先电IaaS2.2私有云部署OpenStack

前期准备

ip拓扑

主机名	ip1（NAT）	ip2（仅主机）	硬盘	内存
controller-48	192.168.48.10	192.168.148.10	100G	8G
computer-48	192.168.48.20	192.168.148.20	100G	3G

基础镜像

CentOS-7-x86_64-DVD-2009.iso
chinaskills_cloud_iaas.iso

虚拟机硬件配置

controller

computer

sdb和sdc是分别作为cinder服务和swift服务的存储磁盘。

配置主机名和hosts，关闭防火墙和永久关闭selinux

controller

hostnamectl set-hostname controller && bash
systemctl disable firewalld --now
sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/sysconfig/selinux
sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config
echo "192.168.48.10 controller" >> /etc/hosts
echo "192.168.48.20 computer" >> /etc/hosts
setenforce 0

computer

hostnamectl set-hostname computer && bash
systemctl disable firewalld --now
sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/sysconfig/selinux
sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config
echo "192.168.48.10 controller" >> /etc/hosts
echo "192.168.48.20 computer" >> /etc/hosts
setenforce 0

确保两者可以互通！

格式化compute磁盘（在compute中操作）

1 2	mkfs.xfs /dev/sdb mkfs.xfs /dev/sdc

配置yum源

controller

rm -rf /etc/yum.repos.d/*
cat >> /etc/yum.repos.d/centos.repo << EOF
[centos]
name=centos
baseurl=file:///qianyios/centos
gpgcheck=0
enabled=1
[iaas]
name=iaas
baseurl=file:///qianyios/iaas-repo
gpgcheck=0
enabled=1
EOF

computer

mkdir repo.bak
mv /etc/yum.repos.d/* repo.bak/
cat >> /etc/yum.repos.d/centos.repo << EOF
[centos]
name=centos
baseurl=ftp://192.168.48.10/centos
gpgcheck=0
enabled=1
[iaas]
name=iaas
baseurl=ftp://192.168.48.10/iaas-repo
gpgcheck=0
enabled=1
EOF

挂载iso镜像文件

#控制节点
mkdir /qianyios/centos -p
mount -o loop CentOS-7-x86_64-DVD-2009.iso /mnt/
cp -rvf /mnt/* /qianyios/centos/
umount /mnt/
mount -o loop chinaskills_cloud_iaas.iso /mnt/
cp -rvf /mnt/* /qianyios/
umount /mnt/
yum clean all && yum makecache

搭建ftp服务器

控制节点
yum install vsftpd -y
cat>> /etc/vsftpd/vsftpd.conf <<EOF
anon_root=/qianyios/
EOF
systemctl start vsftpd && systemctl enable vsftpd

验证操作

1.清理yum缓存

1 2	#各节点 yum clean all && yum makecache

2.在文件资源管理器输入ftp://192.168.48.10/

编辑xiandian变量

#各节点
yum install iaas-xiandian -y
#使用sed命令批量去除第一个#注释符为空
sed -i -e 's/^#//'g /etc/xiandian/openrc.sh
使用sed命令批量修改密码默认000000
sed -i -e 's/PASS=/PASS=000000/'g /etc/xiandian/openrc.sh

安装平台基本服务

[root@controller ~]# iaas-pre-host.sh 
[root@compute ~]# iaas-pre-host.sh 
#双节点
reboot
# 可同时执行，执行完毕后脚本会提示重启，不然rabbitmq服务会报错！！！此脚本会初始化虚拟机环境，如修改主机
名、主机映射、时间同步等，自己可去尝试解读脚本，手工搭建平台！！！！，由于重启可能导致平台出现问题可用ssh
连接自己的IP地址重新登陆，只要出现屏幕登录时间以及看到屏幕欢迎界面即可
