OpenStack Q版本私有云平台搭建
一、基本环境配置
1.实训室局域网需添加路由访问服务器：
route add 192.168.10.0/24 192.168.1.1
2.yum源配置（http）
（1）yum源备份
mv /etc/yum.repos.d/* /opt/
（2）创建repo文件
主备分别创建文件/etc/yum.repos.d/centos.repo。
touch /etc/yum.repos.d/centos.repo
1)控制节点
echo '
[centos]
name=centos
baseurl=file:///opt/centos
gpgcheck=0
enabled=1
[iaas]
name=iaas
baseurl=file:///opt/iaas-repo
gpgcheck=0
enabled=1' > /etc/yum.repos.d/centos.repo
2)计算节点
echo '
[centos]
name=centos
# baseurl=ftp://192.168.10.10/centos
baseurl=http://192.168.10.10/centos
gpgcheck=0
enabled=1
[iaas]
name=iaas
# baseurl=ftp://192.168.10.10/iaas-repo
baseurl=http://192.168.10.10/iaas-repo
gpgcheck=0
enabled=1 ' > /etc/yum.repos.d/centos.repo
（3）挂载iso文件(主)
1)挂载ceontos镜像
需要先上传镜像
cd /root/;
mount -o loop CentOS-7-x86_64-DVD-1804.iso /mnt/;
mkdir /opt/centos;
cp -rvf /mnt/* /opt/centos/ && umount /mnt/;
2.挂载iaas镜像
cd /root/;
mount -o loop chinaskills_cloud_iaas.iso /mnt/;
cp -rvf /mnt/* /opt/;
umount /mnt/;
(4)搭建http服务器，开启并设置自启
1)控制节点
yum repolist
yum install -y httpd
vi /etc/httpd/conf/httpd.conf
将/var/www 改为/opt
DocumentRoot "/opt"
<Directory "/opt">
AllowOverride None
# Allow open access:
Require all granted
</Directory>
# Further relax access to the default document root:
<Directory "/opt">
systemctl restart httpd;
systemctl enable httpd;
systemctl stop firewalld;
systemctl disable firewalld;
netstat -pant;
2)计算节点
yum clean all;
yum repolist;
（5）配置防火墙和selinux（控制/计算节点）
编辑selinux文件
sed -i 's/SELINUX=enforcing/SELINUX=permissive/g' /etc/selinux/config
关闭防火墙并设置开机不自启
systemctl stop firewalld.service;
systemctl disable firewalld.service;
yum remove -y NetworkManager firewalld;
yum -y install iptables-services;
systemctl enable iptables;
systemctl restart iptables;
iptables -F;
iptables -X;
iptables -Z;
service iptables save;
（6）清除缓存，验证yum源
【controller/compute】
yum clean all;
yum list;
3.编辑环境变量
在controller和compute节点安装iaas-xiandian包：
yum install iaas-xiandian -y
计算节点创建空白分区：
lsblk:查看哪些盘没有分
创建两个空白磁盘空间
fdisk /dev/sdc
n,p,回车,回车,+500G
n,p,回车,回车,+500G
w
编辑修改配置文件/etc/xiandian.openrc.sh
