openstack 搭建詳細步驟

一、openstack單點部署

1、配置虛擬機NAT網絡連接

查看vmware的NAT網絡默認配置

|   |   |
| --- | --- |
|   | vmwarestation軟件點擊 上方“編輯”，選擇“虛擬網絡編輯器” |
|   | 找到vmnet10，是NAT模式，子網地址是172.25.2.0,子網掩碼是：255.255.255.0. |
|   | 再點擊“NAT設置”，可看到它的網關:172.25.2.2 |

配置當前虛擬機的網絡配置

|   |   |
| --- | --- |
|   | vmwarestation軟件點擊 上方“虛擬機”，選擇“設置”； |
|   | 首先沒有NAT網卡的，點擊“添加”，添加一個新的網絡適配器。 |
|   | 已經創建號NAT網卡的，進行如下配置： |
|   | 網絡連接模式改為："自定義（U）：特定虛擬網絡" |
|   | 在下拉選項中，選中“VMnet10(NAT模式)” |

配置linux網絡

|   |   |
| --- | --- |
|   |# 進入網絡配置目錄 |
|   |cd/etc/sysconfig/network-scripts |
|   |# 編輯nat網卡的配置 |
|   | vi ifcfg-ens33 |
|   |# 修改或添加如下信息： |
|   | BOOTPROTO=static |
|   | ONBOOT=yes|
|   | IPADDR=172.25.2.101 |
|   | NETMASK=255.255.255.0 |
|   | GATEWAY=172.25.2.2 |
|   | DNS=8.8.8.8 |
|   |   |
|   |# 在vi編輯器中,輸入:wq進行保存退出 |
|   | vi /etc/resolv.conf |
|   | 加入： |
|   | nameserver 8.8.8.8 |
|   | 輸入:wq進行保存退出 |
|   |   |
|   |# 關閉防火墻 |
|   | systemctl stop firewalld.service |
|   | systemctldisablefirewalld.service |
|   |   |
|   |# 重啟網絡 |
|   | systemctl restart network |
|   |   |
|   |# 測試 |
|   | ping www.baidu.com |

2、yum源配置

|   |   |
| --- | --- |
|   |# 關閉網絡管理 |
|   | systemctldisableNetworkManager |
|   |# 關閉selinux，修改文件為disabled |
|   | sed -i's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config |
|   |# selinux修改生效 |
|   | setenforce 0 |
|   |   |
|   |##################################更新yum源################################# |
|   |# 將官方的yum源備份到一個新目錄： |
|   |mkdir/etc/yum.repos.d/repo.bak/ |
|   |mv/etc/yum.repos.d/*.repo repo.bak/ |
|   |   |
|   |# 更新下載阿里源 |
|   | curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo |
|   |   |
|   |# 清理yum |
|   | yum clean all |
|   | yum makecache |
|   |   |
|   |# 更新yum信息 |
|   | yum update -y |
|   |   |
|   |# 查看當前存在的openstack版本安裝源 |
|   | yum list | grep openstack |
|   |   |
|   |# 安裝安裝源 |
|   | yum install -y centos-release-openstack-queens |
|   |   |
|   |# 調整倉庫配置文件 |
|   | vi /etc/yum.repos.d/CentOS-QEMU-EV.repo |
|   |# 將文件中/$contentdir/改為/centos-7/ |
|   |   |
|   |# 添加epel-repo源 |
|   | curl -o /etc/yum.repos.d/epel-7.repo http://mirrors.aliyun.com/repo/epel-7.repo |
|   |   |
|   |# 添加openstack.queens.repo文件信息 |
|   |cat> /etc/yum.repos.d/openstack-queens.repo <

	

	二、國賽雙節點部署

	1、準備虛擬機

	
|   |   |
| --- | --- |
|   | 創建虛擬機前，創建好vmnet2(僅主機模式),vmnet10(NAT模式)網卡，檢查對應的適配器是否創建成功。 |
|   | 準備兩臺vmware虛擬機，手動最小化安裝2臺Centos7.2系統，第一個網卡為僅主機模式，第二個網卡為NAT模式，配置CPU虛擬機，4G以上內存，50G以上硬盤。 |

	

	master節點網卡：

	
|   |   |
| --- | --- |
|   |TYPE=Ethernet |
|   |BOOTPROTO=static |
|   |DEFROUTE=yes|
|   |PEERDNS=yes|
|   |PEERROUTES=yes|
|   |IPV4_FAILURE_FATAL=no|
|   |IPV6INIT=yes|
|   |IPV6_AUTOCONF=yes|
|   |IPV6_DEFROUTE=yes|
|   |IPV6_PEERDNS=yes|
|   |IPV6_PEERROUTES=yes|
|   |IPV6_FAILURE_FATAL=no|
|   |NAME=eno16777736 |
|   |UUID=f34abd2e-89c9-4daf-a28c-54765164d59d |
|   |DEVICE=eno16777736 |
|   |ONBOOT=yes|
|   |IPADDR=192.168.16.10|
|   |NETMASK=255.255.255.0|

	

	Node節點網卡：

	
|   |   |
| --- | --- |
|   |TYPE=Ethernet |
|   |BOOTPROTO=static |
|   |DEFROUTE=yes|
|   |PEERDNS=yes|
|   |PEERROUTES=yes|
|   |IPV4_FAILURE_FATAL=no|
|   |IPV6INIT=yes|
|   |IPV6_AUTOCONF=yes|
|   |IPV6_DEFROUTE=yes|
|   |IPV6_PEERDNS=yes|
|   |IPV6_PEERROUTES=yes|
|   |IPV6_FAILURE_FATAL=no|
|   |NAME=eno16777736 |
|   |UUID=8bbcc106-d60f-48cc-aafd-2bde0154fa2e |
|   |DEVICE=eno16777736 |
|   |ONBOOT=yes|
|   |IPADDR=192.168.16.20|
|   |NETMASK=255.255.255.0|

	

	2、鏡像掛載

	鏡像上傳到master節點，然后完成掛載即可。

	
|   |   |
| --- | --- |
|   |# 掛載linux鏡像 |
|   |cd/root/; |
|   | mount -o loop CentOS-7-x86_64-DVD-1511.iso /mnt/; |
|   |mkdir/opt/centos7.2; |
|   |cp-rvf /mnt/* /opt/centos7.2/ |
|   | umount /mnt/; |
|   |   |
|   |# 掛載iaas鏡像 |
|   |cd/root/; |
|   | mount -o loop XianDian-IaaS-v2.2.iso /mnt/; |
|   |mkdir/opt/iaas; |
|   |cp-rvf /mnt/* /opt/iaas; |
|   | umount /mnt/; |

	

	3、本地yum配置

	分別配置控制節點和計算節點的yum

	
|   |   |
| --- | --- |
|   |# 控制節點： |
|   | rm -rf /etc/yum.repos.d/CentOS-*; |
|   | cat > /etc/yum.repos.d/local.repo <
|   |   |
| --- | --- |
|   |# 計算節點：(如果沒有可以后面再配) |
|   | rm -rf /etc/yum.repos.d/CentOS-*; |
|   | cat > /etc/yum.repos.d/local.repo << EOF |
| ? ? | [centos] |
| ? ? | name=centos |
| ? ? | baseurl=ftp://192.168.16.10/centos7.2 |
| ? ? | gpgcheck=0 |
| ? ? | enabled=1 |
| ? ? | [iaas] |
| ? ? | name=iass |
| ? ? | baseurl=ftp://192.168.16.10/iaas/iaas-repo |
| ? ? | gpgcheck=0 |
| ? ? | enabled=1 |
| ? ? | EOF |

	

	為計算節點提供ftp訪問方式

	
|   |   |
| --- | --- |
|   |# 控制節點——yum緩存清理 |
|   | yum clean all |
|   | yum makecache |
|   |   |
|   |# 控制節點——安裝vsftpd和ftp |
|   | yum install -y vsftpd |
|   | yum install -y ftp |
|   | rpm -qa| grep vsftpd |
|   |   |
|   |# 控制節點——修改vsftpd配置文件 |
|   | 在/etc/vsftpd/vsftpd.conf中添加一行代碼： |
|   | anon_root=/opt |
|   |   |
|   |# 控制節點——安裝網絡工具包 |
|   | yum install net-tools |
|   |   |
|   |# 重啟vsftpd服務 |
|   | systemctl restart vsftpd |
|   |# 開機啟動vsftpd |
|   | systemctlenablevsftpd |
|   |   |
|   |# 控制節點、計算節點——關閉防火墻 |
|   | setenforce 0; |
|   | iptables -F; |
|   | iptables -X; |
|   | iptables -Z; |
|   | systemctl stop firewalld; |
|   | systemctldisablefirewalld; |
|   |   |
|   |# 計算節點 |
|   | yum clean all |
|   | yum makecache |

	

	4、給計算節點（node）添加新磁盤并分區

	在vmware上給計算節點虛擬機添加一個新磁盤

	虛擬機——> 設置——> 添加——> 硬盤——> scsi模式——> 創建新虛擬磁盤——> 20G，拆分為多個文件——> 完成

	
|   |   |
| --- | --- |
|   |# 重啟計算節點虛擬機 |
|   | reboot |
|   |   |
|   |# 查看當前虛擬機的磁盤情況 |
|   | fdisk -l |
|   |# 可以看到Disk /dev/sdb: 21.5 GB是完全空閑的 |
|   |   |
|   |# 創建兩個空白磁盤空間 |
|   | fdisk /dev/sdb |
|   | n,p,回車,回車,+10G |
|   | n,p,回車,回車,回車 |
|   | w  |

	

	5、在controller和compute節點安裝iaas-xiandian包

	
|   |   |
| --- | --- |
|   |# 控制節點、計算節點分別執行，安裝軟件包 |
|   | yum install -y iaas-xiandian |

	

	控制節點、計算節點編輯修改配置文件/etc/xiandian/openrc.sh

	1、創建鏡像

	
|   |   |
| --- | --- |
|   |# 控制節點上，找到qcow2鏡像 |
|   | [root@controller ~]#cd/opt/iaas/images/ |
|   | [root@controller images]#ls|
|   | CentOS_6.5_x86_64_XD.qcow2 CentOS_7.2_x86_64_XD.qcow2 MySQL_5.6_XD.qcow2 |
|   |   |
|   |# 上傳鏡像致Glance服務 |
|   |# 在控制節點，通過glance命令，將qcow2鏡像上傳到平臺 |
|   | [root@controller images]#source/etc/keystone/admin-openrc.sh |
|   | [root@controller images]# glance image-create --name"centos7.2"--disk-format qcow2 --container-format bare --progress < CentOS_7.2_x86_64_XD.qcow2 |

	五、Nova組件詳解

	計算節點通過Nova Computer進行虛擬機創建，通過libvirt調用kvm創建虛擬機，nova之間通信通過rabbitMQ隊列進行通信。

	Nova位于Openstack架構的中心，其他服務或者組件（比如Glance、Cinder、Neutron等）對它提供支持，另外它本身的架構也比較復雜。

	作用：

	?

	1. Nova是OpenStack最核心的服務模塊，負責管理和維護云計算環境的計算資源，負責整個云環境虛擬機生命周期的管理。

	?

	2. Nova是OpenStack的計算服務，負責維護和管理的網絡和存儲，提供計算服務。
