云计算基础平台iaas（openstack）超级详细搭建（二）
根据上一篇的环境已经创建安装成功，下面开始正式进入我们的搭建环节
使用的secure CRT仿真终端，方便，优秀的工具
配置linux 和secure CRT 连接参考博客
https://blog.csdn.net/qq_28513801/article/details/90138255
1.1 克隆一个节点 使用ctrl+o 或者直接选中 右键复制便可以
我们首先进去查看下有几块网卡 并进行配置：
关于网卡的配置文件详解 请查看这个博客
https://blog.csdn.net/qq_28513801/article/details/90138255
开始配置我们的网卡
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 ~]# hostnamectl set-hostname controller
[root@controller ~]# bash
[root@controller ~]# hostnamectl
Static hostname: controller
Icon name: computer-vm
Chassis: vm
Machine ID: b9c2ba6d4bb243b0a22f2a587377b60f

[root@controller ~]#
[root@compute ~]# hostnamectl set-hostname compute
[root@compute ~]# bash
[root@compute ~]# hostnamectl
Static hostname: compute
Icon name: computer-vm
Chassis: vm
Machine ID: b9c2ba6d4bb243b0a22f2a587377b60f

[root@compute ~]#
controller & compute 两个节点都需要进行该操作
接下来修改网络配置文件
[root@controller ~]# vi /etc/sysconfig/network-scripts/ifcfg-enp0s3

BOOTPROTO=static
DEFROUTE=yes
PEERDNS=yes
PEERROUTES=yes
IPV4_FAILURE_FATAL=no

NETMASK=255.255.255.0
########################这里一定要记住 第二块网卡 一定不能配置网关
同理compute 节点也是一样
[root@compute ~]# vi /etc/sysconfig/network-scripts/ifcfg-enp0s3
TYPE=Ethernet
BOOTPROTO=static
DEFROUTE=yes
PEERDNS=yes
PEERROUTES=yes

NETMASK=255.255.255.0
[root@controller ~]# systemctl restart network
[root@compute ~]# 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
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
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

（5）清除缓存，验证yum源
[root@controller centos]# yum clean all
Loaded plugins: fastestmirror
Cleaning repos: centos iaas

Cleaning up list of fastest mirrors
[root@controller centos]# yum list

[root@controller centos]#
编辑文件/etc/xiandian/openrc.sh,此文件是安装过程中的各项参数，根据每项参数上一行的说明及服务器实际情况进行配置。
############这里配置完后 可以使用sed 命令进行过滤 去除每行开头的#号
##可使用cat openrc.sh | sed "s/.//" > openrc.sh 去掉注释#)
##然后使用scp命令发送到另一个节点
###scp openrc.sh root@compute:/etc/xiandian
###这里是配置文件
[root@controller centos]# vi /etc/xiandian/openrc.sh

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
最好先熟悉shell编程和openstack基础配置命令
