openstack双节点部署-CFANZ编程社区

OpenStack云平台搭建需要两个节点，一个是controller（控制节点），另一个是compute（计算节点）。

控制节点（controller）	一块200G硬盘	第一张网卡使用：192.168.100.10 第二张网卡使用：192.168.200.10
计算节点（compute）	一块200G硬盘＋一块100G硬盘	第一张网卡使用：192.168.100.20 第二张网卡使用：192.168.200.20

云平台搭建需要使用centos7.5及7.0版本的镜像和chinaskills_cloud_iaas.iso镜像

镜像提供如下：部署所需的两个镜像

正式搭建openstack云平台

controller节点配置

首先我们使用CRT进行连接192.168.100.10的ip进行上传镜像至节点controller中：

openstack双节点部署_centos_64

openstack双节点部署_centos_65

关闭防火墙和selinux：

[root@controller ~]# systemctl stop firewalld        #关闭防火墙
[root@controller ~]# systemctl disable firewalld        #设置防火墙开机不自启
[root@controller ~]# setenforce 0        #临时关闭selinux防火墙，0表示关闭，1表示开启
[root@controller ~]# getenforce        #查看selinux防火墙的状态
Permissive

openstack双节点部署_mysql_66

[root@controller ~]# vi /etc/selinux/config         #非临时性

进入之后修改SELINUX为

openstack双节点部署_yum源_67

查看刚才上传的镜像：

openstack双节点部署_centos_68

进行挂载镜像：

[root@controller ~]# mount -o loop CentOS-7-x86_64-DVD-1804.iso /mnt/
[root@controller ~]# mkdir /opt/centos
[root@controller ~]# cp -rf /mnt/* /opt/centos/
[root@controller ~]# umount /mnt/
[root@controller ~]# mount -o loop chinaskills_cloud_iaas.iso /mnt/
[root@controller ~]# cp -rf /mnt/* /opt/
[root@controller ~]# umount /mnt/

openstack双节点部署_centos_69

yum源文件处理

移除yum源：

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

openstack双节点部署_mysql_70

写入yum源文件：

[root@controller yum.repos.d]# vi local.repo

写入如下内容：

[centos]
name=centos
baseurl=file:///opt/centos
gpgcheck=0
enabled=1
 
[iaas]
name=iaas
baseurl=file:///opt/iaas-repo
gpgcheck=0
enabled=1

进行查看：

openstack双节点部署_yum源_71

清除yum源缓存，验证yum源，下载所需软件包：

[root@controller yum.repos.d]# yum clean all        #清除yum源缓存
[root@controller yum.repos.d]# yum repolist        #列出所有可用的yum源
[root@controller yum.repos.d]# yum install -y vim vsftpd iaas-xiandian   #安装所需的软件包

openstack双节点部署_mysql_72

配置vsftpd：

[root@controller yum.repos.d]# echo anon_root=/opt/ >> /etc/vsftpd/vsftpd.conf #设置匿名访问
[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

openstack双节点部署_centos_73

修改脚本：

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

原文件内容：

openstack双节点部署_yum源_74

需要删除所有第一行注释：

在非注释模式下按下：CTrl+v然后按下shift+g然后再按下D即可删除注释

如下图：

openstack双节点部署_mysql_75

取消注释之后对其进行修改：

openstack双节点部署_centos_76

openstack双节点部署_yum源_77

openstack双节点部署_centos_78

openstack双节点部署_yum源_79

openstack双节点部署_centos_80
