--------------------system Config--------------------##
#Controller Server Manager IP. example:x.x.x.x

"/etc/xiandian/openrc.sh" 113L, 3047C written
控制节点执行命令
[root@controller ~]# iaas-install-nova-compute.sh
[root@controller ~]# setenforce 0
到这里全部安装完成
