CentOS7部署双节点OpenStack_如何安装openstack双节点

CentOS7部署双节点OpenStack

第一阶段 配置基础虚拟机CentOS7

设置虚拟网络配置

创建虚拟机

1.安装虚拟机配置如上图
2.时区、网卡不需要其他设置
3.镜像以CentOS官网中为主
本篇文章中虚拟机的密码统一为：1

配置虚拟主机

修改网卡

重启网卡

service network restart
1

关闭防火墙

永久关闭防火墙(重启服务器防火墙不会重新开启)

systemctl disable firewalld
1

清空yum源

rm -rf /etc/yum.repos.d/*
1

修改hosts配置

[root@localhost ~]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.10.10 controller
192.168.10.20 compute

克隆bash主机为控制节点、计算节点

按照表格中的IP修改对应的主机IP

修改主机名称

[controller]
[root@localhost ~]# hostnamectl set-hostname controller
[root@localhost ~]# bash
[root@controller ~]#

[compute]
[root@localhost ~]# hostnamectl set-hostname controller
[root@localhost ~]# bash
[root@compute ~]#

挂载镜像、yum配置

【controller】节点配置

挂载镜像

不管什么方法将宿主机中的镜像上传至controller节点就可以

镜像↓

创建文件夹
[root@controller /]# mkdir /opt/centos7
[root@controller /]# mkdir /opt/iaas

挂载第一个镜像
[root@controller /]# mount -o loop CentOS-7-x86_64-DVD-2009.iso /mnt/
mount: /dev/loop0 写保护，将以只读方式挂载
[root@controller /]# cp -rvf /mnt/* /opt/centos7/
[root@controller /]# umount /mnt/

挂载第二个镜像
[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 -rvf /mnt/* /opt/iaas/
[root@controller /]# umount /mnt/

配置yum源

[centos7]
name=centos7
enabled=1
gpgcheck=0
baseurl=file:///opt/centos7
[iaas]
name=iaas
enabled=1
gpgcheck=0
baseurl=file:///opt/iaas/iaas-repo

安装ftp软件

安装vsftpd软件
[root@controller /]# yum install vsftpd -y

修改vsftpd的配置文件 将 引号内的文本追加到vsftpd.conf
[root@controller /]# echo "anon_root=/opt" >> /etc/vsftpd/vsftpd.conf 

开启服务设置为开机自启动
[root@controller /]# systemctl restart vsftpd
[root@controller /]# systemctl enable vsftpd
Created symlink from /etc/systemd/system/multi-user.target.wants/vsftpd.service to /usr/lib/systemd/system/vsftpd.service.
