openstack搭建
1、虚拟机部署规划
| 主机 | 主机名 | IP规划 | |
|---|---|---|---|
| 实例通讯 | 内部通讯 | ||
| 控制节点 | controller | 192.168.10.144 | 192.168.1.144 |
| 实例节点 | compute | 192.168.10.145 | 192.168.1.145 |
2、硬件配置
| 主机名 | 内存 | 逻辑CPU数量 | 硬盘容量 |
|---|---|---|---|
| controller | 4G | 4 | 80G |
| compute | 4G | 4 | 80G+20G |
3、安装centos7，命名compute/controller
在此，我使用centos7系统，内存给了4G，磁盘空间给了80G和20G两个磁盘，处理器2个，网络为NAT模式
虚拟机设置：
打开虚拟化引擎，并给两个磁盘，是为了给openstack一个安装空间，不可省略
4、配置yum源
- 控制节点controller：
创建目录/opt/centos
配置本地yum源：
上传镜像
配置
##CentOS-7挂载
[root@controller ~]# mount -o loop ./CentOS-7-x86_64-DVD-1511centOS7.iso /mnt/
mount: /dev/loop0 写保护，将以只读方式挂载
##复制
[root@controller ~]# cp -rf /mnt/* /opt/centos
##卸载
[root@controller opt]# umount /mnt/
##XianDian挂载
[root@controller ~]# mount -o loop ./XianDian-IaaS-v2.2.iso /mnt/
mount: /dev/loop0 写保护，将以只读方式挂载
##复制
[root@controller opt]# cp -rf /mnt/* /opt/
[root@controller opt]# umount /mnt/
构建：
[root@controller yum.repos.d]# mkdir centos

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

7、关闭防火墙，并禁用SLINUX
双机配置
[root@compute ~]# systemctl stop firewalld
[root@compute ~]# systemctl disable firewalld
[root@compute ~]# vi /etc/selinux/config
[root@compute ~]# cat /etc/selinux/config# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of three two values:
# targeted - Targeted processes are protected,
# minimum - Modification of targeted policy. Only selected processes are protected.
# mls - Multi Level Security protection.
SELINUXTYPE=targeted [root@compute ~]# reboot
8、修改主机映射
配置解析双机
[root@c ~]# vi /etc/hosts
[root@compute ~]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.10.144 controller
192.168.10.145 compute
