搭建先电openstack(双节点)

使用两台虚拟机，每个都有两张网卡，如下表

主机名	第一张网卡（NAT）ens33	第二张网卡（仅主机）ens34
controller	192.168.1.10	192.168.10.10
compute	192.168.1.100	192.168.10.100

一、基础配置

关闭防火墙（两台都要做）

[root@controller /]# systemctl stop firewalld
[root@controller /]# systemctl disable firewalld
[root@controller /]# setenforce 0

[root@controller /]# vi /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     #将enforcing修改为disabled
# SELINUXTYPE= can take one of three values:
#     targeted - Targeted processes are protected,
#     minimum - Modification of targeted policy. Only selected processes are protected.
#     mls - Multi Level Security protection.
SELINUXTYPE=targeted

修改host文件（两台都要做）

controller主机

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

compute主机 

[root@compute yum.repos.d]# vi /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.10.10 controller
192.168.10.100 compute

 

二、配置yum源(controller)

上传XianDian-IaaS-v2.2.iso到controller主机

[root@controller ~]# ls
anaconda-ks.cfg  XianDian-IaaS-v2.2.iso
[root@controller ~]# cd /etc/yum.repos.d/
[root@controller yum.repos.d]# mkdir /repo
[root@controller yum.repos.d]# mv * /repo
[root@controller yum.repos.d]# vi a.repo
[c7]
baseurl=file:///cdrom
gpgcheck=0
enabled=1

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

[root@controller yum.repos.d]# mkdir /iaas
[root@controller yum.repos.d]# mount /dev/sr0 /cdrom
mount: /dev/sr0 写保护，将以只读方式挂载
[root@controller yum.repos.d]# mount /root/XianDian-IaaS-v2.2.iso /iaas
mount: /dev/loop0 写保护，将以只读方式挂载
[root@controller iaa
