openstack云平台部署（详细+图文+bilibili视频）_openstack云平台搭建

一.准备工作

bilibili视频教学

openstack云平台搭建部署（内附有CSDN文章，并有关键内容讲解）

云平台需要两个节点，一个controller（控制节点），一个compute（计算节点）环境要求：VM虚拟机2台，镜像为centos7或7.5。

本指南使用的ip

控制节点(controller)：

一块100G的硬盘。两块网卡，两块网卡第一块网卡IP地址为192.168.100.10，第二块网卡IP地址为192.168.200.10。（编辑时用的是60G硬盘）

计算节点(compute)：

一块100G硬盘和一块50G硬盘。两块网卡第一块网卡IP地址为192.168.100.20，第二块网卡IP地址为192.168.200.20。（编辑时用的60G+20G两块硬盘）

本指南运用的镜像

1.通过百度网盘分享的文件：CentOS-7-x86_64-DVD-2009.iso
链接：https://pan.baidu.com/s/1VqYqutsstDwdt7w8g4tjjg 
提取码：dy7c 
2.通过百度网盘分享的文件：CentOS-7.5-x86_64-DVD-1804.iso
链接：https://pan.baidu.com/s/1pzt1_iZ0Lph69Llvo_2ILQ 
提取码：37ss 
3.通过百度网盘分享的文件：chinaskills_cloud_iaas.iso

提取码：2e16 

二.配置虚拟机

1.controller控制节点

注：以下步骤是为了把ens3*网卡更改为eth*网卡

重启后使用root登录，修改主机名，网卡

1.修改controller（控制节点）主机名

2.1修改第一块网卡

按insert进入编辑模式，编辑完后esc加冒号wq保存退出

2.2修改第二块网卡

重启网卡，使网卡生效

ip a查看一下是不是改好了

使用finalshell连接controller（为了更好的使用）

2.compute节点

第一块网卡配置如下：

第二块网卡配置如下：

重启网卡使配置生效

注意：compute节点也需要连接finalshell

三.正式开始搭建openstack云平台

controller节点配置：

1.上传centos7镜像和iaas镜像

上传成功！

2.关闭防火墙和selinux

systemctl stop firewalld #关闭防火墙systemctl disable firewalld #防火墙开机不自启动setenforce 0 #临时关闭selinux防火墙，1为打开getenforce #查看selinux状态

更改selinux配置文件，非临时性关闭

vi /etc/selinux/config

3.挂载镜像

[root@controller ~]# mount -o loop CentOS-7-x86_64-DVD-1804.iso /mnt/mount: /dev/loop0 写保护，将以只读方式挂载[root@controller ~]# mkdir /opt/centos[root@controller ~]# mkdir /opt/openstack[root@controller ~]# cp -rf /mnt/* /opt/centos/[root@controller ~]# umount /mnt/[root@controller ~]# mount -o loop chinaskills_cloud_iaas.iso /mnt/mount: /dev/loop0 写保护，将以只读方式挂载[root@controller ~]# cp -rf /mnt/* /opt/openstack[root@controller ~]# umount /mnt/

4.yum文件处理

 移除所有yum源

[root@controller ~]# cd /etc/yum.repos.d/[root@controller yum.repos.d]# mv * /media/[root@controller yum.repos.d]# ls[root@controller yum.repos.d]#

 写yum源文件

[root@controller yum.repos.d]# vi local.repo [root@controller yum.repos.d]# cat local.repo [centos]name=centosbaseurl=file:///opt/centosgpgcheck=0enabled=1[iaas]name=iaasbaseurl=file:///opt/openstack/iaas-repogpgcheck=0enabled=1

清理yum缓存，验证yum源是否成功，下载所需软件包

[root@controller yum.repos.d]# yum clean all #清除yum源缓存已加载插件：fastestmirror正在清理软件源： centos iaasCleaning up everythingMaybe you want: rm -rf /var/cache/yum, to also free up space taken by orphaned data from disabled or removed reposCleaning up list of fastest mirrors[root@controller yum.repos.d]# yum repolist #列出所有可用的yum源已加载插件：fastestmirrorDetermining fastest mirrorscentos | 3.6 kB 00:00:00 iaas | 2.9 kB 00:00:00 (1/3): centos/group_gz  | 166 kB 00:00:00 (2/3): centos/primary_db | 3.1 MB 00:00:00 (3/3): iaas/primary_db  | 1.4 MB 00:00:00 源标识  源名称  状态centos  centos  3,971iaas iaas 3,232repolist: 7,203[root@controller yum.repos.d]# yum install -y vim vsftpd iaas-xiandian #安装所需的软件包

5.配置vsftpd

vi /etc/vsftpd/vsftpd.conf

 

[root@controller yum.repos.d]# systemctl restart vsftpd #重启ftp服务[root@controller yum.repos.d]# systemctl enable vsftpd #设置ftp服务开机自启

 6.修改脚本

[root@controller ~]# vim /etc/xiandian/openrc.sh

在非插入模式下按下Ctrl+v-shift+g-D可删除注释符号

compute节点设置

1.关闭防火墙和selinux

[root@compute ~]# systemctl stop firewalld[root@compute ~]# systemctl disable firewalld[root@compute ~]# setenforce 0

更改selinux配置文件，非临时性关闭

vi /etc/selinux/config

2.硬盘分区

[root@compute ~]# fdisk /dev/sdb欢迎使用 fdisk (util-linux 2.23.2)。更改将停留在内存中，直到您决定将更改写入磁盘。使用写入命令前请三思。Device does not contain a recognized partition table使用磁盘标识符 0x34bc5373 创建新的 DOS 磁盘标签。命令(输入 m 获取帮助)：nPartition type: p primary (0 primary, 0 extended, 4 free) e extendedSelect (default p): Using default response p分区号 (1-4，默认 1)：起始 扇区 (2048-209715199，默认为 2048)：将使用默认值 2048Last 扇区, +扇区 or +size{K,M,G} (2048-209715199，默认为 209715199)：+10G分区 1 已设置为 Linux 类型，大小设为 10 GiB命令(输入 m 获取帮助)：nPartition type: p primary (1 primary, 0 extended, 3 free) e extendedSelect (default p): Using default response p分区号 (2-4，默认 2)：起始 扇区 (52430848-209715199，默认为 52430848)：将使用默认值 52430848Last 扇区, +扇区 or +size{K,M,G} (52430848-209715199，默认为 209715199)：+5G分区 2 已设置为 Linux 类型，大小设为 5 GiB命令(输入 m 获取帮助)：wThe partition table has been altered!Calling ioctl() to re-read partition table.正在同步磁盘。[root@compute ~]# lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTsda  8:0 0 200G 0 disk ├─sda1 8:1 0 1G 0 part /boot└─sda2 8:2 0 199G 0 part ├─centos-root 253:0 0 50G 0 lvm / ├─centos-swap 253:1 0 2G 0 lvm [SWAP] └─centos-home 253:2 0 147G 0 lvm /homesdb  8:16 0 100G 0 disk ├─sdb1 8:17 0 10G 0 part └─sdb2 8:18 0 5G 0 part sr0  11:0 1 4.2G 0 rom 

3.yum文件处理

移除源yum源

[root@compute ~]# cd /etc/yum.repos.d/[root@compute yum.repos.d]# mv * /media/

写入yum文件

[root@compute yum.repos.d]# vi local.repo[centos]name=centosbaseurl=ftp://192.168.100.10/centosgpgcheck=0enabled=1[iaas]name=iaasbaseurl=ftp://192.168.100.10/openstack/iaas-repogpgcheck=0enabled=1

清理yum缓存，验证yum是否可以用，下载所需软件包

[root@compute yum.repos.d]# yum clean all已加载插件：fastestmirror正在清理软件源： centos iaasCleaning up everythingMaybe you want: rm -rf /var/cache/yum, to also free up space taken by orphaned data from disabled or removed repos[root@compute yum.repos.d]# yum repolist已加载插件：fastestmirrorDetermining fastest mirrorscentos | 3.6 kB 00:00:00 iaas | 2.9 kB 00:00:00 (1/3): centos/group_gz  | 166 kB 00:00:00 (2/3): centos/primary_db | 3.1 MB 00:00:00 (3/3): iaas/primary_db  | 1.4 MB 00:00:00 源标识  源名称  状态centos  centos  3,971iaas iaas 3,232repolist: 7,203[root@compute yum.repos.d]# yum install -y vim iaas-xiandian

4.修改脚本

将controller节点的脚本复制至compute节点

[root@compute ~]# scp 192.168.100.10:/etc/xiandian/openrc.sh /etc/xiandian/openrc.sh The authenticity of host \'192.168.100.10 (192.168.100.10)\' can\'t be established.ECDSA key fingerprint is SHA256:3fUEo7XuafRBPMtY2rSnpjKOdGSrLnE68O2aZAXEp6o.ECDSA key fingerprint is MD5:4b:73:20:24:30:ad:6a:31:86:fa:26:55:47:92:99:cc.Are you sure you want to continue connecting (yes/no)? yesWarning: Permanently added \'192.168.100.10\' (ECDSA) to the list of known hosts.root@192.168.100.10\'s password: openrc.sh 100% 3820 1.9MB/s 00:00 

修改openrc.sh脚本中本机Ip地址

四.刷脚本

注：刷脚本前可以快照

controller节点：

[root@controller ~]# iaas-pre-host.sh #刷完该脚本后需要重启[root@controller ~]# iaas-install-mysql.sh[root@controller ~]# iaas-install-keystone.sh[root@controller ~]# source /etc/keystone/admin-openrc.sh #使环境生效[root@controller ~]# iaas-install-glance.sh[root@controller ~]# iaas-install-nova-controller.sh[root@controller ~]# iaas-install-neutron-controller.sh[root@controller ~]# iaas-install-dashboard.sh

看到此类问题可以删除yum里除local.repo多余文件

直到出现以下（一定是这张图片，要全部安装成功，如果是上面报Yum错误，删除完多余的再刷一遍iaas-pre-host.sh脚本，直到出现完毕！）：

compute节点：

[root@compute ~]# iaas-pre-host.sh #刷完该脚本后需要重启[root@compute ~]# iaas-install-nova-compute.sh[root@compute ~]# iaas-install-neutron-compute.sh

五.登录openstack云平台

在地址栏中输入http://192.168.100.10/dashboard

出现以下图即为成功（用户名：admin  密码：000000）
