openstack学习之路（搭建部分）

网络：双网卡搭建

contaroller:

vi /etc/sysconfig/network-scripts/ifcfg-ens32

IPADDR=192.168.100.10

PREFI=24

GATEWAY=192.168.100.1

vi /etc/sysconfig/network-scripts/ifcfg-ens33

IPADDR=192.168.200.10

PREFI=24

GATEWAY=192.168.200.1

compute:

vi /etc/sysconfig/network-scripts/ifcfg-ens32

IPADDR=192.168.100.20

PREFI=24

GATEWAY=192.168.100.1

vi /etc/sysconfig/network-scripts/ifcfg-ens33

IPADDR=192.168.200.20

PREFI=24

GATEWAY=192.168.200.1

1.使用命令行方式设置主机名，防火墙以及 SELinux 设置如下：

（1）设置控制节点主机名 controller；计算节点主机名：compute。

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

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

各个节点关闭防火墙，设置开机不启动。

[root@controller ~]# systemctl stop firewalld

[root@controller ~]# systemctl disable firewalld

[root@compute ~]# systemctl stop firewalld

[root@compute ~]# systemctl disable firewalld

（3）设置各个节点 selinux 状态为 permissive。

[root@controller ~]# setenforce 0

[root@compute ~]# setenforce 0

2.使用命令查询控制/计算节点的主机名。

[root@controller ~]# hostname

[root@compute ~]# hostname

3.使用命令查询控制/计算节点 selinux 的状态。

[root@controller ~]# systemctl status firewalld

[root@controller ~]# getenforce

[root@compute ~]# systemctl status firewalld

[root@compute ~]# getenforce

4.在控制节点上通过 SecureFX 上传两个镜像文件CentOS-7-x86_64-DVD-1511.iso， XianDian-IaaS-v2.2.iso 到 opt 下，使用命令创建/opt 下两个目录，并将以上镜像文件分别挂载到上述两个目录下，并使用命令查看挂载的情况（需显示挂载的文件系统类型和具体的大小）。

[root@controller ~]# mkdir /opt/{centos，iaas}

[root@controller ~]# mount -o loop CentOS-7-x86_64-DVD-1511.iso /opt/centos/

[root@controller ~]# mount -o loop XianDian-IaaS-v2.2.iso /opt/iaas/

[root@controller ~]# df -Th

5.配置控制节点本地 yum 源文件 local.repo ，搭建 ftp 服务器指向存放 yum源路径；配置计算节点 yum 源文件 ftp.repo 使用之前配置的控制节点 ftp 作 为 yum 源，其中的两个节点的地址使用主机名表示。使用 cat 命令查看上述控制/计算节点的 yum 源全路径配置文件。

[root@controller ~]# rm -rfv /etc/yum.repos.d/*

[root@controller ~]# vi /etc/yum.repos.d/local.repo

[centos]

name=centos

baseurl=file:///opt/centos

enabled=1

gpgcheck=0

[iaas]

name=iaas

baseurl=file:///opt/iaas/iaas-repo

enabled=1

gpgcheck=0

[root@compute ~]# vi /etc/yum.repos.d/ftp.repo

[centos]

name=centos

baseurl=ftp://controller/centos    或者使用IP地址

enabled=1

gpgcheck=0

[iaas]

name=iaas

baseurl=ftp://controller/iaas/iaas-repo    或者使用IP地址

enabled=1

gpgcheck=0

7.在控制节点和计算节点分别安装 iaas-xiandian 软件包，完成配置文件中基本变量的配置，并根据提供的参数完成指定变量的配置。

[root@controller ~]# yum install iaas-xiandian -y

[root@controller ~]# vi /etc/xiandian/openrc.sh

[root@controller ~]# grep ^[^#] /etc/xiandian/openrc.sh

[root@compute ~]# yum install iaas-xiandian -y

[root@compute ~]# scp root@controller:/etc/xiandian/openrc.sh

[root@compute ~]# grep ^[^#] /etc/xiandian/openrc.sh

8.磁盘分区

[root@controller ~]# lsblk 

[root@controller ~]# fdisk /dev/sdb

n

p

enter

enter

+100G(重复一次)

[root@controller ~]# lsblk

之后只要跑脚本就好了，只要前面没错误，后面一般纯跑脚本
