1.2 配置网络、主机名

controller & compute 两个节点都需要进行该操作

[root@controller ~]# systemctl restart network

这里要先把我们的centos和iaas镜像上传至我们的linux虚拟机中
在这里插入图片描述
创建两个文件夹

 [root@controller opt]# mkdir centos iaas 
 [root@controller opt]# ls
  centos  CentOS-7-x86_64-DVD-1511.iso  iaas  XianDian-IaaS-v2.2.iso
  [root@controller opt]#

配置映射文件

   [root@controller centos]# vi /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.100.10  controller
192.168.100.20  compute
同理另外一个节点也要配置

在这里插入图片描述

1.3配置yum源

#Controller和compute节点

（1）由于实验环境直接把
（2）创建repo文件

【controller】
在/etc/yum.repos.d创建centos.repo源文件

[root@controller ~]# cd /etc/yum.repos.d/
[root@controller yum.repos.d]# ls
CentOS-Base.repo  CentOS-CR.repo  CentOS-Debuginfo.repo  CentOS-fasttrack.repo  CentOS-Media.repo  CentOS-Sources.repo  CentOS-Vault.repo
[root@controller yum.repos.d]# rm -rf *
[root@controller yum.repos.d]# vi  local.repo
[centos]
name=centos
baseurl=file:///opt/centos
gpgcheck=0
enabled=1
[iaas]
name=centos
baseurl=file:///opt/iaas/iaas-repo
gpgcheck=0
enabled=1

然后把镜像挂载到/mnt/并复制到指定的目录/opt/centos/


[root@controller opt]# mount -o loop CentOS-7-x86_64-DVD-1511.iso /mnt/
mount: /dev/loop0 is write-protected, mounting read-only
[root@controller opt]# cp -rvf /mnt/* /opt/centos/
[root@controller opt]# umount /mnt/
[root@controller opt]# mount -o loop 
centos/                       CentOS-7-x86_64-DVD-1511.iso  iaas/                         XianDian-IaaS-v2.2.iso
[root@controller opt]# mount -o loop XianDian-IaaS-v2.2.iso /mnt/
mount: /dev/loop0 is write-protected, mounting read-only
[root@controller opt]# cp -rvf /mnt/*  /opt/iaas/

在compute节点 配置yum文件

[root@compute opt]# ls
[root@compute opt]# rm -rf /etc/yum.repos.d/*
[root@compute opt]# vi /etc/yum.repos.d/local.repo
[centos]
name=centos
baseurl=ftp://192.168.100.10/centos
gpgcheck=0
enabled=1
[iaas]
name=iaas
baseurl=ftp://192.168.100.10/iaas/iaas-repo
gpgcheck=0
enabled=1

(3)关闭防火墙和设置selinux

[root@controller centos]# systemctl stop  firewalld 
[root@controller centos]# systemctl disable  firewalld     
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
Removed symlink /etc/systemd/system/basic.target.wants/firewalld.service.
[root@controller centos]# 
[root@controller centos]# setenforce 0
[root@controller centos]# getenforce 
Permissive
[root@controller centos]# 

[root@compute opt]# systemctl disable  firewalld     
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
Removed symlink /etc/systemd/system/basic.target.wants/firewalld.service.
[root@compute opt]# systemctl stop   firewalld            
[root@compute opt]# setenforce 0
[root@compute opt]# getenforce 
Permissive
[root@compute opt]#

(4)在controller节点搭建ftp服务器,并把opt目录作为ftp目录的共享根目录（修改ftp配置文件）

[root@controller centos]# yum install -y vsftpd
Loaded plugins: fastestmirror
centos                                                                                                                    | 3.6 kB  00:00:00

针对于上述空白分区可采用linux老牌的分区工具fdisk或者使用parted命令
CentOS7的安装与CentOS6.5的安装有明显的区别。在CentOS7安装过程中，设置分区都需要一个挂载点，这样一来就无法创建两个空白的磁盘分区作为cinder服务和swift服务的存储磁盘了。
所以我们应该在系统安装过程中留下足够的磁盘大小，系统安装完成后，使用命令parted划分新分区，然后使用mkfs.xfs进行文件系统格式化，完成空白分区的划分。具体命令如下：

[root@compute ~]# parted /dev/md126                                     
(parted) mkpart swift 702G 803G    //创建swift分区，从702G到803G                                                  
 [root@compute ~]# mkfs.xfs /dev/md126p5

基本环境配置完成后开始安装我们的服务。将会在下一篇博客写出
